@Xavier Leandro thanks for your reply. I got to the site through google and im waiting for the hacking stuff now. Takes a while so I will reply here later with my results.
Nobody at my job can teach me any of this 🤦♂️ I have to go to UA-cam your channel to learn how to be a hvac Service Tech it’s frustrating man thanks ac service tech
We all just try to invest in ourselves as best we can. Thanks John Doe for letting me know! I am glad that the videos are helping in your current situation!
I bought a Genteq 5SBA39FLP8013 ECM blower motor to replace the Broad Ocean motor which stopped working in my air handler. The Genteq is an X13 with 5 speed taps as shown in the video. I decided to test it before going to the trouble of mounting it in the air handler. I laid it on its side next to the air handler and connected the wiring. The thermostat was set to fan only. When I turned on the power the shaft began to spin for about 1 second and shut off and then a few seconds later it came back on and shut off and continued this pattern until the power was shut off. My neighbor's son in law is a HVAC technician, so I called him and explained the problem. He told me that the motor detects the load that is on it and adjusts for that load to maintain a steady speed. It needs to have the blower wheel on it and be mounted in the blower housing in order to detect a load. I installed it in the air handler and it works perfectly. I don't know why this information is not in the video and why the motor in the video is not showing this problem.
FYI The Genteq X13 will determine a CW or CCW rotation on it's own when powered on the first time. This can take a minute as it figures load, direction and speed. The sensor in mine went bad (12 years old) and would hunt back and forth only. Fan never did get up to speed.
I LOVE UA-cam!!!!! The motor on my furnace went out. An AC/Heat company said it would cost over two thousand bucks to fix it, due to the type of motor ECM. which cost around 1500.00 dollars. So like always I went to youtube to see how hard would it be to replace the motor. To my surprise, there were many videos showing how to do it. Looked pretty simple to me. I found a place that sells rebuilt motors and found exactly what I needed for $300 dollars no tax or delivery charges. Just got the motors and fixed my unit in less than two hours, most of that time was cleaning the furnace. The wife is happy and I am very happy. Thank you, UA-cam you're the best!!!
HELLYA! Paid $85 for a service call for the guy to lie to me about the issue. Watched AC Service Tech video, got the skinny, back up in the attic troubleshoot to a likely blown Cap on the ECM module, order an exact replacement off Ebay for $82. 3 hours of YT videos, 1 hour to Trane shop to be denied, 1 hour surfing Ebay, then 10 minutes mounting replacement ECM and I'm UP AND RUNNING! It was a total of 6 screws to fix!! You saved me $2400!!!!!!!!!!!!!!!!!!!!!!!! Signed up for Patreon. I'm not an HVAC pro so would have preferred a one-time payment.
Your machine could have been out off warranty. You were paying parts and labor. Did you know it was the blower motor BEFORE he got there? I'm glad you fixed it. But don't bash the tech. Most of the time the company sets the prices..we just do our part and diagnose issues for customers.. plus it's an attic. Salute
@@hliz8818Company, Tech or both, they tried to get $2500 for the blower replacement or better yet a $8000 full system replacement. It's a year later and I'm out $75 in parts and my HVAC is running great. I spent more time watching this video than the repair took. If that's how you "just do our part" you might want to think about how you sleep at night.
No doubt, glad you can do it yourself but a licensed company has a certain value for their time. Incidentally I've been researching and there are conversion boards from ecm to psc. Suppliers won't help you fix old stuff, only push new sales
I had a similar experience with the capacitor being the failed part but a tech was not involved. After looking at UA-cam videos for 2 days (I’m retired) there was a throwaway comment at the end of one that gave me the clue. That was 3-4 years ago and it’s still going (but who knows for how much longer). I think the takeaway from your story is if you have the time just go ahead and get the part when it fails (assuming you can confirm which one that is), change it out yourself (follow the diagram), save on the labor, fix the original if you can and keep it as a spare.
Unbelievably helpful, THANK YOU!!! I literally got 2 quotes - one was for $3,850 to replace motor and ECM and the other company said there was not available replacement available and said I absolutely MUST buy new unit which was $10-12k. I just replaced the motor and ECM with parts from Supply House for $750. However, from your video I figured out that it was the inrush current limiter that had blown and bought new component for $5.07, so will either save as backup or sell used but working on eBay and probably get $200-300 of my money back, I would have sure paid it.
I got myself into the trade watching UA-cam. AC service tech knows their stuff. I started at an apartment complex as a groundskeeper and within two years I was lead tech. Now, I’m in residential working for a really good company that really doesn’t have time to train. Most companies don’t have the resources (especially in todays economy with everything getting so expensive), to send two techs to a house so one can learn. So you either start as a helper making $10/hour where you’ll be on install or you learn the stuff and go in making $30/hour on service. Learn this stuff. You won’t be rich but you’ll make a comfortable living. I’ll be moving into industrial and commercial soon. We do commercial now but I’m looking forward to working on more complicated things like chillers and oil heaters.
Congratulations Shawn on the marriage, I wish you and your wife a lifetime of happiness. Brother I’ve been following from the beginning and will continue to follow your videos. I enjoy the way you approach content and then share it. Semper Fi brother!
Your electrical troubleshooting videos have been helping me on a daily basis, and your book has been a huge help in the field for me to look back on instead of calling my techs. It would be amazing if you made a book on electrical troubleshooting, having a good guid handy really helps out in a jam for a newbie on call lol
Thanks for sharing Craig. I tell all my trainees to watch your videos. It’s amazing what this industry has become with everyone sharing information thanks to people like you putting in the time. Great video sir!! 😎
Thank you so much for the information on this ECM. I'm a maintenance technician at a retired community and I have ran into some problems with some of my air handler blower with this ecm. So watching this video gives me a little more information on what to look for. Again thank you for your fine work & information!
Great imformational video. Had an X-13 motor running constantly, without 24v, about a month ago. I replaced the entire motor. I was unaware untill watching this video that you could replace the module only. Your videos are always helpful.
I just started out in this field and luckily I have been lucky enough to work with someone who has 30 + years experience.. But he will make the time to teach you if you’re interested and trying. Not trying to wast time
I live in the Chicago area, lots of supply houses, but on a Saturday night at 100 bucks + an hour the bill can be ridiculous. I've also had supply houses be out of stuck. I always carry a standard PCM motor for older style motors. At -10 outside the people don't want to hear you'll be back tomorrow if you can find the part. So, I will install the PCM motor and hot wire it low for heat and high for AC.to give them service. I know some guys that carry an old working motor just to give service and you can take your time getting the right part. I carry a 1/2 hp. does 1/6 thro 1/2 and 90% of my calls.
Absolutely, I wish I had all the online training, articles, and videos when I started. I could have learned a lot faster when I started in the trade, thanks!
I have a carrier unit with the broad ocean ecm you have in the video. I have had an issue 3 times now where all of a sudden when the ac turns on the inducer/blower motor doesnt turn on. The first time I got it working, but to be honest not sure what I did is all I did was test just like you said and when I hooked back up it worked like nothing had ever happened. It then did it again several months later. I was out of town but the wife and kids were at home and I just called an hvac tech to come and look at it since I couldn't trouble shoot. I had the wife simply kill power to the whole unit and when the tech got their the next day he flipped the power back on and it worked with no issues. Basically paid him for a trip to come to my house and turn it on. Well now it has been about 6 months since hat time and it has done it again. Of course I am out of town, but I will trouble shoot when I get back. Sorry for being such long winded but wanted to give you as much info as possible. So you have any idea why it would be intermittently not working. Why would it not work then when turned off for a period of time or when testing it it just all of a sudden works like normal again. I had thought the first times were due to power surges and actually installed a whole house Honeywell surge protector about 3 weeks ago so it wouldn't happen again. This last time, today my wife said there were not any power surges. Any help would be appreciated.
You may have an intermittent problem with that blower motor. That means it’ll work when it wants to and it won’t work when it wants to. That’s a sign of a bad module or blower motor or both.
I see a lot of ECM motors on Fan powered boxes (VAV's) and this is the best video with explanations I have seen to date. Usually, the factory recommendation is to use the "Tech-Mate" adapter and call it good. Thanks for the great video.
Great information Greg! Just to add another tidbit of information, I had purchased a generic X13 preprogrammed ECM motor, but the motor ran backwards. There are three stator windings which are very similar to a 3-phase motor. One can cut any two of the three wires on the connector going to the stator windings, reverse the leads and the motor will run in the reverse condition. I don't recommend this, but it will work as I've done it to get a unit to work. Fortunately, the motor speed was very close to the original.
Some of those motors have a way to program it to reverse the direction of the motor. Also, the motor is a three phase motor, but that doesn't mean you can hook it up to three phase straight from the breaker panel as a temporary work around. I tried this as a last ditch effort to get the AC blowing again, and the windings started to cook. We were over 80 miles offshore so getting a replacement wasn't going to be quick. Thankfully, the field had a crew boat that was making a run to the beach for resupply the next day.
Excellent vid. IT would be nice to know what application of the 24 VAC motor speed control signal actually do, and how one goes about "programming" which speeds are active. It is clear from your vid that only 1 control signal is to be applied at a time. What if the air handler controller feeds 2 at a time?
This video was fantastic and helped me diagnose some issues I was having with my blower fan. Thanks for putting this together! Very informative and very helpful. Keep up the great work!
Perfect explanation and understanding of how to service these motors. I have been trying to find something like this for a while now and you nailed it. Thanks man.
Some of the X13 controllers have an OFF Delay (30sec-3min) built in. My ComfortMaker (Carrier) does this. The only way to stop it is replace the control board without the OFF delay.
Great video! Too bad most control modules are potted. I do component level repairs on just about everything, so it bothers me when manufactures make things disposable. I liked that you said that the MOV is replaceable. Hopefully some technicians will have good soldering skills and will replace them rather than swapping out the module and/or motor. I have worked on some large 3 phase VFD drives for big commercial air handlers, and most of the time its poor soldering and capacitors. The VFDs that I work on are external, and are not potted. Of course there are no schematics, so it is sometimes a challenge. Keep up the great work. Your book is great - I purchased it about a year or so ago. Thank You.
Thank you! You're a saint for bringing this secret information to the people! And to clearly explained. The manufacturers and installer/dealers are in cahoots to make it hard for the owners of the appliances to handle their own hardware failures. I don't much like situations where early failures bring profit to someone else, after I shelled out for the equipment. I'm not saying everyone should try this at home, but if you are technically educated, it's nice to have the simple facts so you can take care of issues.
My ECM had magnets detached from the rotor. Cleaned off the junk glue film remaining on the rotor and magnets, and re-affixed them with epoxy, original orientation, spacing. Motor working fine again. Thank GE, Beloit and Junktek or whoever owns this now Genteq for stupid glue application. Even multirotors have the magnets arranges so they cannot be thrown off.
You always do great training videos, but this one is one of my favorites. Unfortunately I have already ran across a OEM replacement motor that was programmed wrong, not for sure if it was the manufacturer or the distributor (lot of distributors are able to program motor with OEM specs). Since the motor was under warranty, the service call was negative profit for labor.
Thanks for this. The industry charges huge margins for relatively inexpensive parts from Mexico or even China and then we get charged double that by the less scrupulous service technicians. Here in Canada things are worse as the parts suppliers won't sell to the public. I fixed my furnace blower for $25 (cost of five thermistors plus overnight Fedex from DigiKey) after being quoted $1,500 for a new unit. I wish I could find a tech like the creator of this video but, sad to say, they are few.
Ac company came to fix our unit thought it was the blower assembly, then the board find out the yellow wire to the thermastat had voltage on it all the time. Swapped with another extra wire in the harness everything is good.
Only to add that the “in-rush current limiter” you point to in the electronics module is called a Metal Oxide Varistor - and as you said, can be field replaced with relative ease.
I’m about to graduate from HVAC course but my IBM went out and the tech that came out did a resistance test on the module and he said it was at 18 ohms but normal limits should be between 10 and 20 so he said it was starting to fail. He replaced the whole blower with a new one that didn’t come with a module on it. So I’m the future I can check the resistance of the motor itself without dealing with the module although the module is cheaper to replace than a motor.
Great video on ECM's, I hope you put out more video's on Broad Ocean and Rescue motors (maybe you did already??). I would change your explanation on the motor potentially overheating if there's an airflow restriction because motors draw less current with an obstruction (less work as your not pushing as much air - less work = less amperes). I subscribed, looking forward to watching more technical videos!
Just had a first... Payne furnace, newer unit with a broad ocean ECM that wouldnt run so coil froze up. Found circuit board is only supplying 20V to speed tap. Apply 24 direct from transformer, motor fires right up. Apparently the modules are very sensitive and require the full 24V signal.... gotta come up with a circuit board under warranty now🤦🏼♂️
This was a very helpful video my gosh. Do you happen to have a video showing the step by step to swapping an ECM motor to a PSC motor that you would typically carry on the truck?
awesome video, thank you so much for sharing... would you be more incline to replace just the module or the whole motor on an ECM Genteq , if the motor is constantly running....
My ecm motor went out after a transformer blew up in the neighborhood(caused a power outage). Visually inspecting everything in the module looks fine. How do you know what number is a good number when reading the motor part (for resistance)?
Great informative video. Just had a question. When my ecm is plugged in, it’s hard to turn by hand but when I disconnect the ecm. It moved freely. Does this mean I have a bad ecm or bad blower? Should I just replace both?
I would love to see a similar video done for the GENTEQ 5SBA39GLV5000 EON. I've replaced one module already with a used Ebay find with the motor about 4-5 years ago and am back in the same boat replacing that one. Just trying to limp this old equipment along untill it just isn't worth it anymore. The reason I would find it interesting is that the low voltage connection on these has 13 wires and a control board with dip switches that a set your CFMs, some ramping profiles and aux heat speed. Last time I replaced the board and the module for good measure, but this time aroung Im pretty sure its the module, as it occasionally starts running and does a sortof "searching" behavior before it just gives up altogether. I would love to know if there is any common fixable problems with these as I'm about to become the proud owner of two backup modules, motors and one control board.
Where I live these motors are 1000 bucks I have been kicked out of customer house because of price of the part I don't even mark these motors up it's grate to have high efficiency but there is no savings if the savings have been spent on repairs
Can you take amps readings? Also can a continuity test be done on ecm motor connection points or controller connection points? Would manufacturer have the specs on those readings?
Yet another win from AC service tech. Just swapped my module, unfortunately the return air vent was making the motor run harder…time for a louvered door
Good afternoon. I have a Lennox xc17 that is now out of warranty and in need of it's 4th ecm motor. I am considering replacing it with a psc motor and a relay. However, to keep things simple I am also considering the rescue ez13 motor as a replacement. What are your thoughts regarding the ez13 and it's reliability? Also will I still be able to use the Lennox lcd thermostat that came with the xc17 if I switch to the psc? Thank you and any help is appreciated.
I have a Carrier F4BC model and it will not stop running. I have to shut it off at the circuit breaker panel. I pulled the thermostat roo and it keeps running, so I'm thinking it's the circuit board on the motor. Probably a relay???What do you think? Thank's.
Craig I had a need problem brand new furnace motor ramping up cw then stopping then turning cw then the furnace would go out on high limit this indicates a bad motor
I have a question that I hope you might be able to shed some light on. We purchased a new home about 2.5 years ago. AC and heat has run fine for that time frame. Last night I got an alert from Nest that it ran for a longer than normal time and temp did not come down. I was gone all day and discovered the unit was not circulating air. I checked all the common stuff and it was running so I put it back together late at night. Mid day today same thing, no circulation. I pulled cover back off to find the capacitor (did not know there are now ECM's on them and discovered the blower motor ground was just hanging and had never been bolted down. it was just barley touching a bolt, but is it possible for 2.5 years this was operating normally with no ground on the blower motor (or very lightly touching)? I know sometimes it can use other grounding ways, but found it odd. Thank you and I am interested to hear your thoughts.
Does anyone know the socket size used to remove 2 bolts holding the ECM module to the Genteq X13 motor? My female friend is going to try to do the job herself and want to make sure she has all the tools before starting the job. Thanks
So what is the board called on the broad ocean motor that monitors the rotation/speed?!? So I had a motor on the fritz…swapped with a good ECM module, tested the leads like in your video and the windings tested good…if it was the circular board? What’s it called to try and source it?….(tries to look up parts catalog of numbers)
I have an x-13 that will not stop running even without the 24 volt signal wire. I have isolated the issue to the ecm. So I will have to get a certified tech to replace the ECM because it has to be programmed? Is there any way to buy one programmed for a specific system? I don't think the original installers of my system even checked actual air flow
My furnace blower motor has an ECM module that was just replaced. I still need to help start it by spinning the fan with my hand. Once it is up and running it will stay running. I always just keep my fan on because of this. Any ideas why it won't start by itself though when I turn on the heat?
First of all your videos are great. I don’t usually subscribe but I felt compelled to do so after watching two of your videos. What is the expected resistance 1/2 Hp 208/230V X13 motor. I’m getting 12.9 ohms on all. Sorry I’m sure you already answered in comments here or elsewhere but I don’t see how to search comments.
I had a X13 module that was only receiving 21 volts from the board so I verified the transformer was on the correct voltage leads and the transformer was only putting out 21 volts. Could that cause the module to not start up? It wants to start but kind of jerks back and forth. I brought it home and going to apply 24-26 volts and 240 volts to it to see if it will run. Or should I just replace it and the transformer?
They could have made it repairable by any entry level electronics tech without the potting (epoxy resin poured on the board) for $10 worth of parts. We could keep and repair the cores but removing that stuff is almost impossible.
What voltages do you expect to get out of the module and is there a way to connect power to the motor for temporary without the module? Maybe some type of universal module you can pop in there until you get the new part?
I replaced just the module once and it blew up as soon as power was turned on with no call. I can only assume something may have been wrong with the windings, I didn't check prior to swapping module. I did the walk of shame back to the supply house...lol
Can anyone tell me what the FM abbreviation stands for? I deal with a lot of these modules, mostly FM07, FM19, FM20, FM38, and others. But I can find no reference to the FM abbreviation online. Any help is appreciated
@@YuriSoul2222 it’s all good it’s usually worth the wait, and sometimes the only place you can get certain answers. Even though this one didn’t really pan out 😂
Please help. I was checking a X13 blower motor and it was ramping up and ramping down like you showed in the video so we I tolld tje costumer they needed a new blower motor. Well when I was checking the low voltage on the motor I was getting 28 volts on terminal #1 and #5 on the low voltage side at the same time, It only has those two speeds. So is that normal? Am I supposed to get 28 volts on #1 and #5 simultaneously when I check it to commun?
I’m a new “watcher” , but definitely an old guy . 43 years and still getting out there. I recall that supposedly there is one component on the GN 24 ECM module that can be replaced. I would love to prevent my customers from paying $1000 for a new motor and module. I believe it is a IRQ 20 , 141Q Capacitor or resistor. Any suggestions?
My blower motor is running very weak that I can't feel any airflow at the vents but when I reset the unit and power it back on it works at high speed and gives me great airflow but only for 10 minutes or so before it shuts back down to slow speed.... Is this generally a problem with the module/motor or could it potentially be an issue with the control board?

Most technicians are part changers. Learn all you can :)
Read books and learn on your own..we are in a field that never stop learning. Also go to Expos and trade shows. Any training you can go too do it.
We all just try to invest in ourselves as best we can. Thanks John Doe for letting me know! I am glad that the videos are helping in your current situation!
I agree, must of my co workers are great at what they do but they don't know the real deep details on how this stuff works
Dammm I did a service call and the motor kept spinning even tho the ts was off, now I know why thanks boss couldn’t help that day 🤨
I bought a Genteq 5SBA39FLP8013 ECM blower motor to replace the Broad Ocean motor which stopped working in my air handler. The Genteq is an X13 with 5 speed taps as shown in the video. I decided to test it before going to the trouble of mounting it in the air handler. I laid it on its side next to the air handler and connected the wiring. The thermostat was set to fan only. When I turned on the power the shaft began to spin for about 1 second and shut off and then a few seconds later it came back on and shut off and continued this pattern until the power was shut off. My neighbor's son in law is a HVAC technician, so I called him and explained the problem. He told me that the motor detects the load that is on it and adjusts for that load to maintain a steady speed. It needs to have the blower wheel on it and be mounted in the blower housing in order to detect a load. I installed it in the air handler and it works perfectly. I don't know why this information is not in the video and why the motor in the video is not showing this problem.
FYI The Genteq X13 will determine a CW or CCW rotation on it's own when powered on the first time. This can take a minute as it figures load, direction and speed. The sensor in mine went bad (12 years old) and would hunt back and forth only. Fan never did get up to speed.
I LOVE UA-cam!!!!! The motor on my furnace went out. An AC/Heat company said it would cost over two thousand bucks to fix it, due to the type of motor ECM. which cost around 1500.00 dollars. So like always I went to youtube to see how hard would it be to replace the motor. To my surprise, there were many videos showing how to do it. Looked pretty simple to me. I found a place that sells rebuilt motors and found exactly what I needed for $300 dollars no tax or delivery charges. Just got the motors and fixed my unit in less than two hours, most of that time was cleaning the furnace. The wife is happy and I am very happy. Thank you, UA-cam you're the best!!!
What site was it?
HELLYA! Paid $85 for a service call for the guy to lie to me about the issue. Watched AC Service Tech video, got the skinny, back up in the attic troubleshoot to a likely blown Cap on the ECM module, order an exact replacement off Ebay for $82. 3 hours of YT videos, 1 hour to Trane shop to be denied, 1 hour surfing Ebay, then 10 minutes mounting replacement ECM and I'm UP AND RUNNING! It was a total of 6 screws to fix!! You saved me $2400!!!!!!!!!!!!!!!!!!!!!!!! Signed up for Patreon. I'm not an HVAC pro so would have preferred a one-time payment.
Your machine could have been out off warranty. You were paying parts and labor. Did you know it was the blower motor BEFORE he got there? I'm glad you fixed it. But don't bash the tech. Most of the time the company sets the prices..we just do our part and diagnose issues for customers.. plus it's an attic. Salute
@@hliz8818Company, Tech or both, they tried to get $2500 for the blower replacement or better yet a $8000 full system replacement. It's a year later and I'm out $75 in parts and my HVAC is running great. I spent more time watching this video than the repair took.
If that's how you "just do our part" you might want to think about how you sleep at night.
No doubt, glad you can do it yourself but a licensed company has a certain value for their time. Incidentally I've been researching and there are conversion boards from ecm to psc.
Suppliers won't help you fix old stuff, only push new sales
I had a similar experience with the capacitor being the failed part but a tech was not involved. After looking at UA-cam videos for 2 days (I’m retired) there was a throwaway comment at the end of one that gave me the clue. That was 3-4 years ago and it’s still going (but who knows for how much longer). I think the takeaway from your story is if you have the time just go ahead and get the part when it fails (assuming you can confirm which one that is), change it out yourself (follow the diagram), save on the labor, fix the original if you can and keep it as a spare.
Unbelievably helpful, THANK YOU!!! I literally got 2 quotes - one was for $3,850 to replace motor and ECM and the other company said there was not available replacement available and said I absolutely MUST buy new unit which was $10-12k. I just replaced the motor and ECM with parts from Supply House for $750. However, from your video I figured out that it was the inrush current limiter that had blown and bought new component for $5.07, so will either save as backup or sell used but working on eBay and probably get $200-300 of my money back, I would have sure paid it.
Where did you find the inrush current limiter?
I got myself into the trade watching UA-cam. AC service tech knows their stuff. I started at an apartment complex as a groundskeeper and within two years I was lead tech. Now, I’m in residential working for a really good company that really doesn’t have time to train. Most companies don’t have the resources (especially in todays economy with everything getting so expensive), to send two techs to a house so one can learn. So you either start as a helper making $10/hour where you’ll be on install or you learn the stuff and go in making $30/hour on service. Learn this stuff. You won’t be rich but you’ll make a comfortable living. I’ll be moving into industrial and commercial soon. We do commercial now but I’m looking forward to working on more complicated things like chillers and oil heaters.
Really cool Steve! Thanks for sharing!
Congratulations Shawn on the marriage, I wish you and your wife a lifetime of happiness.
Brother I’ve been following from the beginning and will continue to follow your videos. I enjoy the way you approach content and then share it.
Semper Fi brother!
These are the best HVACR videos around the world from AC Service Tech, congratulatuons from México
Glad you are enjoying the videos Samuel!
Your electrical troubleshooting videos have been helping me on a daily basis, and your book has been a huge help in the field for me to look back on instead of calling my techs. It would be amazing if you made a book on electrical troubleshooting, having a good guid handy really helps out in a jam for a newbie on call lol
Thank you very much for letting me know and I would very much like to in the future, thanks!
Thanks for sharing Craig. I tell all my trainees to watch your videos. It’s amazing what this industry has become with everyone sharing information thanks to people like you putting in the time. Great video sir!! 😎
Thank you so much for the information on this ECM.
I'm a maintenance technician at a retired community and I have ran into some problems with some of my air handler blower with this ecm. So watching this video gives me a little more information on what to look for.
Again thank you for your fine work & information!
If you replace an ECM motor and it is ramping up & down... make sure the blower is turning the right way. Thanks for the video!
Great imformational video. Had an X-13 motor running constantly, without 24v, about a month ago. I replaced the entire motor. I was unaware untill watching this video that you could replace the module only. Your videos are always helpful.
Thanks Eric!
I just started out in this field and luckily I have been lucky enough to work with someone who has 30 + years experience.. But he will make the time to teach you if you’re interested and trying. Not trying to wast time
I live in the Chicago area, lots of supply houses, but on a Saturday night at 100 bucks + an hour the bill can be ridiculous. I've also had supply houses be out of stuck. I always carry a standard PCM motor for older style motors. At -10 outside the people don't want to hear you'll be back tomorrow if you can find the part. So, I will install the PCM motor and hot wire it low for heat and high for AC.to give them service. I know some guys that carry an old working motor just to give service and you can take your time getting the right part. I carry a 1/2 hp. does 1/6 thro 1/2 and 90% of my calls.
Great explanation !! I’ve been in the field for many years and still learn a lot from your videos.
Absolutely, I wish I had all the online training, articles, and videos when I started. I could have learned a lot faster when I started in the trade, thanks!
I have a carrier unit with the broad ocean ecm you have in the video. I have had an issue 3 times now where all of a sudden when the ac turns on the inducer/blower motor doesnt turn on. The first time I got it working, but to be honest not sure what I did is all I did was test just like you said and when I hooked back up it worked like nothing had ever happened. It then did it again several months later. I was out of town but the wife and kids were at home and I just called an hvac tech to come and look at it since I couldn't trouble shoot. I had the wife simply kill power to the whole unit and when the tech got their the next day he flipped the power back on and it worked with no issues. Basically paid him for a trip to come to my house and turn it on. Well now it has been about 6 months since hat time and it has done it again. Of course I am out of town, but I will trouble shoot when I get back.
Sorry for being such long winded but wanted to give you as much info as possible. So you have any idea why it would be intermittently not working. Why would it not work then when turned off for a period of time or when testing it it just all of a sudden works like normal again. I had thought the first times were due to power surges and actually installed a whole house Honeywell surge protector about 3 weeks ago so it wouldn't happen again. This last time, today my wife said there were not any power surges. Any help would be appreciated.
You may have an intermittent problem with that blower motor. That means it’ll work when it wants to and it won’t work when it wants to. That’s a sign of a bad module or blower motor or both.
Thanks!
Thank you so much for your encouragement!!!
I see a lot of ECM motors on Fan powered boxes (VAV's) and this is the best video with explanations I have seen to date. Usually, the factory recommendation is to use the "Tech-Mate" adapter and call it good.
Thanks for the great video.
Thank you all HVAC school members for these great lessons.
Glad you like them!
Great information Greg! Just to add another tidbit of information, I had purchased a generic X13 preprogrammed ECM motor, but the motor ran backwards. There are three stator windings which are very similar to a 3-phase motor. One can cut any two of the three wires on the connector going to the stator windings, reverse the leads and the motor will run in the reverse condition. I don't recommend this, but it will work as I've done it to get a unit to work. Fortunately, the motor speed was very close to the original.
Nice, thanks Stuzman!
Some of those motors have a way to program it to reverse the direction of the motor. Also, the motor is a three phase motor, but that doesn't mean you can hook it up to three phase straight from the breaker panel as a temporary work around. I tried this as a last ditch effort to get the AC blowing again, and the windings started to cook. We were over 80 miles offshore so getting a replacement wasn't going to be quick. Thankfully, the field had a crew boat that was making a run to the beach for resupply the next day.
Excellent vid. IT would be nice to know what application of the 24 VAC motor speed control signal actually do, and how one goes about "programming" which speeds are active. It is clear from your vid that only 1 control signal is to be applied at a time. What if the air handler controller feeds 2 at a time?
I found the same thing… a Goodman system feeds 24v to 1&2 when heating or cooling and 24v to just 1 with call for “G” alone…
This video was fantastic and helped me diagnose some issues I was having with my blower fan. Thanks for putting this together! Very informative and very helpful. Keep up the great work!
This was the most detailed explanation of these motors I have ever seen. Thank you so much!
Glad you enjoyed it!
I was just diagnosing one of the ocean broad motors yesterday, this video was right on time. Kudos
Nice, thanks!
Perfect explanation and understanding of how to service these motors. I have been trying to find something like this for a while now and you nailed it. Thanks man.
Thanks for watching!
Some of the X13 controllers have an OFF Delay (30sec-3min) built in. My ComfortMaker (Carrier) does this. The only way to stop it is replace the control board without the OFF delay.
Excellent explanation Craig ... I wish you were around 40 yrs ago ... Lol ... Happy 2020 ...
Thanks a lot Eddy!
Great video! Too bad most control modules are potted. I do component level repairs on just about everything, so it bothers me when manufactures make things disposable. I liked that you said that the MOV is replaceable. Hopefully some technicians will have good soldering skills and will replace them rather than swapping out the module and/or motor. I have worked on some large 3 phase VFD drives for big commercial air handlers, and most of the time its poor soldering and capacitors. The VFDs that I work on are external, and are not potted. Of course there are no schematics, so it is sometimes a challenge. Keep up the great work. Your book is great - I purchased it about a year or so ago. Thank You.
could a bad mov cause the motor to continuously run or is that likely something else in the module?
Thank you! You're a saint for bringing this secret information to the people! And to clearly explained. The manufacturers and installer/dealers are in cahoots to make it hard for the owners of the appliances to handle their own hardware failures. I don't much like situations where early failures bring profit to someone else, after I shelled out for the equipment. I'm not saying everyone should try this at home, but if you are technically educated, it's nice to have the simple facts so you can take care of issues.
My ECM had magnets detached from the rotor. Cleaned off the junk glue film remaining on the rotor and magnets, and re-affixed them with epoxy, original orientation, spacing. Motor working fine again. Thank GE, Beloit and Junktek or whoever owns this now Genteq for stupid glue application. Even multirotors have the magnets arranges so they cannot be thrown off.
You always do great training videos, but this one is one of my favorites. Unfortunately I have already ran across a OEM replacement motor that was programmed wrong, not for sure if it was the manufacturer or the distributor (lot of distributors are able to program motor with OEM specs). Since the motor was under warranty, the service call was negative profit for labor.
Sorry to hear that and yeah we need to be very well versed with the things we tend to run into. Thanks for letting me know Superior!
Thanks for this. The industry charges huge margins for relatively inexpensive parts from Mexico or even China and then we get charged double that by the less scrupulous service technicians. Here in Canada things are worse as the parts suppliers won't sell to the public. I fixed my furnace blower for $25 (cost of five thermistors plus overnight Fedex from DigiKey) after being quoted $1,500 for a new unit. I wish I could find a tech like the creator of this video but, sad to say, they are few.
Ac company came to fix our unit thought it was the blower assembly, then the board find out the yellow wire to the thermastat had voltage on it all the time. Swapped with another extra wire in the harness everything is good.
He's very nice and very good explain ed I have 6 yes in the field and I've still learned with this man other thing.you are doing well thanks
Awesome, thank you!
Catus Maximus! ...I've got a variable speed blower motor went bad so thanks for the info
Only to add that the “in-rush current limiter” you point to in the electronics module is called a Metal Oxide Varistor - and as you said, can be field replaced with relative ease.
This was an excellent description on how these work. Thank You
I’m about to graduate from HVAC course but my IBM went out and the tech that came out did a resistance test on the module and he said it was at 18 ohms but normal limits should be between 10 and 20 so he said it was starting to fail. He replaced the whole blower with a new one that didn’t come with a module on it. So I’m the future I can check the resistance of the motor itself without dealing with the module although the module is cheaper to replace than a motor.
The best video for troubleshooting the ECM, thank you!
Thanks J. Bian!
Great hands-on, Craig!
Thanks Jack!
Great video on ECM's, I hope you put out more video's on Broad Ocean and Rescue motors (maybe you did already??). I would change your explanation on the motor potentially overheating if there's an airflow restriction because motors draw less current with an obstruction (less work as your not pushing as much air - less work = less amperes). I subscribed, looking forward to watching more technical videos!
Just had a first... Payne furnace, newer unit with a broad ocean ECM that wouldnt run so coil froze up. Found circuit board is only supplying 20V to speed tap. Apply 24 direct from transformer, motor fires right up. Apparently the modules are very sensitive and require the full 24V signal.... gotta come up with a circuit board under warranty now🤦🏼♂️
This was a very helpful video my gosh. Do you happen to have a video showing the step by step to swapping an ECM motor to a PSC motor that you would typically carry on the truck?
awesome video, thank you so much for sharing... would you be more incline to replace just the module or the whole motor on an ECM Genteq , if the motor is constantly running....
Which book you recomend to get more knowledge about furnace & ac unit sir 👌🙏🫵🫶 your videos.
Indeed your are a great master
Good explanation,thx,what would be the case if the motor cycle off and on,this will be the module or the motor,thx
Are you better off changing the whole motor if you find that it is just the control module?
Another great share! Good content from your team always 👏
Glad you think so! Thank you for watching!
Can you show how to replace the capacitors and the inrush current limitator?
My ecm motor went out after a transformer blew up in the neighborhood(caused a power outage). Visually inspecting everything in the module looks fine. How do you know what number is a good number when reading the motor part (for resistance)?
always a great reference tool-thanks my friend
Glad you liked it!
Great informative video. Just had a question. When my ecm is plugged in, it’s hard to turn by hand but when I disconnect the ecm. It moved freely. Does this mean I have a bad ecm or bad blower? Should I just replace both?
Excellent explanation on ECM motors diagonis / test for continuity and ground..
And on module itself!
Great video ,Craig !

So if an X13 is ramping up and down. Is it the control board in the furnace or the control module attached to the motor?
Thanks a lot for this lesson you are awesome and I already have your book but I going to get your quick cards reference,thanks
Awesome to hear Angel! Thanks!
can capacitors on the x13 module be replaced?
I would love to see a similar video done for the GENTEQ 5SBA39GLV5000 EON. I've replaced one module already with a used Ebay find with the motor about 4-5 years ago and am back in the same boat replacing that one. Just trying to limp this old equipment along untill it just isn't worth it anymore.
The reason I would find it interesting is that the low voltage connection on these has 13 wires and a control board with dip switches that a set your CFMs, some ramping profiles and aux heat speed. Last time I replaced the board and the module for good measure, but this time aroung Im pretty sure its the module, as it occasionally starts running and does a sortof "searching" behavior before it just gives up altogether.
I would love to know if there is any common fixable problems with these as I'm about to become the proud owner of two backup modules, motors and one control board.
Where I live these motors are 1000 bucks I have been kicked out of customer house because of price of the part I don't even mark these motors up it's grate to have high efficiency but there is no savings if the savings have been spent on repairs
Thanks Craig! Happy 2020!
Thanks a lot Marcus, you too!
Thanks a lot Marcus, you too!
Can you take amps readings? Also can a continuity test be done on ecm motor connection points or controller connection points? Would manufacturer have the specs on those readings?
Yet another win from AC service tech. Just swapped my module, unfortunately the return air vent was making the motor run harder…time for a louvered door
Good afternoon. I have a Lennox xc17 that is now out of warranty and in need of it's 4th ecm motor. I am considering replacing it with a psc motor and a relay. However, to keep things simple I am also considering the rescue ez13 motor as a replacement. What are your thoughts regarding the ez13 and it's reliability? Also will I still be able to use the Lennox lcd thermostat that came with the xc17 if I switch to the psc? Thank you and any help is appreciated.
I have a Carrier F4BC model and it will not stop running. I have to shut it off at the circuit breaker panel. I pulled the thermostat roo and it keeps running, so I'm thinking it's the circuit board on the motor. Probably a relay???What do you think? Thank's.
Craig I had a need problem brand new furnace motor ramping up cw then stopping then turning cw then the furnace would go out on high limit this indicates a bad motor
How to check module is good or bad without power on? Thks
Thank you for your guidance and explanation , keep it up 👍
I have a question that I hope you might be able to shed some light on. We purchased a new home about 2.5 years ago. AC and heat has run fine for that time frame. Last night I got an alert from Nest that it ran for a longer than normal time and temp did not come down. I was gone all day and discovered the unit was not circulating air. I checked all the common stuff and it was running so I put it back together late at night. Mid day today same thing, no circulation. I pulled cover back off to find the capacitor (did not know there are now ECM's on them and discovered the blower motor ground was just hanging and had never been bolted down. it was just barley touching a bolt, but is it possible for 2.5 years this was operating normally with no ground on the blower motor (or very lightly touching)? I know sometimes it can use other grounding ways, but found it odd. Thank you and I am interested to hear your thoughts.
Did you say that the x13 has to be programed and if it does , who does it? Thanks for the great video.
Good one. Happy new year Craig.
I wish I had a dad like Graig.
Does anyone know the socket size used to remove 2 bolts holding the ECM module to the Genteq X13 motor? My female friend is going to try to do the job herself and want to make sure she has all the tools before starting the job. Thanks
A great video as always. Keep doing what you do best !
Thanks a lot William!
So what is the board called on the broad ocean motor that monitors the rotation/speed?!? So I had a motor on the fritz…swapped with a good ECM module, tested the leads like in your video and the windings tested good…if it was the circular board? What’s it called to try and source it?….(tries to look up parts catalog of numbers)
Great video. Thank you for sharing your knowledge
Thanks a lot Rocko99!
I have an x-13 that will not stop running even without the 24 volt signal wire. I have isolated the issue to the ecm. So I will have to get a certified tech to replace the ECM because it has to be programmed? Is there any way to buy one programmed for a specific system? I don't think the original installers of my system even checked actual air flow
My furnace blower motor has an ECM module that was just replaced.
I still need to help start it by spinning the fan with my hand. Once it is up and running it will stay running. I always just keep my fan on because of this.
Any ideas why it won't start by itself though when I turn on the heat?
First of all your videos are great. I don’t usually subscribe but I felt compelled to do so after watching two of your videos. What is the expected resistance 1/2 Hp 208/230V X13 motor. I’m getting 12.9 ohms on all. Sorry I’m sure you already answered in comments here or elsewhere but I don’t see how to search comments.
I had a X13 module that was only receiving 21 volts from the board so I verified the transformer was on the correct voltage leads and the transformer was only putting out 21 volts. Could that cause the module to not start up? It wants to start but kind of jerks back and forth. I brought it home and going to apply 24-26 volts and 240 volts to it to see if it will run. Or should I just replace it and the transformer?
Interested in this as well. I assume it's close enough but not completely sure. Mine tested @ 22VDC.
They could have made it repairable by any entry level electronics tech without the potting (epoxy resin poured on the board) for $10 worth of parts. We could keep and repair the cores but removing that stuff is almost impossible.
Well done. You are a master!
Thank you very much!
You are the best 👍👍👍
Great job and video like always
I appreciate that
So how does the different speeds work? Does the high speed kick in when it gets hotter outside??
What voltages do you expect to get out of the module and is there a way to connect power to the motor for temporary without the module? Maybe some type of universal module you can pop in there until you get the new part?
beautiful explanation
Thanks for liking
My Climatemaster ECM blower motor makes knocking noise on start up. Does it need replacement in the near future? Or it can be repaired? Thank you!
I have a blue wire plugged in the #3 slot and a white wire in the #4 slot. Why do I have two wires when you have one?
I replaced just the module once and it blew up as soon as power was turned on with no call. I can only assume something may have been wrong with the windings, I didn't check prior to swapping module. I did the walk of shame back to the supply house...lol
I used tech pro and I got the ecm motor running so should I replace the circuit board because it’s not getting 24 volts signal? Plz Craig reply
Can anyone tell me what the FM abbreviation stands for? I deal with a lot of these modules, mostly FM07, FM19, FM20, FM38, and others.
But I can find no reference to the FM abbreviation online. Any help is appreciated
Anyone know about that?

Great video as always would you please do a video on ecm 16 hernes plug thanks
Karim, yes I believe I have done two videos on that. One was how to wire and make your own variable speed testing setup, thanks!
I look for it thanks
Please help. I was checking a X13 blower motor and it was ramping up and ramping down like you showed in the video so we I tolld tje costumer they needed a new blower motor. Well when I was checking the low voltage on the motor I was getting 28 volts on terminal #1 and #5 on the low voltage side at the same time, It only has those two speeds. So is that normal? Am I supposed to get 28 volts on #1 and #5 simultaneously when I check it to commun?
Can you pls do a video on two-stage compressor (working/troubleshooting)
Are multispeed blowers supposed to change speed during operation or just one speed? mine always runs on high, does that mean a problem?
I’m a new “watcher” , but definitely an old guy . 43 years and still getting out there. I recall that supposedly there is one component on the GN 24 ECM module that can be replaced. I would love to prevent my customers from paying $1000 for a new motor and module. I believe it is a IRQ 20 , 141Q Capacitor or resistor. Any suggestions?
My blower motor is running very weak that I can't feel any airflow at the vents but when I reset the unit and power it back on it works at high speed and gives me great airflow but only for 10 minutes or so before it shuts back down to slow speed....
Is this generally a problem with the module/motor or could it potentially be an issue with the control board?
Thank you sir nice explanation👏🏻
So nice of you
Honestly a great video great teaching abilities
👍👍
I appreciate that!
