Great video and tips! My AC compressor fan stopped working so I replaced the start capacitor since it is an inexpensive part and the existing capacitor was over 10 years old and the top was rusty. While I was in there I cleaned up the wires and checked for any damaged wires, but everything looked good. The fan still didn't work. I spun the fan manually with a wooden dowel to make sure it spun freely, and it seemed fine. I depressed the plunger on the ac contactor and the fan started with no problem. I went back to your wonderful library of HVAC videos to find more info about the AC contactor which suggested to watch this video. Glad I did! You mentioned replacing the batteries in the thermostat even though the display is working AND there was no low battery indicator. Sure enough, I replaced the batteries and the AC compressor fan turned on! I've got a better understanding of my HVAC system, I've got a new start capacitor so shouldn't have to worry about it for another decade, I cleaned up the wiring, and I now know that a pair of fresh batteries can make the difference! Thanks for your great how-to videos!
So glad I saw your comment mine did the same thing!
Very similar story. I did change the batteries just to be thorough, but every indication was that the thermostat was working fine. You'd hear a nice crisp snap of the relay and the squirrel cage fan would kick on, but no compressor. Before going into the compressor itself, I decided to swap in a known-good thermostat. Voila, nice dependable AC again. I was picturing a potentially expensive repair, but a $25 thermostat did the trick. So -- just because your thermostat starts the squirrel cage blower, your thermostat can still be the culprit.
I work a for hotel we have over 300 units on property from 2 ton to 7 ton this playlist has saved my boss lots of money and got me a promotion
Same here resort hotel with 100 units!!
My AC repair guy was charging $1200 to fix my issue, after watching this video I ordered a new contactor for $18 on amazon and fixed it myself. Thanks a ton you saved me a lot of money!!! It’s worth noting I’ve never worked on ACs before
This is why nobody trusts HVAC companies. $1200 to replace a $10 part in 15 minutes?
Contactor should have cost you 8$,.
I'm really hoping you see this comment.
I moved into my home 13 years ago. The first thing I had to do was call an HVAC guy out to charge the system because it wasn't cooling. Over the past 13 years I've replaced the A/C capacitor several times, the furnace heat sequencer several times, the thermostat, fatigued and broken wires and last year the fan motor in the A/C. Every other year, sometimes more often, I was having to fix something. At the end of last season my evaporator coil was freezing up so I figured I'd have to have the system charged again this spring. I procrastinated and didn't do it and then it got hot. I thought about it and decided I was tired of working on it and always worrying whether this 35 year old system was going to heat this winter or cool this summer. I decided to replace the whole system. Being retired and living on a fixed income I found the cost to be prohibitive. Fortunately, I've always been a big time DIYer. Plumbing, electrical, building, renovating... there was never a job I wouldn't tackle. I decided to order a new system and install it myself. Doing it myself would save me about $10,000. The equipment arrived on Tuesday and I had it all installed by Thursday. Friday and Saturday were spent trouble shooting trying to make it work. I watched countless videos on UA-cam looking for helpful information. Blurry, shaky, poor audio, poor explanations, no explanations, incomplete explanations and inconsistent explanations. Thirty minute videos spending the first twenty minutes explaining what they are going to explain to me. Suffering through them all hoping to find ten seconds of useful helpful information. Occasionally I found it, but it was never enough. I know most of these people are trying to share and help, but I would certainly not enjoy being trained by any of them. Then I found you. It was your A/C, furnace and thermostat videos that got me over the hump. Clear and concise with simple yet detailed explanations. How to wire this and how to test that. After three weeks of killing heat I am finally cool. The job turned out to be a lot bigger and more difficult than I expected and pushing seventy years old didn't help, but thanks to you I got it done. Thank you for taking the time to share your knowledge and for doing it so well. I don't subscribe to many channels, but you just got added to my short list.
Thank you for all you do, you have saved me from calling a contractor and a whole weeks worth of waiting for him to show up. Again, a big "THANK YOU"Jay.
Thorough video that got my unit up and running for less than $60 bucks and done TODAY with no waiting. With everyone working from home, this was a lifesaver. Kind Thanks, from this Novice
THANK YOU!
You saved me a very expensive service call. My AC wasn't cooling and I followed your instructions. The condenser and compressor would not come on. I found a cut 24v signal wire from the control board to the compressor solenoid. In my case the 24v signal wire cable is routed under the crawl space of the house and comes out at the back of the house to the Condenser/Compressor unit. Well, the cut/broken wire...that bugger, was severed exactly where it came out from under the house. That said, it was difficult to locate because in the first place because I had inspected the cable and found nothing wrong. I was almost at the end of my patience when my mind told me to tug on the cable where it came through the wall to the condenser unit. Well, as soon as I tug on the cable the compressor/fan came on immediately and ran like a charm. I ended up soldering the broken White signal wire. So, just wanna say thanks again for your suggestions. Lesson learned: never give up when you think you're stumped. Just take a break from the task and come back later and give it another try.
Amazing video. I simply replaced my batteries in the thermostat and got my ac unit working. I'm a residential electrician and my immediate first thought was going to find the problem outside, particularly the contactor, but watching the video before I ran outside I saved myself money and time. I had no idea the thermostat had AA batteries, changed those out and now I'm back up and running. Thank you, liked and subscribed
You're a residential electrician and had no idea that thermostats had AA Batteries?
@@jroberts3428 Took the words out of my.....
Absolutely nailed it, Jay. I am one of those people that jumped at the contactor and ordered one, without watching
this video. Turns out when I checked the thermostat wires, had 24 vac, up until they connected with the delay on break timer. At the contactor 24 volt side was getting all kinds of wacky readings.. Ordered new delay timer as well. Thanks to your videos, $31 probably saved me thousands! Props to you! Oh as a side note, also ordered a dual run capacitor as a backup since its been high 80's for over a week her in Fl.
Was your problem the contactor or thermostat wires,
Thank you! You are doing a great service for anyone wanting to get up to speed on how our air conditioning systems work.
Thanks wanted to know if you know any good heating/cooling company foe training beginners looking for goodjurnyman to work under ,carlos from det MI
Your the best channel I’ve found on the content you offer, very simple, but thorough, friendly and no drama! Great 👍 work. Thank you for the time you give of yourself.
Thank you so much for these. I diagnosed a control board issue last fall and today diagnosed a short in the thermostat wire. Your explanations have given me so much confidence.
This video saved my a$$. I went through all 10 steps. After trying everything, I finally went into the attic, found the correct unit (there were two), and opened up the panel with the fan controller, and sure enough just like the video mentions, discovered a shorted fuse! I replaced the fuse, switched the breaker back ON, and the outside fan shortly kicked back on! Dude, thank you so much!!! You saved me a ton of $$$$.
Any update? Fuses don’t just burn out. You have a low voltage problem that’s going to come back.
@@millenialmemoirs It's been 2 months since I replaced the fuse and it's still working (knock on wood).
Dude, great job walking through all of those issues, I learned more in this one video than the last 20 I've relectantly sat through. Thanks!
By far the most educational advice . Strait to the point. Awesome instructor. Eliminates all guesswork.
Thank you so much. A guide for all.
Thank you. Learned a lot. Will troubleshoot my ac over the weekend now.
You are awesome! I am constantly trying to gain understanding of how the AC system works and you just lay it out. I would love to see an overall video from start to finish of the workings of the system including; sensors, switches, wires and what they power and where they go. Keep up the good work for us novice people out there.
Covering alot of equipment parts with sufficient information for quick understanding and preventing expensive tech bills. Thank you!
Good job....My problem was a contractor that was stuck in. After looking at it, it was welded together. Hope it did not hurt the system. It seems to be working fine now. I watched all you videos and they are a big help. You are the best. Thanks...! Al Sautner.
general amintenance for 8 yrs and this video has to be one of the best videos on youtube. listen carefully and take notes and you WILL fix the contactor not pulling
Hey Jay, hope your having a great week! You sound like you are on a show on tv bro, Your very well spoken yet easy to understand. Great job thank you sir! Blessings
Thanks David!
he is very fluent
@@WordofAdviceTV wouldn't it be nice to have a wire diagram for the switch from the disconnect to the relay contacter to the compressor and then the fan ? Nordyne and ( Miller stopped putting the diagram out there ( mobile home central air unit with furnace inside ) what a joke these companies were. , I say were because they changed hands in the last 15 years at least 12 times
Dude! I've fixed a thing or two and already knew I had 24V outside. I was about to head out for a contactor but thought about your video for a few. Realized I couldn't see plunger. Went back out, pulled the cap and there it was, an earwig stuck right in the spring. Thank you!!
Awesome! Glad to hear the video helped! Stay cool! :)
As someone who's currently in an Apprentice program for HVAC, your videos have been so helpful.
You are THE MAN!!!!!!!!!!! I received a $3,700 quote to replace my unit that was "too far beyond repair"......$28 capacitor, then worked through finally figuring out how to use the multi-meter I've had for a decade to find the high pressure switch needed reset after cleaning the coil. Words cannot describe how grateful I am that you are on UA-cam!!!!!!!!!! THANK YOU!!!
I watched several of your videos and thanks to you now have a good grasp on how HVAC systems function. I narrowed down the problem to the contactor coil not getting power or pulling. After checking all of the 10 reasons mentioned in this video and still not getting power to the contactor coil I went back to searching on line and found another video with a much simpler solution. My thermostat has a separate fan switch that can be set to "On" or "Auto". A house guest must have been warm ( I keep it set to 77 deg) and set the switch to On which for some reason stops 24v power from being sent to the contactor even if the system is set to cool. When I switched it to Auto the compressor started up and everything works. I wanted to share that just in case someone else had an issue with warm house guests. BTW, thank you for posting these great videos.
Thanks for the tip on the auto setting preventing 24V from going to contactor. I had the same issue during troubleshooting. These are great well-made videos!
These videos are the best. Thanks so much! I was able to use this to troubleshoot and fix my AC on one of the hottest days when all of the service technicians were booked up. Cheers!
Thanks karl elvis
I am now retired from about 30 years from ac services or residential maintenance and could not have been explained better than that from a hands on perspective
Saves me hundreds of dollars. My condenser unit is not receiving 24v. I always suspected it's the thermostat but I don't want to replace it without knowing why. Your thermostat bypass video saves the day. Thanks!

This is a fantastic video that I come back to every couple of years when I'm troubleshooting AC at home. Thanks a million for making such a useful video!
Truly an incredible video. After watching several different videos on the net I watched 2 of yours and was able to diagnose and solve my problems. THANK YOU SO MUCH.
ThAnks for your advice that is a great help.God bless you.
Had my AC go out over the weekend in the summer in South Ga and was able to troubleshoot and fix the issue with your video. One of the best videos I have seen. Thanks!
Thank you so much, was able to figure out that the condensate pump wasn't wired correctly so the condenser wasn't turning on. 10 out of 10 would recommend, keep up the great work man
You're the PRO ..! and I'd like to say thank you for showing the world some basic things to troubleshoot central AC units. Handyman like myself love to watch your shows..!
Amazing young HVAC professional I have never seen before..
I don't typically comment, but this was a good video. I was troubleshooting the power to my AC unit for the last hour or so. Last year, I had a bad breaker. This year, voltage was good out to the unit, up to the contactor, so I ruled out the breaker. I manually engaged the contactor while my blower motor was running and the thermostat was calling for cooling and the AC unit kicked on. Led me to believe my contactor was bad. I watched your video to see if I missed some wires to test, because we all forgot stuff. Also, to me, the contactor doesn't seem like a part that just goes bad all that often. You mentioned the low voltage not having enough power to engage the contactor and to swap batteries. I recalled, my low voltage reading was 11v and that is too low. The light bulb kicked on, I swapped my batteries, and now my house is nice and cool. Thanks man!
Thank you buddy.. I am a plumber by trade and knew nothing about hvac until watching a few of your videos. My outdoor ac unit fan was not spinning when thermostat turned on. Actually wound up being the 5amp fuse on the control board at furnace under home
After watching this video, I got my AC back running. Thank you
This channel is awesome for learning how to troubleshoot.
Dude! You rock! I watched the start of your video where yoy said the contactor might not be broken. So I started watching this and suddenly remembered I had switched off the AC at the thermostat so I could run the fan. Turned it to AC and the contactor popped In and the new motor is running flawlessly!!! House feels cooler already, and it is 101 degrees today in San Antonio. THANK YOU SO MUCH! ❤️
Jay, thank you man!!! Just saved me a boat load of money!!
The simple solution after troubleshooting, was to drain the condensation pan, which had triggered the overflow switch
Thank you!!
That's great!! Good to hear stuff like that, thanks for coming back to leave a comment! Stay cool ;)
You are by far the best source of info I've came across. You should teach people, very easy to understand. You helped me diagnose an issue with my jumper between RH and RC on a Honey well zone board. The factory jumper was smaller gauge than the 8/18 wire i was using and causing intermittent contact. Pulled out OE jumper and made one with wire, fits tight and works as it should. Thank you.
You just saved me $1000, your HVAC videos are the BEST on the internet, you Sir, are a ROCKSTAR!
The contactor switch was not pulling in, and before I replaced the contactor, I decided to watch this video. I glad I did because number 8 was the problem! The high pressure switch tripped and I just needed to reset it by pushing the red button. Now I just need to figure out why it tripped. But this guy makes the best vids on AC that I have seen!
Jay: You are one of a kind not many tech go into details like you do thanks for AC advise.
Great job!!! excellent explanation. Very professional tech you are. Thanks for doing this.
Very informative, helpful for maintenance and troubleshooting. Much appreciated.
Excellent video!! Very thorough on the explanation of what signals cause the contactor to engage and what can cause it Not to engage. One other thing that can potentially cause it not to engage and this falls under 'Bad Wiring'-- if the wiring (or connectors) are corroded or partially broken such that it can't carry enough current to magnetize the coil enough to pull the plunger. You could still read 24-27V on the line but it may not be able to carry enough current because it's compromised. I ran into this personally last week. 😝
Mark I seen that exact situation, contactor works when connected straight to the 24v transformer and signal line reads 24v outside at the contactor but contactor still does not pull in
Great videos! Excel here in MN recently replaced a board in my Saver Switch. The tech that did it somehow failed to install it correctly. Tec from Centerpoint comes out and could not figure out what was going on (thank you Home Service Plus) and suggested that the control wire was bad. I ran a new control wire, old one was pieced together so I figured time to replace anyway. Still no control voltage. Scratching head looking at the unit and decided to take the Saver Switch out of circuit and contactor pulled in. Called Excel to let them know and they sent a tech out on Monday who fixed the bad install on the Saver Switch. Your videos helped be out a great deal on this problem. A lot of great info and I didn't have to suffer through the heat on the weekend!
Sorry to hear about the saver switch problems! Glad you were able to figure it out though! Stay cool :)
I see this is 2 years old..but these saver switches are just like what energyStar devices do!?! I think??? Allows either the power CV company or some other company to control the electrical usage!! Tell me how energyStar device that runs for 2 to 3 times longer than a similar device...is better or uses less power??? 🤯🤯🤯 where are my manners.. Thanks for the video!!!
Outstanding video. You have a knack for explaining at a pace which makes your videos very watchable and informative. Keep up the good work.
Thanks for the AC tutorial. Was able to diagnose my problem to a bad thermostat wire. Mouse must have gotten to it over the winter. You saved me time and money. Thanks again.
Thank you so much.. You saved me big money on an AC tech visit. I replaced the compressor's capacitor, contactor, fan motor, AND the air exchanger's control board and transformer--none of it was solving the problem. Then I found this video. I was getting 30 V to the compressor, so as you said, the problem was at the compressor, and it ended up being the High Pressure Switch. Pushed that baby in and we're golden! At least I got some upgraded parts out of the whole affair, and I know a whole lot more about AC systems and electricity.
Thanks Jay. My Carrier shut down during 95 plus heat--I thought the capacitor was shot. But after opening the panel I found the Contactor wasn't pulling in. After watching your UA-cam show I checked the indoor blower in the attick and YES--too much water in the condenser pan; the safety float was up, shutting down the outdoor unit (just as you said it would) Naturally I took credit and my wife thinks i'm a genius.
Thanks a ton for the multiple videos on detecting issues with the ac. I was able to go from not knowing a thing to understanding the wiring for my HVAC, furnace, thermostat and the ac outside unit. My nest thermostat showed error E103, with over current on Y1 wire. I ended up replacing the contactor. And, everything is working great so far. One difference in my observation is that I observed 0 volts between the contacts that activate the contactor instead of 24V as suggested by you. I went around checking everything inside the house, before deciding to try and change the contactor. I checked on raw wire by removing the wire nuts as well as on the contactor fins. Nevertheless I learnt a lot, so many thanks!!
Thank you so much for easy teaching those "10 Reasons Why AC Contactor Not Pulling In".
You're welcome! Thanks for watching!
Thank you! after checking everything I tried pressing the High Pressure switch reset button and that clicked! I turned the power back on and after a while noticed that my AC Unit was back up and running! It's been storming on and off here in MN, so I'll need to go out and give the Coils a good spraying when it's clear out. Thanks for saving me from having to call it in!
Jay, you are the man! Thank you so much for all your videos. You saved me numerous times. Saving me both time and money. I had no idea that the float switch would affect the condenser.
I just got a quote of 5600 because i needed a new unit... It was the low/ high capacitor switch. I cannot thank you enough!
That was the most helpful video I can across the actually help me to fix my
Thank you. I was changing a thermostat and must have shorted a couple of wires. When i put the new thermostat on I got a blank screen. Fearing the worst i jumped into troubleshooting the outside unit. After watching A/C contactor not pulling 10 reasons why, i decided to check the fuse in the indoor unit. You saved me a lot of money. Not to mention this is my sister's business and Friday morning is her busiest day. Hopefully more diyers will run across your channel
I live in Tucson AZ. My dog chewed low voltage wires. Spliced everything back no air. Would have never checked the fuse on unit had it not been for this video. Its 106 outside and I'm nice and cool now. My wife and kids don't have to stay at a hotel and I didn't have to call a service person. Thanks so much.
I'm happy to hear that! :) Thank you for coming back to leave a comment, stay cool!
Brand new tech in Vegas and I just wanted to say thanks for the content you are really helping me get laced up with dextamental information! You helped me get through school as well.
Thank you so much !!!! This is the most informative AC video I've ever seen. Your comment about a weed wacker getting to the 24V coil switch is exactly what happened! I didn't even finish watching the video because it was a quick check and you saved me a bunch of money!! Thanks so much! Liked and subscribed!
Word of Advice TV is an awesome channel!
Hey bro! Love the knowledge & the breakdown simplified
Its always something we think we cant or shouldnt do but you named a few here that i didnt check.
Your channel is one of the best ones on UA-cam. Thank you so much for sharing your knowledge! I just bought my house and the AC wasn't working, not sure how it got by the inspector? But it did, but with your help I was able to pinpoint the problem. It was a broken low voltage wire for the contactor. Thanks again, you're the best brother😎😎
You're welcome! Thank you for commenting, glad to hear you were able to track down the problem! Stay cool ;)
I'm in school for HVACR and your videos really help me fill in the blanks. In fact this video helped me diagnose one of the units at school where the compressor wasn't coming on. It was a bad coil in the contactor. Other people tried all kind of things but I was the one who got the diagnosis right. Thank a bunch.
I enjoy your video's ! Your not sluggish with your presentation , your quick and to the point , Awesome. Thank You !
Thanks Mark! Glad you like the videos! Thank you for commenting!
Props bro. Subscribed. You saved me from destroying my Sheetrock by suggesting the condensate overflow switch was the problem. I had jumpered the contactor to keep the house cooled (Atlanta, August). When I finally checked the attic Unit, water was up to the rim of the catch pan. Some chlorox in the drain line cleared a pint of snot. Now we are cooling fine and condensate is draining.
Glad to hear you were able to find the problem and get it fixed! Without destroying any walls :) Thank you for subscribing and coming back to leave a comment. Stay cool!
Awesome advise you helped me troubleshoot and fix my AC. I never knew there was a fuse on the FAU side! Thanks!!
Great work, great attitude, great presentation, greato human being, great presentation, great personality, great information, Thank you, Thank you and thank you!
Thank you. Great video. Your troubleshooting process led me to the root cause. The symptom on my HVAC was that it would run for approximately 10 seconds then turn off. The drain pan in the attic was dry; however, the condensate float switch had water when I removed it. Re-installing it as is restored service. I will monitor the performance of the system. I have ordered a new condensate float switch (Safe-T-Switch SS2) from amazon just in case. The next troubleshooting step will be to unclog the drain pipe if the switch trips again.
Thank you #4, I had bad thermostat wiring outside my house. Bought a tester and fixed it with your help so thank you very much.
you are a God of youtube DIY videos... thank you and may God bless you. i stoped on # 2 of this video. the water limit switch wasnot triggered by water but by builded up rust from the water that collected and evaporated....thus leaving rust and calcium build up that triggered the water limit switch in the drip pan. people check all the minor stuff befre you spend $200 on a service call. thanks again brah!!!!
mine started working after replacing the thermostat battery. Excellent info in this video!
Thank you very much for your video’s. This one helped me diagnose a wiring problem. I ran new 50 ft control wire from the air handler to the heat pump. My unit is back up and running good.
Why would anyone dislike this video? It is just giving advices on things to check if contactor is not working. Maybe people push dislike instead of like as a mistake while driving their van? 😂👍🏼🍺 Maybe AC company owners don't like this kind of knowledge to be shared to the public? Or even some techs? i have 5 years working on this field and sometimes i watch this kind of videos mostly for entertainment but from time to time i see some good advice. Anyways, keep up the good videos 👍🏼👍🏼🍺
Thank you for commenting! Glad to hear you liked the video! Stay cool ;)
Loved the video and all the explanations. Great tip on the Ants in the contactor. Just fixed my friends AC. Took the contactor apart, cleaned out the ants, put it back together and everything worked.
Thanks SO much. I immediately subscribed to your channel. My contactor quit because the lawn service cut the wires from the house to the condensor unit. Weed wackers are evil!
You aren't the only one :) I've seen quite a few "wacked" wires! Thanks for watching and subscribing! Stay cool!
This video series is great! Thank you for creating it. It looks like I'm gonna have to get in to the guts of my mother in law's condenser tomorrow. Lucky for me I caught the wasps while they were just beginning their nest in the condenser disconnect.
Hope the videos will help! Good luck man!
Best presentation of useful easy to understand advice on HVAC issues. Mahalo Jay
Thank you so much for such a well-detailed video! I'm trying to learn how to fix a lot of things myself. Last year in March our AC got into a sick state after a power surge. That usual "it's off and fan is auto but the unit outside is running constantly and won't turn off" thing. The service guy was very kind to explain things to me, so I at least understood how to cut power to the unit and that the thermostat can be one of several causes. In my case, the contactor was stuck and he replaced it. Here I am not even a year later and same issue. Hoping to fix it myself this time. I'm suspicious it's the contactor again, but I feel like it shouldn't be going out so soon, especially considering the unit wasn't used most of the winter.
I hope you can fix it yourself this time , buddy . Everybody knows there is no better feeling . And this video is a GREAT HELP !!!! I live in BATON ROUGE , LOUISIANA , and I could not tell you how many times we had to replace the CONTACTOR , because ants got in between the contacts or points and shorted it out .... just like he said in the video . That stuff gets very very expensive ... APPARENTLY ANTS ARE ATTRACTED TO ELECTRICITY and the contacts area ... it sounds funny , but when she is up and running again , consider trying to block off ant , etc from coming into the area of the CONTACTOR... sticky tape or paste or something to block their access ... in my particular case I could actually see how they got there !!!! 🌅🌅
Thank you so much for that video! I usually do things myself, last year was contactor and capacitor. Old unit (30 years old) but the compressor has always sounded so good and cools great. I don't want new junk. Went out again today and of course someone came out and wanted to replace everything. Found tripped high pressure switch due to fan being bad. You rock!
Yes..they just want to replace the whole unit...or all the major components!!! That's usually a POORLY trained person!!! They can't really find the real problem!! With the GREAT HEAT WAVE of 2021!!! This is insane!!!
Very details to explain why! I learned a lot and saved money!
Incredible videos that are informational and to the point. Thank you!
Glad to hear that! Thank you for watching and commenting!
What's up youngster once again great job on the videos, you've helped me fixed my A/C, both replace the blower motor and troubleshoot the capacitors. Thank you big man it is much appreciated.
Thanks
Replaced outside capacitor for s&g when my blower motor was actually bad. Then outside unit stoped working. Thought I messed up the simple install
Found the plunger not going in and followed this video
Discovered I broke the common wire on the inside control board when removing the motor. Repair complete! Thanks
Useful info... thanks bro, from Fiji...
My man nailed it. Drain clogged and low thermostat batteries. Thank you so much!!
Between this and your other video I found my problem and learned a lot more about how to check in the future. #2 was my issue, overflow tripped.
Thank you, your videos sure help me diagnose and fix my units...
very good review of the circuit , and well done..
I liked the video and very good information. Great job, thank you!
Excellent presentation covering a lot of territory. I will apologize in advance if you covered my comments in subsequent or prior videos. I would add that cleaning the contacts on the relay periodically might save the homeowner a service call. An HVAC technician noted my relay contacts arcing, while servicing an unrelated issue, and he wanted to sell me a new relay. All relays arc somewhat, because it is switching 240 VAC off and on. However, they get dirty, like everything else inside the outdoor condenser. After pulling the main fuse and/or killing power at the breaker in the service panel, I spray Electrical Contact Cleaner all over the relay, particularly on the actual contacts that typically arc when cycling on and off. In addition, if the system is near the end of its typical lifespan, I will use a small piece of 400 grit wet or dry sandpaper on the contacts - very lightly, to remove carbon buildup. The downside to this practice is the contacts are probably silver coated to enhance conductivity and slow corrosion. Thus, I use as fine of wet or dry sandpaper as I have on hand, and lightly clean all surfaces of the contacts to remove carbon and other residue. The relay is an inexpensive item, so I will probably buy a spare to keep on hand since I have been cleaning my relay contacts for several years. The large can-shaped capacitor is another component that would be worth keeping a spare on hand, because they all eventually die. Use your cell phone camera to have a clear record of what color wire goes to each terminal. As the condenser fins collect dirt, grass clippings, and cottonwood fluff, the fan has to work much harder to pull air out of the top of the condenser. That usually leads to the capacitor failing, and often the capacitor is operating both the compressor and the fan. That is the main reason to routinely clean the condenser fins a couple of times per season - rinsing from the inside out. Always kill power by removing the outdoor fuse or breaker, and/or at the service panel. I got in a hurry once, thinking I was only going to rinse the fins and could easily avoid the high voltage area, trying to finish before dark. I was a licensed electrician in the 1970s, so I knew better. Water hit the two insulated legs of 240 volts, and Kapow! Two-hundred-forty volts explodes. There were two previous nicks in the insulation of the #8 wire from years of rubbing against the louvered exterior cabinet, that shorted when water hit the wires. Several HVAC technicians missed the nicked insulation during previous service. No harm other than my ego. At least I now knew those #8 supply wires needed to be replaced. The installer should have zip-tied the wires away from the louvered grill of the exterior cabinet, but there is never any excuse to clean fins or perform any service while wires are hot.
A WEALTH OF INFORMATION ... THANKS A BUNCH !!!! SPARE CONTACTOR , CAPACITOR , AND CLEANING THE COILS !!!! 🌅🌅
Good job, very detailed step by step explanations
I went to Lincoln tech for HVAC an 11 months course and I learned more from you! Lol.. seriously
You're the best youtuber in this field.
Please help me. Lol
My ac wouldn't turn on, but my blower inside is working. When I push the plunger in, it turns on, but when I let go, it shuts off. I replaced the capacitor, and now my ac is short cycling. On for about 10 seconds, then off. On, off, etc.
If you still have gas in it and no leaks I’d ohm out the compressor
Jay, thank you for the video. I was trouble shooting my Trane and went through your steps. Turned out to be faulty thermostat wires at the contactor.
A/C nice and cold again.
Awesome! Glad to hear you got it fixed! Thank you for commenting!
Good tips! Woke up to no power in the house (which came back on shortly later), 58F indoor temps. Checked the thermostat and it clicked, but nothing happened with the heat pump. After checking the voltage on the outside unit, I thought about you saying that the fan should blow and ours wasn't. I thought it might be the condensate line being full, but it was empty. Then I moved on to the disconnect fuse for the air handler and turns out one of the 60A 250V fuses were blown. The emergency heat has been working overtime and I think it finally took the old fuse out. $16 later I'm back in business. I'll make sure to give the unit a break. It's been unseasonably cold with the arctic blast of Christmas 2022!
Dude, thankyou! Superb explanations!
Very knowledgeable bro.mostly more b.s and one tracked mind a-c mechanics.. Dispatch to rip off and change parts for no reason.. But you know what you talking about.. Very good. God bless you bro. You are honest.
