I so badly hope you read this!! I'm a single mom with 4 children, it was such a bad week and to top it off the furnace wouldn't get hot!! I checked the door, watched the light blink, then watched YOUR VIDEO and cleaned a possibly clog port (and yes gently blew into the little hose to check the switch without damaging the diaphragm) and SUCCESS!!!! I'll be honest I she'd a couple proud tears. Thank you thank you thank you. Not only did I solve the issue, you taught me so much about my furnace and that's invaluable.
I did see this comment! 🙂 I'm very happy for you!! Glad to hear the video helped you find and fix the problem! Stay warm and God bless you and your kiddos! 🙏🙏
thats awesome and yes. this dude is awesome....always always check youtube on videos first before calling a tech (watch multiple videos on same subject to get the best understanding of it)...you can at least rule some stuff out or confirm certian things are cracked, broken etc...
@@WordofAdviceTV Same tears I shed like Amanda Davies☝😭. Thank you so very much for your video. I saved money that i didn't have. I Lost my job and having to sell my house asap. Thermostat message read "low pressure switch open when heating" . I was wondering why i felt cold while painting 14.5C 🤦♀️. I exercised your advice and all is well now. Thank you so very much. Merry Christmas and God Bless you and yours sir!🙏
Same issue here. It’s 1 AM and I have a 3 year old and an 8 month old in the house. It was steadily getting colder and in 20 minutes I was back up and running. Thanks a million! Couldn’t imagine paying that weekend service bill so close to Christmas. Merry Christmas and thanks again!
You are not a victim
Very helpful, and I appreciate you giving the homeowner a chance to fix their furnace, even temporarily, when it's 30 below outside in the middle of the night when you can't get a repairman!
You just saved me like $700+ and a freezing weekend and potential damages. Boom.
Again this is the best video ever. Jay you make the best videos. You saved me before a few years ago. I don’t understand why your work is so under the radar. Bless you

Man, that was thorough, simple, and concise! Really well done. I am an hvac service tech and this is as good as it gets imo. Nice job!
You are the man! You explained all the possible causes extremely well. It turned out that there was a wasp nest at the end of exhaust pipe outside the house. Cleared it out, and the heat is back to work perfectly. Thanks!
You are the best! Thank you for taking your time to educate the rest of us in such a clear manner. I am a 66-year-old widow and was able to clear a plugged pressure switch port. I had to try clearing it twice, but then it fired up. I found a small nail was able to break through the clog better than a wire. Thanks again.
Incredible guide and step by step instructions for fixing a pressure switch issue! I was able to fix my Goodman furnace that had a pressure switch fault code using the steps outlined in the video. I have a high efficiency furnace and my issue was with a plugged condensate trap. It was very much clogged with water spilling out so I removed the hoses and flushed out the ports and boom everything was fixed! Jay, you are awesome my man! I just subscribed and will be telling everyone I know about your great do-it-yourself videos! Thank you so much!
Incredible video. This helped me resolve my error 31 code without having to call a technician to come out and service the furnace. Thank you very much for both helping me develop a better understand of how a furnace works and also for providing me with information on how to trouble shoot the error 31 code.
Fantastic. This young man will be very successful. He knows his stuff, communicates exceptionally clearly, excellent personality. All the best in your career!👍
He won’t be successful because he makes diy videos so everyone will fix their own furnace and he won’t go on service calls…😂
@@Slavelife9279Yea I thought about that too.😂
Then again a lot of people are more lazy nowadays.
You have, in a span of 2 weeks, helped me fix both my dryer and my furnace. Thank you for making these videos! You explain things so well!
and my wife has been very appreciative! 😉 Thank you sir!!
Absolutely the best diagnostic video!!! It ended up being a plugged pressure switch port. Cleaned it out with a piece of wire and works like a champ! So grateful to have come across your video. Thank you!!!
You have the gift of explaining complex matters extremely well! I have a Bryant two-stage furnace, about 10 years old. It's been giving the 4:3 pressure switch code intermittently since last spring. I went though the troubles of replacing the control board, and later the pressure switch itself. None worked. This weekend the overnight lows are going to be in the 20s so I must have consistent heating. Before I bite the bullet and call the plumber, I decided to do one more UA-cam search on the issue.... Boy oh boy! It was the pugged condensate trap! You even pointed out the brands of furnaces that are prone to the problem. Bryant is one of them. Thanks so much and cheers!
Jay - thank you so much for sharing your knowledge. I had searched and realized I was dealing with a code 31 on my Carrier Weathermaker 9200. Once I knew where to focus my attention, I continued to search and found your video. Once I viewed it, I was almost certain it would be a clogged P trap. It was very clogged. It is now cleared out and everything is working as it should. You saved us a lot of money, since we didn't need someone to come out and address the issue. We're renovating a house we completely gutted and are in the process of putting back together, so saving what would likely have been at least $300 for a service call is greatly appreciated. Your videos are straightforward, concise, and you have the perfect voice and demeanor. Keep doing what you're doing!
You are seriously one of the most informative sources on youtube. You covered every possible scenario that could be wrong with my furnace. I believe it's a blocked intake since removing the cover allows the furnace to operate normally. I will pass this link along to everyone and recommend they use it as a reference before calling for expensive service.
Thanks!!!
I so much wish he would diagnose my furnace !!
Hands down, the best video explanation for furnace repair. I own an IT business, so I think I can fix anything. ;-) With videos like yours, I usually can and save a ton of money in the process! I thought I had a bad pressure switch and ordered a replacement but ended up being a clogged port. It's a Bryant with the port behind the inducer motor assembly and a pain to reach but I managed and it worked. Fixed it at 4AM. The family was relieved. Subscribed! Thank you!
Just wanted to say thank you!!! The step by step troubleshooting in this video is great. It was super informative but also easy to understand. TWO thumbs up to you!!
This video is 100% responsible for my resulting troubleshoot & fix of my furnace. Condensate drain line was clogged, causing water to backup into the secondary exchanger/inducer chamber, which blocked the necessary suction needed to close my pressure switch. 👍
I owe you a case of beer, my man!
I have watched a bunch of your videos , they are amazing . You have a natural gift for explaining things . I have just cleaned my burners taking especial care with the thin flame channel and the flame sensor . My furnace is different I had to remove the burner box ( the burners were held in place by screws ) . I replaced the single pressure sensor some time ago . It had failed ( the furnace is about 9 years old ) . I was naughty , I somehow managed to bypass the pressure switch for a couple of days only during the day , until a new sensor arrived . It was midwinter in Canada . I also have a component that I haven't heard you mention so far . There is a "J" tube that the condensate runs through before going to the drain . Having seen this video I am thinking of removing the inducer motor and checking the condition of those fins . A great big thank you for magically making complex things simple .
Thank you Jay, You sir are an excellent technician/teacher.
Great video, once I found the LED indicator light (blinking 6 X's= pressure switch) I followed the steps outlined. I first tested the pressure switch as you instructed, it passed. Then I found the clogged pressure hose fitting, and cleared it, and decided to check and clear the exhaust pipe ( it had some wasp nest and carcasses). Re-installed, furnace fired right up. Thanks so much!
What a great tutorial! I new from the code that the pressure switch was stuck open but had no idea what it looked like. I followed his advice and now my furnace is working again.
It's the first time getting cold this season - after hours and I was losing my mind trying to figure out what was wrong with my furnace. Your videos are a total blessing. Thank you!
Excellent video. The level of detail and delivery are superb. Thanks so much.
You saved my Bacon! After almost giving up and calling in a pro, I watched your video and it led me to the pressure switch, which led me to the blocked vent switch. Reset the thing and now I have heat. Your videos are the best on the web for being easy to understand. Thanks!!
Happy to hear you got it going! Thank you and stay warm! :)
This video has been among the most valuable I've encountered in my many years of surfing "UA-cam University." I have a Bryant furnace and it's been shutting down during a cold snap. I was getting the 3-1 code (pressure switch) and was just about to go out and buy a new one. I figured that had to be the problem, but watched this video just for the heck of it.
Sure enough, I pulled one of the hoses to the trap and about 1/2 gallon of water came out of it. Thanks for the tip of having a bucket nearby! I would never have thought there was that much water in that hose.
I pulled the trap out and sure enough, it was really clogged! One input hole in particular was very clogged and would allow water through it, so I used a small snake made for unclogging evaporative cooler lines and gently ran it through that hole. That finally got the water flowing and black sludge kept coming out. It took about 20 minutes in the sink to get the water clear and for it to flow freely out of all the holes. Just to deep clean it, I have the trap soaking in vinegar as I type this. I'll give it a final flush and reinstall. Thank you very much for this video!
OMG!!!! write after I read your comment, I tried that too, and guess what happen. Same crap for my case!! Thank for the answer Ricotinez and of course JAY!!!
I have worked on the technical side of the automotive business my whole life. The competency level in that field varies dramatically. I have seen the same in many other trades. After watching a couple of your videos, I would conclude that you are among the top in your field. My Carrier furnace was flashing code 31, related to the pressure switch. My root cause was not one of the one's you or anyone else covered. Of the videos I watched, only yours provided the detailed design and function information that allowed me to fault trace a piece of equipment that I am not familiar with. I had 28 volts going to the pressure switch. When the unit powered up and the fan came on, I then had 28V on the switch output. I initially though that the switch closed due to excessive pressure. Armed with the knowledge I got from one of your other videos, I could conclude that the switch was ok and the pressure that the switch was monitoring was ok. That left the possibilities of the 28V signal not reaching the circuit board or a faulty circuit board. I followed the orange wire from the pressure switch and used the wiring diagram attached to the unit. It turns out my unit has an optional device called "auxiliary limit switch, overtemp, - manual reset". I had 28V going in and no voltage coming out. There was a small yellow button on it. I pressed it, it reset, and I my problem is resolved. I think it is great that you and others take the time to post informative videos to help others solve their issues and save a lot of money. Your videos are some of the best I have watched. Thanks,
Jay, I've watched several of your videos and you've saved me a lot. My furnace would reset and come back on 30 minutes after cycling power. After checking many things, I finally pulled the intake pipe and discovered leaves and bits of leaves at the grate just above the burner box. I would have never suspected that since the intake is fairly well covered up outside. Good troubleshooting advice..and good perspective on potential problems. Well delivered as well! Many thanks! 👍
Thank you many times over. Our gas furnace was not coming on. I watched several of your videos on how furnaces operate and how to troubleshoot and narrow down issues. I then went straight to looking for an error code on the controller board; then watched this video once I got to the pressure sensor switch open code. After probing for proper voltages, I blew into the pressure sensor hose going into the fan/motor housing, and it was completely stopped up - no air movement. Ran a wire through the port, plugged the hose back in, and the furnace was back to working. Your hands on demonstrations and practical tips - like shorting out R and W to call for the heater to turn on - are very helpful.
You, Sir, are THE MAN! I checked the exhaust and could see no obstructions. I checked the wires to the pressure switch and they were connected solidly. I pulled the hose from the pressure switch port and gently blew (no effect) and then sucked on the hose and heard a "click". My next move was to unravel a paperclip, wipe it thoroughly, and insert it into the pressure switch port. I felt some resistance in some areas so I ran it in a number of times focussing on the sides of the tube. I reconnected the hose and 2 minutes later the blower came on and I saw (for the first time in a day) a flame and then the burner lit! AMAZING. They wanted $185 to come last night - I told them I'd wait until Monday and pay $65 (and I have a service agreement! ). The house is warming up again and I'm cancelling the service call. THANK YOU! You are truly THE MAN!
it seems like every winter I have to come back and watch your videos!! You have saved my life 2 times now!! thank you!
Thank you so much!!! I was prepared to pay hundreds of dollars for a service call, thank God they didn't call back, watched your video I fixed it in less than 10 minutes. Your the GOAT.
Jay, thank you for the accurate and useful information to understand and help repair a furnace issue. This Sunday morning, I noticed our 12 year old High Efficiency Carier furnace making a running sound. Our thermostat showed 66 (set at 68). The main furnace blower was not running. I removed the furnace panel and didn't see flashing error indicators. However, I didn't get down on the floor to look into the little observation hole. So, I started looking at the many hoses and connections and discovered the condensate drain hose, severely bent. I can't believe it was built this way, but maybe through the years the strength of the hose weakened and could no longer support the sharp radius bend. I went out to my local auto parts store and bought a foot of rubber hose to replace the old one.
Thanks for the tip about cleaning the condensate trap. I removed mine and used an old drain cleaning snake (like a large pipe cleaner, that worked great). There was not a way to attach the photo of the hose and cleaning snake, so I added that as my picture for reference.
Thanks again from a past TV repair guy (with BSEE)

I want to thank you so very much! 2 days ago we spent nearly $400.00 for a company to come out and replace a $20.00 transformer. Guess what the heater stopped working today. I truly want to thank you for being unselfish and helping me and others right now in need because of the virus and inconsistent work. You saved me probably $100s of dollars not to mention getting my wife off my back about freezing....LOL! Thank you again. Kevin Mc Millan
I have to honestly say that you are the best in explaining everything. You should be teaching at a HVAC school! I can watch your videos all day. Thank you for posting your videos and please keep them coming!!!
Thank you. This video and one detailing how to remove the condensation trap have enabled me to get my furnace running again in the middle of a snowstorm on the coldest day of the year. Huge relief!
Thanks Jay. This was a great educational video. For me it was the inducer motor not wanting to start, it was humming and maybe having 1 revolution in 20 seconds. Took off the motor, spun it by hand and blew it clean with compressed air. It started up immediately when plugged in. Reassembled everything and the furnace works great again. Great and cheap fix when it is -29°C outside. Calgary Alberta, Canada
OMG ... you are very, very good. You deserve all the positive comments in this thread. Well done young man. You will make a difference in this world.
Jay is the best in the West and the whole U.S. He explains things SO WELL AND SO THOROUGH. He's the best instructor I've seen in my 75 years.
Hahaha Thanks Mr. Konesky! All I know I learned from my seniors, my wife does a great job of filming me and the video editing makes it seem like I am better than I really am. But I still appreciate the compliment! :)
Agreed I was thinking the same thing this guy has skills. Thanks for taking the time to do this. There’s a special place in heaven for people like this!
Thank you again for saving me $ on a service call! Came home to a cold house. My system was flashing "pressure switch stuck open." Watched this video and checked the pressure switch port on the inducer by unhooking the tube from the pressure switch and trying to blow/suck through it. No air was going through. Ran a wire through it to unplug it. Now working! Thank you thank you thank you!
My husband and I are so happy to have seen your videos and learned so much about our furnace and fixed by cleaning out hoses cut off the cracked tip and clean out the little plugged up pipe. Thank you for your informative videos.
Currently an apprentice in the HVAC field and your channel has by far built me into a better technician I appreciate it. One tip though, doing a brief breakdown of everything you went over in the video at the end would be great. Thank man
this is the second time your videos help me fix my broken furnace. i truly appreciate it. your videos are awesome! you should be teaching a class if you aren't already.
I can’t thank you enough for this video.
I replaced just about every part in my fiancé’s 23 year old Amana/Goodman 90% heater, but it still wasn’t working
and the cause was a pressure switch- which I had already replaced.
I replaced the induction motor a couple of days ago and I tested the system. It ran for 37 minutes and 28 seconds then cut out.
The blink coach indicated the pressure switch - - i.e one of the ones I had just replaced.
I was about to call a repair person when I watched your video.
After I saw the part about the condensation,
I said I’ll give it one more try. I pulled One end of the hose hose off the pressure switch and pointed it down outside the heater. About an ounce of water came out.
I pulled the hose off, blew it out with Canned air let it sit for a while on the sun to dry it out. I reinstall the hose, crossed my fingers, and fired the unit up.
And it did fire up and is running perfectly.
The thermostat was satisfied in the unit shut down, but I am running the circulation fan only for about six or seven hours to make sure that all condensate is out of the unit.
Thank you so much for your brilliant video.
I have an old system that has no codes. There was a crazy wind storm last night with 60+ mph gusts of wind and my furnace would make noise but not heat. After watching the sequence video and this video, I tried blowing into the pressure switch hose while it was connected to the blower motor. It was plugged. As mentioned in the video, i poked it with a wire and there you go. This video just saved me a bunch of money and time. Fixed my system with my multimeter, a scrap piece of wire, and most importantly the experience shared by the person who made this video. I sent a donation via paypal to say thank you.
Great video, once I found the LED indicator light (blinking 3 X's= pressure switch) I followed the steps outlined, found the hose damaged, cut off he damaged part, re-installed, LED light solid red, furnace fired right up. Thanks so much!
I've been troubleshooting many other things both for work and at home my whole life and immediately knew that this was going to be extremely helpful. You covered a lot of ground in a very short time. I was not disappointed! For me the pressure switch would not release until I removed the tube on the condensate side. I'm pretty sure I'm going to find that it's time to replace my 30 year old furnace. The good news is that I was able to get the heat running for now, the inside temperature was getting pretty low. I need to poke around some more to see what I can find but I'm pretty sure I will need to call in the professional's for a total replacement. Unfortunately, from experience I know that it will be best to checkup on the work they do, they all are not as good as you are. For instance while troubleshooting this problem I found that the C terminal screw for the common bus side of the 24Volt transformer was at least a turn and a half loose. Not sure how it has worked for so long. Thanks Much
Thanks John! Glad you found my video useful :) Good luck with the furnace!
Excellent, practical video. Thank you very much. The comment about high efficiency Carrier furnaces and the plugging up condensate trap was exactly what my issue was. The tip for the bucket was spot on - about a gallon of water came out. After I cleaned the trap, everything ran perfectly.
Just have to say thank you so much for your videos, twice this year my furnace stopped working and both times I was able to fix it from watching your videos!
Thanks for the very helpful explanation. I was able to fix my furnace with just a paper clip. I also changed the filter based on advice from your other video. Everything works great now.
Excellent! Glad to hear that. Have a Merry Christmas!!
Thanks for making this. Informative, simple and straight to the point. We watched about a dozen videos before finding yours and it led us straight to the problem, and we were able to fix it ourselves - I wonderful relief since the soonest repair service was booked out for four days and we have a cold snap going on right now (always the way it goes, right?). This really saved our buns, not to mention made my husband feel pretty macho for fixing it “himself” ;) myself and his ego thank you!
I had an error code on my Furnace for the pressure switch. I watched your intuitive video on error codes and traced the cause to be condensate built up in the drain line, backing up into the vent motor which caused that motor to labor to run and trip out the system!
I am truly thankful for teacher/Techs like you for sharing these incredibly helpful videos!!
Thanks for your great advice! My blower port was clogged. I really appreciate your ability to communicate clearly in this video.
What a great, informative video! Wonderful job of explaining everything with all those little extra things to look for that others do not tell you. Very helpful. Thank you so much , and keep up the great videos.
You're welcome! Glad you found the video helpful! I appreciate you leaving a comment.
You fixed it! Loose wire after switching out the blower motor this summer. I was going CRAZY trying to figure it out. THANK YOU!
You're welcome! :) Glad you were able to find and fix the problem! Stay warm :)
You are a lifesaver! It’s 23 degrees out and 3 am on a Saturday and my furnace just went out. The error was saying pressure switch closed so I blew on the tubes and gently tapped the pressure switch and it worked! Can’t thank you enough!! ❤
Your videos are awesome. We came home from vacation to freezing temp and a furnace/heat pump that wouldn't start. I ran through your top 10, error codes indicated low pressure sensor. Found a little rock in the line, didn't work. Replaced the sensor, didn't work. Then saw the segment about cleaning the port with a paper clip... It was stuffed full of debris. I used a Dremel bit at first by hand and found it so bad I used the Dremel itself. Life saver! I couldn't get anybody out here, add if I did I probably would have been charged a huge boatload. THANK YOU FOR YOUR WELL MADE AND VERY INFORMATIVE VIDEOS!!!
At 11:30 on a Saturday night in December it stopped working and was able to get it running again! Thank you so much!
I truly appreciate your work here and the valuable info you give. Thanks to you I was just able to rule out a number of problems and get my furnace back up and running in minutes instead of having to wait until a furnace tech could come look at it. I appreciate the time and money you saved me, keep up the great work!
I had recently had to repair the condensate drain on my furnace, afterward I got a code 31. Thanks to this video I was able to realize I had put the pressure hoses on backward and switched ports! Working fine and saved me a couple hundred bucks! Thanks!
You are an absolute boss! Carrier 9200 was acting strange the past few days and finally gave up last night. It was a plugged condensate trap. Very helpful tip on having a bucket ready. And amount of crud that came out of the trap, my god. Thank you!
You are an absolute gem!!! Thank you for helping me...I had a clogged port. Bless you!
I was able to fix my furnace by watching your video. One of the big hoses had wet rusty garbage, so I cleaned it out with a wire. Thanks for the video!
Thank you for producing these videos -- very clear, thorough and helpful! I managed to kind of narrow down the issue with my furnace to the vent inducer assembly using instructions from other places. I was ready to replace it (which would have worked but cost $300). Then I found your videos and pinpointed the exact problem. Some dust or ash seemed to have gotten wet and clogged the port where the air pressure tube connects. When I found it, the clog had solidified and was rock hard. With your instructions I managed to fix everything for $0! 🤩
Everybody said it already..all your videos are great..to help the average person out of a bind and get their furnace working..Thank you..
Fantastic video. So well explained, well done. Helped me diagnose a pressure switch hose that had cracked because it was too short and was stressed because of bend that was too extreme where it was connected. $3 part and it's fixed. Thank you so much!!
$100 in parts and 3 frustrating days of trying to figure out what was wrong with my furnace. The culprit? The vent pipe was plugged up by a dried out wasp's nest. Would never have known that without this video. Thank you.
Is this on your 80% furnace. Is this the pipe on top of house
This is the most thorough coverage of furnace problems I have seen so far.

You sir are great! It's -18 degrees Celsius (0.4 degrees Fahrenheit) outside. Our house was down to 12 degree's celsius (53.6 Fahrenheit) inside. The furnace guy had been out once last week and cleaned inside the furnace and that seemed to help, but then this morning we got up to this coldness. I watched your video, walked outside, and stuck my finger in the intake tube for the furnace (high efficiency). There was a build up of snow inside, that had blocked the input tube and this was immediately dislodged with my finger. Instantly the furnace out port put out a little burst of moisture, and the furnace has been running fine and brought the temperature up by 4 degrees already in about 15 minutes. Thank you!
Best video on this error !!! Well done! I could repair mine without any problem just following these steps.
You are one of the Best People who describe the problem,
GOD BLESS YOU

Very concise! Was able to toubleshoot and get the furnace going again after replacing the reduction motor and then coming across a Pressure switch error. One of the 10 issues you point out did the trick. Not sure which one, but, it doesn't matter now. Saved lots of time and money! ...Thank you!
This is by FAR the most helpful video I've ever come across when trying to trouble-shoot any home repair/maintenance issues! I had issues with my high efficiency furnace, and tried multiple things that didn't work before finding your video. Most other videos only showed how to fix one problem. This was super helpful...thank you!
Thank you so much you help me fix my furnace at 4:30 am in the middle of winter in Chicago.
It is 2 am and I got my furnace working again because of you. It was a plugged condensate trap. Thank you so much for your help!
You're welcome!! Glad you were able to get it fixed, stay warm!
I hope you see this! I live in South Central Kentucky and we had a snowstorm yesterday (we usually never get much snow ever!). My heat went out today in my house. I was using my gas fireplace to help keep the house warm. It’s 15 degrees outside (62 degrees in my house) and I searched UA-cam and came across your video. I followed along your video, pausing and checking things as you went down your list. I was getting the pressure switch error. It ended up being that the port from the pressure switch where the tube attaches was clogged. But, I also think the intake vent might be clogged as well. Going to double check that tomorrow. As for now, the temp in my house is rising. Thank you so much for doing this video!!! It saved me a lot of money and made me smarter about my own unit.
My Carrier Infinity 48XL-A worked flawlessly for nearly 10 years. Then, the heat would not turn on. Your knowledge, troubleshooting expertise, and excellent presentations gave me the confidence to attempt to make a repair on my own. After reviewing many of your videos, I narrowed the problem down to a bad inducer motor or a defective pressure switch which would not close. The solution was unclogging the pressure switch port....a very simple fix...if you know what you're doing. The port was filled with a hard, white substance that looked similar to dried mineral deposits. As you recommended, I used a wire with moderate-level pushing to punch through the substance. The fix was SUCCESSFUL! Thank you!
Hey, thanks so much for this very informative video. Just like the previous post, it was Xmas eve and the furnace was not keeping the house warm. (“The night before Xmas & all thru the house-everyone was cold, including my spouse”). The worst timing-all the fam home, contemplating the jacked-up service call on the holiday, not being able to get a replacement part until after the holiday, etc. etc.-the ruminating had begun. I checked the service code-“High-Heat Pressure Switch or Relay did not close or reopened.” I have a Bryant and tried the troubleshooting step of cleaning the condenser trap. Ba da bing ba da boom-how lucky did I get. I began squeezed the tubing to see if there was any backed-up water and the water began gushing out into the trap and then out to the pump. I didn’t want to get my hopes up, but was thinking that this just may be the problem & solution. I disconnected the condenser trap, cleaned it out as instructed, reconnected everything, fired up the furnace, and let there be heat. No more service code, I am several hundred dollars richer, and everyone is happy! You are a life-saver my friend. Thank you, thank you, thank you!
Thanks
Your video was very clear and detailed. I was able to troubleshoot my issue and correct it in about 5 minutes. Thank You Sooooo MUCH! :)
This video helps me finding & ruling out the causes of my furnace not heating. days ago my furnace just did not work with 3 flashes on and the outside temperature was below 30s. I did some research, found this video ( watched Jay's other videos before and trusted him). Following his suggestions, checking in & out venting pipes, cleaning condensate trap/pipe, testing pressure switch with multimeter and finally end up at inducer motor. Ordered a new one right away and replaced it a day after. Boom, my furnace began to blow the warm air again. Thank you Jay. Save me lots of time & money. you are the guy know your stuffs and help others.
Checked the hose connector and the electrical connectors to the pressure switch , just wiggled them a bit, reset the power, and everything worked fine. Thanks! Saved me hundreds of dollars and hours of time!!!
Thank you for your videos. After your troubleshooting videos, I was able to successfully fix my AC and furnace. Great videos! Keep them coming.
Thank you Jay . helped me solve my problem. Pressure switch wasn't working because condensate was backed up all the way up my outlet pipe due to ice forming at the exit from the house..
Thank you for the knowledge my friend! I’m in HVAC-R classes and we do more book work then hands on so this helps alot
Glad to hear the video is helpful! Good luck with your studies! You picked a good career :)
Thank you so much sir. Our furnace stopped working on Christmas day so it looked like it was going to be a Dickensian Christmas for us, all huddled around a candle. And then I saw your videos, so I opened the furnace doors and followed everything you said - always being careful - and low and behold, my Lennox G61MPV had a bad motor capacitor. I used the opportunity to clean the combustion air inducer and the air pressure prove switches and hose connections. Now I feel like Scrooge after he woke up and am jumping (with my family) around our warm house with joy. THANK YOU!!!!!!!!
Thank you so much for your videos and your channel. I own rental properties and you just saved me $200-$300. I cleared 2 furnaces with plugged pressure switch ports with a paper clip. Thank you for giving me the knowledge and confidence to troubleshoot furnace issues in the future.
you are doing God's work young man...
Funny at the end, nice work on this one. Happy New Year 2019..
You are Fantastic! We are having severe financial problems so when the furnace wouldn't start this year I was just deflated. Didn't have the money to fix it. But after reading the back of my furnace panel, counting the blinks, and determining it was the low pressure switch I came to UA-cam and found you. Great video! I first tried clearing the pressure tubing then gently blew and sucked of the hose. Heard the switch make contact. put it back together and the furnaced fired right up! Dude, you saved me hundreds of dollar$ that I don't have right now. Keep coming out with these great videos! you're the best!!!
After 4 hours of disassembling, washing and vacuuming condensation box, every hose and vent... a suck on each pressure switch hose finally did it!!! Thank you immensely
Oh man, that sounds like quite the arduous task! Glad to hear that fixed the problem and it's working again!
Awesome video taught me a lot and helped me identify the problem...
Great job, and Thank you! This helped me get my furnace working! I had to clean the pipe that came from the small fan and was attached to the rubber hose. I used a copper wire pressed into there an went back and forth to clean it a bit. (issue was that i had the light flash 3, for Stuck Open Pressure Switch)
Glad to hear you were able to get it fixed! Thank you for leaving a comment, stay warm!
This is one of the best informative videos I ever seen on whatever I was looking for on You tube .Thanks Man.
Great stuff. Thanks to your video, I found where a bird went 30ft or so down my intake pipe and built a nest right on top of the firebox. Cleared it and I’m now basking in the heat of the house. Saved a bundle. Thanks so much!
Best trouble shooting vid I've ever seen. You were clear concise and informative. Very well explained. You know your stuff. Thanks So much !!! Liked and subscribed...BIG TIME .. 👍
Thank you! Glad you found the video useful! :)
@@WordofAdviceTV not just useful, you made me a hero to my sister and 85 yr old mother. The ignition switch was in plain sight and very easy to reach. I was able to visibly see the crack in it before even touching it. I was able to use a bbq lighter to simply spark the furnace to life, until maintenance showed up. I was able to keep the house warm this way for 5 hour's. Thanks again friend ..
Like I love to say .. There ain't no mix, up that UA-cam can't Fix up :)
You are the king of explaining things to the "I have no idea wtf I'm doing but I'm gonna youtube it before I spend 300 dollars for someone to tell me it just needed a pipe jiggled" crowd. 👍👍👍👍👍
This saved our bacon!!! For us it was a loose wire! You are so good at this! The way you communicate is 100% helpful! Thank you thank you thank you for sharing your valuable knowledge!!!!
I woke up to a non-working furnace this morning and just watched your video. The rubber hose attached to the pressure switch was loose .. presto it fired right up! Thanks from chilly Wisconsin!
You are the man!!!!
Watched 4 or 5 of your videos and it helped me diagnose and fix my furnace problem.
Will now be a subscriber for life!
I'm heating and cooling men and I really admire your big heart to share this with the people God bless you
Thank you! May God bless you and your family as well!
Thank you! You helped me find the plugged up hose going to the intake pressure switch. My Lennox HE furnace was showing a pressure calibration code error. Following your clear advice I found and fixed the problem. My family will be warm tonight.
I am forever grateful for this video. It explained every scenario and in laymens terms. They wanted $688 to replace the low pressure side and it wasn't even a failed switch. Besides, Icould purchase both switches on line for $30 and install in a matter of minutes. Thank you for educating me on the root cause of inoperable pressure switches. Meanwhile, I am by-passing it by waiting for the draft inducer to get up to speed and then jumpering around the switch.
