It is 2am. I noticed my house was getting cold the furnace wasn’t going. I am a single mom really struggling. My son is autistic it’s hard to get people in my house with him. I started to panic it’s freezing snowing. Your video I followed the best I could. My heat Is back on. Thank you so much for making this video you are a savior for me right now.
@@duMaurier15 how rude. As a single mom, sometimes we feel it is important to give a back story to show our level of appreciation. Be nice... it isn't too hard.
@@duMaurier15 Jesus, did you get up on the wrong side of the bed today? She's a single mom with an autistic son and you want to come on here and run your mouth? Have a better day buddy
It was the first day of cool temps and my house was 63°F. I turned on the heater and sure enough it was blowing, but only cold air. I watched your video. I opened my furnace panel, I looked at the flashing lights, I correlated it to the diagnostic on the sticker of the inside of the furnace. I replaced the filter, I didn’t have to bang on the thingy, but I pulled the plugs out, and when I put them back in my heater started working! I am so proud of myself, and I only tried it because of how clear and easy your video was. Thank you! Single female, 10pm and I’m so happy.
Hey Jay...You are my Furnace Fixer HERO!!!! After watching your video it took me exactly 2 minutes to fix my High Limit Switch that must have been out over 6 months. Of course, I heard the fan blowing and all the switches and button worked so I felt I was good to go...and of course I purchased room fans. Your step by step educational video save me of $225...from a so call professional quote...and now my home is HEATED, in no time. That Tapping trick on the High Limit Switch was amazing...and your other video, on cleaning your burners with a wired brush was fantastic...my burners look like new. By the way, I have never touched my Furnace...didn't even know a blinking Sight light was even suppose to be on. You make me proud to be a Female fixer upper in my home...Thankssssssssssssssssssss a whole lot!!!!! Keep up the good work!!!!
You are a genius!!! I knocked on the limit switch a couple times and the inducer motor started up right away (Goodman and the limit switch was round, just like you described it). I had furniture in front of the intake vent, which was probably the culprit...just to let your viewers know. Thanks again!!!!
This is our second time to have to refer to this video to fix our furnace. It’s been a couple cold seasons now since we fixed it the first time. It has been so helpful. Saved us a service call and cost of repair! Thank you so much for this wonderful tutorial!
I know this video is 3 years old. However, I followed the steps in this video and got my furnace working again. My upper limit was open, and I changed the air filter, but it still didn't work. Gave the sensor a few taps with the screw driver, and Voila it's working. Saved me at least $80 for a service call. Much appreciated 🙏 ☺️
Tapping it made it work! Noticed vents were blowing cold air, burners weren’t on, and flashing 4 lights. This video saved us a goods night rest, THANK YOU!
Thanks to your honesty I got my furnace running. Praise God! I cleaned up the fire sensor and changed the igniter; reset one of the thermal switches and took the other one out and tapped it on the floor. Now I know I have to keep the filter changed. :)
You're the best, Today on Christmas my furnace gave up, I followed the steps you suggested in your video. Changed the filter, tapped the high-limit switch and it worked, I will still get it serviced. Thank you you're a life saver. God bless.
Woke up to a very cold house this morning, went down to have a look at my thermostat, sure enough worse nightmare specifically with the COVID-19 situation.. called a furnace repair company.. $245 for a technician to come out on the weekend... given the fact I been out of work for 2 + weeks now.. I would of probably just waited out until tomorrow if I didn't have my girls 7&3 years old home with their mom.. Started watching UA-cam videos after watching maybe 3-4 came across yours . tried everything step by step in this video for 2 times.. 3rd time the MAGIC HAPPENED... Thanks to you I saved lot of $$$, and now our house is warm again.. great videos... keep up the life saving work.. you have a subscriber for life....
Thank you. Followed the instructions, and worked. Furnace back on. I tapped the furnace housing and the switch didn't reset. I removed it and tapped it and it reset. I would have diagnosed it and bought a new switch. Saved not only money, but the time to get the switch. Don't know why someone would give it a thumbs down. Two thumbs up!
Awesome! No one else has this. I had the same problem. No heat. Clogged filter. Four red lights. Other videos really didn’t help at all. Your’s nailed it. Thank you!
It's 2am. It's 11 degrees outside and my furnace died. You saved my pipes from freezing. I tried everything and this fixed it. You are an hvac Robin hood.
So I’m in New england today in middle of winter storm kenan. Of course my heat decided to go out and nobody would come for an emergency because our roads are closed. I tried this and it worked. Absolutely thrilled!! Thank youuu!!
Thank you sir!! Fan was constantly running throughout the night, was up waiting for it to shut off. House temp dropped to 62. Outside was 23. Found this video. Filter was embarrassingly dirty. Followed your steps of banging on switch, turned power back on and eagerly waited for start-up. Like magic I now have heat. Thank you so much.
Im an HVAC 3.89 grad and mine just did this. The school never taught us this could happen. I was going nuts trying to figure out wth was wrong. Totally overlooked the filter. Problem solved. TY dude
I just went to sleep at 1:30 a.m. on Saturday night and at 3 a.m. my wife wake me up and said is really cold I get up and check thermostat and it was at 58 degrees Fahrenheit; I went down to check the furnace, check filter and it was clean and four flashes were coming out the board and my inducer blower was not working, after wondering what to do for 45 minutes, I went to you tube to check a few videos, After checking other 2 videos I found your, after looking your video I went down my furnace again, I did hit the switch where you said and turn switch on and problem fixed. Thank you, my cousin is Ac/ heating thecnicician but leaves 1 hour from home and it will not come in the middle of the night and your video help me to not pay around one or two hundreds dollars for just someone to come and hit the switch. Thanks a lot, going back to bed now at 4 a.m. I learned something great tonight. THANKS A LOT BUD!
You are a Star ! Watching you is like watching this old house or one of those public broadcasting stations andyou communicate and show what you're doing so well anyone could follow it most likely and you're not boring
Got on google. Spent 30 minutes. Nothing. Got on UA-cam. Clicked on your video first. Fixed in 5 seconds. I could literally kiss you sir, thank you so much 🙏🏾🙏🏾🙏🏾
I love UA-cam. And people like you that make easy to understand, concise videos. I watched another video or two that were okay but didn’t resolve the issue-yours did. Thanks for saving me the service call and a cold night as temps are supposed to drop the next couple nights here in MN. Signed, A Grateful Dad
You are a lifesaver for me, twice!! Again, today my furnace was blowing cold air. Followed your steps and the problem is solved. In addition to your steps, I'm glad u mentioned what could be causing this. Checked my filter and it looked exactly the same and then I remembered that my wife had gotten few new jars of a candle which we have burning. Time to have a conversation with the wife about the candles :-). I'll make sure you donate to your page directly since your advice has helped me twice now. Thanks again!
Thanks Bro, you saved the day! After first snow in Minnesota yesterday, furnace stopped heating and I had called for service but they did not show up because it's a weekend and they had a lot of calls. So we have been cold all day and I decided to search on youtube and came across this video around an hour ago. It's 11 PM now and after a couple of wacks to the limit switch, the furnace is running again and heating the house!
That's what I like to hear! :) Glad I was able to help a fellow Minnesotan! It was snowing all day today too. Thank you for leaving a comment, stay warm!
thank you so much for your videos. I sure wish I had found them last year. i'm a 60 yr old grandma who honestly doesn't know anything about mechanical things. i'm actually afraid to touch anything that uses electricity, gas, propane, etc. i'm afraid it will blow up. last year I practically rebuilt the front of my nordyne 90% propane furnace in the middle of winter. my electric bill doubled while I replaced almost everything trying to get the furnace to work. I kept getting different combinations of red blinks after I would replace a piece. I finally got it working and it was ok until a couple of weeks ago when I noticed that it was pouring cool air out of my floor vents again. this time the furnace would fire up and then the flames would go out after several minutes. sometimes the flames would stop burning where they were supposed to burn and an orange flame would light up inside one or two of the burner tubes. no actual "blow back", but the furnace would shut off after a few minutes and just cool air would come out of my vents. it would try to recycle but the same thing would happen. I found your videos and noted a lot less that I could replace this time around. I had a yellow blinking light which on my furnace means a low flame fault. I bought a new flame sensor because I was able to rub some gunk off of it but about 2/3's of it was blackened and would not clean off. I put the new flame sensor in, turned on my furnace and it seemed to stay on a little longer than the first time but still faulted out to the blinking yellow light and the cool air. I checked your videos again and started taking the burner box apart to try to clean the burners. got to a point where my available tools wouldn't allow me to continue--can't reach 2 of the screws on the right side of it. i'm trying to loosen things to a point where I can reach in and clean the burners on the right side without removing them. I cleaned the orifices in that bar from the gas bar in front of the burners. the burner by the flame sensor was blackened and I can't seem to get that clean either. I'm going to try to clean the condensate tubes too. I think this is all I have left to try unless you have any other ideas. it's been pretty cold here in the upper peninsula of Michigan as i'm sure you know--below zero wind chills at night and we've gotten so much snow that my garage just collapsed early this morning. so as you might have guessed....there's no new furnace for me any time soon. thanks again for your videos. you do a great job of teaching at the right level and showing us everything that we need to see--so many others just tell us what they've done but don't show the video. The only other comment I have is.....you don't happen to have a single father who knows as much as you do about all of this, do you?
I have (2) Bryant Plus 90i Furnaces. My problem was with one, it was blowing out cool air for a while, then cuts off and stays off for a long period of time then turns back on blowing cool air again. I called the HVAC guy and he charged me $435.00 just only to replace a pressure switch. Months later, a similar problem began with my other furnace. So I went on Ebay and purchased a Pressure switch costing $125.00 and installed it myself. Now I must say its working great! Thank You.
@@willarddickerson921 Nice work. I have learned so much about furnaces with the help of this guy and others on UA-cam. I have always been mechanically inclined but watching experienced folks helps out so much. I have replaced almost every part of my furnace the last 2 years.. in fact I have a spare ignitor now so if it breaks I can fix it right away. Next fall I may try replacing the entire thing as I know the heat exchanger is probably going to go bad sometime. It's 15 years old and that seems to be the life of appliances nowadays unfortunately.
Jack, thank you once more. It works. It is below 10 degrees here and I have no protection plan right now. I was freaking out about my family being cold. Thank you for giving a very clear instructions. God Bless.
It worked just as you suggested. I can't believe I did it all by myself. I'm not a handy girl, but I was having problem with my furnace blowing cold air. I saw your video, followed your instructions and repaired it myself. It took me less than 2 minutes. I have a friend who is on his way over to fix it for me, he won't believe I did it either. Thank you so much. I was tired of being cold and waiting for someone to come by to look at it. Thank you thank you!!!!!
Great video! I was able to troubleshoot my son’s furnace when he experienced no heat in his home. With a newborn in the house this vid came in the nick of time! Thanks so much!!
my furnace was not heating up. I watched a couple of your videos and after running to Lowes for a new filter I made a second trip to Lowes for a rachet set. it took me 5 minutes and I have heat. Thank you so much for helping me
2 am, heater blowing cold air, thermostat reading 68°, thank God i found your video. Now the heater works like clock work, thank you man and God bless!!!
Thanks for the video, temperature dropped from 70 to 66F overnight. Removed limiter, tapped it a few times, re-installed, two minute job. Worked right away, wife happy, back to 70 degrees.
I realize you put this up something like 3 years ago but you just saved me. I don’t have the same type of switch like you so mine was easier to reset but thanks to you I knew what to look for. Then I was able to look up how to reset mine. My furnace actually has 2 of these. Anyway, thank you so much.
in April of 2020, our furnace started blowing only cool air through the house. A little Googling and I landed at this video. It fixed it and the process only took ten or 15 minutes! I just wanted to say thanks! Saved us the hassle of having someone out at the beginning of the pandemic and saved a bunch of money.
Saved my life this morning! With all this COVID stuff going on, we were really worried that we were going to have a service man come in to fix it. Found your video and had it up and running within 2 minutes of watching it! Thank you!!! Mine is a Lennox furnace. The lights are green and red, alternating slow flashes (1 per second) to indicate a problem with this switch. Change your filter!
My heater was out for about 3 weeks and when I went online and watched this video for just 5 minutes, I was able to followed the first few steps and now my heater and up and running again. Thank you for sharing knowledge!
This is such a great tutorial. This was exactly my furnace's issue, and I was able to fix it and get my two kids and I warm again in the -20 degree weather! Thank you, thank you!!
Middle of night our house was so cold and heater was blowing air but it wasn't hot. We watched this video and found out that it was overheated like you said and we hit it with the end of a screwdriver like you said and boom! Hot air! It worked! We changed out our filter now because it was indeed dirty and needed changing. Thank you for saving us money and from having a very cold night! Awesome video!!
Thank you for your help. Our furnace stopped working in the middle of the night and we have a little baby. It’s 15F out tonight. You really helped us a lot.
You're welcome, I love hearing that! I am happy to know that my video helped you get the furnace back up and running! I can't imagine how it feels since even I get a little worried if my furnace stops heating.
You are amazing, clear, concise, and to the point. The envy of some companies (not all) who take advance of innocent non-knowledgeable home owners. Thank you for this and other informative videos, helped me immensely as I’m sure others. Thank you! Subscribed!
You are welcome! Thank you for the positive review! 😄 I'm glad to hear that the videos have been helpful for you and appreciate you subscribing. Stay warm and have a Merry Christmas!!
Thanks so much. Eight degrees and no heat. We had been cutting a lot of tile in the garage, probably clogged the filter. A few raps on the switch got her up and running. You are awesome, we are grateful.
This morning my furnace would blow cold air. Watched your video, changed filter, tap the hot limit switch as you’d mentioned in the video. It’s working great and blowing warm/hot air. Thank you!
Ok, you are an absolute legend!! Dog hair plugged furnace filter was the issue. Fault signal was high limit stuck open . Took it out and tapped a couple times. Reinstalled and then furnace fired right up. Thank you for saving me $200 and teaching me this !!!
It is currently Christmas Eve, 2022 at 10:52 PM, and this WORKED! We came home to a house at 45 degrees and it has been a super stressful hour or so figuring this out. Thank you so much for actually explaining the limiter and bi-metal, it made sense to me and every other video we watched just said the switch needed replacement. Thank you so much!!
Same exact thing here but Christmas Day! 1st year we got -30 temps and blower stopped. Currently chugging hot coffee and going to tackle this. As you Said 1st video that was thorough and didn't just say calm your hvac as we all know on Christmas day a simple fix could cost thousands just to have someone come. Thanks for the video OP!
MY friend...that wax from the candles is AN amazing deduction of why filters go so quick! Thank you for the rest of the information as well, I forgot my filter to change it out as well, and now I think I might be in a lock out.
Thanks for the info. This just happened to me this morning. My filter did not look dirty at all and was not my usual time to change it. I changed the filter anyway and so far everything has been working.
THANK YOU! You saved me paying hundreds of dollars to incompetent HVAC companies. They diagnosed my Trans furnace problem as the air pressure switch, and were going to charge $380 for the part and another $100 to go get it on a Saturday. Was the wrong diagnosis, would have been the wrong part, and many hours wasted. Thank you! I've subscribed. :)
You the man, I had the pressure switch code, but everything was ok, then I tapped on the limit switch and it started working! I called the emergency repair service and said nevermind. You rock!
You are a genius and a Godsend! This was my problem and all I had to do is tap the end piece of metal and it fired right up. Saved me a hundred dollar service call for a little blood, sweat and wine lol
Before hearing your story with your wife. Heater not working just blowing cold air. After listening to the story and watching the video we have heat again. My furnace was locked out. Thank you ✌🏾
I consider myself a jack of all trades. Im one of those guys who’s not afraid to jump into any Mr fix it project and usually landing on both feet. That being said videos like yours help guys like me immensely. Some people think of trades, such as HVAC, are just grunt jobs for the uneducated. We know that’s not true. The trades are the jobs that keep our nation going. With out the trades everything would grind to a stop. If it was so menial, why do they call someone to fix it. Thanks for all your videos and helping me to expand my knowledge so I can help my family and friends
You're a life and pocket book saver. I didn't check the code, just rapped on the limit switch, turned everything back on, and it started right up. Will definitely be changing the filters regularly from now on.
Christmas day morning and your video helped bring us heat! We overheated and shut off... Overnight, temps hit -15°f/-26°c, we had a ton of drifting snow, and our outside vents had snowed and iced over. Knocked off the ice, reset the switch, and we are celebrating a better Christmas thanks to you!
Thank you it worked I just changed the filter and smacked the switch a few times as told. It worked. Today is Christmas it saved me a service call and saved my family from a cold night as well. Thank you.
Brother, it’s midnight.. the furnace isn’t working right.. it’s cold.. I’ve been searching the internet for 4 hours while my wife and young kids are sleeping upstairs with space heaters on… your video helped me get the heat running again and saved me money. Thank you!
I would say this video is the most useful I get in years, considering how urgent it is having no heat in cold days. Clear symptom and instruction, thumb up!
You have an incredible ability to communicate effectively. Superior communication skills! Maybe you should be in broadcasting----but then again, on You Tube, you basically are!
My goodness. Thank you so much for the tip. Banging didn't work initially so I took it out and tap it few times and put it back. Viola! Works! Thank you so much! Wow!
Thanks for mentioning that candles can produce a waxy coating on the air filter. I recently replaced a white filter after a month of use and it was jet black. This has never happened before. We religiously change our filter every month. We believe the culprit was using a plugin air freshener, and then burning two large candles. Softer candles produce more soot than others. So I think the plugging air freshener left an oily coating on the filter and burning the two candles left a black soot that was caught by the oily residue causing the filter to be a jet black color after only one month of use. Jay brought up a good point, burning candles can leave a waxy coating that you might not notice and this can plug up the filter and damage your HVAC.
Tapping on the switch worked! We’ve been-32 wind chill for days so our furnace was overworked. Plus, multiple power outages. Thanks again for the help.
I only can say thank you so much God bless you and people like you I have no idea what to do, watching couple video , tell me what to do , and when I start watching your , I said naaaaa can’t be that simple You save me Thank you
I recently had trouble with my unit not blowing hot air. Long story short it was WATER in the drain tube. I have a 90 percenter and over the last 16 years sand clogged my P trap and the water could not drain. Thank you for the videos, they helped me sort out the problem one component at a time. We blew out the p trap with compressed air, now it drains and the heater stopped failing.
As always, another awesome video from your channel. You helped me fix my furnace this morning in 5 minutes. Turning the furnace off, let it sit for a few seconds, and turning it off cleared the error code and just like that, I now have heat again. Appreciate your advice!!!
Thank you, it worked for me too. My wife woke me up at 4am telling me that the furnace isn’t working. Did a quick UA-cam search and found your video. I hit the switch couple times with a screw driver and started working. We changed the filter recently and apparently we put it in the wrong way. Thanks again
This video along with a few others from YOUR channel saved my icy behind tonight! You are so thorough and made this easy to understand. Thank you thank you thank you!
last year a professional showed me how to fix this switch. tonight we got home to a cold house with chores ahead, and I couldnt remember the protocol, thanks for your suggestions, because my memory literally created a switch array that doesnt seem to exist and I wouldnt have figured this out tonight without your walk through and my wifes calm lead. warm house, still time to get caught up tonight, no lost workshift tomorrow and hopefully a proffesional isnt scheduled for tomorrow God willing. Guess I need to keep on those filters more often. you ROCK sir!
this video solved my issue! Noticed the furnace blowing cold air for hours and knew something was wrong. I changed the air filter, which was dirty from the past three months, I also forgot... but I couldnt find anything that would fix the problem until I found this video. Thank you so much!
Very nice, clear and concise presentation. Thank you for taking the mystery out of diagnosing this problem. Can't understand the "thumbs down" must be very insecure folks! Thank you again!
Hello!! Thank you!! I had the 4 lights blinking quickly. We had new lights put in the house so the handyman kept turning the main breaker on and off. My husband worked on it last night and by morning it was 54 in the house, 20 degrees outside. I woke up freezing cold and watched this video! I banged on it 4 times like you and it turned back on after I flipped the switch!! My husband is impressed at how I got it back on. I won't tell him my secret!! Thank you!!
Thank you, bro! I sincerely and genuinely appreciate you and this video, especially on a cold day like this. I literally just banged on the open limit switch a few times, and BOOM!, it was back on. Thanks again, and may Allah bless you and your loved ones!

I just went to sleep at 1:30 a.m. on Saturday night and at 3 a.m. my wife wake me up and said is really cold I get up and check thermostat and it was at 58 degrees Fahrenheit; I went down to check the furnace, check filter and it was clean and four flashes were coming out the board and my inducer blower was not working, after wondering what to do for 45 minutes, I went to you tube to check a few videos, After checking other 2 videos I found your, after looking your video I went down my furnace again, I did hit the switch where you said and turn switch on and problem fixed.
Thank you, my cousin is Ac/ heating thecnicician but leaves 1 hour from home and it will not come in the middle of the night and your video help me to not pay around one or two hundreds dollars for just someone to come and hit the switch.
Thanks a lot, going back to bed now at 4 a.m.
I learned something great tonight.
THANKS A LOT BUD!
You are a Star ! Watching you is like watching this old house or one of those public broadcasting stations andyou communicate and show what you're doing so well anyone could follow it most likely and you're not boring
After watching several furnace videos, This is the one that worked. Thank you!
Got on google. Spent 30 minutes. Nothing. Got on UA-cam. Clicked on your video first. Fixed in 5 seconds. I could literally kiss you sir, thank you so much 🙏🏾🙏🏾🙏🏾
I love UA-cam. And people like you that make easy to understand, concise videos. I watched another video or two that were okay but didn’t resolve the issue-yours did. Thanks for saving me the service call and a cold night as temps are supposed to drop the next couple nights here in MN. Signed, A Grateful Dad
You are a lifesaver for me, twice!! Again, today my furnace was blowing cold air. Followed your steps and the problem is solved. In addition to your steps, I'm glad u mentioned what could be causing this. Checked my filter and it looked exactly the same and then I remembered that my wife had gotten few new jars of a candle which we have burning. Time to have a conversation with the wife about the candles :-). I'll make sure you donate to your page directly since your advice has helped me twice now. Thanks again!
Thanks Bro, you saved the day! After first snow in Minnesota yesterday, furnace stopped heating and I had called for service but they did not show up because it's a weekend and they had a lot of calls. So we have been cold all day and I decided to search on youtube and came across this video around an hour ago. It's 11 PM now and after a couple of wacks to the limit switch, the furnace is running again and heating the house!
That's what I like to hear! :) Glad I was able to help a fellow Minnesotan! It was snowing all day today too. Thank you for leaving a comment, stay warm!
thank you so much for your videos. I sure wish I had found them last year. i'm a 60 yr old grandma who honestly doesn't know anything about mechanical things. i'm actually afraid to touch anything that uses electricity, gas, propane, etc. i'm afraid it will blow up. last year I practically rebuilt the front of my nordyne 90% propane furnace in the middle of winter. my electric bill doubled while I replaced almost everything trying to get the furnace to work. I kept getting different combinations of red blinks after I would replace a piece. I finally got it working and it was ok until a couple of weeks ago when I noticed that it was pouring cool air out of my floor vents again. this time the furnace would fire up and then the flames would go out after several minutes. sometimes the flames would stop burning where they were supposed to burn and an orange flame would light up inside one or two of the burner tubes. no actual "blow back", but the furnace would shut off after a few minutes and just cool air would come out of my vents. it would try to recycle but the same thing would happen. I found your videos and noted a lot less that I could replace this time around. I had a yellow blinking light which on my furnace means a low flame fault. I bought a new flame sensor because I was able to rub some gunk off of it but about 2/3's of it was blackened and would not clean off. I put the new flame sensor in, turned on my furnace and it seemed to stay on a little longer than the first time but still faulted out to the blinking yellow light and the cool air. I checked your videos again and started taking the burner box apart to try to clean the burners. got to a point where my available tools wouldn't allow me to continue--can't reach 2 of the screws on the right side of it. i'm trying to loosen things to a point where I can reach in and clean the burners on the right side without removing them. I cleaned the orifices in that bar from the gas bar in front of the burners. the burner by the flame sensor was blackened and I can't seem to get that clean either. I'm going to try to clean the condensate tubes too. I think this is all I have left to try unless you have any other ideas. it's been pretty cold here in the upper peninsula of Michigan as i'm sure you know--below zero wind chills at night and we've gotten so much snow that my garage just collapsed early this morning. so as you might have guessed....there's no new furnace for me any time soon. thanks again for your videos. you do a great job of teaching at the right level and showing us everything that we need to see--so many others just tell us what they've done but don't show the video. The only other comment I have is.....you don't happen to have a single father who knows as much as you do about all of this, do you?
I have (2) Bryant Plus 90i Furnaces. My problem was with one, it was blowing out cool air for a while, then cuts off and stays off for a long period of time then turns back on blowing cool air again. I called the HVAC guy and he charged me $435.00 just only to replace a pressure switch. Months later, a similar problem began with my other furnace. So I went on Ebay and purchased a Pressure switch costing $125.00 and installed it myself. Now I must say its working great! Thank You.
Thank you.
@@willarddickerson921 Nice work. I have learned so much about furnaces with the help of this guy and others on UA-cam. I have always been mechanically inclined but watching experienced folks helps out so much. I have replaced almost every part of my furnace the last 2 years.. in fact I have a spare ignitor now so if it breaks I can fix it right away. Next fall I may try replacing the entire thing as I know the heat exchanger is probably going to go bad sometime. It's 15 years old and that seems to be the life of appliances nowadays unfortunately.
Jack, thank you once more. It works. It is below 10 degrees here and I have no protection plan right now. I was freaking out about my family being cold. Thank you for giving a very clear instructions. God Bless.
It worked just as you suggested. I can't believe I did it all by myself. I'm not a handy girl, but I was having problem with my furnace blowing cold air. I saw your video, followed your instructions and repaired it myself. It took me less than 2 minutes. I have a friend who is on his way over to fix it for me, he won't believe I did it either. Thank you so much. I was tired of being cold and waiting for someone to come by to look at it. Thank you thank you!!!!!
You're very welcome! :) Glad to hear you were able to get the furnace fixed yourself! Thank you for leaving a comment, stay warm!!
Great video! I was able to troubleshoot my son’s furnace when he experienced no heat in his home. With a newborn in the house this vid came in the nick of time! Thanks so much!!
my furnace was not heating up. I watched a couple of your videos and after running to Lowes for a new filter I made a second trip to Lowes for a rachet set. it took me 5 minutes and I have heat. Thank you so much for helping me
2 am, heater blowing cold air, thermostat reading 68°, thank God i found your video. Now the heater works like clock work, thank you man and God bless!!!
Thanks for the video, temperature dropped from 70 to 66F overnight. Removed limiter, tapped it a few times, re-installed, two minute job. Worked right away, wife happy, back to 70 degrees.
I realize you put this up something like 3 years ago but you just saved me. I don’t have the same type of switch like you so mine was easier to reset but thanks to you I knew what to look for. Then I was able to look up how to reset mine. My furnace actually has 2 of these. Anyway, thank you so much.
in April of 2020, our furnace started blowing only cool air through the house. A little Googling and I landed at this video.
It fixed it and the process only took ten or 15 minutes! I just wanted to say thanks! Saved us the hassle of having someone out at the beginning of the pandemic and saved a bunch of money.
Saved my life this morning! With all this COVID stuff going on, we were really worried that we were going to have a service man come in to fix it. Found your video and had it up and running within 2 minutes of watching it! Thank you!!!
Mine is a Lennox furnace. The lights are green and red, alternating slow flashes (1 per second) to indicate a problem with this switch.
Change your filter!
My heater was out for about 3 weeks and when I went online and watched this video for just 5 minutes, I was able to followed the first few steps and now my heater and up and running again.
Thank you for sharing knowledge!
Great video. I was able to fix my cold air blowing furnace with the help of your video. Thanks for your help.
This is such a great tutorial. This was exactly my furnace's issue, and I was able to fix it and get my two kids and I warm again in the -20 degree weather! Thank you, thank you!!
Middle of night our house was so cold and heater was blowing air but it wasn't hot. We watched this video and found out that it was overheated like you said and we hit it with the end of a screwdriver like you said and boom! Hot air! It worked! We changed out our filter now because it was indeed dirty and needed changing. Thank you for saving us money and from having a very cold night! Awesome video!!
I'm happy to hear that the video saved the night! :) Thank you for coming back to leave a comment, stay warm!
I had a same thing I didn't replace my filter yet (i will) its 5AM but right now it's working thank you!!!
Thank you for your help. Our furnace stopped working in the middle of the night and we have a little baby. It’s 15F out tonight. You really helped us a lot.
You're welcome, I love hearing that! I am happy to know that my video helped you get the furnace back up and running! I can't imagine how it feels since even I get a little worried if my furnace stops heating.
Wow! You have a UA-cam career my friend. That was amazing fast, funny and saved me a lot of money! You deserve a lot more than just this comment!
You are amazing, clear, concise, and to the point. The envy of some companies (not all) who take advance of innocent non-knowledgeable home owners. Thank you for this and other informative videos, helped me immensely as I’m sure others. Thank you! Subscribed!
You are welcome! Thank you for the positive review! 😄 I'm glad to hear that the videos have been helpful for you and appreciate you subscribing. Stay warm and have a Merry Christmas!!
Man that was the best way someone have ever explain something ... thanks a lot God bless u bro 🙏🏿☝🏿
This was it! Hit it with a screwdriver and it worked. Life saver. It was cold! Thank you!
Thanks so much. Eight degrees and no heat. We had been cutting a lot of tile in the garage, probably clogged the filter. A few raps on the switch got her up and running. You are awesome, we are grateful.
Happy to hear that! :) Glad you were able to get it fixed and the video helped. Stay warm!
Thank you! Great video! Woke up this morning and the thermostat was at 57. Watched this video while my coffee was brewing and was able to fix it.
This morning my furnace would blow cold air. Watched your video, changed filter, tap the hot limit switch as you’d mentioned in the video. It’s working great and blowing warm/hot air. Thank you!
Ok, you are an absolute legend!! Dog hair plugged furnace filter was the issue. Fault signal was high limit stuck open . Took it out and tapped a couple times. Reinstalled and then furnace fired right up. Thank you for saving me $200 and teaching me this !!!
Nothing makes me happier when I give something a good whack and it turns on! Thank you for the awesome videos!
I’m just want to said thank you so much 4 your help and information. I’m just got my hvac license and watching your videos is really helpful.
It is currently Christmas Eve, 2022 at 10:52 PM, and this WORKED! We came home to a house at 45 degrees and it has been a super stressful hour or so figuring this out. Thank you so much for actually explaining the limiter and bi-metal, it made sense to me and every other video we watched just said the switch needed replacement. Thank you so much!!
Same exact thing here but Christmas Day! 1st year we got -30 temps and blower stopped. Currently chugging hot coffee and going to tackle this. As you Said 1st video that was thorough and didn't just say calm your hvac as we all know on Christmas day a simple fix could cost thousands just to have someone come. Thanks for the video OP!
MY friend...that wax from the candles is AN amazing deduction of why filters go so quick! Thank you for the rest of the information as well, I forgot my filter to change it out as well, and now I think I might be in a lock out.
Thanks for the info. This just happened to me this morning. My filter did not look dirty at all and was not my usual time to change it. I changed the filter anyway and so far everything has been working.
This is the second time I've watched your videos and found and fixed my furnace.
Thank you and God bless you, young man 🙏
I love to hear that the videos have been helpful! Thank you, I receive the blessing and may the Lord bless you and yours as well!
THANK YOU! You saved me paying hundreds of dollars to incompetent HVAC companies. They diagnosed my Trans furnace problem as the air pressure switch, and were going to charge $380 for the part and another $100 to go get it on a Saturday. Was the wrong diagnosis, would have been the wrong part, and many hours wasted. Thank you! I've subscribed. :)
I see we are not the only grateful people here. You saved us an emergency service call on a weekend. Liked and subscribed. Thanks so much.
You're welcome! Glad to hear you were able to get the furnace working! Stay warm.
Thank you for liking and subscribing! :)
Thanks for helping! That was a great video and you saved us on a VERY COLD night!! We are now your #1 fans!!
You the man, I had the pressure switch code, but everything was ok, then I tapped on the limit switch and it started working! I called the emergency repair service and said nevermind. You rock!
You are a genius and a Godsend! This was my problem and all I had to do is tap the end piece of metal and it fired right up. Saved me a hundred dollar service call for a little blood, sweat and wine lol
Easy peasy. Changed the filter. Furnace is good. Your’s was the best diagnostic. 👌
Excellent breakdown for diagnosing and testing limit switch issues! $10 part is much better than a service call. Thanks for the video.
This guy knows what he is doing. I fixed my furnace on 10m. Thank you sir.
Keep sharing more videos
Before hearing your story with your wife. Heater not working just blowing cold air. After listening to the story and watching the video we have heat again. My furnace was locked out. Thank you ✌🏾
I consider myself a jack of all trades. Im one of those guys who’s not afraid to jump into any Mr fix it project and usually landing on both feet. That being said videos like yours help guys like me immensely. Some people think of trades, such as HVAC, are just grunt jobs for the uneducated. We know that’s not true. The trades are the jobs that keep our nation going. With out the trades everything would grind to a stop. If it was so menial, why do they call someone to fix it. Thanks for all your videos and helping me to expand my knowledge so I can help my family and friends
You're a life and pocket book saver. I didn't check the code, just rapped on the limit switch, turned everything back on, and it started right up. Will definitely be changing the filters regularly from now on.
Happy to hear it was a fast fix! :) Stay warm!
Christmas day morning and your video helped bring us heat! We overheated and shut off... Overnight, temps hit -15°f/-26°c, we had a ton of drifting snow, and our outside vents had snowed and iced over. Knocked off the ice, reset the switch, and we are celebrating a better Christmas thanks to you!
Wow we must protect this
Man at all Costs, I owe u my career🙌🏽
Dude I was literally Shaking ( so cold) and you saved me. Thank you ! We should all pay you somehow. ( At least few bucks cause you deserve it)
Thank you for taking the time to make this video. Your banging on the switch did the trick for me! Same issue... Neglected filter.
I have watched a couple of your videos. Thank you for making your furnace videos to both you and to your wife.
My furnace if back up and running thanks to your help 🙂 🙏 thank you very much for sharing your experience! God bless you and your family.
Thank you it worked I just changed the filter and smacked the switch a few times as told. It worked. Today is Christmas it saved me a service call and saved my family from a cold night as well. Thank you.
Thank you was able to install a 90 plus furnace in my home in the middle of last winter because of instructional videos such as yours. God Bless you.
Brother, it’s midnight.. the furnace isn’t working right.. it’s cold.. I’ve been searching the internet for 4 hours while my wife and young kids are sleeping upstairs with space heaters on… your video helped me get the heat running again and saved me money. Thank you!
I would say this video is the most useful I get in years, considering how urgent it is having no heat in cold days. Clear symptom and instruction, thumb up!
You have an incredible ability to communicate effectively. Superior communication skills! Maybe you should be in broadcasting----but then again, on You Tube, you basically are!
Just fixed my furnace, because of you. Thanks a million! You are the greatest!
My goodness. Thank you so much for the tip. Banging didn't work initially so I took it out and tap it few times and put it back. Viola! Works! Thank you so much! Wow!
i love this guy. he's so detailed but straight to the point.
No he's not... the story about his wife blah, blah, was unnecessary filler.
Thanks AGAIN!! I fixed my sister’s heating issue. Lots of LIKES!
Nate from Long Beach California.
Thanks for mentioning that candles can produce a waxy coating on the air filter. I recently replaced a white filter after a month of use and it was jet black. This has never happened before. We religiously change our filter every month. We believe the culprit was using a plugin air freshener, and then burning two large candles. Softer candles produce more soot than others. So I think the plugging air freshener left an oily coating on the filter and burning the two candles left a black soot that was caught by the oily residue causing the filter to be a jet black color after only one month of use. Jay brought up a good point, burning candles can leave a waxy coating that you might not notice and this can plug up the filter and damage your HVAC.
Tapping on the switch worked! We’ve been-32 wind chill for days so our furnace was overworked. Plus, multiple power outages. Thanks again for the help.
I only can say thank you so much
God bless you and people like you
I have no idea what to do, watching couple video , tell me what to do , and when I start watching your , I said naaaaa can’t be that simple
You save me
Thank you
I recently had trouble with my unit not blowing hot air. Long story short it was WATER in the drain tube. I have a 90 percenter and over the last 16 years sand clogged my P trap and the water could not drain. Thank you for the videos, they helped me sort out the problem one component at a time. We blew out the p trap with compressed air, now it drains and the heater stopped failing.
As always, another awesome video from your channel. You helped me fix my furnace this morning in 5 minutes. Turning the furnace off, let it sit for a few seconds, and turning it off cleared the error code and just like that, I now have heat again. Appreciate your advice!!!
Thank you, it worked for me too. My wife woke me up at 4am telling me that the furnace isn’t working. Did a quick UA-cam search and found your video. I hit the switch couple times with a screw driver and started working. We changed the filter recently and apparently we put it in the wrong way.
Thanks again
Once again, UA-cam saves me time and money.
This video along with a few others from YOUR channel saved my icy behind tonight! You are so thorough and made this easy to understand. Thank you thank you thank you!
You just saved my household a bunch of money, thank you!
last year a professional showed me how to fix this switch. tonight we got home to a cold house with chores ahead, and I couldnt remember the protocol, thanks for your suggestions, because my memory literally created a switch array that doesnt seem to exist and I wouldnt have figured this out tonight without your walk through and my wifes calm lead.
warm house, still time to get caught up tonight, no lost workshift tomorrow and hopefully a proffesional isnt scheduled for tomorrow God willing. Guess I need to keep on those filters more often.
you ROCK sir!
Thank you! Haven’t had heat for a few weeks and this is all it was. I though I was going to have to fork out a bunch of money to get it fixed.
Happy to hear you were able to get it fixed! :) Stay warm!
this video solved my issue! Noticed the furnace blowing cold air for hours and knew something was wrong. I changed the air filter, which was dirty from the past three months, I also forgot... but I couldnt find anything that would fix the problem until I found this video. Thank you so much!
Very nice, clear and concise presentation. Thank you for taking the mystery out of diagnosing this problem. Can't understand the "thumbs down" must be very insecure folks! Thank you again!
Thumbs down was a furnace repair man.
Hello!! Thank you!! I had the 4 lights blinking quickly. We had new lights put in the house so the handyman kept turning the main breaker on and off. My husband worked on it last night and by morning it was 54 in the house, 20 degrees outside. I woke up freezing cold and watched this video! I banged on it 4 times like you and it turned back on after I flipped the switch!! My husband is impressed at how I got it back on. I won't tell him my secret!! Thank you!!
Thank you, bro! I sincerely and genuinely appreciate you and this video, especially on a cold day like this. I literally just banged on the open limit switch a few times, and BOOM!, it was back on. Thanks again, and may Allah bless you and your loved ones!
Hey It took me 12:07 seconds to watch your video. It took me :38 seconds to fix my furnace at NO cost me. You are amazing..
Thank you so much! This is exactly what was wrong with our furnace! Such an easy fix. We're very happy we didn't have to call a repairman.
Glad to hear that! :) Thank you for leaving a comment, stay warm!
