Furnace Not Working - The Most Common Fix

Furnace not working or wont turn on. Is your furnace not working or perhaps the furnace is turning on but only for a few seconds? Turns on and off repeatedly. In this video I go over the most common furnace problem. This is the all-time reigning champion. The furnace flame senor. I show how to find it, where it is located, what to look out for, how to clean it, and other helpful tips. This video is pretty much flame sensor 101. I have another video that is flame sensor 102. If you would like more information on the flame sensor, do check out the other video as well.

4 years later and still making an impact on lives!!! Woke up at 4am to a 60 degree house in a Michigan winter! Ran around placing extra blankets on my kiddos and immediately found your video! Only had a $2 bill in the house that I won a few months ago but I guess it truly was lucky!!! Heats blowing and temp is rising!!! Thanks a million times!!!!

[erics]

THANK YOU!!! Its Sunday. My furnace is not working and the temp tonight is going to be 37 degrees. I cleaned the sensor and the furnace fired right up! You just saved me $$ and a long cold night.

-30 here this morning (Winnipeg Canada) and out for my morning skate when my wife called and the house is only 17C and the furnace wasn't working. Rushed home, wife had every elec heater she could find on, oven on, oven door open and fireplace burning on full. I panicked, (Sun AM) then watched the above video and amazing, cleaned the sensors and the furnace is up and running. THANK YOU for the help and the added "husband" points I earned from my wife!!!!

[fameekajenkins]

Sir, I sincerely thank you and have the upmost respect for you and your scholastic provision! I am a single mom and when these type of break downs occur, I pray to God for a way to resolve them. In this instance, my furnace stopped blowing hot. I was guilty of forgetting to change out the filters, so they were indeed dirty. Your repair guidance defined the issues and provided me with the knowledge and skillset to resolve it within a matter of minutes. I can only imagine what you saved me in charges I would’ve incurred from an HVAC tech. Needless to say, I’m forever grateful to your angelic covering during this obstacle.🙏😊

[terrancebyrd]

This guy is definately the best I have seen. He is not annoying and he gets to the point.

Weather lady says a snowstorm is coming. It’s currently 36° and temperatures are dropping. My wife and kids keep saying it’s getting colder and colder. I’m ignoring them and then I start to notice that it is getting colder. I check the thermostat at 68° in the house but the desired temp is on 74. I must say everything that you described in your video between the cycling on and off cutting and then off for three hours to the letter was happening. I went through your entire instruction video with my son and in less than 15 minutes we had the furnace up and running again. I thank you so much. I am a subscriber, liked &commented. I appreciate it. God in your heart, peace in your thoughts and dreams. Job well done ( impressive that this video is 3 years old and still informative and effective)

[GrowBettaBlues]

You just saved me a $75 service call fee and only God knows how much more! I fixed this problem just by following your instructions. Thank you and God bless you!

[trayday]

You are a true life saver...my heater went out on a snowy morning & I have 2 young kids, one only 4 so I was worried about their safety but I watched this video & followed your instructions & just like that my heater is back to business!!! Can't thank you enough, your a true blessing!

[Alawicous]

100% the problem we were having. Woke up to a 50 degree house this morning and had been having some furnace troubles previously but could manually toggle the temp to get it going until today. Nothing would get the furnace to fire and stay lit. Watched the video, went downstairs, 15 minutes later and no money spent we’re back up and running. THANK YOU

[Shotta]

This helped me last night. I've been in my house 1 year. The furnace would turn on and the flame would stay lit for maybe 10 seconds. I cleaned it and it stayed lit for the full cycle. Thank you so much! My house is much warmer now.

[jmlockwood]

This was SO helpful! I am 9 months pregnant and noticed I was getting cold with our heater staying on. Noticed the furnace would ignite and not stay on, so came on here, found your video and it worked! I am now warmed back up and it was so easy to do. Thanks!!!

[ynuscch]

My furnace was doing this very same thing. It was going to be in the low 20’s tonight and it was getting colder in the house. I cleaned the sensor with a one dollar bill I had just like he said. And the furnace is working perfectly now! He knows his stuff! Thank you so much for making this video!!!!

[kozakoutdoors]

Thank you so much!
$8.50 for drill bit extended, $1.00 for cleaning sponge, about 30 minutes of trying to convince my concerned girlfriend that I probably wouldn’t burn the place down, 10 minutes of following your tutorial, and we have heat after being cold the past few days AND saved us a ton of money! Thanks again!

[tobyhayes]

My furnace quit firing yesterday. I watched your video and cleaned the flame sensor. This fixed the problem and the furnace fired and ran properly. Thanks for saving me from an overpriced repair.

[Teedys]

Thank you, I am a single grandma raising my infant grandson and because of your help I was not a victim of an over priced heating salesman/repairman.

[phillipkennedy]

My wife and I are first time home owners and being quarantined to the house with all this Corona virus this video helped us stay warm and save money! Thank you so much!

[arahleegausman]

I’m a 67 Year old woman and this fixed my furnace. Thank You so very much. I’m handy but have never looked in the furnace.

[Godistheanswerministries]

My furnace was experiencing the same problems. But after watching the video and following your instructions. I now have a furnace that is working. Thank You.

[BubbaGooder]

Sweet! My furnace is now WORKING! 8pm with temps of 17, glad I watched this video. Thank You!!! Mine was the flame sensor. Scrubbed it just like you did and now everything is working perfectly!!
