Thanks! After watching 20 videos where everyone just recommends to replace the pressure switch, the genius in this video recommends to just tap on it a bit to see if you can get it to reset if it's stuck open or closed. And it worked!

My heat wouldn’t come on and after searching my furnace and model number, I had found how to read the code. Next I searched the code on KZbin and found this video. I did exactly what the tech said to try and it worked!!!!! Many Thanks to you!!!!! So much appreciated!!!!!

Thank you for this video. This was happening to my furnace. I tapped on the switch and it started right up. Now I’m a hero to my wife.

Thank you! Based on this video, I checked the exhaust pipe and found a dead bird blocking it. Very helpful!

Thanks for this video! Popped a small screwdriver into the furnace end of the rubber hosing and the furnace works again. Now I can sleep without having every blanket on top of me.

Man, this just saved me a whole ton of time and money. Although my switch is different, I disconnected the line going to it and found some moisture there. After carefully drying it out and reconnecting, the system fired right up. Like and subscribed. Cheers!

Good tip about not blowing or pulling vacuum lines so not to damage the switch! 👍

Hi Bro, can i ask question to you, what is the ideal setting pressure for the Low Pressure switch and High Pressure switch to be set in HVAC system for R22. Thanks for your response.

Thank you kind man! 😂 I seriously doubted just tapping it would work but here I am in my warm house just by tapping on the pressure switch! 🤙🏼

Thanks so much I'm working now on a two stage Goodman and when it's going in to second stage it comes up pressure switch stuck closed, interesting that the unit stays running after a while it shuts off, after watching your video I'm going to inspect the tube and I'm going to try to change the pressure switch. Thanks so much, (I like your video you don't drag around like other people you get right to the point good job)

Thank you for this info! I had this issue and discovered a blockage of that ashy residue in the nipple in my draft motor housing. Saved a service call!

[@daniellascaris4533]

Thank you very much for your information. My inducer won't shut off, it keeps running all the time and because of that the system it's not working so what should I do? if I turn off manually the inducer it will restart the system but after the house reach the thermostat temperature it shut down the furnace and the blower and it won't resume anymore until I will do it manually again. Any ideas?

Thanks, great video. I just used this to restore heat to our home. I appreciate the help!

Thanks so much ! Had a walnut stuck in the vent pipe so therefore it couldn’t draft and as soon as I pulled it out it started working !

[@nbansal4732]

Thank you! I whacked the switch with a spoon and it works now! You saved me hundreds of dollars!
