Awesome my freind. I love the way you explained what you were doing. I’ve done hvac for many years but where I live I don’t get to work on to many gas furnaces not a lot of practice. It’s mostly heat pumps
Ps lol you remind me of myself. I diagnosed a bad module on a furnace one time and it was an expensive one so you want to be rite. I sound like you did when you said please work lol Mine, but I had I’m trying to think, a loose ground or something and it worried me for awhile until I got it going.
My furnace stops working overnight so every morning I have to get up early and switch it on and off about 6 or 7 times (Fan comes on but no heat) before the heat finally starts. It works fine all day though. I went up to the furnace on the roof and checked everything. I cleaned the flame sensor and when I start the furnace I can see the spark in the ignitor and then the furnace shuts off. Could you tell me what the problem could be?

I like the diagram after, straightforward and direct!
Gotta love Microsoft Paint!
nice, thank
Excellent video. How can you bench test the ignitor?
Thank you
I would never claim to be a super tech, but it seems they fail often? Great video

At the beginning of your video you said it was counterproductive to check to see if it's calling for heat. That's not counterproductive at all
I think it's because the induce draft motor was on. That should only happen if the was a call for heat in the first place.
Gas valve energize after few seconds no matter what after spark ignition but flame should be proven by flame sensor.
Does the blower run the whole time with this issue?
Good yob.
