First blizzard warning in Wisconsin for over 10 years and our furnace decided to stop working this morning. At least I was home because of the weather. Still had to drive a hr round trip in the snow and hope the after market sensor works. It is, for now…
Which part is the flame sensor? Our furnace is getting old, last year I had to replace the exhaust fan pressure sensor. What were the symptoms?
It’s attached to the white wire, top right. Looks like the piece in my hand. One scew holding it in. One electrical connection. And is basically a metal rod with a bit of porcelain insulator.
I got a universal part that I needed to bend to match the one in the furnace.
Symptoms were that it wouldn’t stay lit. It would try, light up for a second and go out. Exhaust fan stay on the whole time.
We got up normal time for work but she had off and I had a snow day. She noticed that it was getting cold in the house so I went to check. The furnace is plugged into an outlet mounted to the side of it’s self. The GFCI was tripped so I reset it. It came to life but just the fan. Then I heard it trying to light and fail a couple times. Looked up some videos about “my furnace won’t stay lit” and they all said start there. Just happened to be the problem.
Ah I see it now! Thanks for the info.
