I didn't get to work on the heater today, had a doc appt. and Medicare Advantage insurance meeting. Then it was come home and get prepared for the blizzard. Damm I can't keep my mind off losing Kenny.
Anyway, that picture of the heater was when it was new in 2018. I'm afraid none of the creative fuse options will fit!

Those doggone things are about $1.60 each at Ace Hardware! Should be about 30 cents each!
This is what the furnace looks like right now.

I don't have much of a mouse problem here, Jim. Things are pretty clean in the circuit board and gas control valve area.

That vacuum hose that is disconnected was my doing. Testing that diaphragm switch it runs up to. I couldn't hear it clicking so I took the diaphragm out and put a ohm meter on the switch, gave it light suction and the switch does seem to operate. Did that last night.
Found a schematic on the internet of how to test where the problem might be so hopefully will narrow it down soon.
