Detailed questions about furnace
Ok, I am puzzled. I began this DIY project on my Bryant 373lav because when a call for heat was placed, the the inducer motor would start and the igniter would glow but no propane would be released by the gas valve. A test of the gas valve revealed no voltage.
The manual states I need a new control board, fine, done.
New control board installed (this one has the led diagnostic feature.) led 3 slow, 3 fast then swapping over to 1 slow and 3 fast, Flame Rollout Switch. All sensors test good for ohms, circuits closed but no there is no voltage when the unit is plugged in. Further, the fan begins blowing and does not stop until the unit is unplugged (I understand the reason for this.)
I also jumped each and everyone of them but could not identify which might be bad. I also jumped all of them at the same time, still the led flashes.
I am just a DIY kind of guy, certainly not a pro but know my way around most stuff but this one is kicking my A$$.
