I have a '06 Wildcat and hope this isn't to long. The furnace was not igniting unless you held hand over inlet valve then it would run fine. The thermostat would turn off the furnace.
I took the furnace out and to the shop.They did a bench test, replaced the ignitor and cleaned the unit, all was fine.
I reinstalled the furnace (I have done this fine before) now it will ignite and run and run and run. The burner lights right up, I can here the thermostat clicking for it to go off but the furnace doesn't stop. The burner will go on and off so it is not overheating, I have to take out fuse to turn it off.
I did call the rv shop they said it may be the wiring from the thermostat but it was fine the day before. AC side works fine.
Oh its 22 degrees right now.
