Furnace Repair - FYI
My 1998 Ford E250 SMB was built with the Suburban furnace system. I've had the camper for 18 months but had never used the heater until our trip to Wyoming in September and it worked great for a few cold mornings in the Wind River Mountains.
Then, one morning it didn't work. I assumed it was either a clogged burner from running it at 10,000'+ or disconnected wiring from all the washboard roads we had driven on. I figured I'd get it fixed when we got back home.
Well, I recently had a mechanic look at it and lo and behold the bimetal spring had somehow gotten bound up. The mechanic flicked it and the furnace kicked on. he told me the next time that happens, remove the thermostat cover, flick the coil and it should be good.
I hope this helps someone.
