RV Repair: propane furnace problems, propane furnace, furnace problems

Question
I have a 2003 Rexair class A with a Suburban SF-35F propane furnace. After arriving at anRV park and setting up, the furnace will come on at the low set point, shut down when it reaches the hi set point, not to come on again during our trip. We replaced the circuit board thermostat after the first failure. This is the second trip it has failed us on the new thermostat.
the propane tank is 3/4 full, the hot water heater produces hot water, and the 3 burner stove operates properly with a blue flame.
The manufacture claims not to have had this issue come up.
What do you recommend for a home fix?
Thankx

Answer

Hey George,
I dont have a specific answer to your question. However it may be a problem with the high limit switch on the furnace itself.Below is the website for the manufacturer of that unit. They have a very cortious
tech assistance staff if you need to call them.
Best of luck,
Jim
