I have a 2012 Keystone Cougar, and have recently had issues with my heater not maintaining the temperature I set the thermostat to. It will turn on initially, but after it reaches that desired temperature, it won't kick back on. I typically have to turn the system off, then back to heat in order to get the furnace going again. If the heater has been running and then stopped running, I can turn the desired temp to max and the furnace still won't kick on. I replaced the analog Coleman Mach thermostat today, (having read a bad thermostat could cause this issue), but no luck. Propane tanks are full, I tried swapping the tanks just in case.
Would appreciate the help, got a one year old I'm trying to keep warm in below freezing temperatures at night. Thanks!
