Heater Fires and runs then cycles before shutting down
I am new to the RV world, I just purchased a 2019 Montana 3854BR 20th Anniversary Edition 5th wheel. I am having problems with the heater. It runs and heats pretty good some of the time, other times it run and shuts off, runs and then shuts off. Sometimes it runs and heats well, then it sounds like it is trying to cycle but won't shut down completely. When it does this the fan is trying to blow, but the furnace is not fired up. I have replaced the thermostat, and the circuit broad and it is still doing it. Any ideas would be welcomed, as some times it won't even kick on and it is cold in the trailer when I get home from work at 8 AM. Thanks in advance.
