Wasn't getting 12 volts to the thermostat asnd a temporary jumper form a lite switch fixed the problem for the moment. Furnace seems to want to run, however, intermittently, regardless of whether thermostat is OFF or on heat. A little unclear on the off and reset switch. Off would seem to turn the furnace off but why you would leave it in the reset mode which I am guessing is really the run mode. I have 1 2018 Thor Miramar. Took to dealer several times and no fix. eager to ehar how your problem turned out.

Hi Larry, To answer the question, I'm not quite sure. I live in the North East and haven't had the RV out the last 2 winter months.... but I'm looking forward to a trip coming up. After my last trip, I let the heat run for 24 hours, without having to perform my "Heat Thump". I've also gone out and run it twice during the winter (with moving the RV, and running the generator - just for maintenance purposes) and the heat worked. I spoke with the service Tech from the place where I purchased the RV, we both kind of suspect it is the "Sail Switch" - he is sending a new one out to me since they are relatively cheap and also asked to do some further debugging (measure if the switch is stuck closed) when/if it happens again. Having the spare sail switch with me wont leave me stranded and its a quick swap out.
Your problem sounds a little different since you are able to bypass and provide 12V to the thermostat. I would try and follow the wiring diagram, IF yours is the same as mine, there is a "Reset" switch, on the furnace that FEEDS the thermostat. you may want to check that to see if its lose/triggered or a wire is lose - check the voltages there.
