First times using the Atwood furnace in our 2019 372rd. It runs for 3 minutes, warm air, then the fire shuts off. The blower continues a minute or so more I guess to cool it down. I read another post about thermostat wires under a dome but I havenít found that I have it. It is very consistent at 3 minutes so I donít think it could be the getting warm and shutting off. Any suggestions?
