No thermostat power at Atwood furnace
Had the Motorhome out this weekend, in the mountains, and of course the furnace wouldn't start. Its a Thor West Residence Model with an Atwood 8940-IIICLP furnace. I've done enough diagnosis to tell that I am not getting power on the blue wire to trigger the furnace to run. There is power on the red wire so with some jumper magic I can fire the furnace up with all of the safety still in place.
But at the Duo-Therm (Comfort Control) Thermostat I just have an RJ11 telephone cable. The thermostat seems to be working for everything else so where do I look next for the issue? Is there a fuse somewhere or a main control box?
Or is there a way to test the Duo-Therm?
