2011 318BHS Furnace Not Working At All

Hello all!

My 318's furnace is not working at all. You can set the thermostat on heat and 90* and hear the relay in the overhead "A/C" unit/Thermostat click. I have the dometic digital single zone t-stat.

The furnace will not run at all. No blower, nothing. I checked all the fuses in the camper just to be sure, all are good. Propane is on as all other propane appliances work.

I have tried to locate a decent wiring diagram with wire colors, but cannot locate a good one. I'd like to verify at the A/C unit/Thermostat that 12V is applied to the furnace circuit, then move down the line to the furnace itself.

Lastly, are the connections to the furnace accessible from the outside cover, or will I need to remove more than just the large cover outside?

If anyone can point me in the right direction, I would appreciate it.

I am not an expert but it sounds like you have a power problem. First easy check would be fuse/breaker. Past that, I think you will have to get into the furnace.
