Hi guys, I need some assistance.
I went and filled up the propane on the rig today and when I got back turned the heaters on to test them out.
The front one turns on just fine and produces heat.
The rear one, however, does not. No fan, no burner.
When I flip the switch to turn it on, I hear a click, presumably from the control box under the fridge.
But the furnace itself isn't doing anything.
The rig is new enough to me that I don't get know where or what to check to make it work.
Any and all assistance is appreciated.

So many possibilities here - does the fan come on? If not, check the DC fuse. Is it blown? Is there 12V on both sides?
If the fuse is OK, get into the heater and see if there is 12V being supplied ot the heater fan (when the fan is called to run)
If there is 12V, but the fan motor does not run, bad fan. If not, trace the wiring to figure out where the 12V stops.

Wiring diagrams for the rig and for the heater would be very helpful, they will help you determine where all the fuses are, and to trace the circuit.

Good luck!

Remove outside cover there is a reset button.
Check fuses

Fan runs but produces no heat .
Propane operators are required to shut off the supply valve before filling ; did it get turned back on ?
Have you tried the stove top burners ?

Two furnaces , in a 36' coach is rare , can you post a picture of the switch your turning on ?
Is the second furnace on a separate thermostat ?

Hey all, not sure why this was resurrected, but I have since removed the rear heater in favor of a Cheap Heat Stand-A-Lone unit.
Thanks for the suggestions tho.
