kwkpr- Welcome to iRV2!!

I think you'll need to add some coach specific info (year, mfgr, model...) to attract the attention of folks w/your same coach and furnace system. Maybe also a fuller description of the furnace system you have, whether it ever worked on electric, etc... After that you will probably find a wealth of response.

FYI- using the UserCP feature at upper left you can add your RV data to your "signature" (see mine below- I never have to type that stuff each time I post, as the signature is automatic), along w/some useless, philosophical drivel if you so desire (again, note the editorial comment in my signature).

I am not sure this response applies, but here it is anyway.

The electric Duo Therm on our coach is roof mounted. The heat pump in those units will operate to @40 degree outside temperatures. Any lower, it is not effective. Of course their primary purpose is for Air Conditioning cooling.

The gas furnace is a separate unit on our rig.

If you have both systems in one thermostat controller, perhaps that is where your problem is.

We have separate controls and thermostats for the furnace, and the DuoTherm roof mounted units.

I'm a bit confused. As far as I know, the Sunseeker has a propane furnace and a separate roof air conditioner. The roof a/c may be a heat pump, enabling it to act as a heater as well. They both probably operate off the same thermostat.

Is it the electric heat from the roof a/c that doesn't work?
