Heater not working

We need help, We have a 2011 Tiffin Open road motorhome. We did have the heat working on electric, Now its not. The living room is blowing cold air, and the bedroom is not blowing at all. We have checked the fuses, and they are fine. We have the switch on electric so even if we were low on propane it wouldnt matter, but we did switch over to propane to see if it would work and still the living room is blowing cold and the bedroom is not blowing at all.Does anyone have any other ideas that we can check

does the thermostat have an automatic setting? If set to "fan" will just blow cold. Just a thought. My 5'er is that way.

Hi Terry,

Did you check the fuse in the thermostat? I think there is a 5 amp fuse behind the cover of the thermostat.

Does the stove have gas? Turn the stove on and see if it will light. If not you might have a problem with the regulator on the propane tank. Tiffin has had some problems with the factory installed ones. Or you could have the same problem I had and the valve wasn't turned back on when I had the tank filled.

What is the temperature outside? The heat pump will only work if the temp is over 40 degrees.

Good luck,

my first guess is fuses...
a fuse that looks good is not always good !!!
swap fuses to make sure...

is it possible the duct got disconnected ?

Is the heat in question here from the ceiling ducts (a/c-heat pump) or a furnace? Propane is irrelevant unless it's a gas furnace, and electric doesn't apply to the furnace - it always runs on LP gas.

Yep, and if it's a heat pump, it won't work below around 40, just blows cool air.
