1. Did it ever work?
2. Check your breakers, if the fan won't come on, could be power
3. Do you have both gas and electric heat on the thermostat? (Heat Pump)
4. Gas Turned on?

If you can't turn on the fan, then I would search for an electrical problem.

On ours, there used to be a delay once you turn it on... time for propane to flow, time for sensors to indicate heating, etc....

but like Scott said - check breakers - fuses... even if a breaker LOOKS ok, turn them off and back on to make sure !

Sounds like electrical, but to be certain it's not propane,
I would light the cooktop to ensure the gas is flowing and most of the air is out of the system.
(purging the system sometimes took a while for our 38gk, I would light a little bbq starter and hold it by the burner until it started rather than keep clicking the cooktop starter)
Once cooktop does ok, try heater again...

Do you have heat pumps on the roof ac ? do they work? if so, can use them until you resolve furnace issue...

That thermostat has SO many settings, just make sure it is set properly... good luck

If nothing on the furnace runs it's most likely coach battery related. Do your overhead lights or any other 12 volt items work?
