How to turn on 2001 Four winds heat

Look for a switch on the bottom of the thermostat. Depending on thermostat it should be in "heat".
Does the fan start up? If it does, it may take several cycles to clear air from line being replaced by propane.
Is the propane on? Operate stove top to insure you have good propane flow.

Using the stove not only gets propane that far, it confirms propane is flowing. Could be a regulator issue.

Yes check all sides of the thermostat for an On Off button. Also does the furnace have power? Does the overhead lights or the bathroom fan work?

I got it to work but it only works when the generator is on. Is that normal? The fridge also only keeps cool when the generator is running. I used to have a 2013 four winds and the fridge/heat would run without the generator.

Furnace should definitely work on 12v and so should the fridge. Are the lights much brighter with the generator running? Sounds like maybe the battery is too weak to run the furnace.

Are you getting power from the pedestal? Check voltage on the main breaker(s) in the RV breaker panel.

That is not normal!
Refer should be set on "auto" so it will switch from different sources.
Do you have a battery disconnect? It should be "ON".

turned out to be the battery disconnect switch was turned off. Thanks all for the help!!

Thanks for the update!
Don't be afraid to ask questions.

Still seems odd that you only had heat when running the generator. This would happen if the battery was dead or disconnected and the converter that supplies 12 volt power was only powered by the generator.

Battery on or off the heat should still work if plugged in.

I am afraid you might be running just on battery power. That is fine until the battery is dead. Check the voltage on the battery now so you don't lose power in the night. 13.2+ volts you are fine, 12.6 or lower and your time is limited.
