Help w/ heater

[firedreamer2]

We have 2017 Solitude 369RL and have been FT for 5+ yrs now without any problems. Last night i turned the heater on and it ran for about 3-5 min or so blowing just cold air then shut off. Didn't investigate it at the time and it did the same thing this morning. Full propane tanks , stove and burners work fine. The thermostat does also work the ac fine. Any first things to think about/check? Thanks

Have you tried turning the thermostat to off and then back to heat?

Do you hear clicking sounds by the furnace when you try to turn it on (need to be outside by the furnace to hear it)?

Are you on shore power or battery power?

Could be a potential bad sail switch.

I was , am on battery power but will run gen and try and also go out to listen for the ignighter in the next hr or so

If on battery, and voltage is too low, it might not allow the fan to spin fast enough to close the sail switch. I'd see how it operates on shore power or a generator.

Possibly a failed sail switch

When is the last time you ran it?

Could be air in the line, and the safety cutoff is turning it off because there is no propane there.
