HELP!! Furnace won't work

[Bayley]

I'm in Bryce Canyon and during the night my furnace stopped working.

The thermostat is working but the blower only comes on and blows cold air for about 30 seconds and then stops.

I have checked the propane and all is good.

Is there anything I can do to get the system running again? It's COLD up here.

Thanks for any help!!

If your stove top is burning you can sort of rule out frozen propane lines feeding trailer.

Assuming your 12VDC is all working ok. i.e. Ceiling lights ok...

The BLOWER FAN has a sail that get sucked in when the blower start up. That keeps the propane value open. Might check to see if that is working...

Hope you brought along alternate heat for PLAN B

Are you operating on shore power or batteries? If on batteries they could be low not allowing the fan motor to spin fast enough to close the sail switch.
Operating on shore power, the sail switch could be not closing. A can of compressed air could blow the debris out of sail switch.
Make and model of furnace?
