Furnace won’t fire

[Burchie70]

Getting ready for a trip and tried my furnace and it cycles but won’t fire. Propane tanks are full and I also checked the fuse for the thermostat. Its been working fine up till last night. It’s a Jayco Eagle 27.5. Anyone have any ideas where to start looking ? Thanks

Battery or shore power? Fan may not be spinning fast enough for the sail switch to fully close.

I actually tried shore and just the batteries

Did you turn the furnace to off at the thermostat? I had ran out of propane one night, switched tanks manually, and wouldn't refire. I had to turn the thermostat to off and everything worked fine once I turned the heat back on.

Yeah we tried shutting it off then back on. Also unplugged shore and shut battery switch off for 5-10 minutes turned back on and still won’t fire. Stove and fridge light with no problems

See if you have a reset switch on the top of the furnace. Sometimes hard to see without a flashlight. Also try running a stove top burner to verify propane is flowing through the trailer.

I did try running the stove and it worked fine. I also hit the reset button on top of the furnace. Thanks for the ideas guys

Here was my furnace nightmare. Been working fine for 2 years now after the fix.

Sounds like you have done all of the pre-tests. I always turn on the propane stove burners to make sure all of the air is out of the line.. I also check the air vane to be sure it is free moving...

Check the air vane again and make sure it moves the whole distance???

Not much more left to check...

One other thought - Assuming your disconnect switch is on for your ceiling lights... Mine has a foldover switch location where a push button switch is located...

Glad you checking things at home before the trip...
