RV Heat Furnace Cycles on three times and shuts off..

My heat in my 2018 Jayco JF 32BHDS with Atwood furnace turns on:
- blower come on
- cycles to fire up
- warm air comes out of the registers
- air turns cooler and fire goes out but blower continues
- it fires up a second time....air gets warmer....same results....air blows cooler but fan stays on
- it fires up a third time....same thing occurs
- after third attempt the system shuts off

It sounds like it starts up...fires up and then something is causing the fire in the furnace to extinguish

I have have all registers open.

What gives?

  • Sounds like the furnace is thinking the burner has failed to light.
    Typically it will try three times then quit.
    I assume you are plugged in with 12+ volts on the battery.

    I would take it back under warranty. Don't monkey too much or it will be your fault.

    so get your bottles repurged bet the oroblem goes away



    Even though it worked 2 months ago when we first took delivery of the rv?

    BUT I have disconnect the main two tanks a few times to install my hitch.

    I will also add that all other gas fed appliances work as well. (oven, outdoor stove, indoor stove & hot water heater/LP)
