Hello.
We own a 2019 Thor Freedom Elite, purchased used, early this year.
Our furnace is not functioning properly.
It seems that when the propane attempts to ignite something is preventing it. The fan is working, we hear about a 3 second “roar” and then it stops. This cycle repeats every 15 seconds.
We removed the external cover to check for loose wires and hit the reset button, no change. We have plenty of propane.
The issue appears to be with propane vs. electrical.
Any suggestions for troubleshooting?

Sounds like it is not sensing the flame and shuts down/recycles. I'm not sure if this is the same component as the igniter or separate (same in Atwood/Dometic). Check your manual. It may also be a failed control board, but that's a much more expensive firing of the parts canon.

Flame sensor. That was it under exactly same symptoms on mine. It is held in by 3/4 screws and accessible from outside the RV. Videos online on how to replace it.
