Atwood furnace only runs 3 minutes

First times using the Atwood furnace in our 2019 372rd. It runs for 3 minutes, warm air, then the fire shuts off. The blower continues a minute or so more I guess to cool it down. I read another post about thermostat wires under a dome but I havenít found that I have it. It is very consistent at 3 minutes so I donít think it could be the getting warm and shutting off. Any suggestions?

Have you set your thermostat to a higher temperature to see if it stays on longer?

Could be a bad thermocouple. Sometimes they act like this. I had a fireplace that would stay lit for 5-10 minutes then cut off. Super frustrating. Finally figured out that the thermocouple wasn't quite in the flame enough.

Start with the self resetting fuse (funny looking black one) in your fuse panel.
Notoriously unreliable.
You can swap it with a regular 15A blue one for troubleshooting. In mine there is a couple of spares at the end of the row.
The blue ones have thinner blades. You may need to give the blades a little twist to make good contact.

If nothing else works Atwood knows that they have a bunch of bad sail switches out there and isn't issuing a recal or even a service bulletin.

you should be still under warranty, get to a dealer that would be the best bet right now.
