Just here in Montana, stove works getting gas failure and below it fan failure when I try to run the

CCC

Alde heat on propane. No electric for now. Lithium power says good.

The manual says to disconnect power to the boiler for 5 minutes. Probably easiest to turn off the battery for 5 minutes (assuming no shore power). AFAIK this is a fan that helps moving hot exhaust gas to the outside. More info here: https://tab-rv.vanillacommunity.com/discussion/5023/alde-fault-message-fan-failure

Agree with @Grumpy_G. Same thing happened to me. Finally figured out to turn off the battery disconnect switch, then turn it back on.The Alde started working again.

I did the same thing but mine still fails.

This Alde has been nothing but annoying disappointment. It has only been used 20 times, so it is not like it is under stress from overuse.
