furnace fan
Put my fifth wheel away for the winter and the furnace fan won't shut off. No propane on, just battery. Any ideas what the cause might be?

What the problem is is a laundry list.. What the SOLUTION list (During storage) is much shorter.
Option 1: Remove outside cover and if it's an Atwood furnace on top of the blower housing is what looks like a switch (it is a circuit breaker) Switch it OFF. Of course now the furnace is non-op till you turn it on.
Option 2: disconnect battery .. Physically lift the negative lead off the battery. (This also disables charging)
The laundry list OEM atwood board.
Bad T-Stat likely won't do it. same for T-stat wirings
Bad relay on control board
Bad other on control board
Short on control board wiring.
NOTE: There are two different patterns if lighting fails. Atwood shuts off fully and goes through the entire restart process.. Dinosaur board does NOT kill the blower.. SO if you have a dino board
Add the T-Stat and the T-Stat wires to the suspect list.
