Have an Arctic fox 2018 32a and fridge does not work, even though we had the trailer fully inspected prior to purchase from second party. The panel won’t select gas or auto and shows error code no dE (the top of the E is not showing). We have had mobile repair come and he is unable to get a circuit board anywhere and manufacturer is backlogged and can’t even give us a time when it might be available. Any suggestions? Help getting old living in rv without fridge, but I know it could be worse!
