The electric part of our Dometic frig has quit working. It cools fine on propane. But will not switch over to electricity when plugged in. What should I check first? Thanks in advance!
There is a fuse for the 120 AC element and a fuse for the refer optional 12 volt. If in auto and it immediately switches back to LP, there is no 120 volt. If it stays on 120, it could be the circuit board or the element.
