I have a 2004 with a Dometic fridge. It quit running on electric. That almost never happens. . . it's usually the other way around. Works great on gas, though. So I took it to the Amish and they tested everything. The fridge actually does run on electric, but not through the plug it's plugged into. So I had my electrical engineer friend put in a new outlet. The old outlet was one of the really cheap trailer receptacles that are a press fit and the wires were just not making good contact. Now it works great. My friend charged me nothing for labor and the parts were $1.87.
