If it is working on propane, but not electric, as stated above, it is either the circuit board, the heating element, or possible a small glass fuse on the circuit board. I hate to say it, but your best bet may be to stay away from camping world and either have hubby fix it or find a small, private RV repair service to do it. It's not really difficult. Everything can be done through the outside access door on the side of your RV. There are even videos on youtube showing how to do it. If he has any questions, tell him to take some photos of the rear of the fridge, post them here and ask questions.
