We had a problem with our Dometic. Looked like it was an issue with the control board. Digital display made no sense. Took it to CW. They were very busy and I waited over two hours. They suggested early on that they thought I must need a new board based on symptoms. $500. I waited some more and the assistant went back to check and confirmed that a new board was needed. It didn't feel right but I authorized the order, put a deposit on it and went home. We were doing some other odds and ends and turned off the main battery switch. When we turned it back on the refrigerator operated normally in all modes. Lesson learned - I don't think there's any way that CW could have disconnected the control board as instructed in some troubleshooting that I'd seen. So, if you haven't turned off all battery power, try that.
