I know it's been a while but here is an uneventful update. Both I and a tech have traced the wiring from battery to board, board to fridge and back and everything seems to have 12 volts running to it. I can bypass the board and the fridge will run. Just changed out the board and no luck, brow board still not showing any power or control. I guess I'll take to another shop and see what they can find. This is very frustrating because there has been no problems to this point. It still acts like a switch or a fuse is off or blown or a wire has come loose as there is nothing, no light in the fridge, nothing. Just likes its unplugged. If anyone else has any ideas before I move to another shop I would appreciate it. Thanks, Tom.
