We have a 2011 Montana with a Norcold N811 refrigerator. We are having a few issues with ours so I've been doing a lot of investigating as well. We do have power, but it will randomly quit working.

If your light on the switch panel is not work, but you have power to the plug at the fridge I would unplug the fridge then pull the cover off the control box on the back of fridge. There are two screws holding it on. There are two fuses on the circuit board. One is the glass tube style and the other is the blade style. Check both of those. Also be sure all of the plugs and wires to the circuit board are tight/secure. Also look for burnt or broken solder joints on the board.
On the inside to access the back of the switch panel. I had to remove one screws for the cover on the right, then two screws to remove the switch panel. You can make sure the plug to it is tight and check to see if anything on the circuit board looks burnt or broken.
