My Edgestar stays in my garage running on AC while not being used for camping. I noticed it had turned off the other day. I could get it going again on 110v or 12v, but shaking the power cord caused it to stop. Figured it was likely loose connections and finally took it apart today. I can't say for sure what fixed it since some of the connections did seem a bit loose. (I tightened down some of the screws holding the ring terminals and made a better/tighter connection with one of the spade connectors. But I think the actual problem was the back of the circuit board coming into contact with the case. The only insulation between the circuit board and the aluminum case inside the fridge that holds the "brains" of it, is a thin piece of clear plastic. The metal tangs from the terminals go through the circuit board, where they are soldered. This leaves a somewhat sharp piece of metal protruding through the back of the circuit board with only that thin piece of plastic keeping it from contacting the aluminum case holding the circuit board. My assumption is that through a couple years of vibration, that tang wore through the plastic and was shorting to the case. (Yes, I should have taken pics, but hopefully this description will help somebody). The ideal solution would involve removing that circuit board and trimming the tangs and then adding better insulation. But my (easy) solution, was just to slide a layer of heat shrink between the existing plastic barrier and the aluminum case.
Edit: Here's a pics from the previous page, but it shows the area I'm talking about where the circuit board is close to the case.
