I would suggest you take a really close look at the 120v power and where it connect to the refrigerator outlet and possible the connections where the slide connects to the main coach. It sounds like the outlet behind the refrigerator doesn't have power at it some time. The power goes into the control board then the control decides if its set to 120v power or swaps over to 12vdc / LP for cooling to start. Does the stove have any 120v power on it? they could have run the power through one outlet to the next and had a bad connection at the stove ?????
