Our fridge has been working fine until recently. We arrived at our destination and had no digital display and no power. We had a repairman come out. He reset it or something and it still didn't work, but a display of "10" appeared. We left and returned a couple of days later and our fridge was working normally again with a display of 34 degrees. Then we moved to another campground and it stopped working again. Does anyone know where the reset button is? Anyone have this problem?
