On a recent outing in our 325BHQS we set up camp as always including of course to extend all the slides. Everything was fine until we noticed water dripping from the ice maker. I could still hear the refrig compressor and feel air blowing into the freezer but it wasn't refrigerating. Gradually everything thawed. When I got home I retracted the refrig slide but left it our about 8 inches hoping there was some rear panel access...how else would you get at the back of the refrig. Bottom line is that I heard ice being made and the whole thing worked again. How do I access the back of the refrigerator and what could be getting pinched off to kill the refrigeration?
