Thanks for the feedback. I was leaning toward the mother board as well. I originally ruled out propane supply as the stovetop lit right up but when I checked the propane bottles, I noticed that the auto-switching propane regulator was on an empty bottle. I now suspect that when the bottle ran out, it would supply a large flow(stovetop) but not the fridge.I switched the supply to the full bottle and have not been able to get it to act up since. Perhaps the autoswitch was not operating properly after the long winter of not being used????
