I am plugged into 120v house current, everything seems to work OK. When I am on Gas though, the burner stays on for an hour or two then the check light goes on. I have posted about this in the past, I have disassembled the pilot and burner and cleaned the thermocouple, as suggested. I have not yet disassembled the flue. When I first got the camper, on the way home, some think dark brown liquid was dripping pretty badly from the fridge access door outside. This ended quickly and I contributed that to a puddle of rusty water that had collected somewhere. My camper sat for almost a year at the dealership. I have not seen this rusty water again, nor can I tell where it had collected. The fridge seemed to work OK when I first got it. I am leaving this Thursday for Utah on Vacation, Should I replace the thermocouple? or any other service I can perform myself? I dont want to take it to the dealer for fridge service, but I think I might have to, I don't want problems with it, while on the road. Can you guys help at all?
