I can't figure out what's wrong with my fridge. I think I've narrowed it down to the thermocouple, but I thought I'd describe the problem here to see if anyone has any other ideas. I have a Dometic 3-way fridge in my PUP. When I try to get it to run on gas, it won't light itself and the Check light comes on after a few minutes. I know it's getting gas because I can take the cover off of the burner and light it manually. It works just fine after that. If I blow the flame out, it sparks instantly and relights itself. If I turn it off and let it cool down, it won't light itself again. Am I on the right track with the thermocouple or should I look at something else? Thanks.
