refrigerator problems
Not really odd in some ways. Electronics have always had the reputation of
failing do to heat. Though todays electronics are less sensitive some "parts" can be and fail. You more than likely have a Dometic board installed and they are "potted" other wise I would suggest waiting until night the take the wifes hair drier out there and apply heat and see if it changes. You have a relay on that board that is heat sensitive or a triac that is heat sensitive. I remember when nixi tubes would heat up the "fire" spurious things would really happen then,, oops nixi tubes, am I dating my self or what?
