I'm having the same problem. My board fuses are fine. The heating element gets hot in AC mode. I hear the relay turn on. My flame lights in GAS mode. But I get no cooling in the freezer or fridge. When I touch the black tubes of the the cooling unit, only the very lowest level tube is hot. I'm thinking its the cooling unit that took a dump. This thing was working very well for a few months since I got my 5th wheel. Then overnight it went out. My refer is a Norcold n811. I'm curious to see what you figure out. I want to make sure its the cooling unit before I replace it becuase its basically the most expensive part by far. Thanks everyone for your replies to this thread so far.
