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.
The best way to determine CU is to hot wire the 120 element for 24 hours. This bypasses the controls. IF the Refer does not get below 38 degrees, the CU is bad. DO NOT run more than 24 hours in hot wire. Doug
