Don't worry, this is a simple fix! This issue can be caused by one of two parts. The most common part is the Thermistor and the other part that could cause this is your Optical Control Board.
Norcold refrigerators have a Thermistor in them which is combination thermostat/ resistor. It connects to your light fixture inside the refrigerator compartment with a 4-prong connector. Turn the temperature setting to somewhere in the middle and disconnect the Thermistor. If the refrigerator starts warming up and maintains a good level of cool, then we know that the Thermistor has failed.
If after you disconnect the Thermistor the refrigerator continues to freeze everything, you will need to replace the Optical Control Board (board in the front of the refrigerator).
