Norcold makes small refrigerators that are commonly found in RVs and boats. When the refrigerator is showing a "No Cooling" error code the unit must be repaired. There could be any number of reasons for the code to appear. When the repair is finished, the last step is to reset a Norcold control board to clear the error. If this is not the first time the error code has occurred, the process to reset a Norcold control board is more involved.
