No Co Norcold | Reset Norcold | No Co | Not Cold

This is because the No Co fault code is set when the fridge does not cool after turning on, the ARP detects this situation and usually intervenes before the No Co fault code can be set. If you do have the No Co turn on, this can be due to the temperature sensor (thermistor) in the fridge not sending a signal to the Norcold controller. Thus, please use this page with the
