Is this the right Norcold code list for your fridge?

The code guides on this page use the Norcold 1200-series absorption refrigerator manual. Do not assume they apply to another series or a compressor refrigerator, even when the display looks similar.

How to use this Norcold code list

Copy the letters, spaces, and capitalization shown on the refrigerator display. Codes such as AC LO, DC LO, and NO CO identify different power or cooling conditions.

Confirm the refrigerator model and serial label before acting. The guides below explain safe observations and external checks; they do not replace the service procedure for the exact model.

If a code returns after the owner-manual reset allowance, stop repeating resets. Record the code and operating mode, then use the linked Norcold reference or arrange qualified service.
