USER INTERFACE FAILURE FEEDBACK

The User Interface can display several failure codes. The display will only show the code(s) for 10 minutes, then revert back to the set temperature(s). To access these codes again, disconnect power to the refrigerator for 10 seconds and then power it up again. It may take 3 minutes for the error code(s) to display. The following table summarizes these codes.
