Norcold 982, 983, 962, 963 manual Diagnostics, Diagnostic Codes and Their Meaning

Diagnostic Codes

The refrigerator’s operating controls are equipped with a diagnostic system which alerts the user to a problem in any mode of operation. When a prob- lem occurs within a given mode, the operating con- trols will revert to a stand-by mode in which an alarm will sound and a diagnostic code will be displayed in thecenter control window. The alarm will sound until an alternate operating mode is selected. The diag- nostic code will continue to be displayed until the controls are turned "OFF" and then back"ON". If a problem occurs, refer to Table 1 "Diagnostic codes and Their Meanings" on page 10.
