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 problem occurs within a given mode, the operating controls will revert to a stand-by mode in which an alarm will sound and a diagnostic code will be displayed in thecenter controlwindow.The alarm will sound until an alternate operating mode is selected. The diagnostic 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.
