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
the center 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.
