TEST MODE

The test mode allows checking the PCB and the functions as well as determining
the defective part. Enter the TEST MODE by pressing FRZ and LOCK on the
control panel or by pressing the TEST SWITCH on the main board. In TEST
MODE, the control buttons are deactivated but the buzzer still sounds a ding. To
exit the TEST MODE, unplug the refrigerator for one minute. If a malfunction,
such as a sensor failure, is detected in the TEST MODE, the TEST MODE is
cleared and the error code is displayed.
