TROUBLESHOOTING
③ When there is no buzzer sound.
The buzzer is attached to the Panel PBA in this model.
If the buzzer does not sound when you press a key, run the Forced Operating operation or open the door, separate the
Panel PBA and check if the buzzer is broken or improperly soldered.
(If the problem is not an improperly soldered part but a defective part, it is recommended replacing the Panel PBA
because repairing the part is difficult.)
※ Note that the problem may not be identified when the refrigerator is a built-in appliance of the house or the installation
location is very noisy.
