What should I do if the door open alarm sounds?
If the freezer or refrigerator doors have been left open for five minutes or more, an alarm will sound and the door open indicator will illuminate on the display. Close the door or press the Clear Alerts button (internal dispenser model) or any key on the display (external dispenser model) to silence the alarm. On the external dispenser model, if the door is open for 5 minutes, the interior light will also turn off.
