The Power Outage indicator
Is the door open?
The Door Ajar Alarm feature sounds an alarm when the refrigerator door(s) or freezer drawer is open for 5 minutes and cooling is turned on. The alarm will repeat every 2 minutes. Close all doors and drawers to turn it off.
NOTE: To mute the audible alarm while keeping the doors open, such as while cleaning the inside of the refrigerator, touch any button on the control panel. The alarm sound will be temporarily turned off, but the Door Ajar icon will still be displayed on the dispenser control panel.
