Door Alarm Tips

The alarm monitors both the refrigerator and freezer door(s) and drawer(s).

Duration and Timing

  • The door ajar alarm sounds after 30 to 60 seconds of the door opening (time varies by product).
  • The amount of time before the alarm sounds is not adjustable.
  • The alarm sounds until the door is closed, or the alarm is turned off on the control panel. Press the Alarm key to turn the alarm off.


  • The door ajar alarm volume is not adjustable on 600 and 700 Series models.
  • For information about other products, refer to Sub-Zero Volume Adjustment.

Bell Icon

  • When the door ajar alarm is on, the bell icon appears in the display panel indicating it is working.
  • When the door ajar alarm is on and the door is left ajar, the alarm icon flashes.
  • When the door ajar alarm is off, the bell icon does not appear in the display panel.


Door Ajar Alarm Troubleshooting

Beeping With Door Closed

For troubleshooting information for beeping with the door closed, see Sub-Zero Beeping.

Door Ajar Icon on But Chime Does Not Sound

  1. If the door ajar alarm icon is on but the chime does not sound, or if the chime has become hard to hear, reset the breaker for 10 seconds.
  2. If the alarm works for only one side, refrigerator or freezer, the alarm is sensing the door switch. If the door is slightly open but the switch is not sensed as open, the alarm may not work.
  3. Opening the door fully and see if alarm turns on after one minute.
  4. If the door ajar icon still appears after the steps above are complete, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
