Door Alarm Tips

The door ajar alarm sounds when a door or drawer is open for a set period of time.

  • On PRO3650 and PRO4850 products, the door ajar alarm is adjustable for volume, pitch, and duration before the alarm sounds.
  • It is not possible to silence the alarm but it can be turned off completely.

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

  • When activated, the door alarm shows a bell icon on the display panel.
  • The appearance of the bell icon changes on the control panel depending on how the door alarm set:
    • When the door ajar alarm is turned on, the bell icon darkens.
    • When the door ajar alarm is on and activated (door was left ajar), the bell icon flashes.
    • When the door ajar alarm is turned off, the bell icon appears as light gray, depending on display contrast setting.

Adjust Volume, Pitch, Duration of Alarm

Adjust the amount of time before the alarm sounds under the settings menu. The range is between 5 and 90 seconds. To adjust the volume on a Professional series unit:

  1. Touch and hold the Automatic Display Lock icon  for 3 seconds.
  2. Tap the gear icon  to open the Settings menu.

  3. Tap the Alarm icon  to open the door alarm settings. Tap the alarm icon turn the door and drawer alarm on or off.
  4. Tap the alarm delay time to adjust the number of seconds before the alarm sounds. Tap the + or - icon to adjust the alarm duration between 5 and 90 seconds.
  5. Tap the Return icon  to return to the Door and Drawer Alarm screen, or wait 10 seconds to return to the Settings screen.

Door Ajar Alarm Troubleshooting

If the door ajar alarm is sounding and the door or drawer is closed, something is blocking the door from closing.

  1. Refer to Door Will Not Close for suggestions.
  2. If the alarm does not stop, check the door switch found at the top of the cabinet above the door handle, as it may not be closing properly.
  3. If the alarm works for just the refrigerator or just the freezer, the alarm is sensing the door switch.
  4. If the door is slightly open but the switch is not sensed as open, the alarm may not work. Verify the door is closed.
  5. Open the door fully to see if the alarm turns on after set period of time.
  6. If the bell icon is turned on but the chime does not sound, or if the chime has become hard to hear, reset the breaker for 10 seconds.
