Door Ajar Alarm Troubleshooting

Beeping With Door Closed

For troubleshooting information for beeping with the door closed, see Sub-Zero Beeping and Silencing Alarm on Classic Series (BI) Refrigeration Product.

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.
