Possible Causes

Door switch not detecting closed position, Sensor reading slightly out of range, Control board alarm logic fault, Previous high-temp event not cleared

How to Fix / Troubleshooting

Safety first: No live electrical work is needed for basic checks; unplug if accessing switches or boards.

Steps:

  • Door switch test: Press the door switch manually with the door open. If the alarm stops, adjust or replace the switch.
  • Power reset: Unplug the unit for 5–10 minutes to clear any latched alarm state.
  • Check sensors: Verify that cabinet temperatures are within normal range using a thermometer. Inspect sensor connections if readings are borderline.

Repair: Replace a faulty door switch or misreading sensor. If the alarm persists with normal temperatures and good components, the main control board may need replacement.
