Possible Causes

Faulty temperature sensor, Stuck door switch, Control module logic fault, Alarm buzzer malfunction

Safety: Unplug the freezer before accessing sensors or control electronics.

Steps:

1. Confirm temperature: Use a thermometer to verify that the freezer is at the correct temperature.
2. Check door switch: Ensure the door switch operates correctly and is not stuck in the open position.
3. Sensor test: Test the freezer NTC sensor and replace if readings are incorrect.
4. Control reset: Perform a power reset by unplugging for 10 minutes. If the alarm returns without cause, the control module may be faulty and require replacement.
