Possible Causes
Faulty thermostat or temperature sensor, Poor sensor placement, Control board hysteresis issues, Frequent door openings in warm environment
How to Fix / Troubleshooting
Safety: Unplug before accessing sensors or controls.
Steps:
- 1. Use a thermometer: Place a reliable thermometer inside and log temperature over 24 hours to confirm fluctuations.
- 2. Check sensor location: Ensure the freezer sensor is not touching the evaporator or directly in the air stream from the fan; it should sense average cabinet temperature.
- 3. Replace sensor: If readings are erratic, replace the "Amica Freezer NTC Temperature Sensor".
- 4. Thermostat models: Replace the mechanical thermostat if the compressor cycles unpredictably relative to dial settings.
- 5. Control board: Persistent instability after sensor/thermostat replacement may indicate a faulty main control board.
Tip: Avoid placing hot items directly against the sensor area.
