Possible Causes

Safety first: Unplug the freezer before accessing the sensor.

Verify with a reliable thermometer: Place it in the center of the freezer away from walls and compare after several hours.
Inspect sensor location: Ensure the NTC sensor is properly clipped to its mounting point and not hanging loose or buried in ice.
Defrost if iced: If the sensor is encased in ice, perform a full manual defrost.
Replace sensor: If readings remain inaccurate, replace the freezer NTC sensor with an OEM part.
