Possible Causes

Faulty NTC temperature sensor reading too warm, Stuck relay on main control board, Miscalibrated control electronics

How to Fix / Troubleshooting

Safety first: Unplug the freezer before accessing sensors or the control board.

Steps:

  • Verify settings: Confirm the set temperature is appropriate (e.g., -18°C) and that SuperFrost is not permanently enabled.
  • Sensor placement: Ensure no large packages are pressing directly against the interior sensor housing, which can cause false readings.
  • Reset control: Disconnect power for 10 minutes, then restore and reprogram the desired temperature.

Remedy: If overcooling persists, the freezer compartment NTC sensor or main control board may be faulty. Replace the sensor first as it is simpler and less costly; if the issue remains, the control board may need replacement.
