How to Fix / Troubleshooting

Safety: Unplug before accessing sensors or control board.

Steps:

  • 1. Verify with thermometer: Place an independent freezer thermometer inside to confirm actual temperature swings.
  • 2. Check sensor mounting: Ensure the NTC sensor is properly clipped and not hanging in free air or touching the evaporator directly.
  • 3. Replace sensor: If readings are erratic or out of spec, install a new AEG sensor.
  • 4. Usage habits: Minimise door openings and avoid placing hot food directly inside.

If fluctuations persist with a good sensor and proper usage, the control board may require replacement.
