Freezer cycles on and off very frequently (short cycling).

Safety first: Unplug the freezer before adjusting sensors.

Steps:

• Check sensor mounting: Ensure the freezer NTC sensor is firmly attached where the manufacturer intended, not dangling in the airflow.
• Avoid blocking vents: Do not place food directly in front of air outlets or in contact with the sensor area.
• Ambient conditions: Ensure the freezer is not installed next to heat sources (ovens, radiators) and that room temperature is within the specified range.
• Sensor replacement: If the sensor is unstable or intermittent, replace it with a new Grundig NTC sensor.
