Freezer displays error code H2 and may not enter fast-freeze mode or may overcool.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Shorted NTC sensor, Sensor touching evaporator directly, Control board misinterpreting sensor data, Wiring short

Safety first: Unplug the freezer before accessing internal components.

Check sensor mounting: Ensure the sensor is mounted as designed and not directly taped to the coldest part of the evaporator unless specified.
Inspect for moisture: Moisture ingress into the sensor connector can cause shorts. Dry and clean connectors if needed.
Replace sensor: If readings are clearly wrong or the sensor is shorted, install a new Ariston NTC sensor.

When to call a technician: If H2 persists, the control board may require professional evaluation.
