Display shows E2 and freezer runs continuously or cycles erratically; temperature reading seems incorrect.

Safety: Disconnect the appliance from mains before removing covers.

• Confirm model type: On some Zanussi freezers (especially combined fridge-freezers), E2 refers to the cabinet or fridge sensor that influences freezer operation. Check the user manual or rating plate for model-specific meaning.
• Access the sensor: The cabinet/ambient sensor is often behind a small plastic cover inside the fridge section or near the air duct between fridge and freezer. On freezer-only models, it may be behind the liner near the top.
• Visual inspection: Check for moisture ingress, cracked sensor housing, or damaged wires. Ensure the connector is fully seated.
• Measure resistance: Use a multimeter to measure the NTC resistance at room temperature (around 20–25°C). Compare with Zanussi specifications. A reading of 0 Ω or infinite resistance indicates failure.
• Replace sensor: If out of spec, install a new cabinet/ambient temperature sensor (NTC). Route wiring as original and avoid crushing it when refitting panels.
• Check control PCB: If the sensor and wiring are correct, the main control PCB may be faulty. Inspect for burn marks or swollen components; replacement is typically the remedy.

After replacement, reconnect power and allow several hours for temperatures to stabilize and the error to clear.
