Freezer shows E2 and may over-freeze or not freeze properly

Safety: Unplug the freezer before accessing the evaporator area. Edges of metal panels and coils can be sharp; wear cut-resistant gloves.

• Access the evaporator: Remove baskets and inner rear panel inside the freezer compartment to expose the evaporator coil (on no-frost Montpellier models). On chest freezers, the sensor may be embedded near the coil path under the liner.
• Locate the sensor: Look for a small cylindrical or bullet-shaped sensor clipped to the evaporator tubing or housed in a plastic clip.
• Check mounting: Ensure the sensor is firmly clipped to the coil. A loose sensor can cause incorrect readings and trigger E2. Re-clip it securely.
• Inspect wiring: Follow the sensor wires to the harness. Check for ice damage, chafing, or broken insulation. Repair any damaged sections and ensure connectors are fully seated.
• Test the sensor: Measure resistance at room temperature and again after placing the sensor tip in ice water (0–2°C). The resistance should increase significantly in ice water. If it remains unchanged, is open, or shorted, replace the sensor.
• Replace sensor: Fit a Montpellier-compatible evaporator NTC sensor, routing the cable along the original path and away from the defrost heater.

If E2 remains after sensor replacement and wiring checks, the main control board may have a defective sensor input and should be evaluated or replaced by a professional.
