Freezer is too warm or too cold and display shows E2

Safety first: Unplug the refrigerator before removing freezer panels.

Steps:

• Access the freezer sensor: Remove baskets or shelves. The sensor is usually clipped to the rear wall or evaporator cover behind a small plastic housing.
• Check mounting: Ensure the sensor is firmly clipped in place and not dangling or buried in ice. A sensor not in the airflow can misread temperature.
• Inspect wiring: Look for cuts, crushed sections, or ice damage on the sensor wires. Gently free any wires trapped in panels.
• Test the sensor: Disconnect the sensor and measure resistance with a multimeter. Compare to expected values for the approximate freezer temperature (e.g., at -18°C / 0°F, many NTC sensors read 20–40 kΩ). A reading of 0 Ω or infinite indicates failure.
• Replace if needed: Install a new freezer thermistor if readings are out of range or if the sensor is physically damaged. Reassemble panels carefully to avoid pinching wires.

Tip: After repair, avoid overpacking the freezer so air can circulate around the sensor.
