Freezer shows E2 and may run continuously or not reach the set temperature; frost pattern on evaporator looks uneven.

Safety first: Unplug the freezer before removing any internal panels. Edges of metal panels and evaporator fins can be sharp—wear cut-resistant gloves.

• Access the evaporator: Remove baskets and the rear inner panel of the freezer compartment to expose the evaporator coil (often held by a few screws or clips).
• Locate the sensor: The evaporator NTC is usually clipped to the evaporator tubing or embedded in a small plastic housing attached to the coil.
• Check mounting: Ensure the sensor is firmly clipped to the coil. A loose sensor can misread temperature and trigger E2. Reclip or secure it if it has fallen away.
• Inspect wiring: Follow the sensor wires back toward the cabinet and main PCB. Look for chafing where the harness passes through metal openings. Repair minor insulation damage with high-quality electrical tape; replace the harness if conductors are exposed or broken.
• Test the sensor: Disconnect the sensor and measure resistance with a multimeter. Compare to expected NTC values (commonly 5–30 kΩ in the sub-zero range). An open or shorted reading indicates a bad sensor.
• Replace the sensor: If faulty, install a new evaporator NTC temperature sensor. Clip it securely to the same location on the coil to ensure accurate readings.
• Reassemble and defrost: If heavy ice is present, allow the evaporator to fully defrost before reassembly. Then restore power and verify that E2 clears and the unit cycles normally.

Note: If the sensor and wiring are good but E2 remains, the main control board may require replacement by a qualified technician.
