Freezer shows E2 and may over-freeze or not maintain stable temperature; display temperature may be inaccurate.

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

• 1. Access the evaporator compartment: Remove freezer drawers and the rear inner panel to expose the evaporator (often behind a plastic cover held by screws or clips).
• 2. Locate the evaporator NTC: The sensor is usually clipped to the evaporator tubing or embedded in a small plastic holder attached to the coil.
• 3. Visual inspection: Check if the sensor has come loose from the coil or is encased in heavy ice. Look for damaged insulation or broken wires.
• 4. Defrost if iced over: If the evaporator is heavily iced, allow it to fully defrost (leave unplugged with doors open and towels in place, or use a hair dryer on low at a safe distance—do not overheat plastic parts).
• 5. Electrical test: Disconnect the sensor and measure resistance with a multimeter. Compare to expected NTC values for your model. A reading of 0 Ω or OL indicates a failed sensor.
• 6. Replace or reseat: If resistance is out of spec, replace the evaporator NTC. Ensure it is firmly clipped to the coil in the same position as the original for accurate temperature sensing.
• 7. Reassemble and test: Refit the evaporator cover and drawers, restore power, and verify that E2 clears and the freezer cools normally.

Note: Persistent E2 with a known-good sensor suggests a main control board fault that should be evaluated by a professional.
