Freezer shows E2 and may run continuously or not cool correctly

Safety warning: Always unplug the freezer before removing internal panels. Evaporator fins are sharp; wear cut‑resistant gloves.

Steps to diagnose and fix E2:

• 1. Defrost and access evaporator: Remove drawers and internal rear panel inside the freezer to expose the evaporator. If iced over, allow to defrost fully (use towels; do not chip ice with sharp tools).
• 2. Locate the evaporator NTC: It is usually clipped to the evaporator tubing or embedded in a small plastic holder attached to the coil.
• 3. Visual inspection: Check that the sensor is firmly attached to the coil and that its cable is not cut, crushed, or corroded. Ensure the connector at the PCB is fully seated.
• 4. Electrical test: With the freezer unplugged, disconnect the sensor and measure resistance. Compare to expected NTC values (similar to cabinet sensor). An open or shorted reading indicates a bad sensor.
• 5. Replace the evaporator sensor: Unclip the old sensor, route the new one along the same path, and secure it to the evaporator coil in the same position to ensure accurate defrost and temperature control.
• 6. Reassemble and test: Refit the internal panel, restore power, and monitor if E2 clears and the freezer reaches the set temperature.
• 7. PCB check: If the sensor and wiring are good but E2 remains, the main control PCB may be defective and require replacement.

Note: Incorrect evaporator sensor readings can cause excessive icing or poor cooling, so address E2 promptly.
