Freezer displays E2 and may run continuously or not cool correctly

Safety first: Disconnect power before removing any panels or touching wiring. Wear cut-resistant gloves when working near metal fins.

Steps to address E2:

• Access the evaporator area: Empty the freezer section as needed. Remove the inner rear panel or evaporator cover (often held by Phillips screws). Carefully pull the panel forward to expose the evaporator coil.
• Locate the sensor: The evaporator NTC is typically clipped to the evaporator tubing or embedded in a small plastic housing attached to the coil.
• Visual inspection: Check for broken wires, loose connectors, or corrosion. Look for signs of ice buildup around the sensor that may have stressed the wiring.
• Test the sensor: Disconnect the sensor from its connector. Measure resistance with a multimeter. Compare to expected NTC values (commonly 5–10 kΩ at 25°C; resistance increases as temperature drops). A reading of 0 Ω or OL indicates failure.
• Replace the sensor: If readings are abnormal, install a new Midea evaporator NTC sensor. Clip it firmly to the same location on the coil to ensure accurate temperature sensing. Do not pierce tubing.
• Reassemble and test: Reinstall the evaporator cover, restore power, and monitor if E2 clears after a few minutes of operation.

Note: If the sensor tests good but E2 persists, the main control board may not be reading the sensor correctly and could require replacement by a technician.
