Display shows E2 and freezer temperature is incorrect or unit runs continuously.

Safety First: Unplug the refrigerator before removing freezer panels.

Steps:

• Access the freezer sensor: Remove freezer shelves and the rear interior panel (evaporator cover). The freezer thermistor is typically clipped to the evaporator tubing or mounted on the rear wall.
• Inspect sensor and clip: Check that the thermistor is firmly clipped in place and not dangling or encased in heavy ice. Look for damaged insulation or broken wires.
• Defrost if iced over: If the sensor is buried in ice, defrost the evaporator using a hair dryer on low, keeping it moving and at a safe distance to avoid melting plastic.
• Check resistance: With the unit unplugged, disconnect the thermistor and measure resistance. Compare to expected NTC values (e.g., higher resistance at colder temperatures). A reading of 0 ohms or infinite indicates failure.
• Replace if needed: Install a new Midea freezer thermistor, secure it to the evaporator or wall as originally installed, and reconnect the harness.
• Reassemble and test: Reinstall the evaporator cover, restore power, and monitor freezer temperature and error code status.
