E2 displayed; ice maker runs briefly then stops, fan may not operate correctly

Safety: Disconnect power before removing any covers.

• Locate ambient sensor: On many Midea ice makers, the ambient or cabinet sensor is mounted near the air intake grille or on the interior liner, with two wires leading back to the control board.
• Visual inspection: Look for cracked sensor housing, moisture intrusion, or broken insulation on the wires. Check that the sensor is firmly clipped in place and not dangling.
• Check connections: Follow the sensor wires to the main PCB. Unplug and replug the connector several times to ensure a good contact. Look for corrosion or bent pins.
• Test resistance: With the unit unplugged, disconnect the sensor and measure resistance. Compare to the service manual chart if available; if resistance is extremely low (near 0 Ω) or infinite (OL), the sensor is defective.
• Replace sensor: Install a new Midea-compatible ambient/cabinet thermistor. Route the harness along the original path and avoid pinching it when reinstalling panels.
• Board check: If a known-good sensor still triggers E2, the main control board may be misreading the sensor and should be replaced by a technician.
