Take down the fan cover and fan motor, check whether the connector of defrost sensor is in right
position; ensure the wire connector is in good connecting status.
2.Disconnect the connector, test the resistance between two black wires, the normal resistance should be
1～30K ohm approximately, if the ohm number is infinite or zero, it means that the sensor is defective.
If the sensor is normal, reconnect the connector.
