Inspect NTC

1. Open the protecting box and take out PCB;
2. With the door closed,unplug the RE connector (shown in below picture), then use the multi-meter Ω shelf to test resistance
between two blue wires (RE and GND), the normal resistance is shown in below table.
3. If the resistance is not correct, it means NTC circuit has a problem. In this case, we should check the connection first. If the
problem hasn't been solved by re-connection, we would replace the NTC.
