Temperature Sensor
The temperature sensor is provided on the front head. When the compressor becomes abnormally hot because of shortage of the refrigerant, etc., the magnetic clutch is caused to disengage to stop the compressor for protection. When the temperature in the compressor falls, a reset is made to let the compressor resume operation.
