4-3 OLP (OVERLOAD PROTECTOR)

4-3-1 Definition of OLP
(1) OLP (OVERLOAD PROTECTOR) is attached to the
compressor and protects the motor by opening the
circuit to the motor if the temperature rises and
activating the bimetal spring in the OLP.
(2) When high current flows to the compressor motor, the
bimetal works by heating the heater inside the OLP, and
the OLP protects the motor by cutting off the current
flowing to the compressor motor.
4-3-2 Role of the OLP
(1) The OLP is attached to the Sealed Compressor used for
the Refrigerator. It prevents the Motor Coil from being
started in the Compressor.
(2) For normal operation of the OLP, do not turn the Adjust
Screw of the OLP in any way.
