4-3-1 Definition
of OLP
(1) OLP (OVERLOAD
PROTECTOR)
is attached to the
Compressor and protects the Motor by cutting the
current to the Motor if the temperature rises and
activates the bimetal spring in the OLP.
(2) When over-voltage flows to Compressor motor, the
Bimetal works by heating the heater inside the OLP,
and the OLP protects Motor by cutting off current which
flows to the Compressor Motor.

(1) The OLP is attached to the Hermetic Compressor used
for the Refrigerator and Show Case and prevents the
Motor Coil from being started in the Compressor.
(2) Do not turn the Adjust Screw of the OLP in any way for
normal operation of the OLP.
