4-2-8 Note for using the PTC-Starter / Combo
(1) Be careful not to allow over-voltage and over-current
(2) Do not drop or handle carelessly.
(3) Keep away from any liquid.
If liquid such as oil or water enters the PTC/Combo,
PTC/Combo materials may fail due to breakdown of their
insulating capabilities.
(4) If the exterior of the PTC/Combo is damaged, the resistance
value may be altered. This can cause damage to the
compressor and result in a no-start or hard-to-start condition.
(5) Always use the PTC/Combo designed for the compressor
and make sure it is properly attached to the compressor. Parts
may appear physically identical but could have different
electrical ratings. Replace parts by part number and model
number. Using an incorrect part could result in damage to the
product, fire, injury, or possibly death.

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 activating the bimetal spring in
the OLP.
(2) When high current flows to the compressor motor, the
bimetal wors 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 anyway.
4-2-6 Motor Resarting and PTC/ Combo Cooling
(1) It requires approximately 5 minutes for the pressure to
equalize before the compressor can restart.
(2) The PTC/Combo device generates hea during operation.
Therefore, it must be allowed to cool before the compressor can
restart.
4-2-7 Relation of PTC-Starter / Combo and OLP
(1) If the compressor attempts to restart before the PTC/Combo
device is cooled, the PTC/Combo device will allow current to
flow only to the main winding.
(2) The OLP will open because of the over current condition.
Thissame process will continue (3 to 5 times) when the
compressor attempts to restart until the PTC/Combo device has
cooled. The corret OLP must be properly attached to prevent
damage to the compressor.
Parts may appear physically identical but could have different
electrical ratings. Replace parts by part number and model
number. Using an incorrect part could result in damage to the
product, fire, injury, or possibly death.
