OVERLOAD PROTECTOR

4-1 COMPRESSOR

4-1-1 Role

The compressor intakes low temperature and low pressure
gas from the evaporator of the refrigerator and compresses
this gas to high-temperature and high-pressure gas. It then
delivers the gas to the condenser.

4-1-2 Composition

The compressor includes overload protection. The PTC
starter and OLP (overload protector) are attached to the
outside of the compressor. Since the compressor is
manufactured to tolerances of 1 micron and is hermetically
sealed in a dust and moisture-free environment, use
extreme caution when repairing it.

4-1-3 Note for Usage

(1) Be careful not to allow over-voltage and over-current.
(2) If compressor is dropped or handled carelessly, poor

operation and noise may result.

(3) Use proper electric components appropriate to the

Particular Compressor in your product.

(4) Keep Compressor dry.

If the Compressor gets wet (in the rain or a damp
environment) and rust forms in the pin of the Hermetic
Terminal, poor operation and contact may result.

(5) When replacing the Compressor, be careful that dust,

humidity, and soldering flux don’t contaminate the inside
of the compressor. Contamination in the cylinder may
cause noise, improper operation or even cause it to
lock up.

4-2 PTC-STARTER

4-2-1 Composition of PTC-Starter

(1) PTC (Positive Temperature Coefficient) is a no-contact

semiconductor starting device which uses ceramic
material consisting of BaTiO

(2) The higher the temperature is, the higher the resistance

value. These features are used as a starting device for
the Motor.

4-2-2 Role of PTC-Starter

(1) The PTC is attached to the Sealed Compressor and is

used for starting the Motor.

(2) The compressor is a single-phase induction motor.

Durign the starting operation, the PTC allows current
flow to both the start winding and main winding.

4-2-3 PTC-Applied Circuit Diagram

● Starting Method for the Motor

Figure 18

4-2-4 Motor Restarting and PTC Cooling

(1) It requires approximately 5 minutes for the pressure to

equalize before the compressor can restart.

(2) The PTC device generates heat during operation.

Therefore, it must be allowed to cool before the
compressor can restart.

4-2-5 Relation of PTC-Starter and OLP

(1) If the compressor attempts to restart before the PTC

device is cooled, the PTC device will allow current to
flow only to the main winding.

(2) The OLP will open because of the over current

condition. This same process will continue (3 to 5
times) when the compressor attempts to restart until
the PTC device has cooled. The correct 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

3.

number and model number. Using an incorrect part
could result in damage to the product, fire, injury, or
possibly death.

4-2-6 Note for Using the PTC-Starter

(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,
PTC materials may fail due to breakdown of their
insulating capabilities.

(4) If the exterior of the PTC 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 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.

4-3-1 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.

4-4 TO REMOVE THE COVER PTC

(1) Remove the Cover Back M/C.

(2) Disconnect two housing upper side of comp connected

in.

(3) Loosen two screws on comp base.

7-2-1 Start Position

1. After POWER OFF or Power Outage, check the EJECTOR's position with MICOM initialization to restart.

2. How to check if it is in place:

- Check HIGH/LOW signals from HALL SENSOR in MICOM PIN.

3. Control Method to check if it is in place:
(1) EJECTOR is in place,

- It is an initialized control, so the mode can be changed to ice making control.

(2) EJECTOR isn't in place:

A. If EJECTOR is back in place within 2 minutes with the motor on, it is being initialized. If not, go to Step B.
B. If EJECTOR is back in place within 18 minutes after the heater turns from ON to OFF, it is being initialized. If not, it is

not functioning. Repeat Step B with Heater and Motor off.

7-2-2 Ice Making Mode

1. Ice Making refers to the freezing of supplied water in the ice trays. Complete freezing is assured by measuring the
temperature of the Tray with Ice-Making SENSOR.

2. Ice Making starts after completion of the water fill operation.

3. The Ice Making function is completed when the sensor reaches 19°F(-7°C), 60 to 240 minutes after starting.

4. If the temperature sensor is defective, the ice-making function will be completed in 4 hours.

NOTE : After Icemaker Power is ON, the Icemaker heater will be on for test for 9 sec.

7-2-3 Harvest Mode

1. Harvest (Ice removing) refers to the operation of dropping cubes into the ice bin from the tray when ice-making has
completed.

2. Harvest mode:
(1) The Heater is ON for 30 seconds, then the motor starts.
(2) After performing Step 1 (the Heater is turned OFF), the Ejector will be back in place wthin 18 minutes. (Hall SENSOR

sign = OV). Ice removal is then complete. Then the Ice Maker cycles to the Fill Mode. The water supply fails to start, it
is not functioning. Put the Heater and Motor in the off position. Restart every 2 hours. (Refer to fig.1)

NOTE : If the motor malfunctions and starts before the detect lever rises, MICOM regards the Ice-Removing phase as
completed. Water then starts flowing. To prevent this, MICOM doesn’t switch to water-supply mode, but restarts the ice­removing mode. If this happens 3 times, the motor is malfunctioning and you should stop the loads (Heater, Motor). Then
restart the Ice-Removing mode every 2 hours. (See Step 2 above.)

7-2-5 Function TEST

1. This is a compulsory operation for TEST, SVC, cleaning, etc. It is operated by pressing and holding the Fill Key for 3 seconds.

2. The test works only in the Ice Making Mode. It cannot be entered from the Harvest or Fill mode. (If there is an ERROR, it
can only be checked in the TEST mode.)

3. Caution! If the test is performed before water in the Maker is frozen, the Ejector will pass through the water. When the Fill
mode begins (Stage 4), unless the water supply has been shut off, added water will overflow into the ice bin. If the control
doesn’t operate normally in the TEST mode, check and repair as needed.

4. After water is supplied, the normal CYCLE is followed: ice making → Harvest → Fill → Park Position.

5. Five seconds after Stage 5 is completed, the Ice Maker returns to MICOM control. The time needed to supply water
resets to the pre- test setting.

8-2 PCB FUNCTION

8-2-1 Power Circuit

The secondary part of the TRANSFORMER is composed of the power supply for the display, the BLDC FAN Motor drive
(15.5 V), the relay drive (12 Vdc) and the MICOM and IC (5 Vdc).

The voltage for each part is as follows:

VA1 is a part for preventing over voltage and noise. When 385V or higher power is applied, the inside elements are short­circuited and broken, resulting in blowout of the fuse in order to protect the elements of the secondary part of the
TRANSFORMER.

8-2-2 Oscillation Circuit

This circuit generates the base clock for calculating time and the synchro clock for transmitting data from and to the inside
logic elements of the IC1 (MICOM). Be sure to use specified replacement parts, since calculating time by the IC1 may be
changed. If changed, the OSC1 SPEC will not work.

8-2-3 Reset Circuit

The RESET circuit allows all the functions to start at the initial conditions by initializing various parts, including the RAM
inside the MICOM (IC1) when the power is initially supplied or the power supply to the MICOM is restored after a
momentary power failure. For the initial 10ms of power supply, LOW voltage is applied to the MICOM RESET terminal.
During a normal operation, 5V is applied to the RESET terminal. (If a malfunction occurs in the RESET IC, the MICOM will
not operate.)
