4-2-3 PTC-Applied Circuit Diagram
•Starting Method for the Motor
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.
OVERLOAD PROTECTOR
N
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.

PTC STARTER
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 BaTiO3.
(2) The higher the temperature is, the higher the resistance
value. These features are used as a starting device for
the Motor.

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
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.
4-2-2 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.
-8-
4-4 TO REMOVE THE COVER PTC
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.
1) Remove the Cover Back M/C.
(2) Disconnect two housing upper side of comp connected
in.

8. DESCRIPTION OF FUNCTION & CIRCUIT OF MICOM
8-1 FUNCTION
8-1-1 Function
1. When the appliance is plugged in, it is set to "4" for Refrigerator and "4" for freezer.
You can adjust the Refrigerator and the Freezer control temperature by pressing the ADJUST button.
2. When the power is initially applied or restored after a power failure, it is automatically set to "4" & "4".
8-1-2 Control of freezer fan motor
1. Freezer fan motor has high and standard RPMs.
2. High RPM is used when electricity is first on, for ICE PLUS , and when refrigerator is overloaded.
But standard RPM is used for general purposes.
3. To improve cooling speed and load corresponding speed, the RPM of freezer fan motor shall change from normal speed
to hign speed.
4. High speed (2500RPM) : Initial power on or load corresponding operation, ICE PLUS.
Normal speed ( 2200 RPM): general working conditions.
5. Fan motor is stopped when Refrigerator Door is Opened.
6. The fan motor is stopped when Freezer Door is Opened (only if compressor status is OFF)
8-1-3 ICE PLUS
1. The purpose of this function is to intensify the cooling speed of freezer and to increase the amount of ice.
2. Whenever selection switch is pressed, selection/release, the LED will turn ON or OFF.
3. If there is a power cut and the refrigerator is power on again, ICE PLUS function will be canceled.
4.To activate these function you need to press the ICE PLUS key and the LED will turn ON. This function will remain
activated for 24 hrs. The first three hours the compressor and ICE PLUS will be ON. The next 21hours the freezer will
be controlled at the lowest temperature. After 24 hours or if the ICE PLUS key is pressed again, the freezer will
return to its previous temperature.
5. For the first three hours notice the following cases:
(1) Compressor and freezer fan(HIGH RPM) continuously operate for three hours.
(2) If defrost starts during ICE PLUS, ICE PLUS operates for the rest of time after defrost is
completed, when ICE PLUS operation time is less than 90 minutes.
If ICE PLUS operates for more than 90minutes, the ICE PLUS will operate for two hours after
defrost is completed.
(3) If ICE PLUS is pressed during defrost, ICE PLUS LED is on but this function will start seven
minutes after defrost is completed and it shall operate for three hours.
(4) If ICE PLUS is selected within seven minutes after compressor has stopped, the compressor (compressor
delays seven minutes) shall start after the balance of the delay time.
(5) The fan motor in the freezer compartment rotates at high speed during ICE PLUS.
6. For the rest of 21 hours, the freezer will be controlled at the lowest temperature.
8-1-4. REFRIGERATOR LAMP AUTO OFF
1. To protect the risk of lamp heat, when Refrigerator door opens for 7 min., refrigerator lamp is auto off.
- 20-
8-1-5 Alarm for Open Door
1. This feature sounds a buzzer when the freezer or refrigerator door is not closed within 1 minute after it is opened.
2. One minute after the door is opened, the buzzer sounds three times each for 1/2 seconds. These tones repeat every 30
seconds.
3. The alarm is cancelled when the freezer or the refrigerator is closed while the buzzer sounds.

When the button on the front Display is pushed, a Ding~ Dong~ sound is produced.
(Refer to the Buzzer Circuit 8-2-4 No. 3)
8-1-7 Defrosting (removing frost)
1. Defrosting starts each time when compressor running time reach 7 hours, if any door hasn´t been opened
2. In case of any Door has been opened the defrosting period will start considering the next conditions:
If Compressor running time is bigger than 7 hrs when door is opened: Defrosting starts immediately.
If compressor running time is less than 7 hours when door is opened: Defrosting starts after a compensation time is applied
3. For initial power on or for restoring power, defrosting starts when the compressor running time reaches 4 hours.
4. Defrosting stops if the sensor temperature reaches 46.4°F(8° C) or more. If the sensor doesn’t reach 46.4°F(8° C) in
2 hours, the defrost mode is malfunctioning. (Circuit 8.1.9)
5. Defrosting won’t function if its sensor is defective (wires are cut or short circuited)
8-1-8 Electrical Parts Are Turned On Sequentially
Electrical parts such as COMP, defrosting heater, freezer FAN, etc. are turned on in the following order to prevent noise and
parts damage. Several parts are started at the same time at initial power on and are turned off together when TEST is
completed.
