1) Remove freezer drawers.
2) Remove two cap, screws and loosen two screws in Grille Fan.
3) Pull out the Grille Fan and Shroud, F.
4) Disconnect the housing of lead wire.
5) Separate the Fan Assy.
6) Losse 2 screw fixed to the Bracket.
7) Pull out Shroud, F remove the Fan Motor Assy.
8) Separate the Motor Bracket and Rubber.

Defrost Control Assy consists of Thermistor and Fuse, Melting.
Thermistor functions to defrost automatically and it is attached to
metal side of the Evaporator and senses temperature.
Fuse, Melting is a kind of safety device for preventing overheating
of the Heater when defrosting. 
At the temperature of 72¡C, it stops the emission of heat from the
Heater.
1) Pull out the Shroud, F after removing the Grille.
2) Separate the connector connected with the Defrost Control

Assy and replace new one.

1) Remove the Cover Lamp, R and loosen 2 screw.
2) Pull the Control Box, R and separate the lead wire

housing.

3) Remove the Cover Lamp, R.
4) Separate the Insulation Multi Duct and Control Box, R.
5) Disassemble the Knob.
6) Separate the Damper Control and Control Box, R.
7) Separate the Damper Control and Resistor.
8) Disconnect the lead wire.

In this refrigerator, Heater, Sheath is used for defrosting
heater. During heating, the temperature of heater rises
about 300~500¡C. Therefore, be careful not to burn while
servicing.
1) After removing the Grille and Shroud, separate the

Heater, Sheath by disconnecting the connectors.

2) Exchanged Heater, Sheath and connected the housing.

The compressor intakes low temperature and low pressure
gas evaporated from Evaporator of the Refrigerator, and
condenses this gas to high temperature and high pressure
gas, and then plays delivering role to Condenser.

2) Composition
The Compressor is Composed of Compressor Apparatus
compressing gas, Compressor Motor moving Compressor
Apparatus and Case protecting Compressor Apparatus
and Motor. There are PTC-Starter, and Over Load
Protector (OLP) in the Compressor outside. On the other
hand, because the Compressor consists of 1/1000mm processing
precision components and is sealed after production in absence
of dust or humidity, deal and repair with care.

3) Note for Usage
(1) Be careful not to allow over-voltage and over-current.
(2) No Strike 

If applying forcible power or strike (dropping or careless
dealing), poor operation and noise may occur.

(3) Use proper electric components appropriate to the

Compressor.

(4) Note to Keep Compressor.

If Compressor gets wet in the rain and rust in the pin of
Hermetic Terminal, the result may be poor operation
and poor contact may cause.

(5) Be careful that dust, humidity, and flux welding don't

inflow in the Compressor inside in replacing the
Compressor. Dust, humidity, and flux due to welding
which inflows to Cylinder may cause lockage and noise.

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

semiconductor starting device which uses ceramic
material and this material consists of BaTiO

3

.

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

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

2) Role of PTC-Starter
(1) PTC is attached to Hermetic Compressor used for

Refrigerator, Show Case and starts Motor.

(2) Compressor for household refrigerator applies to

single-phase induction Motor.
For normal operation of the single-phase induction
motor, in the starting operation flows in both main coil
and sub-coil. After the starting is over, the current in
subcoil is cut off. The proper features of PTC play all
the above roles. So, PTC is used as a motor starting
device.

● 

4) Motor Restarting and PTC Cooling
(1) For restarting after power off during normal

Compressor Motor operation, plug the power cord after
5 min. for pressure balance of Refrigerating Cycle and
PTC cooling.

(2) During normal operation of the Compressor Motor, PTC

elements generate heat continuously. Therefore, 
if PTC isn't cooled for a while after the power has been
shut off, Motor can't operate again.

5) Relation of PTC-Starter and OLP
(1) If the power is off during operation of Compressor and

the power is on before the PTC is cooled, (instant shut-
off within 2 min. or reconnect a power plug due to
misconnecting), the PTC isn't cooled and a resistance
value grows. As a result, current can't flow to the sub-
coil and the Motor can't operate and the OLP operates
by flowing over current in only in the main-coil.

(2) While the OLP repeats on and off operation about 3-5

times, PTC is cooled and Compressor Motor performs
normal operation.
If OLP doesn't operate when PTC is not cooled,
Compressor Motor is worn away and causes circuit-
short and fire. Therefore, use a properly fixed OLP
without fail.

6) Note to Use PTC-Starter
(1) Be careful not to allow over-voltage and over-current.
(2) No Strike

Don't apply a forcible power or strike.

(3) Keep apart from any liquid.

If liquid such as oil or water away enter the PTC, 
PTC materials it may break due to insulation
breakdown of the material itself.

(4) Don't change PTC at your convenience.

Don't disassemble PTC and mold. If the exterior to the
PTC-starter is damaged, resistance value is altered and
it may cause poor starting of the compressor motor
may cause.

(5) Use a properly fixed PTC.

1) Definition of OLP
(1) OLP (OVER LOAD PROTECTOR) is attached to the

Hermetic Compressor and protects the Motor by cutting
off current in Compressor Motor in case of over-rising
temperature by Bimetal 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.

2) Role of the OLP
(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.
