4) Ice production
4-1) After eject waiting time from the water supply, the control board will check the temperature.
4-2) If the sensor reads the temperature lower than -17℃ for more than 5 minutes, than the ice production process is
completed.
5) Test function
In order to operate a test function, press the knob (Test Switch) for 1.5 second.
This function can be used to check a proper working, to clean the ice tray, and to adjust the water level in the ice tray.
5-1) This function only works when the ice tray is leveled and the ice full signal is cleared.
5-2) When the water line is connected, each process such as a water supply, ejection, and leveling, can be investigated
by this button.
●
●
6) Water Dispenser Function
6-1) This function is directly connected to tap water. When the Water Lever is pressed, the water solenoid valve will be
open and water will come out. If the water extracting function is faulty, check out the solenoid, the connection pipe
and the status of water supply and repair it
7) Ice off function
7-1) When the ice select button is pressed for more than 3 seconds, ICE OFF will be selected and when it is pressed for
more than 3 seconds again, ICE OFF will be cancelled.
7-2) Ice production is on with the power on. So, WATER is automatically selected and it lights up.
7-3) When ICE OFF is selected, the ice maker does not operate.
7-4) As ICE OFF is selected, the ICE OFF LED goes on immediately. And, during ice ejection, water supply or
restoration of the horizontal state, it will stop producing ice after the completion of the final water supply.
8) Functions when the freezer door is open
When the freeze door is open, all ice maker related processes will cease in order to minimize noise and to prevent ice
from dispensing.
8-1) The ice tray stops moving.
8-2) The water supply process remains working as usual.
8-3) If the Ice-Tray is tilted over slightly or deviated from its horizontal position when checking the door inside, it
indicates that the F-Door got opened during the ice ejection. If the tray does not return to its horizontal position
more than 30 seconds after the door is closed, it can be considered to be faulty. If the F-Room stops working due
to its door open, its Test function doesn ’t work because it is under actual operation.
8-4) When it goes into the Test function with the Test button pressed, it carries out Ice Ejection regardless of the F-Door Open.
●
9) Ice Eject Function
● After the completion of the ice making, the operation of ice separation from the ice tray will be carried out as follows.
According to the state of the Ice Eject S/W, it is classified as Full Ice Bin and Not Full Ice Bin.
Ice Bin Full : 1st Step → 2nd Step → 3 rd Step → 4th Step → 5th Step → 6th Step
Ice Bin Not Full : 1st Step → 2nd Step → 6th Step
19
Operating Instructions & Installation
9-1) 1st Step : It is an ice temperature checking step for ice ejection. It checks whether the ice temperature is lower than 17.0 ℃ and it has passed 58 mins (58~110 mins : refere to table 3-1) after water supply.
- When F-Defrost goes into operation during the ice eject standby, it will be counted from the start after the
completion of Defrost and it will be checked if it has passed 58 minutes after the completion of F-Defrost.
When the Ice Maker Sensor temperature becomes lower than -17.0 ℃and maintains it for 5 minutes , it will
proceed to the next stage.
9-2) 2nd Step: To separate ice from the ice tray, it will turn over the ice tray by rotating the Eject Motor clockwise.
- Ice Bin Full: When the Ice Eject S/W becomes on again within 3.6 seconds from the point that it is turned
off after the clockwise rotation of the Ice Eject Motor, it indicates Ice Bin Full. So, it will stop the clockwise
rotation and start counterclockwise rotation after one second. The sixth step will be carried out.
- Ice Eject S/W does not become on again within 3.6 seconds, it will be evaluated as Ice Bin Not Full. In this
case, normal ice eject operation will be carried out and it will perform the next 3 rd step.
rd
9-3) 3 Step : When the Ice Eject S/W does not become on again within 3.6 seconds from the point that it is turned off after the
clockwise rotation of the Ice Eject Motor, it is regarded as normal ice eject operation. When the F-Door is opened
during the ice ejecting operation ever since, it will hold the operation and operate again with the door closed.
9-4) 4th Step : When the Ice Eject S/W is turned on after 3.6 seconds, it will stop rotating. And, it will be regarded as the
maximum twist point and it will standby for a second at this maximum twist point.
9-5) 5th Step : It is a step that the ice tray restores to its horizontal position by rotating the Ice Eject Motor counter
clockwise. After the 4 th Step, the Ice Eject Motor will rotate counter clockwise. At this time, the Ice Eject
S/W will check signals called “ Return Pulse” from the Feeler Arm whether there is ice in the ice bin or not.
9-6) 6th Step : When the Ice Eject S/W becomes on after the detection of “ Return Pulse” , it will stop the counter clockwise
rotation of the Ice Eject Motor and consider it to be leveled horizontally. At this time, if it is restored to its
horizontal position after the detection of Ice Bin Full, it will not supply water and try to eject ice every hour
until the Ice Bin Full is cancelled. Also, it will supply water when normal ice ejection is carried out.
9-7) The figure indicates operation specs for normal ice ejection (Ice Bin Not Full / Ice Bin Full.)

3-10) Defrost Function
1) A defrost is determined based on the accumulated compressor on-time.
2) When the power is engaged for the first time, the defrost cycle for the freezer and the refrigerator will begin after 4
hours of the accumulated compressor on-time.
3) A defrost interval depends on the ambient temperature, the number of door openings, and the door open time.
4) A minimum interval is 6 hours and a maximum is 12 hours for the refrigerator, and 12 hours and 24 hours for the
freezer, respectively.

Troubleshooting
6-9) If the lamps of freezer / refrigerator does not light.
Caution!
1. When you are exchanging the lamp of freezer, please exchange or troubleshoot it with the power OFF to
avoid an electric shock.
2. Please keep in mind you do not get burnt by the excessive heating of an incandescent light bulb.
Start
YES
Is the inside lamp filament cut?
How to check :
Separate the door S/W and measure its
resistance with a measure. As the result,
every Open/Close of the door S/W should turn 0/
∞, respectively.
1) Where 0 alone comes out : Door S/W has Short
trouble.
2) Where ∞ alone comes out : Door S/W has
Open trouble.
Exchange or troubleshoot the
inside lamp.
NO
Does the F-door S/W
have a normal contact?
YES
NO
Exchange or troubleshoot the
door S/W
Check the connections of F and R-door S/W;
check and troubleshoot the inside lamp socket.
Reference
If the door is opened, then the contact of door S/W is opened and MICOM gets applied 5V to finally sense Open. If 5V has been sensed over two
minutes afterwards, then an Door-Open alarm will sound ‘Ding-Dong’ for 10 seconds in a one-minute cycle. For that reason, if the door S/W has failure, the
refrigerator can make a “Ding-Dong” sound per a one-minute cycle. Please note step for its service!

Troubleshooting
6-10) When the Dispenser Cover does not close
Note
1) When the Dispenser S/W is pressed after selecting the type of ice (CUBED or CRUSHED), the Geared Motor will operate
and the Dispenser Cover will be opened. When the button keeps on being pressed, ice comes out. If the Geared Motor does
not operate, check the Dispenser S/W first. Also, take out the Geared Motor and check its resistance at the both terminals.
When it is 0 ohm, it is shorted and must be replaced.
Start
It operates with the Freezer door closed.
NO
Does it work when
the Dispenser S/W is pressed?
YES
NO
Does Main MICOM Pin No.
58 on the MAIN PCB change from
5V to 0V when the Dispenser
S/W is pressed?
Does it stop when it is open completely?
NO
① Check Dispenser S/W (Defective
S/W or Wiring)
YES
② Check wiring between MAIN PCB
YES
Does Main MICOM Pin No.
62 change from 0V to 5V?

PCB
② Replace IC74
YES
Does it close in 5 sec after ice come out?
Does the voltage at
the both RY7B coil terminals
change from 12V to 0V?
The entire Cover Ice Route control
system is OK.
① Replace Relay RY7B
YES
YES
and Dispenser
Does the RY7B contact operate normally
(Open/Close)?
① Replace Relay RY7B
** Disconnect CN71 and check it
YES
① Check Ice Transfer Motor
② Check Wiring of Ice Transfer Motor
Does Main MICOM Pin No.
40 & 41 becomes 0V/5V?
YES
* The circuit is OK.
① Check mechanical interferences
54
NO
① Check Dispenser S/W (Defective S/W or
Wiring)
② Check wiring between MAIN PCB and
Dispenser
Troubleshooting
6-11) If Crushed Ice/Cubed Ice doesn’t work properly:
The close condition on operation
is subject to the freezer door.
Start
NO
Is ice ejected?
YES
Does ice in the ice tray exist ?
NO
YES
1) Check the ice-ejector S/W.
2) Check the door S/W.
3) Check the ice moving motor.
4) Check the cut of wire in the Ice
moving Motor section.
Do you see Ice Stop on the digital panel?
YES
1) Check the water hose for folding or
fastening.
2) Check the ice-water-way and
solenoid value
3) Check the wires of ice-maker.
Cancel Ice Stop, select
the Cubed/Crushed ice.
Crushed ice
What’s your selection
between crushed and cubed?
Cubed ice
YES
Is the Crushed Ice extracted
sufficiently?
Is the cube ice ejected sufficiently?
Measure both contact
terminals of RY7B after the
separation of CN71
connectors.
YES
Failure of Main PCB and exchange it.
NO
Does the voltage
of IC74 No. 15 turn 0V even in the ice
S/W OFF?
Failure of Main PCB. –Exchange it.
NO
Does IC74 No. 15 turn 0V if
pressing Dispenser S/W?

Circuit Descriptions
12-1) Source Power Circuit
This circuit shows SMPS(Switch Mode Power Supply) which converts AC input voltage (230V, 50Hz) to a high DC voltage
(340V). The input AC source power is converted to DC through a wave rectifier (BD1) and the converted DC power will
generate a constant waveform on the switching transformer using a high speed (100KHz) switching motion of TOP223Y.
The D104 will rectify the generated voltage and transform into a steady 12V DC source power used for the digital display
panel and relays. The regulator (KA7805) finally transforms into 5V DC source power for the control board and sensor’s
circuits.
Caution) Be careful to handle this circuit due to high voltage (AC230V, DC320V)

→ Door Parts Funtion
1 ) F-Room door open is picked up based on the state (5V/0V)of the MICOM No.31 Port.
When the F-Room door opens, it becomes short between the Door S/W 1&2.And Door S/W 3&4 open.
Vcc → R401 → Door S/W (3&4)open → R402(10K) → MICOM 31 PORT.
When the state of MICOM 31 PORT is 0.7V, the door is picked up as closed. When it is 5V, the door is considered to be open.
2) R-Room door open is picked up based on the state (5V/0V)of the MICOM No.32 Port.
When the R-Room door opens, it becomes short between the Door S/W 1 &2.And Door S/W 3&4 open.
Vcc →R403 → Door S/W (3&4)open → R404(10K) → MICOM 32 PORT.
When the state of MICOM 44 PORT is 0V,the door is picked up as closed. When it is 5V, the door is considered to be open.
3) When door open is detected, the MICOM have the relevant Fan Motor stop and the relevant Room Lamp light up.
Depending on the state of Door Open/Close,there are following operations; Lamp On/Off, Fan Motor On/Off and Door open alarm.
So, check relevant items upon A/S.

Circuit Descriptions
12-5) Temperature Sensing Circuit
1) A thermistor with a negative temperature coefficient (NTC) is used for a
temperature sensor.
2) Resistors, R 303 � R312 and capacitors, C 302 � C 306 are used for
a noise protection purpose.
3) For the F-sensor, the input voltage into the micro processor (MICOM),
VF is calculated by (Rth x Vcc)/(R301+ Rth), where Rth is a
corresponding resistance to the thermistor’s output (below table Table).
This devided
voltage is detected
by MICOM
Temperature

Table of temperature sensor according to resistance and voltage conversion.
- The input voltage to the MICOM PORT could be different by a hardware.
This is a table based on the voltage using the 10kohm-F.
MICOM PORT voltage when the sensor is open: about DC 5V(Vcc LEVEL)
MICOM PORT voltage when the sensor is shorted: about DC 0V(Ground LEVEL)

Circuit Descriptions
12-6) Key Scan and Display Circuit
1) Key Scan and display operation.
The model uses a decorder IC which 4 inputs and 9
outputs. If the IC 9 decorder (TC4028BP) receivesd
signals from MICOM pins (3�6), an output signal per
2 miliseconds comes out from Q3, Q41, Q8, Q6, Q9,
Q7, Q0, Q2, and Q4 pin in sequence. This signal
enters to a driver IC input terminal of the CoolSelect
ZoneTM PCB and IC5 (TD 62783AP), then approximate
11V peaks will generate from an output terminal as
shown on the next page.
79
Circuit Descriptions
The step signals of DC 11~2V will be generated periodically. If a sink signal outputs from IC4, DC 11-12V will be applied
to the LED input terminal and sink the LED output terminal to 0V. Therefore, LED will be ON for 2 miliseconds.
2) Key Scan
The 6 step signals, Q6~Q4 are applied to scan the 6 keys (buttons). When SW6 is pressed, the step signal 5V
from IC50 Q60 will be amplified to 12V and entered to the panel PCB.
This signal will reach to SW6 throogh CN50 pin2, and 12V signal enlered to CN50 lst pin during SW6 being
pressed.
The signal (DC 12V) will be reduced to 5V by R502 and R501, and ented to the MICOM 29 at the same time of
output signal of Q6, then MICOM will match a corresponding function for SN6 is pressed.
2-1) IC50 Q6(5V) → IC51 NO3(5V) → IC51 NO16 (12V) → VN50 NO2(12V) → Panel PCB Connector NO2(12V)
→ SW6 → Panel PCB Connector NO1(12V) → CN50 NO2(12V) → R502/R5.1 → Voltage Down(5V) →
Input MICOM NO29(5V)

Circuit Descriptions
12-7) CoolSelect ZoneTM Panel Circuit
1) CoolSelect ZoneTM display panel and temperature sensor, Lamp PCB
1-1) CoolSelect ZoneTM is referred to as a storage drawer to implement features of Soft Freeze, 0 Zone, Quick cool, Cool
and Thaw
1-2) CoolSelect ZoneTM has an additional display panel.Panel LED are off while the doors are closed.When a door is
opened,micro-processor senses its signal and LEDs will be on.
1-3) The basic operational principle is the same as the Panel pcb key scan process.
1-4) The additional sensor can measure the temperature of CoolSelect ZoneTM.
This sensor enables to control the features of CoolSelect ZoneTM.
2) Damper drive circuit
81
Circuit Descriptions
2-1) CoolSelect ZoneTM Drawer is controlled by a damper to supply or block cold air. For Quick Cool, the damper will be
closed. So cold air is supplied only to CoolSelect ZoneTM Drawer.For Thaw, the evaporator heater of refrigerator is
ON and the damper is controlled by the refrigerator temperature.
2-2) The stepping motor controlled by a Driver IC TA7774P(IC7) operates the damper. The stepping motor uses 4
combined signals to open and close the damper.
Note) To prevent the malfunction from a high humidity, a DC 12V, 1 watt heater is mounted and activated continuously.
12-8) Fan Motor (BLDC) Drive Circuit
1) Motor drive circuit
1-1) This refrigerator adopts a BLDC motor for reduce energy consumption, Motors of the freezer, refrigerator and the
machine compartment are composed of the BLDC. (This circuit is used to other models in common.)
1-2) Operating Principle
In the above circuit, there are similarities between motors in the composition of their circuits. Here comes the F-Fan
motor for example. According to conditions, the F-Fan motor runs High or Low in RPM. To opernte the F-Fan
motor, a specific voltage should be applied to OP-AMP No.2 as shown in the figure. When MICOM No.50 is 0V,
OP-AMP No.2 also becomes 0V. So, the motor does not operate. When MICOM No.50 becomes High (5V), the
forward voltage drop of R701 and D701 (IN4148) will be subtracted from the High voltage and then voltage will
decided through the division with R707 10K. The devided voltage then flows to OP-AMP No.2 amplifying treble
voltage. It applies to the motor. If the voltage at OP-AMP No.2 is 3V, 3V x 3 = 9V applies to the motor. (When the FFan is High, 5V will be output from MICOM No.2 and when it is running in Low RPM, MICOM No.2 becomes 0V
and 5V will be output from MICOM No.49. So, when the F-Fan is turned off, both of MICOM 50 & 49 becomes 0V.)
** Other fan motors run with the same principle.

In the normal operation, MICOM No. 33, 34, 35 and 42 receive a constant frequency; and
MICOM defects the signal to check the failure of motor.
(frequency(Hz)×12 = motor rpm)
Note) According to conditions, the F-Fan and the C-Fan motors are controlled to High and Low RPM. Generally, the
refrigerator operates in High RPM during the peak using time and it runs in Low RPM when the use of the
refrigerator is slow. (For the purpose of performance improvements, the motor RPM, Voltage and Frequency can
be changed without a notice in advance.)
82
Circuit Descriptions
1-4) When there is error in the motor (if the motor is sensed under 600 ~ 700 RPM), the relevant motor stops
immediately and it tries to start up in 10 seconds. At this time, when the RPM is sensed as normal, the motor will
be judged as normal and it starts operating. But, when a normal RPM is not input, it tries to start up again in 10
seconds. If it refuses to start up for 5 times, it will pause for 10 minutes, and repeat a 5-times trial with an interval of
10 seconds continually. At this time, when the Self-Diagnosis function is selected on the display panel, the LED
relevant to the operation error will light up indicating that there is a problem with the motor. When the power is off,
the error data will be erased. So, do not turn off the power before it is checked by service personel.
Note) When the fan motor error is expected during a service check, do not turn off the power but to carry out the SelfDiagnosis function and check the current status of the refrigerator.
12-9) EEPROM Circuit
EEPROM is semiconductor memory not to be
erased. It can be used in the area of unstable
electric power.
12-10) Option Circuit
There are a variety of models that have a
different function. A different model can set up to
use option circuit as shown.
83
Circuit Descriptions
12-11) Load Drive Circuit
1) The control of load in the system is accomplished by the main PCB.
2) Most of relays or SSRs can control the compressor, refrigerator/freezer defrost heater, and several option
functions.
3) For the compressor, #37 pin of micro processor signals High (5V). This signal enters #8 pin of IC73 and #11 of
output terminal which have base and collector functions of IC73 turns on and connects the GND. Relay 72 will
be grounded through #11 of IC73.Magnetic field will generate so that the second side of RY72 is activated and
230V is supplied to the compressor. On the other hands, if #37 of micro processor turns Low(0V), #8 of IC73,
the current of RY 72 relay, and magnetic field will shut down in sequence. A contact point in secondary side of
Relay 72 is off. Finally compressor will stop.
4) The principles of other loads is the same as 3) item described.
Note) SSR(Solid State Relay) is a kind of Relay.
