unload state. When actually used, temperature may differ according to
surrounding condition and use frequency. The table displays general
characteristic of temperature.

❋ Reference

If Quick Freeze function is selected when freezer temperature is over -10˚C
and Refrigerator temperature is over +10˚C like the condition of initial
Power ON, Refrigerator Fan becomes OFF until freezer temperature
drops under certain temperature. When freezer temperature becomes
under certain temperature, Refrigerator Fan operates.

7-4) Alarm Function

① Button Touch Sound (“Ding-Dong” Sound)

1) Input confirmation sound of “Ding-Dong” sounds when each button of
Control Panel is pressed.

2) “Ding-Dong” doesn’t sound if more than two keys are pressed at the
same time or buttons are wrongly operated.

➁ Door-Open Alarm Sound (“Ding-Dong” Sound)

1) If door of freezer or Refrigerator remains open over 2 minutes, alarm
sounds ten times.

2) If door remains open continually afterward, alarm repeats ten times per one minute
cycle.

3) Alarm stops immediately when door of freezer or Refrigerator is closed.

➂ Forced Operation & Forced Defrost Alarm Sound (“Beep” Sound)

1) If forced operation or forced defrost is selected, “Beep” sound occurs.

2) If forced operation is selected, alarm sound occurs until automatic
cancellation (after 24 hour’s forced operation) or cancellation function is
selected.

3) Also in case of forced defrost, alarm sound occurs until defrost is
completed (including pause) or cancellation function is selected.

7-5) Defrost Function

① At time of initial Power On, defrost function works for both freezer and Refrigerator at

the same time, when integrating time of Comp On is over 4 hours.

➁ Afterward defrost cycle is changeable according to use condition or surrounding

environment from 6 hrs. to 38 hrs..

➂ After completing the initial defrost, PRE-COOL function works for 20 min. to minimize

temperature increase by defrost work. However, PRE-COOL function is determined
according to temperature in Refrigerator at the point of defrost time.

➃ If F-room temperature is over -21˚C, PRE-COOL function works for F-room. If F room

temperature is below -21˚C, PRE-COOL function does not work.

7-6) Test Function

● Test function is for test, process inspection and SVC of PCB and product.

● After selecting test S/W and confirming function of product, turn on power switch

again to operate self-inspection function.

● If you press Quick Freezer Key on Display Panel and temperature control Key in
R-room for more than 8 seconds, all Displays will be turned off and continue

operating in Test Mode. At this moment, if any key is pressed among freezer
temperature control key, Refrigerator temperature control key, quick freeze key or
vacation key, it operates as the test button.

❈ F-room : Freezer, R room : Refrigerator

① Forced Operating Function

1) In the state where display panel was converted into test mode, if test button
is selected once, COMP will operate immediately without 5 minute
delay function. Therefore, forced operation is conducted at the very moment
of COMP OFF, over load may be caused. Please be careful.

2) If forced operation is selected, freezer and Refrigerator is set to automatic,
and the temperature of freezer is set to “-26˚C”and Refrigerator is set to

“1˚C”, Comp and F-fan operates continuously, and R-fan in Refrigerator is

controlled by “1˚C”setup.

3) Forced operation is valid for 24hrs. That is, if 24hours. pass after
selecting forced operation, simultaneous defrost in both Refrigerator and
freezer is automatically carried out. And normal operation is carried out
by present setup of Refrigerator and freezer.

4) Cancellation of forced operation in the middle of working is possible by
turning on Power after turning it off (resetting), or by selecting test cancel
mode shown in the item 3 below.

5) When forced operation works, alarm sound will continue until forced
operation is completed. There is no alarm cancel function.

➁ Forced Defrost Function

1) In the state of forced operation, if display panel is converted into test mode and
press the test button once more, forced operation is cancelled immediately,
and evaporator defrost function of Refrigerator operates.

2) At this time, beep alarm sounds for 3sec. at the point of defrost, and

0.75sec. ON/0.25sec. off sound occurs during forced defrost function
of Refrigerator works.

3) If above defrost function of Refrigerator is maintained, it operates normally
after defrost is completed.

4) While forced defrost function of Refrigerator operates, pressing the test
button once more enables simultaneous defrost for both freezer and

➁ Self-Diagnosis Function in Normal Operation

1) Under normal operation of Refrigerator, if you press “Quick freeze”and
“Vacation”button at the same time for 6sec., temperature setup display

will proceed On/Off blink of all for 2sec. at 0.5sec. interval.
If you press “Quick freeze”and “Vacation”button continuously at the
same time for about 8sec. including 2sec. of repetition of LED’s On/Off,

self-Diagnosis function is selected.

2) At this moment, it goes into self-Diagnosis function with“Ding-dong”

buzzer sound.

3) When Error occurs, it is restored to normal state regardless of defect

repairing after signal lasts for 30sec. (“Ding-dong”buzzer sound).

4) While it is operating self-Diagnosis function, it does not accept input of

button.

7-8) Load Condition Indicating Function

① In normal operation, if you press “Quick freeze”and “Vacation”button

at the same time for 6 sec., all setup display of freezer and Refrigerator
are turned on. If you hand off from the button at this moment, temperature
setup display of freezer and Refrigerator will proceed On/Off blink of all for
2sec. at 0.5sec. interval. While On/Off blink is processing, if you press the
temperature setup button, it goes into load condition indicating function
(with ding-dong buzzer sound).

➁ Load condition indicating mode shows from which load Micom signal

outputs at present. However, it only shows that micom signal is outputted
and does not confirm whether load is actually operating or not. That is,
even if load is displayed as it is operating, load may not operate because
of actual defect of load or defect of relay on PCB. During A/S, you can
use this function by applying the main function.

➂ Time required to indicate is 30 sec.. After 30sec., it is automatically

restored to the setup state before its function.

➃ Corresponding display indication about load condition is shown as in the

following table.

● This function only applies to a model equipped with ice-maker.

● This function is limited to a model from which ice and water can be taken out

from outside without opening door.

① Cube Ice / Crushed Ice/ Stop (Off) Function

1) At the time of intial power on, when inside temperature of freezer is more than 5℃,
Cube Ice LED light on display is lit on, and Crushed Ice LED light keeps light-off
state. But when power is turned on, if inside temperature of freezer is less than 5℃,
Micom recalls form of ice which was set up before power off so that it displays the
memorized ice form.

2) “Cube”→“ Crushed”→“ Ice Off”is selected in turn by ice selecting Key.

3) In case of selecting “Crushed”mode, it operates Gear Motor to eject crushed ice
to outside when ice lever operates as ice is made in the bowl of ice machine.

4) In case of selecting “Cube”mode, Gear Motor and ice solenoid operate to eject
cube ice to the outside when ice lever operates as ice is made in the vessel of
ice machine.

5) If “Ice Off”is selected, it stops only ice-making function of ice-maker so
that ice is not made.

◆ At the moment of selecting “Ice Off”, ice-making function stops. But, if it is in
the process of ice-isolating, returning to horizontal state and supplying
water, it maintains stoppage state after water supply is completed.

◆ Even when “Ice-Off”function is operating, ice eject lever operates normally.
This is not a defect. Therefore, remained ice in the ice container can be used
normally.

② Ice Timer Function

1) If you press ice timer button, it is automatically set to Ice-Off mode regardless of
present setup condition of ice mode (Cube / Crushed / Ice Off), and ice lamp is
turned on. And time is set to 3 days on temperature control display of freezer at first.
And each time you press the ice button, the number increases one by one. And if it
reaches 30 days, it resumes from 3 days.

2) Among ice timer functions, if you press ice selecting key, ice timer function
is cancelled.

3) If reservation is made by ice timer button, setup temperature of freezer returns to
temperature display of freezer after 5sec.. At this moment, if ice timer button is
pressed again, it displays the previous reserved date again.1-2 days before the
reserved date is completed, ice maker starts operating. And when the reserved date
is completed, more than half of ice bucket is filled.

4) If ice timer is reserved and vacation function operates, vacation function
ends at the same time when ice timer function ends.

7-9) Function of Ice/Water Dispenser when they are equipped.

25

5) The following are examples for use.

◆In case of selecting vacation function only
If you press “vacation”button, Refrigerator will not operate and freezer will operate
only. In case you select this function, take out all foods in the Refrigerator. And “Ice
Off”is automatically selected among ice modes, so ice bucket should be empty and
water supply valve should be turned off.

◆In case of selecting ice timer function only
In case you press “Ice Timer”button to select date as explained above, and not
selecting “Vacation”function so that Refrigerator continues to operate, ice mode is
selected as “Ice Off”and ice is stored in the bucket when you return. Therefore, do
not lock the water supply valve.

◆In case of selecting both vacation and ice timer function
In case you press “Ice Timer”button and “Ice Timer”button to select date to select
date as explained above, or if you press “Ice Timer”button to select date and press

“Vacation”button afterward, Refrigerator does not operate but freezer operates only,

and ice mode is automatically selected as “Ice Off”. So you must take out all foods in
Refrigerator, empty ice in the ice bucket, check water leakage on valves, other hoses
and connection parts without locking water supply valve. When “Vacation”function is
cancelled, Refrigerator resumes its operation.

③ Ice Dispenser Function (Cover Ice Route Solenoid Valve)

1) After 8sec. from initial power on, solenoid of ice exit operates once. This is the
function to prevent interruption of electric service when ice exit is open. So this is not
a defect.

2) With turning the dispenser S/W from on to off and ice ejecting is
completed, 5sec. after turning off S/W, ice exit is closed because cover ice
route solenoid of ice dispenser operates.

④ Water Dispenser Function

1) This function is a system of direct connection with water supply. When water lever is
pressed, water solenoid valve which is equipped at the right side of machine room
opens so as to operate to eject water. However, it has no function to control on
Micom PCB. Therefore, if there happens any defect at water eject function, check
and repair solenoid itself, wire connecting connector, connecting tube and state of
water supply.

⑤ Water Filter Indicator Function

1) After the initial power on, indication lamp is displayed in green light. After 5 months
passed, it is displayed in orange light, and 1 month after this, it is displayed in red
light. This is memorized by EEPROM in Micom PCB, so it counts the passed time
continually though the power is turned on again after it was turned off.

2) If you press ice selecting button and ice-making stop button at the same time for
25sec. continuously, indication lamp lights in green color. And it becomes orange
after 5 months from this moment. And it displays red after 1 month from the
moment.

3) If you press ice selecting button and ice-making stop button at the same time for 5
sec., indication lamp is turned off and water filter indicator function stops. At this
moment, passed time is not counted.

4) At the state where the function is stopped, if you press ice selecting button and ice­making stop button at the same time for 25sec. continuously, “Green”light is turned
on and water filter indicator function will resume. And it becomes orange light after 5
months from this moment. And it displays red light after 1 month from the moment.

26

27

1) In case power is applied to prevent customer from nonsense call about
initialization of freezer and Refrigerator at -20℃ and 3℃ respectively when

a momentary power stoppage (not a long-term power stoppage) occurs
while Refrigerator is operating, it operates in two ways. The first one is
initialization by judging the temperature of inside of freezer, and the second
one is restoration of operation state.

2) At the initial power on, in case temperature of the inside of freezer is
judged as about less than +5℃, it is regarded as momentary power

stoppage during operation. Therefore, functions related with panel display
such as Quick Freeze, Vacation, Freezer setup, Refrigerator setup, Ice
timer, Form of ice, etc. are restored.

3) At the initial power on, in case temperature of the inside of freezer is about
more than +5℃, it is regarded as long-term power stoppage. In this case,
panel display is initialized (Quick off, Vacation off, Freezer is set to -20℃,
Refrigerator is set to 3℃, Ice timer off, Cube selecting).

4) Ice timer function and water filter indication function are not initialized in
case of power stoppage. But during power stoppage, time count does not
progress because Micom in PCB does not operate because power source is
not supplied.

Terminal Oscillation Frequency

Xin(#30)

Xout(#31)

4MHz

4MHz

8-1) Power Source Part

When power is supplied, electric wave is rectified through BD1 to generate voltage of
about DC 300V.Top S/W is automatically switched to the optimum condition according to
load condition of the second part.
When electricity flows between D and S of the top S/W, electricity is generated inside
the trans, and when the power between D and S is turned off, electricity which is
deserted at trans is transmitted to the second part.
This process is repeated to maintain the fixed voltage of 12V by C102 of the second
part. This power supplies electricity to power source of 5V, relay and display, and it
allows operation of main PCB possible.

8-2) Oscillation Circuit Part

It is oscillation circuit for synchronism clock generation and time calculation on
information sending/receiving of internal elements. It does not carry out its normal
function because timing system of MICOM alters in case the specification of resonator
changes.

8-3) Reset Circuit Part

Reset circuit is a circuit which allows the whole program operate on an initial
position by initializing several parts such as RAM inside of MICOM when power is
applied to MICOM. When power is supplied, the reset terminal voltage becomes
several tens ㎲“LOW”state compared with Vcc voltage (DC 5V) of MICOM, and it
maintains “HIGH”(Vcc voltage) state in normal operation condition.

8-4) Door S/W Sensing Circuit

For door open sensing of F room, ② of CN30 is connected to the ground. For ①, Vcc(DC
5V) is supplied through resistance R404(4.7㏀), and “LOW”(0V)/”HIGH(5V) is applied to
MICOM by open/close of the F room door so that it can sense open/close of the F room
door. For door open sensing of R room, ⑥ of CN30 is connected to the ground. For ⑤,
Vcc(DC 5V) is supplied through resistance R403(4.7㏀), and “LOW”(0V)/”HIGH(5V) is
applied to MICOM by open/close of the R room door so that it can sense open/close of
the R room door. At this time, if there is any defect at the door S/W, the corresponding
fan inside the Refrigerator does not work or alarming function works. Therefore, the door
S/W must be checked in case of A/S. That is, if door opens, the corresponding fan inside
the Refrigerator stops without fail. When connection point of S/W has defect, MICOM
judges that door is open so that it stops the fan though the door is closed.

Sensor uses thermistor which has temperature coefficient of negative resistance. When
temperature rises, resistance value gets smaller, and when temperature falls, resistance
value gets larger. R306~R310, C301~C305 are parts for noise prevention, which are not
related to temperature sensing characteristic. In case of F-SENSOR, if setup voltage
inputted to MICOM Referred to as Vf, Vf= (Rth*Vcc)/(R303+Rth). Here, Rth is
resistance value of thermistor corresponding to temperature. See conversion table of

“Refer 6”of this manual on resistance and voltage of sensor about temperature for

Reference. As terminal voltage of MICOM corresponding to temperature is also
designated, Refer to it at A/S time.

8-6) Key Scan & Display Circuit Part

① Key Scan and Display Operation

As is seen on each wave form of the following, send “HIGH”output in an
order of MICOM PIN NO #3→#4→#5→#6→#7→#8 for 2msec in a cycle
of 12msec using six terminals of MICOM NO #3, 4, 5, 6, 7, 8. This signal
appears onto output terminal through input terminal of IC05(UDN2981 or
KID65783AP). At this time, peak-to-peak voltage of the spherical wave is
about 11V(DC RMS1.5), and form of output wave form is like the drawing 1.

② Key Scan

When the wave form of GRID#2 is outputted, this signal is provided to SW6 button
through the resistance of 10㏀. When SW6 is pressed at this time, signal gets smaller
by R501(12㏀), and about 4.5V of peak-to-peak voltage is applied to MICOM.

MICOM judges that the wave form of GRID#1 is inputted, and changes function
corresponding to SW6 KEY. In this way, each wave form of GRID is recognized.

30

8-7) Load Operation Circuit Part

When “HIGH”signal is applied to INPUT terminal of IC03(KID65003AP) from MICOM
PIN NO #16(P07), IC is turned on. At this time, V12(DC12V) which is applied to the one
terminal of coil of COMP relay flows to ground through output of IC03. Then core
generates magnetic field to turn on the connection point, and it applies voltage of 230V
to COMP load to turn on COMP. When MICOM PIN NO #16 changes to “LOW”state,
electricity cannot flow to COMP relay coil because IC is turned off. So relay connection
point becomes to OFF state and stops COMP.
① COMP & F,R Defrost Heater Inter-operation Explanation

Like the above block diagram, operation of F, R defrost heater is determined according
to the operation of relay for COMP. When COMP relay is connected to NO terminal,
COMP operates. However, in case of F, R defrost heater, electricity does not pass
through the heater though relay works. But, if COMP relay is connected to MC terminal,
COMP does not operate and heater gets electricity according to operation of F, R
defrost relay.
※ Purpose of application of above circuit: It aims to interrupt electricity passage through

F, R defrost heater even though F, R defrost relay is bad while COMP is operating.

31

8-8) BLDC Motor Operation Circuit Part

■ In case Fan Motor is locked, therefore, when Fan Motor is constrained to less than
about 600rpm in order to prevent over-current to the power source group, PIN #39,
#38 and #37 sense it so that they can stop Fan Motor operation.

If Fan Motor operation is stopped by this function, it becomes to re-operate every 10
second. If Motor Connector is separated under the state where the power source is
applied during service, Micom recognizes it as Fan Motor is constrained so that
Micom can stop Motor. Then Motor resumes to operate after 10 seconds.

However, there are a part of products which re-operate every about 5 minute among
the products which were manufactured in February and March.

Therefore, when the product is completely repaired, confirm the repaired state with

power-ON again after power-OFF if possible.

32

8-9) Various Option Function

■When pressing the temperature control s/w of freezer and vacation s/w for 12 sec.
continuously at the same time, display is converted into option setup mode.

■When display is converted into option setup mode, every display except for
temperature display of freezer and Refrigerator turns off like the following.

■On display like the above, temperature display of Refrigerator indicates items of

option, and temperature display of freezer indicates setup value for each
item.For the temperature display of Refrigerator, when temperature control s/w is
pressed, option items increase, and when vacation s/w is pressed, option items
decrease. For the temperature display of freezer, when temperature control s/w
is pressed, option setup value increases, and when vacation s/w is pressed,
option setup value decreases. If waiting for 20sec. after changing option by
controlling s/w, option setup value is saved to EEPROM, and option setup mode
is canceled automatically and restored normal display. For example, if you want
to shift temperature of Refrigerator by -3℃ by controlling option, follow the
processes of below.

1) Press temperature control s/w and vacation s/w of freezer for more than
12 sec. simultaneously : all displays become off except temperature
display of freezer and Refrigerator.

2) Pressing temperature control s/w of Refrigerator for one time, “1”is
indicated on Refrigerator display : If indication “1”is displayed on
Refrigerator display, it shows temperature setup of Refrigerator, and
current temperature setup value of Refrigerator is indicated on
temperature display of freezer.

3) If temperature display of freezer indicates “9”this time, check value
which is set at present from the table in the next page. In this case,
you can see that temperature is changed to +1.0℃ compared to the
standard temperature according to the table : Here, in order to change
by -3.0℃, (+1.0℃) + (-3℃) = -2.0℃ is calculated.

4) Now Refer to the table on the next page to change temperature to

-2℃. Press temperature s/w and quick freeze s/w of freezer for
temperature control display to indicate “4”: Waiting for 20sec. after
setup, MICOM saves setup value to EEPROM and returns to the
normal display and cancel option setup mode.

33

󳢬Caution

When product is delivered, option function is set to EEPROM from the plant,
therefore, Refrain from intentional change except for special case. Option
function setup is completed only after it is returned to the normal display after
20sec.. So do not turn power off before display returns to the normal state.

1. If each EVA-SENSOR of F room and R room has open or short-related defect, electricity
does not flow to defrost heater and it returns to normal operation after pause time passes.
Therefore, if the period when defrost heater does not work accumulates, Refrigerating and
freezing badness results.

2. If temperature fuse which is a safety device is turned off, or defrost heater has wire
disconnection, or relay on PCB is bad, defrost is done by natural temperature rise. In this
case, period of COMP off according to defrost becomes very long so that badness on
Refrigerating and freezing function results.

9-6) When FAN does not work

“Check cooling fan only at the condition of selecting forced operation necessarily.”

1. When COMP is turned off, cooling fan of freezer(F-FAN), cooling fan of Refrigerator(R-FAN),
COMP, and cooling fan of COMP mostly retains “off”state. However, in case of R-FAN, it can

operate for some period of time by natural defrost function if COMP is turned off.(It operates
depending on temperature condition of Refrigerator)

2. Evenat forced operation condition, R-FAN is not always turned on (including normal operation),
and retains “off”state if temperature of Refrigerator room is reached the set temperature.

3. When the door of freezer and Refrigerator is closed after opening, each fan has its delay time. That
is, fan stops immediately when door is opened during its operation, and operates again after
delay of about 10sec. or 1min. (when outer temperature is over 35℃) when the door is closed.

10. Operation Principle & Repair Method of ICE-MAKER

10-1) Operation Principle of ICE-MAKER

52

10-2) Ice-maker Test Function

5. Test Function

●It is function for the case which needs forced motion for the purpose of cleaning and
so on at the time of operation test and A/S. This function is performed when the test
s/w which is equipped with the body of automatic ice-maker itself, is pressed for
more than 1.5 sec..

1) Test button does not go into test function during ice-eject, levelling for horizontal
position and water supply. It operates in the horizontal state. It does not operate at
the state where ice is fully filled. Only after ice full mode is cancelled and ice-check
s/w is off, test function operates.

2) When test button is pressed in the horizontal state for more than 1.5sec., ice-eject
motion starts immediately regardless of conditions of ice-making
container. Therefore, if test function operates in the state where water does not
freeze yet, water may be poured. So, care should be taken. After ice-eject motion,
1cycle of water supply is carried out in horizontal levelling movement. Therefore, the
problems of ice-eject movement, horizontal levelling movement, and water supply
can be checked by the test button. At this time, when the test function operates
normally, buzzer sound “Ding-Dong” occurs and starts water supply function. Hence,
if buzzer sound “Ding-Dong” doesn’t occur, it may be considered that there is some
abnormality so that check and repair are indispensable.

3)When water supply is finished, it operates in normal cycle of ice-making→

ice-eject→ horizontal restoration→ water supply in order.

<Case Where Test Function does not Work>

6. Function according to F-Room Door Open

●This is function to minimize noise occurrence by stopping operation basically
when door F-room opens.

1) If F-room door opens while ice-eject or horizontal levelling is working, the function
stops immediately at this point of time. When the door is closed, function operates
normally.

2) In case water is being supplied, normal function is performed regardless of door
open of F-room.

3) Accordingly, when F-room door is opened to check, if tray leans or its angle deviates
from horizontal position, it is considered that it stops during ice-eject or horizontal
levelling movement. It doesn’t matter to judge it as a defect if it is not in horizontal
position after more than 30sec. passes when F-room door is closed to keep
horizontal state after water supply. In case it stops by F-room door open while it is
operating, Test function doesn’t work because it is actually working. So, after
finishing water supply, test function operates.

10-3) ICE-MAKER Circuit Part (Limited to equipped model)

Above ice-maker circuit is one about a kit which is equipped at the freezer. Water
supply to ice-making container is performed by operating AC solenoid which is
located in the machine room through relay so that water is supplied by open/close
time of valve. This circuit is H/W for embodiment of functions such as eject of ice­making container, horizontal levelling, ice-making temperature sensing and full-ice
sensing. Temperature sensing part is identical to that of the main H/W, and
horizontal(Hor/Inv) S/W, Ice-check(Lever) S/W and sensing circuit are identical to
those of the main H/W. So, explanation about this is omitted here, and only ice-eject
motor driving circuit part is explained.
When rotating motor in the counter-clockwise direction(CCW), if signal of
Micom Port No #10 is outputted to High. When pressure of IC05 is applied,
the voltage is applied of +12V by output of IC05 17, and the current is supplied to
IC04 of ⑪ through motor. At this time, ⑥ terminal of IC04 is connected with CCW
Port together so that output port of the corresponding IC04 ⑪ is turned on.
Therefore, current flows to the ground and motor rotates inversely.
When it moves to clockwise direction(CW), CW Port #9 is outputted by “HIGH”. The
functions of ice-eject and horizontal levelling are performed by the operation of IC
Port through right direction rotation movement.
For the points related with operation of above circuit, refer to the explanation of ice­maker function of our SVC Manual.

54

10-5) Operation of Ice-Maker

1. Connect the water-supply line to the supplying valve of the refrigerator to
supply water.(See the water tube connection procedure)

2. Push bucket to the end so that guide-ice of ice-maker is not in contact with the
end of bucket.(If the end of bucket is in contact with the guide-ice of the ice-maker,
the ice-maker will determine that there is enough ice and does not make ice
thereafter.)

3. With a newly installed refrigerator, allow about 6 hours for the refrigerator to
make ice normally and discard the made ice several times to remove impurities.

4. To get enough ice stored in the storage bin, use the ice dispenser normally after
operating the ice-maker for about 24 hours.

1. Fit the rear rising of the ICE-MAKER KIT to the front slot of the TRAY ICE.

2. Lift FIXER-CASE at the front of the SUPT-ICE MAKER up. (① direction)

3. Place the top rising of the ICE-MAKER KIT to the slot of SUPT-ICE MAKER for
insertion.

4. Push the front of the ICE-MAKER KIT while maintaining the position.
(Be careful. If you overpush the ICE-MAKER KIT, the fixed rising of the SUPT­ICE MAKER may be damaged.)

5. When the front of the ICE-MAKER KIT is sagging, it means the assembly is not right.
At that case, perform the assembly again.

10-6) Disassembly of Ice Maker

1. Pull out the bucket from the freezer.

2. Disassemble the SUPT-ICE MAKER, which fixes the ice-maker, and the wire housing
in the rear of the maker.

3. Disassemble by lifting the SUPT-ICE and FIXER-CASE in the front of the maker up
(① direction) and pulling the ICE-MAKER KIT out to the front (② direction).(Do not
disassemble each component of the ICE-MAKER KIT. Otherwise, the setting value
may be changed.)

Reference No. 3) Load Defect Checkup

After separating power cord from power
source plug socket, separate connectors
CN10, 70, and 71 of the main PCB, and
check the following items.

1. Measure load terminal and resistance value
between terminals like the following to check
whether there may exist defects of load and
electric wire connection.

Note) COMP parts can be changed by Capacitor, PTC, and Over Load Protector. Therefore, they

are checked by existence of movement.

(R-Room Lamp Part)

1. When refrigerator door is opened, check whether lamp is lit up or not. If it is normal,
check whether lamp lights out or not when pressing DOOR S/W in the state that R­DOOR is open. If any faults are found, check DOOR S/W of R-ROOM door.

(MAIN-PCB Sensing Part for R-ROOM Door Open )

1.Check voltage by applying “+” terminal to CN30 and “-” terminal to .

2. When R-ROOM door is opened, if about DC 5V is measured, it is normal.

3. When R-ROOM door is closed, if about DC 0V is measured, it is normal. If any faults
are found, check DOOR S/W and wire connection system.

(F-Room Lamp Part)

1. When freezer door is opened, check whether lamp is lit up or not. If it is normal, check
whether lamp lights out or not when pressing door S/W in the state that F-DOOR is
open. If any faults are found, check door S/W of F-ROOM door.

(MAIN-PCB Sensing Part for F-ROOM Door Open )

1.Check voltage by applying “+” terminal to CN30 and “-” terminal to .

2. When F-ROOM door is opened, if about DC 5V is measured, it is normal.

3. When F-ROOM door is closed, if about DC 0V is measured, it is normal. If any faults
are found, check DOOR S/W and wire connection system.

(Ice Eject Lever)

1. In case ice is not ejected though ice eject lever which is installed at the front part of
freezer, check like the following.

2. First, check fault existence of F-ROOM DOOR S/W. If no defect is found, separate
CN31 connector on the MAIN-PCB. Apply “+” terminal to and “-” terminal to, and check
resistance. Check it becomes 0Ω when ICE LEVER S/W was pressed. When it is
always ∞ regardless of ON/Off of S/W, check wire system and connection system.

Set the number to desired number, two digit, as reght table.

4. Setting the option and data, please wait until control panel is changed to the control mode
automatically.

5. If the option control is completed, check the amount of supplied water in the Ice Maker.

If the controlled amount of water supply is slightly below the optimum level, it is O.K. to use.

2) When the test button is pressed, the ice cube container is turned and then water is
out from the tap of the ice maker where water is supplied. At this time, check the
amount of water.(see the picture)
If there is over-supply of water, the ice cube will be made in attached form of 2 to
4 ice cubes. If there is less-supply of water, the ice cube will be made in small size.
When this happens, you may encounter inconvenience while using. This is not a
problem in the refrigerator. It is the problem of water pressure in the water pipe
and occurs frequrently. When this problem occurs, control the amount of water
supply by the following method.

18. Installation of the water dispenser line

1) For automatic operation of the ice maker, water pressure of 1.4~4.5

㎏f/㎠

is required.(It is

acceptable if the disposable paper cup(180cc) can be filled up with water within 10 second.)

2) The water tube can be used by cutting to the desired length. Make sure that the tube is not
bent.

3) Make the maximum length of the water tube to be 12m, if possible. If the length is over 12m,
it will cause a problem to supply water because of decrease of water pressure.

4) Locate the water tube at the area without heat.

5) The purifier is just for filtration. It will not work as sterilizer of microorganisms.

6) If the refrigerator is installed in the area with low water pressure(below 1.4

㎏f/㎠

),
additionally purchased booster pump may be installed in order to compensate the shortage
of pressure.

7) The life cycle of purifier depends upon the condition of the usage, but we recommend that
you change it every 6 months. So we recommend that you install it at the place to access
easily for changing.

8) To supply water to the storage tank inside the refrigerator, press the cold water button for
about 2 or 3 minutes and make cold water drop from the cold water outlet.

9) In order to avid possible leakage, seal every joined area using sealing tape.

10) The water tube should be connecfed to the cold tap water.

■

Check the components

1. Connect coupler to the water tap.

1) Close the main water tap.

2) Connect the coupler to the tap water.

3) Every joint should be taped with sealing
tape.(see the picture)

❇

If the coupler doesn’t fit to

the existing water tap, consult the
closest authorized service dealer and
purchase the right couplers for the
proper installation.

2. Connect the water tube to the conpler

Insert the waterfube into the conpler.

The water tube should be connected
to the cold water pipe. If it is connected
to the hol water pipe, it may cause
some problems in the Functioning of
the purifler.

PRECATUTION!

6. Fix the purifier.

1) Fix the purifier as shown int he
picture on the right.

3. Select the purifier location for installation

1) Select the location of the purifier.

2) Cut water tube considering the
distances between Purifier and
waterworks tap, and Purifier and
water valve of Refrigerator
(At this time, it must be cut at a

reght angle.)

3) Insert water tubes of inlet side and
outlet side of Purifier.

4. Remove the residuals inside the purifies.

1) Open the main water valve to
check whether water is running
through the water tube from the
water inlet side of the purifier.

2) Leave the faucet open until clean
water is running out.

5. Fix the purifier lock station.

1) Hold the purifier lock station
against the lock hole of right­lower side in the back of the
refrigerator and fix it tightly
using screw.

7. Connect the water tube to the refrigerator.

1) Remove the back cover of
the refrigerator.

2) Connect the water tube to
the valve as shown in
the picture.(The connector is
located at right side of the
machine room in the back of
the refrigerator.)

3) When connected, check
whether there is any leakage.
On leakage, reassemble them.

8. Put the water tube in order

1) Using the clip ”A” and ”B” fix
the water tube to the wall.

2) When the water tube is put in
order, make sure there are any
forced bending and pushing
against the water tube.

9. Complete the installation of the water dispenser line

1) Turn on the refrigerator and press
the left side lever until water is
coming out through the water
tube.(approximately 2~3minute)
(Press it until the initial air outing
phenomenon disappear.)

2) At this time, check any possible
leakage on the joints of the water
tube. After putting the water
tube in order, move the refrigerator
to the desired location. Once the
refrigerator is located, do not move
the refrigerator as possible.
