1) For starters, be sure to check any chances of the leakage of electricity.
2) You could handle a part in the vicinity of electricity after unplugging.
3) You should put on rubber gloves to prevent an electric shock on operation test.
4) Make sure the rated current, voltage, capacity before using an instrument.
5) Keep your wet hands away from the metal goods in the freezer compartment not to be frostbitten.
6) Be careful not to let water to permeate the electric part in the machine room.
7) With the door open during your repair, you might be hurt by that door.

1) Total Run-time of COMP : 6, 8, 10, 12, 14 hours
2) Running-rate of COMP (each 2hours running-rate) : more than 80%
3) Total time of Door openings : 10minutes
4) Total Time (COMP-On + COMP-Off) : 60hours
5) Ambient Temperature : more than 35
6) In each Error : R1, F1, D1, F3, RT-S, Door-SW Error
2. Terms to start Defrosting Period
1) The Defrosting starts with the following conditions, in case total
COMP-run time passes 6, 8, 10 or 12hours
¨ çwhen an Error occurs
¨ èwhen running-rate of COMP is more than 80%
¨ éwhen total Door-opening time is more than 10minutes
¨ êwhen the ambient temperature is more than 35
2) Defrosting starts unconditionally when total COMP-run time passes
14 hours, under the condition that terms of 1) are not satisfied.
3) Defrosting starts immediately when Total-time (COMP-On + Off time)
is more than 60 hours, under the condition that terms of 1) and/or 2)
are not satisfied.

C-LED of F-PCB) 1. Custom-LED 1. How to start ; open and close refrigerator door 3 times while pressing REF.SET Button and it starts after 3 seconds.
2. Display
If any error, characters(Bar-LED) of C-LED are lit.
In Error Display Mode, the Buzzer beeps in short interval - every
0.1second at 5seconds cycle.
3. How to finish : doing above 1 again.
4. It ends by itself 4 minutes after start.
5. All the Error Code is reset by itself when it returns to normal state.
6. Error Code
7. Error Control
1) F1 Error
Occurrence ; in case of F-Sensor disconnection/short-circuit
Control ; let COMP and F-Fan On for 40min., Off for 20min.
Dissolution ; if F-Sensor is in normal state, it is finished by itself.
2) r1 Error
Occurrence : in case of R-Sensor disconnection/short-circuit
Control it in accordance as ambient temperature.
Dissolution : if R-Sensor is in normal state, it is finished by itself.
3) rt Error
Occurrence : RT-Sensor disconnection/short-circuit
Control : deletion of control-condition by RT-Sensor
Dissolution : if RT-Sensor is in normal state, it is finished by itself.
Limit-time : 4min.
Check error with-
out using jig.

4) d1 Error
Occurrence : D-Sensor disconnection/short-circuit
Control : by limit time(40min.) of Defrosting-return
Dissolution : if D-Sensor is in normal state, it is finished by itself.
5) door Error
Occurrence : when door-opening is sensed for more than 1 hour
Control : deletion of Door SW sensing function
Dissolution : if Door SW open-close is sensed, it ends by itself.
Display dissolution : after Custom LED Display Mode
(Door SW should be in normal state if Error Display Mode is to start.)
6) C1 Error
Occurrence : when COMP runs continuously for more than
3 hours while D-Sensor is above -5
Control : normal running
Dissolution : when D-Sensor temperature is below -5 while
Comp is Off
7) F3 Error
Occurrence : by limit time of 80min. at defrosting-return
Control : deletion of Pre-cool mode at defrosting mode
Dissolution : the end of defrosting is done by D-Sensor
8Forced Defrosting 1. Defrosting Mode A/S (Heater) Forced Defrosting
1. Start : press REF.SET Button 5 times while pressing FRZ.SET Button
(It is impossible in the state of Energy Consumption Forced Defrosting.)
2. Process
1) Let Heater On for 30seconds.
2) Delete Pre-cool of normal defrosting mode.
3. Heater turns Off when D-Sensor temperature is more than 10,
30 seconds after Heater On.

11 Explanation after Delivery Electric Devices 1. Start : press both buttons for 3 seconds after initial power supply
(plug-in).
2. Electric devices turn Off for 3 hours.
3. Display works in normal way.
12 Prevention of COMP Restart COMP 1. COMP does not restart for 6 minutes after COMP Off, though F-Sensor
turns On. 6min. delay
13 Buzzer Alarm Buzzer 1. Buzzer rings by pressing F-PCB Buttons.
2. Buzzer rings for 1 second after initial power supply (plug-in).
3. Buzzer rings for 1 second at the start of A/S Forced Defrosting.
4. Buzzer rings every 1 minute after door opening.
(It rings within 5minutes and ring-time is prolonged as time passes.)
5. Buzzer makes short ring every 5 seconds in Error Display.
14 Demonstration Function Electric Devices 1. Start : open and close Refrigerator[Freshfood Compartment] Door
5 times while pressing FRZ.SET Button.
2. Control
1) Electric devices turn Off except for F-Fan and R-Fan.
2) Fan Control
3. Dissolution :
1) Open and close Refrigerator[Freshfood Compartment] Door 5 times
while pressing REF.SET Button in Demonstration mode.
2) Supply the power again(plug-out and plug-in)
15 Control of R-Sensor Off-
Point 1. Control Resistance of R-Sensor “ 2”
Off-point
1. In case of Weak-refrigeration (though R-Fan and COMP work on and
on), the following actions are to be done.
2. Resistance R13 : Control Resistance of R-Sensor Middle(“ 2” ) Off-point
(- 1.0 , 31.4 )
3. Resistance R14 : reduceing R-Sensor Resistance by 1.5¡ Éin case
of weak-Refrigeration (-2.5 , 2.15 )
4. SW1 : during A/S, if SW1 is opened, R-Sensor Middle Off-point
decreases by 1.5 .
