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
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.
? 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
Refrigerator.
5) At this time, beep alarm also sounds for 3sec. at the point of defrost, and
0.75sec. ON/ 0.25sec. off sound occurs continually until simultaneous
defrost of F and R is completed.
? Test Cancel Mode
1) In the state of simultaneous defrost of freezer and Refrigerator, if display panel
is converted into test mode, and test button is pressed once more, defrost
of both freezer and Refrigeration is cancelled immediately and resumes
normal operation .

? Reference
It works step by step in test function. It does not change from 1 step
(forced operation) to 4 step (test cancel mode) directly. It operates
corresponding function only after it goes through the previous step. While
test function works, it is most desirable to turn off main power and then turn it on.
7-7) Self-diagnosis Function
Self-diagnosis Function at the time of initial power is on.
1) When the initial power is applied to Refrigerator, all lamps light and conduct
self-diagnosis function internally.
2) If result shows no fault, display will go into the initial normal lighting state.
3) If result shows any fault, corresponding led is turned on and off and alarm
sounds.
4) Error sign of self-diagnosis continues until all defects of parts are repaired
or self-checkup function is cancelled.
5) If all corresponding parts are repaired completely, display will go into the
normal mode state.
6) After repairing Refrigerator, turn on switch again after turning it off to
make it sure if Refrigerator is properly repaired.
7) Therefore, in case open & short related problem of sensor needs to be
confirmed during A/S, turn off the power of Refrigerator and turned it on
again to operate self-Diagnosis function. Then sensor function can be
checked.
When any defect occurs, corresponding display signs are shown as in the
following chart.
21Note) This self-Diagnosis works only when the open/short related aspect of sensor is bad. Minute
feature change of sensor is not judged as defect if it does not get rid of the extent of temperature
sensor described in Remark so that it is indicated as normal.
? 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.
