• The resistance of SENSOR has ±5% common difference.
• Measure the resistance of SENSOR after leaving it over 3 minutes in measuring temperature.

This postponing is necessary because of perceiving speed.

• Measure the F-SENSOR, SUPER FROST SENSOR, R1, R2-SENSOR after disconnect CON5 of PWB ASSY, MAIN.

1. This feature is to shorten the cooling time of the refrigerator by keeping the comp, fan running for a while. When the

Super Cool button is pushed, the Super Cool LED turns on in order and the comp keeps on running. In 2 hours, the
Super Cool mode will be cleared.

2. When the Defrosting mode starts while in the Super Cool mode, defrosting is performed.  After that, the Super Cool mode

resumes for the remaining time.

3. When the Super Cool button is pushed while in the Defrosting mode, the Super Cool mode starts in 7 minutes after the

completion of the defrosting even though the Super Cool LED turns on.

4. If a power failure occurs while in the Super Cool mode, the Super Cool mode will be cancelled when the power is

restored.

5. If the Super Cool mode is selected when it has not passed 7 minutes since the comp stopped, the comp will start running

after the remaining time elapses.

6. In Super Cool mode, Freezer fan motor operates with 1750 RPM.

1. For 2 minutes while the door of the freezer or the refrigerator is open or after it is

closed, the LED turns on in the order of       ,

and then the all LEDs are kept on.

2. While the LED turns on as described above, the sensor detects the location of the

food and so on.

1. Fan motor in the freezer compartment shall change from standard to high speed rpm in order to increase cooling speed

and load corresponding speed.

2. Hign speed rpm is only used for the initial power application, super cool mode and load corresponding operation. But

standard rpm is used in the general working conditions.

3. When the door of freezer room or refrigerator room is opened, the FAN MOTOR is stoped immediately, then when the

door is closed, the FAN DOOR is operated.

1. This feature is to alarm by the buzzer when the door of the freezer or the refrigerator is not closed in 1 minute after it is

opened.

2. In 1 minute after the door is opened, the buzzer sounds three times at the interval of 0.5 second.  After that, every 30

seconds, the buzzer sounds three times with 0.5 sec ON/OFF.

3. The alarming is cancelled when the door of the freezer or the refrigerator is closed while the buzzer sounds.

1. When the button on the front Display is pushed, “Ding-” sound is produced and it works as follows.

1. To raise the refrigerating speed, fan motor in the refrigerator compartment is operated when the door of freezer room or

refrigerator room is opened and then closed.

2. The fan motor is stoped after 20 sec. when the door is closed.

1. The defrosting is performed each time when the total running time of the compressor reaches 7 hours.

2. After the power is turned on (or restored after a power failure), the defrosting starts when the total running time of the

compressor reaches 4 hours.

3. When the temperature of the defrosting sensor reaches 10 °C or above, the defrosting stops.  If the temperature does not

reach 10 °C in 2 hours after the defrosting starts, the defrosting error code is displayed. 
(Refer to 7-1-10. Error Diagnostic Mode.)

4. With the defective defrosting sensor (cut or short-circuited wire), the defrosting will not be performed.

The electric components, such as the comp, defrosting heater, and cooling fan, start sequentially to avoid the noise and
damage to the part, which may result from the simultaneous start of various components on turning the power on or after
the completion of a test.

If the temp of the defrosting 
sensor is 45 °C or above
(For the initial use after the 
purchase or grounding)

If the temp of the defrosting 
sensor is below 45 °C
(After a power failure or SVC)
