5-1-3. When selecting power on/off function
1. Press the "Lock/Unlock" button for more than 2 seconds to switch to "Unlock" status.
2. At this time, press the "Power" button for more than 2 seconds to turn the power off.
3. At this time, all the LEDs in the display will be turned off with the power off LED turning on.
4. If you press the "Power" button when the power is off, it will turn on the power and recover to "Cabbage Kimchi" and
"Mid".
5. When the power is turned off, the heater of the applicable compartment is turned off and the valve will be closed.
5-1-4. Rhythm fermenting control pattern diagram
1. The fermenting control pattern varies, depending on the temperature of the Kimchi when it is placed into the storage, the
type of Kimchi being made and the degree of the seasoning selected.
2. In the 1st seasoning cycle, if the Kimchi is at room temperature, the cold control operates.
3. During the seasoning cycle, if the Kimchi is cold, the seasoning heater is turned on and if the Kimchi is warm, the
seasoning heater is turned off.(Only 1st seasoning and 2nd seasoning)
4. If a failure occurs, such as a sensor error during seasoning, the storage will default to Cabbage Kimchi storage status.

5-1-5. Temperature control method
1. The compressor runs or stops and the 3-way valve opens or closes depending on the temperature sensed in the left and
right compartment.
2. If the temperature in either compartment is unsatisfactory, the compressor is turned on and the 3-way value is opened to
the affected compartment.
3. If the temperature in both compartments is unsatisfactory, the compressor is turned on and runs until both compartments
become satisfactory. The 3-way valve is opened and closed to each compartment alternatively until the temperature is
satisfactory.
4. During the seasoning cycle, if the temperature is low, the heater is turned on and if the temperature is high, the
compressor is turned on and the 3-way value is opened.
Note1) When the temperature is satisfactory in both compartments, the 3-way valve is open to whichever compartment that
has had a satisfactory temperature most recently.
■ Summary chart of COMP and 3-Way valve operation
5-1-6. Buzzer sound
When you press a button on the front display, you will hear a varying buzzer sound depending on the type and function.
(Refer to Buzzer operating circuit in p21).
5-1-7 Power failure compensation function
1. When the power is restored after an outage, the refrigerator performs the setting originally programmed except for Error
status and Test mode.
2. If the power fails during the seasoning process, there is not power outage compensation function and the storage defaults
to previously set Kimchi type and temperature of "Mid". (to protect excessive seasoning)

5-1-8. Operation in response to ambient temperature
The storage senses the ambient temperature and adjusts the temperature in the compartments accordingly. This keeps the
storage from being too cold or too warm because of seasonal variations and maintains exact temperatures in the
compartments.
5-1-9. Sequential operation of components
Components (compressor, 3-way valve and left/right seasoning heater) are operated in a specific order to prevent damage
and noise caused by simultaneous operation of all parts when the unit is started and after completing the self-test routine.
g Operation order may slightly vary depending on temperature setting.

1. The error diagnosis function is the function to support SVC in case of an error that can affect the performance of the product.
2. If an error occurs, the control panel button will not work.
3. If an error occurs and is resolved, the refrigerator will default to the normal status. (The unit is reset.)
4. The error codes are shown in segment for the remaining seasoning time display of the right compartment, and all LEDs,
except for failure code, are turned off.
Note 1) The failure code is not displayed for the outside temperature sensor failure, but for ‘LED CHECK’ (by pressing and holding “Kimchi
store” button on the left chamber and “Kimchi store” button on the right chamber together for one second or longer). If the outside
temperature sensor is normal, all LEDs are turned ON, but if abnormal, all LEDs are turned ON with the remaining time display on
the right chamber OFF.

5-1-11. Test function
1. The test function checks the functions of the PCB and the refrigerator, searching for errors in parts.
2. The test switch on the PCB operates the test mode. The refrigerator reverts to the normal mode after 2 hours if you forget
to end it manually.
3. When the test mode is active, the buttons on the control panel are disabled but the buzzer still sounds a ding if one is pressed.
4. When the test mode is completed, unplug the refrigerator briefly and plug it in again to reset it and allow normal
operation.
5. If a sensor failure or other failure is detected during the test mode, release the test mode to display the failure code.
6. During the display of the error code, test mode does not work even if you press the Test switch.
LED CHECK function
All LEDs are turned ON by pressing and holding “Kimchi store” button on the left chamber and “Kimchi store” button on the
right chamber together for one second or longer. When these buttons are released, the LED returns to the previous state.

5-2. Circuit description
5-2-1. Power circuit
The power circuit consists of the noise attenuation part and the SMPS (Switch Mode Power Supply) part. The SMPS
consists of the rectifier (BD1 & CE1) to convert AC voltage to DC voltage, switching part (IC3) to switch the converted DC
voltage, transformer to transmit energy of the first side of the switching end to the second side, the secondary power to
supply power to MICOM and IC, and the feedback part (IC4) to feedback the secondary voltage to the first side of the
transformer in order to maintain the secondary voltage constant.
: High voltage (DC 310V) is maintained in this circuit. Wait at least 3 minutes after unplugging to allow the
current to dissipate. There is a danger of electric shock.
5-2-2. Oscillation circuit
The oscillation circuit provides the clock signal for
synchronization and calculation of time in relation
to the logic elements of microprocessor IC1
(MICOM). OSC1 must always use the original
rated parts, because if the specification changes,
the timing generated will not be correct, causing
erratic functioning of the microprocessor.
5-2-3. Reset circuit
The reset circuit allows the entire process to be
started from the initial status by resetting the
various elements within the MICOM (IC1), such as
RAM, whenever power is applied to the unit. Low
voltage is applied to the reset terminal for 10ms at
the beginning of the power input. The reset
terminal has a voltage of 5 V during general
operation. (If the reset operation fails, the
microprocessor will not operate.)

5-2-5. Switch input circuit
The following circuit is the input circuit to detect the test switch signal to check the refrigerator.
5-2-6. Temperature sensor circuit
The following temperature sensor circuit consists of a sensor to detect the outside (ambient) temperature and sensors in the
left and right compartments for storing and seasoning Kimchi. The status of each sensor, whether open or shorted, is shown
below.

5-2-7. Stepping motor operation circuit (3-way valve)
u The motor is operated by sending out "High" and "Low" signals as many as the designated number of steps through
MICOM Pin 15, 16, 17, 18 to rotate the motor through the magnetic field formed by the motor and the coil wrapped
around each stator.
5-2-8. Power failure compensation circuit (located on display PCB)
u The power failure compensation circuit recalls the temperature range of the right and left compartments and maintains
these levels if power if interrupted briefly.
The IC for power failure compensation (EEPROM) delivers to and maintains the information in MICOM through the serial
interface.

5-2-9. Storing temperature compensation and over-cool/under-cool cut compensation circuit
(1) Storing temperature compensation
u This is the circuit to input the temperature compensation level required for adjusting storage temperature at the left or
right compartment.
u Temperature compensation table by adjustment of resistance value (difference against current temperature)
Ex) If you change the resistance of compensation at the left compartment (RCL) from 10KΩ(current resistance) to 18KΩ
(adjusted resistance), the storage temperature in the left compartment will be increased by 1°C.
