● When turned on, rectified AC voltage which is stepped down on 2nd transformer flows between ① and ③
at about AC 15V, goes through the diode D101 and D104 is changed to DC, and provide constant 12V. It provides 5V to MICOM and other circuits via regulator REG102 (MC7805ACT), and make entire PCB operate. RS2640, RS26VU

OPERATION PRINCIPLES BY PARTS OF CIRCUIT
● When the power is applied,currents will be rectified via B and DC360V will be generated at the both terminals of
the capacitor (C001). The Top-Switch (TNY268P)will be automatically switched to the optimum state according to the secondary load conditions. When currents flow between Top-S/W D and S (5PIN~7PIN),there will be currents generated i n the TRANS and the currents i nduced to the TRANS upon power off between D and S will be transferred to the secondary.By repeating the above process, 12V will be maintained at the secondary C108 and it will be supplied to the display relay. Also, 5V will be generated at the C110 and it will be supplied to the sensor and operate the main PCB.

● It is an Oscillation Circuit for synchronism clock generation and time calculation on the information sending &
receiving of the MICOM internal logic elements and when specifications for Resonator change, the timing system of MICOM changes resulting in errors. (Rated parts must be used)
5-3) RESET CIRCUIT ●
17
RESET Circuit allows the whole program to go back to the initial setting by initializing parts such as the RAM in MICOM with the power supply into MICOM or with an instant power failure. Upon the power supply, the reset terminal voltage becomes "LOW" for several tens of ㎲ compared to Vcc voltage(DC 5V) at MICOM, and it maintains "HIGH"(Vcc Voltage) during normal operation. But, when Vcc drops down to 3.4~3.7V, the reset terminal voltage becomes "LOW".
OPERATION PRINCIPLES BY PARTS OF CIRCUIT 5-4) EEPROM DETECTION CIRCUIT
●
A semiconductor memory EEPROM stores data remembering previous settings regardless of power-off, which are indispensable especially in power fluctuating areas. Also, EEPROM sets and uses other options in principle.
5-5) DOOR SWITCH DETECTON CIRCUIT RS2*3*, RS2*2*, RS2*1*
1) If R-Door is opened, the contact point of the door switch (4-3) becomes open, and the current of PCB line comes through R404 and R405 and provides 5 volt which is recognized as door is opened, and turn off the fan at different load. When the door is closed, the voltage goes out from R404 to Switch, the MICOM is applied with OV and the door is recognized as closed. 2) If F-Door is opened, the contact point of the door switch (4-3) becomes open, and the current of PCB line comes through R402 and R403 and provides 5 volt which is recognized as door is opened, and turn off the fan at different load. When the door is closed, the voltage goes out from R402 to Switch, the MICOM is applied with OV and the door is recognized as closed. 3) Q401 is the circuit to turn off the auger motor operation when the door is opened. If the door is closed, Vcc voltage of R402 works as ground via door switch, OV is applied to the base of Q401, and Q401 becomes operable, Vcc voltage on "A" part Q702 base works as emitter on Q401 collector and creates OV. (Check the operable condition for other parts at load terminals) 4) Condition for door open is the opposite of condition 3 above.

1) Sensor uses a thermistor which has a temp coefficient of negative resistance and controls resistance. When the heat goes up, the resistance gets down and vice versa. R302, 4, 6, 9 and C301~C303, C305 are parts for noise prevention but they are not related to temp sensing characteristics. 2) If Vf is the incoming voltage to MICOM in case of F-Sensor, Vf equals (Rth * Vcc)/ ((R301 + Rth). Where Rth is resistance of THERMISTOR corresponding to Temp. Please refer to the Appendix Temp-to-Sensor Resistance/Voltage conversion table(Temp-to-MICOM Terminal Voltage included) on A/S.

OPERATION PRINCIPLES BY PARTS OF CIRCUIT 5-7) DAMPER CIRCUIT RS2*3*, RS2*2*, RS2*1*
1) The temperature of R-room is controlled by opening and closing of damper with stepping motor, supplying & blocking cold air. 2) TA7774P (IC07) operates the damper. TA7774P is the driver IC only for step motor. If the regular signal is provided to TA7774P from Micom, send combined signal to Quad-Polar step motor to rotate on certain direction. This makes clockwise or counter clockwise rotation to make the damper open or close. 3) Since the damper always touches the cold air, DC 12V/1W heater is installed, always on to prevent the malfunction from moisture and is controlled on conditions. (Operation conditions can be changed). Micon #15 pin connected to IC4 controls the damper heater like category 3. RS2640, RS26VU

(Operation conditions can be changed). Micon #15 pin connected to IC03 controls the damper heater like category 3. 4) The R407 and the R413 are to detect the damper heater open. When the circuit is open, the self diagnosis will display it.(When the initial power is applied, the distributed voltage of DC4.8V will be applied to the MICOM PORT #48.)
5-8) DISPLAY Circuit 1) KEY SCAN When Grid #6 is output, this signal goes through PCB resistance 10 ㏀ and provided to power frequency. When the switch is pressed, R502(6.8 ㏀) and R501 (12 ㏀) decrease the signal and less than 5.1V peak to peak signal is provided to MICOM, the MICOM recognizes the grid #6 is provided, and change the function corresponding to switch key. [Refer the circuit diagram below]
23
OPERATION PRINCIPLES BY PARTS OF CIRCUIT 2) DISPLAY OPERATION Like the signal diagram below, Micom sends “ high ” signal through MICOM 6 terminals of NO #1→ 2 → 3 → 4 → 5 → 6 for 2ms every 12ms. This signal goes to output terminal via input terminal of IC5 (KID65783AP or TD62783AP). Output wave always goes through LED input terminal with DC11~12V on every period. At this time, if SINK signal comes out at IC4, DC11~ 12V is applied to LED input terminal and output terminal sinks to OV which turn on LED for 2ms For example, to turn on "Power Fre." LED, IC4 #16 pin sinks to 0V when IC5 #16 becomes DC 11~12V making "Power Fre" LED turn on. GRID WAVE PATTERN
5-9) Load Control Circuit RS2*3*, RS2*2*, RS2*1*
24
OPERATION PRINCIPLES BY PARTS OF CIRCUIT RS2640, RS26VU
1) Main PCB processes most of the load control for electronic refrigerators. 2) Compressor, F-Room, defrost heater, and other functions are controlled with relay. 3) For example, to operate compressor, MICOM 29 pin outputs high (5V) signal which goes into IC3 Pin #4. The IC3 pin NO 4 plays the same role as the base of NPN TR. The pin #14 works as collector of TR. So, if 5V is supplied to pin #4 of IC3, the pin #15 turned on and connected to the ground. Then, the relay RY75 and coil connected to the pin #15 of IC3 becomes low (OV) and +12V (opposite side of coil) flows to the pin #15 of IC3 via coil and goes into the ground. While current flows to the coil, the magnetic power arise, it turns on the secondary contact point inside of RY75, and operates when the AC power is supplied to the both side of comp. When MICOM #29 Pin becomes Low(0V), IC3 #4 Pin becomes Low which makes Power cut and current of RY75 RELAY cut. So, secondary contact becomes off due to magnetic field cut, which makes Comp off. 4) All other loads work basically on same principle, defrost heater operates only on the condition that the compressor is turned off like the circuit above, and connected like the equivalent circuit below. * Q702 is connected to the F door switch to prevent PL accident due to continuous operation of motor when the auger motor control circuit is not working properly. It must be turned off when the door is opened.

OPERATION PRINCIPLES BY PARTS OF CIRCUIT 5-10) ICE MAKER OPERATION CIRCUIT
1) The ice maker circuit above is to control the ice maker kit installed on the F room. 2) This circuit is the hardware to control ejection and horizontal positioning, ice making temperature detection and full icing detection. Temperature detection circuit is the same as temperature detection circuit on 4-6 and the explanation will be skipped and only the ejection circuit will be explained. If MICOM PORT #7 is outputted with High to rotate motor in ejection direction and the pin #2 of IC5 is inputted, 12V is outputted on pin #17 of IC5, goes to motor and supplied to pin #11 of IC4. As pin #8 of IC4 and eject MICOM port #7 are connected in common, 11 output port of IC4 gets on and the current flows into Ground making motor rotates. This motor rotates the gear and rotates the ejection tray. The tray twists to separate the ice from the tray and return to the horizontal state. 3) For restoration, motor stops for 2 seconds when the ejection is completed and to rotate in opposite direction, output horizontal MICOM port with high and perform horizontal positioning. 4) The test S/W is off in normal cases and MICOM PORT 63 stays high. When necessary, press the switch for more than 1.5 seconds making forced ejection executed. Full S/W has a lever that detects the amount of ice on ice-maker kit and based on the status of MICRO S/W connected to the lever, if the ice is full on the container, ejection is not executed, and only if it is off (MICOM PORT 61 is high), the ejection is executed.

OPERATION PRINCIPLES BY PARTS OF CIRCUIT 5-12) BLDC MOTOR Circuit(RS2640, RS26VU)
1) This model has adopted a BLDC motor to reduce power consumptions and it is used for all of the F-Room, the R-Room and the Unit Compartment. (This motor driving circuit is the common circuit used in other models.) 2) Operation Principle Look at the above circuit. Then, it is quite obvious that the composition of the circuit is similar to one another. Let’s take the F-Fan motor as an example. The Fan Motor operates in high or low speed according to conditions. For the F-Fan to operate, a constant voltage should be applied to OP-AMP PIN #2 as shown in the figure. When the voltage of MICOM #47 is 0V, the voltages of both its counter part and OP-AMP #2 are 0V. So, the motor does not operate. When #47 becomes high (5V), the distributed voltage between R706 and R705, which can be obtained by subtracting the forward direction drop voltage of the D706 (1N4148), will be applied to OP-AMP #2. When this voltage is multiplied three (Gain Value set at present), you can get the voltage applied to the motor. If the voltage of the OP-AMP #13 is 3V, the 9V (3Vx3) is applied to the motor. (When the F-Fan is under High RPM conditions, the MICOM Pin #47 will be high (5V) and when the F-Fan is under Low RPM conditions, the MICOM Pin #46 will be low high(5V). The MICOM Pin does not output High & Low together at the same time. But, it outputs either High or Low, or it outputs all off (0V) and turns off the Fan. (The same principle applies to the High/Low RPM of the C-Fan.) Note) According to conditions, the F-Fan Motor and the Comp Fan Motor will be controlled to HIGH RPM or LOW RPM.In general, it runs in high RPM when the fridge is frequently used and it runs in low RPM when the fridge is being used less frequently. (For the improvement of its function, the RPM, Voltage and Frequency can be changed without any notice in advance.) 3) When error occurs with the motor (when its RPM is detected as lower than 600 ~ 700 RPM), the relevant motor will stop immediately and it will run again in 10 seconds. At this time, if the motor RPM is input correctly, it will be evaluated as normal and keep on its operation. But, if a correct RPM is not input with a start-up after 10 seconds, it will stop and start up again in 10 seconds. When it won't operate normally after repeating stop and start-up for 5 times, it will pause for 10 minutes and then will repeat the 5-time stop & start-up and the 10minute pause. During the above, when the Self Diagnosis is selected on the display panel, it will show that there is an error with the motor by blinking the LED relevant to the motor. When power goes off, data for errors will be deleted. So, do not turn off power before it is checked by our service personnel. Note) When the abnormal operation or stopping of the Fan Motor is expected, do not turn off power. Run the Self Diagnosis and check if there is any error. 28
