7. TEMPERATURE CONTROL AND THE OTHERS 7-1. ELECTRONIC MODE 1. DISPLAY DESIGN 2. Temperature control function 1) Freezer temperatur control 1-1) It consists of five steps as follows and selected by one button. MID → MID,HIGH → NIGH → LOW → LOW,MID 1-2) setting up turn on a light in order by system of freezer cholce button. ( MID → MID,HIGH → NIGH → LOW → LOW,MID → MID...) 1-3) It set up“MID”automaticature during power on. 1-4) There is standard temperatically list of each notch part.
3-1) Power freeze function A. Input power freeze/regular condetion key. When power freeze startes, LED signal change at once. (Comp and F-fan runs continuously for two and a half hours when quick freeze sekected.) B. During quick freezing the refrigerator controlled by setted notch. 3-2) Regular condition function A. Judge the temp. of F/R room, F room is over comp on of“LOW”NOTCH or R room is over comp on of“LOW”NOTCH. If so regular condition function isn’t performed and LED is OFF below 0.5 seconds. B.
3) Forced operating and defrosting“Beep” ( sound) 3-1) If forced function selected the“Beep”sounds. 3-2) Alarming sounds until the forced operating canceled by automatically(24Hr) or manualy. 3-3) Alarming sounds until the forced defrosting canceled by automatiically(24Hr) or manualy. 4) Defrosting 1-1) From the first power on, defrosting started after 4 hours of total Comp on time. 1-2) After that defrosting cycle can be varied from 6 hours to 24 hours.
5. SELF DIAGNOSIS 1) SELF DIAGNOSIS AT FIRST POWER ON 1-1) As the power applied to the refrigerator first time, all dispays show operating and run the self diagnosis. 1-2) If no problem foundes, display returns to normal mode 1-3) If probiem foundes, on and off the related display lamp and start alarming. 1-4) Lamp displayed until the problem solved or seif diagnosis cancelled. 1-5) After problem solved the display mode return to nomal.
6. LOAD STATUS DISPLAY 1) Press power freezing / regular conditing and power refrigerating / power saving key for five seconds then press temperature control key in the refrigerator after temperature display lamps on and off three times 2) This mode shows which lamps is being sourced signal from MICOM currently. This doesn’t mean the load is operate due to the open wire or relay missing though the display shows the compressor operating. 3) Load status display return to normal mode after sixty seconds.
7. operating of fan motor 1) FAN MOTORoperates BLDC MOTOR by dc power. 2) After first starting power, it operates“HIGH”rpm to off dot of fan and then operates“LOW”rpm 3) if binding motor or not sensing regular freguency of motor to pcb, motor will stop operating. (After stopping, reoerating start in 10 seconds.) ※ F, R, C-FAN operate equal. 8.

7-2, SEMI ELECTRONIC MODE A. Temperature control part design Freezer temperature control refrigerator temperature control TEMP, FRE TEMP, REF B. Temperature control function 1) Tempera ture choice of freezer ·You can choose to ⑧ From ① ·Follows are control temperature by KNOB position. KNOB position ① ② ③ ④ ⑤ ⑥ ⑦ ⑧ control temperature -16.0 -17.0 -18.0 -19.0 -20.0 -21.0 -22.0 -23.
D. TEST FUNCTION ▶ TEST function is function for test,SVC and fair test of PCB and product. ▶ TEST S/W choose and confirm function of product and then POWER ON to run self diagnosis. 1) FORCED OPERATING FUNCTION ● Pressed once TEST S/W on MAIN PCB. If so COMP and F-FAN run at once. Thus be careful because occur COMP over load. (Refrigerator FAN control ON/OFF by temperature) ● Since it set up forced operating function, it always run COMP and F-FAN and display lamp on MAIN PCB with ON/OFF 0.
E. self diagnosis function 1) Power on refrigerator and it run seif diagnosis function about 2 seconds at the inner part. 2) If no preblem it turns normal mode. 3) If find prebiem display lamp of PCB show errw position like lower list and everything don’t operate until repair error position. 4) After refrigerator power off and then power on for confirming conditiom. 5) Thus if you want to know OPEN/SHORT of temperature sensor on SVC, power off and on if it run self diagnosis function.
8. CIRCUIT OPERATING THEORY 8-1. ELECTRONIC MODE 1. Power suooly part 1) Power is on and makes about DC 300V through BD1. 2) TOP S/W is switching the best condition automatically. Electric current run between D and S of TOP S/W and occur electric current in TRANS and when power of D-s is off storing electric current of TRANS pass to secondary voltage. 3) Voltage main 12V. This is applied to display, relay and 5V power of sourcr and Main PCB 2.
1) RESET part is intialize RAM of MICOM and others when power is on or power is inferruoted for some time It will make whole program runs from the first status. When power is supplied, reset voltage is“LOW”status for a few seconds and turn into“HIGH”(Vcc Voltage) status in the normal opweating. 4.
5. TEMP·SENSING PART 1) Thermistor is used for sensing which has negative resistance coffiecient to the temperature. R 302, 4, 6, 8, 12, C301~C306 are pares for preventing noise. 2) MICOM input voltage, Vf of sensor is Vf=(R+hx x Vcc)/(R301+Rth) (Rth : sensor resistance) 6.
7. COMP AND DEFROSTING HEATER OPERATING GRY RED COMP LED F-DEFROSTING HEATER R-DEFROSTING HEATER As it is seen above block diagram. 220V line is connected to the commons of comp relay, Ry 71 and defrosting heater relay, Ry 73, Ry 75. When those relays are off state comp and defrosting heater are also off. As comp relay moves to on and AC 220V applied to comp load it starts operating On the other hand defrost heater runs if defrost heater relay moves to on.
8. BLDC MOTOR Operation Circuit 1) Operate description of BLDC MOTOR First, if FAN became before operate condition of FANMOTOR, condition of in the temp. are high temp. more than FAN of recently institutionn NOTCH is operated condition. ex)CONNECTOR CN 70’S third voltage : Input VL, Vcc 5V(Used Diode regard DROP) Perated High RPM V L = Gain * Ei Gain = (R705+R704)/R704 Ei = R703/(R701+R703) * Vcc = (20K + 10K)/10K = 10K/(820 + 10K)*4.4 =3 = 4.07 V L = 4.07*3=12.
1-2) FAN MOTOR IN THE FREEZER (R-FAN) A. If refrigerator’s power is confimated, check the temp. of R-FAN and temp. more than R-FAN ON is operated “HIGH RPM” to sign of MICOM #11PORT. After arrived FANOFF, if FAN is OFF and separatre function of ON/OFF isn’t confimated always MICOM#10PORT is confimate sign and operated “LOW RPM”. B. “HIGH RPM” is determinated the resistance of R706, LOW RPM is determinated the resistance of R707. C.

FOR SAFETY OF SERVICE CAUTION ● Turn off the power of refrigeration when the change and repair of electric control equipment. → Be caful electric shock ● → use the regular parts when change the electric control equipment. check the named MODEL, regular power, regular electric current and movement temp. ● → When repaired, cross line of HARNESS is firm and no dangerous of water infiltration. When the regular force, it isn’t seperate.
