7. Function and Usage of Refrigerator 7-1. Panel Display Basic type (NTA) External type (FTA/DTA) 7-2. Temperature-Control function 1. Temperature-Setting Function of Freezer 1) At the first POWER ON, ÒMEDIUMÓ (3rd step) is automatically selected. 2) Select the temperature among five steps, WARMER, (WARMER-MEDIUM), (MEDIUM), (MEDIUM -COLDER), and COLDER by pushing one button.
Notice The specified temperature in the above table, from data when measured in unload state and at 1/3 H inside the room, is only to describe the temperature at each step generally. The actual temperature depends upon the surrounding conditions and the loading state. 7-3. Power-Freezing and Power-Refrigerating Set Power-Freezing and Power-Refrigerating by pushing the separate button.
7-4. ALARM function 1. Button TOUCH sound (ÒDING-DONGÓ sound) 1) If you push each button on the CONTROL PANEL, ÒDING-DONGÓ sounds to confirm the push. 2) If you push two buttons at one time or if you do other wrong-doings, ÒDING-DONGÓ does not sound. 2. DOOR-OPEN alarm (ÒDING-DONGÓ sound) 1) After two minutes with the door of the freezer or the refrigerator opened, alarm sounds ten times. 2) If the door is still in open in spite of the first ten-time alarm, alarm continues 10 times per minute.
7-6. TEST function TEST function is for quality control of PCB and the product, in-process control, and SVC. After check of the function of the product by the selection of TEST S/W, POWER should be turned ON again to perform self-diagnostic function. 1. Forced-Operation function 1) If you select button on MAIN PCB one time, COMP operates immediately without 5-minute DELAY. So, attention should be paid because if you perform Forced-operation at the COMP-OFF time, OVER LOAD may occur.
7-7. Self-Diagnosis Function 1. Self-Diagnosis Function on the first POWER-ON 1) On the first Power-on, lamps are ALL ON and self-diagnosis function operates internally. 2) If there is no fault on the self-diagnosis, DISPLAY will show the first normal state. 3) If there is any fault on the self-diagnosis, the relevant LED will flicker and alarm will sound. 4) ERROR (indicating fault) display by the self-diagnosis will continue till all the relevant problems is fixed or the self-diagnosis is canceled.
2. Self-Diagnosis function during the normal operation 1) If you push buttons for ÒPOWER-FREEZINGÓ and ÒPOWER-REFRIGERATINGÓ simultaneously for about 3 seconds during the normal operation, ALL ON/OFF in the temperature-setting DISPLAY will continue for about 2 seconds at 0.5-second interval. If you push buttons for ÒPOWER-FREEZINGÓ and ÒPOWER-REFRIGERATINGÓ simultaneously for about 5 seconds, including 2 seconds for LED ON/OFF, self-diagnosis function is selected.
No Item Relevant DISPLAY LED 7 Overload condition ÒPOWER-REFRIGERATIONÓ Meaning If the ambient temperature is above 35 Remark , relevant LED ON 8 WARMER-temperature 9 Freezer ÒCOLDERÓ condition (5th step) Normal condition No display LED among 3 MODE displays means If the ambient temperature is below 17 , relevant LED ON Normal operation state Ambient temperature is between 18 and 34 and normal freezing state normal MODE 7-9.
(1) At the moment of selection of stop function, ice-making function stops, but on eject, return to horizontality, and water-supply, stop state will be maintained after finish of water-supply. (2) When OFF function is selected, ice-making function stops. If you push button to select CRUSHED ICE or CUBE ICE, ICE-MAKER will continue to operate from the stop of ice-making. (This means that icemaking function does not operate from the first.

Like the above BLOCK DIAGRAM, LINE of AC 220V is connected to RELAY for COMP and COMMON for HEATER RELAY, respectively. At this time, if RELAY is not operated, contact point is NC state and RDefroster HEATER RELAY is OFF state. So, LOAD maintains OFF state. If COMP becomes the conditions for operation and COMP RELAY is operated (move to contact point NO), COMP becomes closed-circuit and operated and makes power for both ends of F, R-Defroster HEATER OFF state.

8-10. PCB SUB AssÕy (INVERTER PCB) 1. EMI circuit COMMON MODE NOISE is attenuated by CHOKE LFI, NORMAL MODE NOISE and D.C RESISTANCE. 2. Rectifier circuit Holding voltage is converted to DC voltage by BRIDGE DIODE. It is ELECTROLYTIC CAPACITOR and composed of balance circuit 3. First starter circuit The current converted to DC by C2 is charged to C3 through R3.
5. Resonance output circuit To make the life-span of fluorescent light bulb longer, supply the filament pre-heat current. Line current is running through filament C6 RT1 filament C5 PT1. Resistance value is increased at PT1 by running of PTC pre-heat current. When impedance of PT1 is Higher than impedance of C7, the current runs toward C7 and so, discharge voltage is permitted to both ends of lamp. And finally, discharge occurs at lamp as a result of resonance of L and C. C5 PT1.

Safefy Instruction o Service Unplug the refrigerator before making any repair or any replacement. Avoid the electric shock. Use the rated components on the replacement. Check the correct model, rated voltage, rated current, operating temperature and so on. On repair, be sure that the wires such as harness are bundled tightly and are not permeated by water... Bundle tightly wires in order not to be detached by the external force.
