3. OPERATION 3-1. Explanation Of Each Function 1. Function (1) When the appliance is plugged in, it is set to 37 °F for the refrigerator and 0 °F for the freezer. You can adjust the refrigerator and the freezer control temperature by pressing the ADJUST button. (2) When the power is initially applied or restored after a power failure, maintains its previously set temperature.
5. Ice Plus Selection Please select this function for quick freezing. (1) The ICE PLUS option starts counting its 24-hours period every time the button is pressed. (2) The ICE PLUS function automatically turns off after twenty-four hours pass. 6. Dispenser Use Selection You can select water or ice.
11. Ice Plus (1) The purpose of this function is to intensify the cooling speed of freezer and to increase the amount of ice. (2) Whenever selection switch is pressed, selection/release, the LED will turn ON or OFF. (3) If there is a power outage and the refrigerator is powered on again, Ice Plus will be canceled. (4) To activate this function, press the Ice Plus key and the LED will turn ON.
14. Defrosting (removing frost) (1) Defrosting starts each time the COMPRESSOR running time reaches 7 hours. (2) For initial power on or for restoring power, defrosting starts when the compressor running time reaches 4 hours. (3) Defrosting stops if the sensor temperature reaches 46.4°F (8°C) or more. If the sensor doesn’t reach 46.4°F (8°C) in 2 hours, the defrost mode is malfunctioning.
3-2. Ice Maker Function 1. Operation Principle of icemaker Power On Start Position • Adjusts EJECTOR to Start Position with power on. Icemaking • Waits until water becomes ICE after starting the Mode icemaking operation. Harvest • Runs MOTOR to drop ice from the tray into the ICE BIN. Mode (During harvest mode, check if the ice bin is full.) Park Position...
2. Icemaking Mode (1) Icemaking refers to the freezing of supplied water in the ice tray. Complete freezing is assured by measuring the temperature of the tray with Icemaking SENSOR. (2) Icemaking starts after completion of the water fill operation. (3) The icemaking function is completed when the sensor reaches 1 9 °∆F (-7 °∆C), 55 minutes after starting.
5. Function TEST (1) This is a forced operation for test, service, cleaning, etc. It is operated by pressing and holding the cube size button for 3 seconds. (2) The test works only in the Icemaking Mode. It cannot be entered from the Harvest or Fill mode. (3) Caution! Caution! Caution! Caution! If the test is performed before water in the icemaker is frozen, the ejector will pass through the water.
5. ADJUSTMENT 5-1. Compressor 1. Role The compressor intakes low temperature and low pressure gas from the evaporator of the refrigerator and compresses this gas to high-temperature and high-pressure gas. It then delivers the gas to the condenser. 2. Composition The compressor includes overload protection.
4. diagnosis (Rated Voltage Remove PTC-Starter Power Source. ±10%)? from Compressor and measure voltage between Terminal C of Compressor and Terminal 5 or 6 of PTC. OLP disconnected? No Voltage. Replace OLP. Check connection condition. Reconnect. Applied voltage isn't Advise customer that in acceptable range.
5-2. Positive Temperature Coefficient (PTC) – Starter 1. Composition (1) PTC (Positive Temperature Coefficient) is a no-contact semiconductor starting device which uses ceramic material consisting of BaTiO3. (2) The higher the temperature is, the higher the resistance value. These features are used as a starting device for the motor.
5-3. Over Load Protector (OLP) 1. Define (1) The OLP (OVERLOAD PROTECTOR) is attached to the Compressor and protects the motor by opening the circuit to the motor if the temperature rises and activating the bimetal spring in the OLP. (2) When high current flows to the compressor motor, the Bimetal works by heating the heater inside the OLP, and the OLP protects the Motor by cutting off the current flowing to the Compressor Motor.
