COMPRESSOR ELECTRICAL 4-2-3 PTC-Applied Circuit Diagram 4-1 COMPRESSOR •Starting Method for the Motor 4-1-1 Role The compressor intakes low temperature and low pressure gas from the evaporator of the refrigerator and compresses OVERLOAD PROTECTOR this gas to high-temperature and high-pressure gas. It then delivers the gas to the condenser.
4-3 OLP (OVERLOAD PROTECTOR) 4-4 TO REMOVE THE COVER PTC 4-3-1 Definition of OLP 1) Remove the back cover of the mechanical area. (1) OLP (OVERLOAD PROTECTOR) is attached to the compressor and protects the motor by opening the circuit to the motor if the temperature rises activating the bimetal spring in the OLP.

7-2 ICE MAKER FUNCTIONS 7-2-1 Ice Making Mode 1. Icemaking refers to the freezing of supplied water in the ice trays. 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.
7-2-5 Function TEST 1. This is a compulsory 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. (If there is an ERROR, it can only be checked in the TEST mode.) 3.
8. DESCRIPTION OF FUNCTION & CIRCUIT OF MICOM 8-1 FUNCTION 8-1-1 Function 1. When the appliance is plugged in, it defaults 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.
8-1-6 Alarm for Open Door 1. This feature sounds a buzzer when the freezer or refrigerator door is not closed within 1 minute after it is opened. 2. One minute after the door is opened, the buzzer sounds three times each for ½ second. These tones repeat every 30 seconds.
8-1-9 Electrical Parts Sequence of Operation Electrical parts such as compressor , defrosting heater, freezer fan, etc. are turned on in the following order to prevent noise and parts damage. Several parts are started at the same time at initial power on and are turned off together when TEST is completed.
8-1-10 Defect Diagnosis Function 1. Automatic diagnosis makes servicing the refrigerator easy. 2. When a defect occurs, the buttons will not operate; but the tones, such as ding, will sound. 3. When defect is repaired the defect code is removed and refrigerator returns to normal operation (RESET) 4.
8-1-11 TEST Mode 1. The test mode allows checking the PCB and the function of the product as well as finding out the defective part in case of an error. (See chart below) 2. The test mode is operated by pressing two buttons on the display panel. 3.
