MOTOR COVER 2) Pull and separate the FAN ASSEMBLY and MOTOR turning counterclockwise based on the MOTOR SHAFT. FAN ASSEMBLY MOTOR The assembly is in the reverse order of the disassembly and take special care for the following details. Be careful not to bend the tube during assembly. Press the WATER DISPENSER button until water pours out and check for leakage in the CONNECTOR TUBE (It differs by the water pressure but usually takes about 2 minutes until water pours out.). 4-1COMPRESSOR 4-1-1Role The compressor intakes low temperature and low pressure gas from the evaporator of the refrigerator and compresses this gas to high-temperatureand high-pressuregas. It then delivers the gas to the condenser.
4-1-2Note for Usage (1) Be careful not to allow over-voltageand over-current. (2) Do not drop or handle carelessly. (3) Keep away from any liquid. If liquid such as oil or water enters the Cover PTC Compressor may fail due to breakdown of their insulating capabilities. (4) Always use the Parts designed for the compressor and make sure it is properly attached to the compressor. Parts may appear physically identical but could have different electrical ratings. Replace parts by part number and model number.
Use only approved substitute parts. 4-1-3REMOVE THE COVER PTC (1) Remove the Cover Back M/C (2) Loosen two screws on comp base (3) Use a L-shapedflap tooll to pry off the cover (4) Assembly in reverse order of disassembly. 4-2Introduction of E-LinearCompressor E-Linearcompressor is run by mechanical part design through automatically varying the cooling power. The main parts consist of compressor and Sub PCB which controls the compressor. PCB authorizes constant voltage and constant frequency to the compressor and protects it. 4-2-1Control of Compressor Block Diagram PWM Linear Compressor Controller Signal Inverter Frequ Comp -ency DC link Vcap Voltage Voltage Main Counter elec- Micom tromotive force Calculate counter electromotive force Control Block Diagram of Compressor 4-2-2Compressor operating pattern Drive half stroke after turning on initial power for 30 seconds. Then, slowly increase stroke and reach target input.
Once reaching the target input, input naturally changes according to refrigerator load without any special control. Input Interval 1) Half stroke interval - after initial running, stay at the initial value for 30 seconds Interval 2) Running interval - Increase at every 0.8 till it reaches the target input; it takes about 3 Minutes and 45 seconds.
Interval 3) CVCF interval - Run by target voltage and main operating frequency and the input naturally changes according to refrigerator load. 4-2-3Compressor protection logic Since linear Comp conducts linear reciprocating motion, we have protection logic for compressor, motor and PCB as the below. Stroke Trip During the operation, if stroke is above the target value, decrease the target volt by 3V. Current Trip Current trip is set in order to protect compressor mechanical part and drive from the overcurrent that might arise during the operation. Check the current for every 416.7us and if the Trip exceeds 1.86Arms more than three times at Comp ON, forcibly stop and restart six minutes later.
Lock Piston Trip If stroke is under 5mm even if the current is more than 14Arms, Take it as ‘piston lock’ and restart after 2’30” of Comp OFF. Check the current and stroke for every 416.7us and if the condition fits more than three times at Comp ON, the Trip occurs. IPM fault Trip It occurs if FO signal received from IPM is LOW. For every 416.7us, check whether FO signal is LOW. The trip occurs if it is found three times during the five periods(83ms). 4-2-4Compressor problems diagnosis When there is a problem or failure with the `operation, you are kindly recommended to check it as follows; 1) Check to normality by measurement of resistance Measure the resistance between poles of the hermetic terminal (as shown picture) with a multi-tester.(measurement several minutes after power off) P: Power Line C: Common Line Multi-tester Case 1-1 If the measured values lie in the normal resistance range as in the table below, Compressor is normal.
Case 1-2 If the measured values are above several M or a infinity, Wire is disconnected in the shell. Case 1-3 If the measured values are excessively of small number, There is short somewhere in the shell. Normal resistance range (measured at ambient temperature 23 ) Resistance FC75LANE 68 According to ambient temperature or operation situation, the values could show a little deviation. 2) Check to normality by measurement of Voltage Measure the resistance between pin of the connector (as shown picture) with a multi-tester. Standard for normality - In order to decide whether compressor operating is normal or not, check the output transfer during the refrigerator operation. After input the initial power and compressor operates, wait for 10 minutes to estimate.
Compressor operation may be diagnosed as normal if the voltage falls between 145V and 180V. Please be cautious of electric shock and short (it is estimated after turning on initial power). If the voltage is estimated less than 80V, it is diagnosed as bad. 3) Check problems by LED On & Off Count (Sub PCB) If compressor protection logic is running, LED Lamp’s blinking frequency of sub PCB, which takes in charge of control, can help estimate the protection logic’s symptoms and the cause of its problems. Trip name Led Times Comp Off Time Stroke Trip 2 1min Current Trip 6 6min Lock Piston Trip 5 2min 30sec IPM fault trip 7 20sec - Current Trip PCB defects or Cycle clogging maybe the causes.
After estimating winding resistance, estimate compressor operation voltage to check if there is any problem and take actions to repair cycle at replacement of compressor. Stroke Trip can occur when the surrounding temperature is high, C-Fan, F-Fanand so on are constrained, or when cycle problems, such as moisture blocking or compressor defect, are related. Lock Piston Trip Since compressor itself can be a potential cause of a defect, estimate the compressor resistance value according to #1’s compressor winding value estimation method and estimate the #2’s compressor operation voltage to decide whether it is defective or not (Before replacement of compressor, replace PCB and conduct the replacement of compressor during compressor replacement) - IPM fault Trip Replace sub PCB since there is high chance that it is caused by sub PCB’s part defect.
