4-2 Introduction of E-Linear Compressor
E-Linear compressor 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.
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.
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

4-1-1 Role
4-1 COMPRESSOR
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.
4-1-2 Note for Usage
(1) Be careful not to allow over-voltage and 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.
4-1-3 REMOVE THE COVER PTC
(1) Remove the Cover Back M/C
(2) Loosen two screws on comp base
(3) Use a L-shaped flap tooll to pry off the cover
(4) Assembly in reverse order of disassembly

4-2-4 Compressor problems diagnosis
When there is a problem or failure with the `operation,
you are kindly recommended to check it as follows ;
Measure the resistance between poles of the hermetic
terminal (as shown picture) with a multi-tester.
(measurement several minutes after power off)
Normal resistance range (measured at ambient
temperature 23 )
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.
1) Check to normality by measurement of resistance
According to ambient temperature or operation situation,
the values could show a little deviation.
4-2-3 Compressor 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).
P : Power Line
C : Common Line Multi-tester

- 20 -
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.
Warning
1. Please be cautious of electric shock and short (it is
estimated after turning on initial power).
2. If the voltage is estimated less than 80V, it is diagnosed
as bad.
2) Check to normality by measurement of Voltage
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.

3) Check problems by LED On & Off Count _ (Sub PCB)
-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-Fan and 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.

10-4 How to check the Fan-Error
(1) EBR673480
After sending a signal to the fan, the MICOM checks the BLDC fan
motor s lock status. If there is no feedback signal from the BLDC fan,
the fan motor stops for 10 seconds and then is powered again for 15
seconds. To determine that there is a fan motor malfunction,
this process is repeated 3 times. If the fan motor is determined to be
defective, the error code will be shown in the display for 30 minutes.
At this point, the process will be repeated until the fan motor operates
normally. If normal operation is achieved, the error display is erased and
the MICOM is reset automatically.

To reduce noise level, the piston stroke is slowly increased to full power during start up.
There are 6 protection logics designed to protect the linear compressor system. When a failure is detected,
the compressor will shut and will try to restart after a set period of time for each type of failure. The LED
located on the inverter drive PCB will flash the appropriate code to indicate the detected failure. This code will
continue to flash until the unit is disconnected from the power source.
Inverter Error Codes
Step 1) Start up - Half stroke interval for first 1 second.
Step 2) Ramp up - Stroke increases every 0.8sec until
maximum stroke length is reached
(about 1 min)
Step 3) CVCF interval - 180V / 60Hz

Bridge Diodes converts 115V AC (Alternating current) to 115V DC (Direct current)
The Voltage Multiplying circuit then increases the 115V DC to 230V DC.
Then the IPM (Intelligent Power Module) converts the 230V DC to 230V AC.
The converted AC power can be regulated to any required voltage and frequency.
Measure the voltage at locations on the connector (as shown picture) with a multi-tester.
There is a PCB located in the PCB case next to the
compressor. That is the driver PCB, the linear
compressor.

13-2-1 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 Ice Making function is completed when the sensor reaches 19°F (-7°C), 55 minutes after starting.
NOTE : After Icemaker Power is ON, the Icemaker heater will be on for test for 6 sec.
13-2-2 Harvest Mode
1. Harvest (Ice removing) refers to the operation of dropping ices into the ice bin from the tray when icemaking has
completed.
2. Harvest mode:
(1)The Heater is ON for 30 seconds, then the motor starts.
(2)The feeler arm senses the quantity of ice in the ice storage bin while rotating with the EJECTOR.
A. Ice storage bin is full : The EJECTOR stops (heater off).
B. Ice storage bin is not full : The EJECTOR rotates twice to open for ice.
If the EJECTOR does not rotate once within 5 minutes in B mode, separate heater control mode starts operating to
prevent the EJECTOR from being constrained. (It is recommended that the user open for ice to return to normal mode.)
