Display error when open error is detected
by damper heater : separation of Damper
Heater housing part, contact error,
disconnection, short circuit.
The error occurs when there is a wire
connector slip-out of the Water Supply
Pipe Heater, a contact error or a
breakage in the wiring.
Display error when open error is detected
by Heater : separation of Ice Pipe Heater
housing part, contact error, disconnection,
short circuit.
Display error during operation of
applicable fan motor : Feed back signal
line contact error rnotor wire separation
motor error.
Display pc - Er in the panel with alarm :
MICOM MAIN ↔ PANEL communication
error.
The Error will be displayed when the Ice
Duct Heater is detected as being open
due to the followings.
- Ice Maker Duct Heater Connector Slip-
Out, Contact Defect or Wire-Breakage
The Error will be displayed when the Ice
Bucket Heater is detected as being open
due to the followings.
Ice Bucket Heater Connector Slip-Out,
Contact Defect or Wire-Breakage.
When the Compressor fails starting
When there is a IPM Fault error
When ther is abnormal crrunt detected at
the Compressor
When there is a Compressor restriction
error
When there is a low voltage error
When there is a over voltage error

After separating MAIN PCB CN77 wire from
PCB, resistance value between Black ↔ Brown
wire shall be 135 ohm± 7%.
0 ohm : heater short, ∞ Ohm : wire / bimetal
Open.
When measuring the resistance of the Main
PCB CN79 Yellow-Pink wires, it should be
within 102Ω ±7%.
0Ω : heater short, ∞Ω : Check for Wire Open
or Connector Slip-out
After changing the Ice Maker(R), plug the
refrigerator power code again, and check the
operation.
When measuring the voltage between the
Main PCB CN76-"5" ↔ CN76-"1", it should read
between 7.0V~12V.
Actually, If there is not a problem, it is desirable
to replace Main and Panel PCB With the
oscilloscope after a cable problem confirming.
The resistance between CN79 ORG and CN51
BRN on the Main PCB shall be within 135Ω ±
7%. And, when the resistance reads 0Ω or ∞
Ω, check the followings.
0Ω : Heater Short
∞Ω : Wire-Breakage or Wire Slip-Out
The resistance between CN79 ORG and BRN
on the Main PCB shall be within 135Ω ±7%.
And, when the resistance reads 0Ω or ∞Ω,
check the followings.
0Ω : Heater Short
∞Ω : Wire-Breakage or Wire Slip-Out
Check if there is a short between compressor
terminals. Check IPM Voltage [Under 13.5V]
Check if there is a short between IPM Pins
[#1~33]
Check the Compressor and the Cycle
Check the Compressor connections
Check the voltage of Resistance of R308
[0.09Ohm] Check the Compressor and the
Cycle
Check the voltage of Resistance of R308
[Short/Open] Check the voltage of both of
C103 terminals [Unstable Voltage] Check the
Compressor and the Cycle
Check the voltage of Resistance of R513 [Short/
Open]
Check the voltage of Resistance of R501, R505,
R509 [Short/Open]
