or
Pantry-Damper-
Heater Error
Display error when open error is detected
by damper heater : separation of Damper
Heater housing part, contact error,
disconnection, short circuit.
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.
FZ-Ice Pipe Heater
Error
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.
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
Ice Maker(FF) Function
Error
Display error when open error is detected
by Heater : separation of Ice Pipe Heater
housing part, contact error, disconnection,
short circuit.
After changing the Ice Maker(R), plug the
refrigerator power code again, and check the
operation.
Ice Room-FAN Error
Display error during operation of
applicable fan motor : Feed back signal
line contact error rnotor wire separation
motor error.
When measuring the voltage between the
Main PCB CN76-"2" ↔ CN76-"1", it should read
between 7.0V~12V.
Panel ↔ Main
Communication Error
Display pc - Er in the panel with alarm :
MICOM MAIN ↔ PANEL communication
error. Actually, If there is not a problem, it is desirable
to replace Main and Panel PCB With the
oscilloscope after a cable problem confirming.
Main - Inverter
Communication Error
Display 44Er in the panel :
Inverter MICOM ↔ Main MICOM
communication error. Actually, If there is not a problem, it is desirable
to replace Main and Inverter PCB With the
oscilloscope after a cable problem confirming.
I/O Expander
Communication Error
Display 46Er in the panel :
I/O Expander↔ Main MICOM
communication error.
It is desirable to replace Main PCB.
FF Ice Pipe Heater
Error
The Error will be displayed when the
FF Ice Pipe Heater is detected as being
open due to the followings.
- Ice Maker Pipe Heater Connector Slip-
Out, Contact Defect or Wire-Breakage
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
FF Ice Room Heater
Error
The Error will be displayed when the Ice
Ice Room Heater is detected as being
open due to the followings.
Ice Room Heater Connector Slip-Out,
Contact Defect or Wire-Breakage.
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
Comp starting Failure
Error
When the Compressor fails starting
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
IPM Fanlt Error When there is a IPM Fault error
Comp Abnormal
current Detection
Error
When ther is abnormal crrunt detected at
the Compressor
Check the Compressor connections Check the
voltage of Resistance of R308
[0.09Ohm] Check the Compressor and the
Cycle
Motor Locked Over
RPM Error When there is a Compressor restriction
error
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
Comp under voltage
Error
When there is a low voltage error
Check the voltage of Resistance of R513 [Short/
Open]
Comp over voltage
Eroor
When there is a over voltage error
Check the voltage of Resistance of R501, R505,
R509 [Short/Open]
