Flex Zone-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.
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 when the Ice
Maker(FZ) kit operate moving ice
over 3 times or it is not leveled. The voltage of MAIN PCB CN76-”2”(Black)
↔
CN76-”1” (Gray): shall be between
7V~12V

right value.
Actually, If there is not a problem, it is
desirable to replace Main and Panel PCB
With the oscilloscope after a cable
problem confirming.
Ice Duck-
Heater Error
Dispay error when open error is
detected by Heater: separation of
Water Tank Heater housing,
contact error, disconnection, short
circuit
After separating MAIN PCB CN51 and
CN79 wires from PCB, the resistant value
between CN79 Yellow
↔
CN51 Brown wire
shall be 60 ohm
±
7%.
0 ohm : heater short,
∞
Ohm : wire /
bimetal Open.
