Diagnostic method
Separation of fresh food compartment
defrost heater housing part, contact
error, disconnection, short circuit or
temperature fuse error.
Display error : the defrosting does not
finish though fresh food compartment
defrost is heating continuously for more
than 80 minutes.
FF-DEF Error
After separating MAIN PCB CN70 wire from PCB,
resistance value between CN70 White ↔ CN70
Gray shall be 120(440) ohm± 7%.(Resistanc e
value is varied by input power)
0 ohm : heater short,
∞
ohm : wire/bimetal open
(Must power off)
Display error when open error is
detected by damper heater : separation
of Damper Heater housing part, contact
error, disconnection, short circuit
Flex Zone-Damper-
Heater 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.
Display error when open error is
detected by Heater : separation of Ice
Pipe Heater housing part, contact error,
disconnection, short circuit.
Ice Maker(FF)
Function Error
After changing the Ice Maker(R), plug the
refrigerator power code again, and check the
operation.
Display error when the Ice Maker(FZ) kit
operate moving ice over 3 times or it is
not leveled.
Ice Room-
FAN Error
The voltage of MAIN PCB CN76-”2”(Black) ↔
CN76-”1” (Gray): shall be between 7V~12V
Display “41 - E” in the panel with alarm :
MICOM MAIN ↔ PANEL communication error.
OP-Er is displayed when the Option is
not equivalent with the right value.
Panel ↔ Main
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.
