FZ-FAN Error
Display error during operation of
applicable fan motor : Feed back
signal line contact error, motor
wire separation, motor error
The voltage of MAIN PCB CN76-
“3”(Yellow)
↔
CN76-”1”(Gray): shall be
between 7V~12V
FF-FAN Error
The voltage of MAIN PCB CN76-
“4”(Orange)
↔
CN76-”1”(Gray): shall be
between 7V~12V
C-FAN Error
The voltage of MAIN PCB CN76- “5”(Sky-

CN76-”1”(Gray): shall be between
7V~12V
FZ-DEF Error
Separation of freezer 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 70
minutes.
After separating MAIN PCB CN70 wire from
PCB, resistance value between CN70

↔
CN70 Gray shall be 63(230)
ohm
±
7%.(Resistance value is varied by
input power) 0 ohm : heater short,
∞
ohm :
wire/bimetal open (Must power off)
