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
freezer compartment defrost is heating
continuously for more than 80 minutes.
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.
When the Freezer Ice Maker error occurs
more than 3 times, the error will be
displayed.
When measuring the voltage between the Main
PCB CN30-"4" ↔ CN76-"1", it should read
between 4.5V~1.0V.
When measuring the voltage between the Main
PCB CN30-"5" ↔ CN76-"1", it should read
between 4.5V~1.0V.
The voltage of MAIN PCB CN30- "5"↔ N76-"1":
shall be between 4.5V~1.0V
When measuring the voltage between the Main
PCB CN30-"8" ↔ CN76-"1", it should read
between 4.5V~1.0V.
The voltage of MAIN PCB CN78- "8"↔ CN78-"
12": shall be between 4.5V~1.0V
The voltage of MAIN PCB CN78- "9"↔ CN76-"
1": shall be between 4.5V~1.0V
The Voltage of MAIN PCB CN90 #8<->#9: Shall
be between 4.5v ~ 1.0v
When measuring the voltage between the Main
PCB CN30-"3" ↔ CN76-"1", it should read
between 4.5V~1.0V.
The voltage of MAIN PCB CN90- "1"↔ CN90-"
7": shall be between 4.5V~1.0V
When measuring the voltage between the Main
PCB CN78-"10" ↔ CN78-"12", it should read
between 4.5V~1.0V.
The voltage of MAIN PCB CN76- "3"(Yellow) ↔
CN76-"1"(Gray): shall be between 7V~12V
The voltage of MAIN PCB CN76- "4"(Orange)
↔ CN76-"1"(Gray): shall be between 7V~12V
The voltage of MAIN PCB CN76- "5"(Sky-blue)
↔ CN76-"1"(Gray): shall be between 7V~12V
After separating MAIN PCB CN70 wire from
PCB, resistance value between CN70 Brown
↔ 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)
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)
After replacing the Ice Maker, check if it
operates normal.
