Diagnostic method
When checking the voltage of MAIN PCB
CN90 #3 ↔ #4 : Shall be between
4.5V~1.0V.
When checking the voltage of MAIN PCB
CN30 #3 ↔ #8 : Shall be between
4.5V~1.0V.
When checking the voltage of MAIN PCB
CN30 #4 ↔ #8 : Shall be between
4.5V~1.0V.
Voltage of MAIN PCB CN76
Yellow ↔ Gray : Shall be between 7V~12V.
After replacing ice maker, check the
operation by turning the appliance ON again.
After separating MAIN PCB CN72 wire
from PCB, the checked resistance value of
CN70 White ↔ Orange shall be
103/397ohm ± 10%
(Resistance value is varied by input power)
↔ Model without Ice maker (120ohm ± 10%)
Check 0 Ohm for heater short, &æOhm for
wire / bimetal Open.
When checking the voltage of MAIN PCB
CN31 #1 ↔ #3 : Shall be between
4.5V~1.0V.
When checking the voltage of MAIN PCB
CN30 #5 ↔ #8 : Shall be between
4.5V~1.0V.
When checking the voltage of MAIN PCB
CN30 #6 ↔ #8 : Shall be between
4.5V~1.0V.
Voltage of MAIN PCB CN76 Pink ↔ Gray :
Shall be between 7V~12V.
Voltage of MAIN PCB CN76 Blue ↔ Gray :
Shall be between 7V~12V.
After separating MAIN PCB CN72 wire
from PCB, the checked resistance value of
CN70 Brown ↔ Orange shall be
66/240 ohm ± 10%.
(Resistance value is varied by input power)
Check 0 Ohm for heater short, &æOhm for
wire / bimetal Open.
