4-2-11. If ICE Water is not supplied
Start
Is the confirming sound of
the valve operation heard when
Ice maker test switch pushed?
Does Main PCB MICOM
#12 have high (5V)output?
Does Main PCB IC73
#13 have about 0.7V
output?
Is the contact point of main
PCB RELAY RY79 normal?
MAIN PCB normal
-- Need to check the other parts
Check the wire between Ice
water valve MAIN PCB
Ice water valve itself has trouble
or bad contact of connector
Check the connection hose
Normal(Check Ice
water valve hose)

typical PCB Ground CN1#3(Black)
Checking method of voltage Based on
PCB typical Ground CN1#3(Black)
1) Check the voltage of IC73#4(same voltage
as IC02 #12)
- ICE Water valve operating (about 5V 0.5V)
Based on PCB typical Ground CN1#3(Black)
2) IC73 #13 voltage
- ICE Water valve operating (about 0.7V 0.5V)
3) Check the voltage of ICE Water Valve
operating(AC voltage)
=> For checking the Relay RY79 operating.
CN70#1(Red)
CN73#7(Purple)
- ICE Water valve waiting (about AC 0V)
- ICE Water valve operating (about AC 110V 20%)
