TROUBLESHOOTING

4-2-12. If ICE Water is not supplied

1.Please shut the water supplying prior to repair.

2.Power is applied to the one end of wires. Be careful when disassembling not to get an electric shock.

Typical PCB Ground REG1 Heater Sink

Checking method of voltage Based on

PCB typical Ground REG1 Heater Sink

1) Check the voltage of IC73#4(same voltage as IC01 #54)

- ICE Water valve operating (about 5V 0.5V)

Based on PCB typical Ground REG1 Heater Sink 2) IC73 #15 voltage

- ICE Water valve Waiting (about 13V 0.8V)

- ICE Water valve operating (about 0.7V 0.5V)

3) Check the voltage of Fridge Ice Water Valve operating(AC voltage)

=> For checking the Relay RY78 operating.

CN73 and CN74 combined and use same connector(13p) CN70#9(Red) 13P#7(Purple)

- ICE Water valve waiting (about AC 0V)

- ICE Water valve operating (about AC 115V 20%)

Start

Is the confirming sound of

the valve operation heard when Ice maker(R) test switch pushed?

Does Main PCB MICOM #54 have high (5V)output?

Does Main PCB IC73 #15 have about 0.7V output?

Is the contact point of main PCB RELAY RY78 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)
