Is the confirming
sound of valve operation heard after pressing
the Ice Maker Test switch?
Does
Main PCB IC71 #14 have about 0.7V
output?
Main PCB normal
-- Need to check the other parts
①
Check the wire between Ice Water Valve
↔
Main
PCB
②
Ice Water Valve itself has trouble or bad contact
of connector.
③
Check the connection hose
Does
Main PCB IC10 MICOM #30 have
HIGH(5V) output?
Is Main PCB RELAY
RY74 contact normal?

Preliminary Inspection
1. Water supplies directly to water valve. Please shut off 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.
3. To check the Ice Water Valve operation, shall press the Ice Maker Test switch and then check the operation.

2) IC71 #14 voltage
-.When Ice Water valve waiting (About 12V
±
0.7V)
-.When Ice Water valve waiting (About 0.7V
±
0.5V)
3) Check the voltage of Ice Water Valve operation (AC Voltage)
=> For checking Relay RY74 operation.

-.When Ice Water valve waiting (About AC 0V)
-.When Ice Water valve operating (About AC 115V
±
20%)
☞
Checking method of voltage
Based on PCB common Ground REG1 Heater Sink
1) Check the voltage of IC71 #5 (Same voltage as IC10 #30)
-.when Ice Water valve operating (About 5V±0.5V)
