Is ice ejected?
What’s your selection
between crushed and cubed?
Is the cube ice ejected sufficiently?
Does ice in the ice tray exist ?
Do you see Ice Stop on the digital panel?
Is the Crushed Ice extracted
sufficiently?
Start
The close condition on operation
is subject to the freezer door.
1) Check the ice-ejector S/W.
2) Check the door S/W.
3) Check the ice moving motor.
4) Check the cut of wire in the Ice
moving Motor section.
Cancel Ice Stop, select
the Cubed/Crushed ice.
Normal operation
1) Check the water hose for folding or
fastening.
2) Check the ice-water-way and
solenoid value
3) Check the wires of ice-maker.
NO
Crushed ice
Cubed ice extracted
Normal operation
YES
NO
Does MICOM No. 25 turn 5V if
pressing Ice S/W?
Failure of Main PCB and exchange it.
YES
NO
Does the voltage
of IC3 No. 18 turn 0V even in the ice
S/W OFF?
Failure of Main PCB(IC3) and
exchange it.
YES
NO
Does the contact
shelf of RY77 relay turn 0Ω even in the
power OFF?
Failure of Main PCB – exchange.
(The contact terminal of RY77
relay short failure.)
YES
NO
Failure of Main PCB. –Exchange it.
NO
Failure of Main PCB(IC3) –
exchange it.
Main PCB is normal.
- - - Necessary to check other sections.
1) Check the wire between terminals of the AUGER motor
and main PCB.
2) Failure of cube solenoid itself, or bad contact of the
connector.
Main PCB is normal.
- - - Check other sections.
1) Check the wire between the
AUGER motor and main
PCB.
Measure both contact
terminals of RY77 after the
separation of CN70, CN71
connectors.
