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 0

Ω

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.
