for ice off?

 

 

Check point of contact of ice drawing S/W

 

 

 

 

 

 

 

 

 

 

Check point of contact of door S/W.

 

 

 

 

YES

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Check point of contact of ice transfer motor.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Release the icing stop Select ice

 

 

Check point of contact for wiring of the ice transfer motor

 

 

 

 

 

 

 

 

 

ice cubed/crushed

 

 

crushed ice

 

 

 

 

 

 

 

 

 

What is the ice status on the panel Display?

 

 

 

 

 

 

 

1) Check water supply hose. - bent or turned off.

 

cubed ice

 

 

2) Check water supply parts for icing solenoid check

 

 

 

 

 

 

 

3) Check icemaker wire.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Do ice cubed come out when

YES

Does crushed ice come

 

YES

 

 

out when pulling ice out?

 

 

 

 

 

drawing ice?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

No

Does MAIN MICOM No. 14

 

NO

 

 

 

change to 0V when pressing ice s/w?

 

 

 

 

 

 

 

 

 

YES

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

- Check ice s/w has failure itself.

 

 

 

 

 

 

 

 

 

 

- Check connected.

 

 

 

 

 

- Main PCB failure: Replace it.

 

 

 

 

 

 

 

 

 

 

 

NO

Does MAIN MICOM No. 17 change to

0V when pressing and holding ice s/w?

 

 

 

 

 

 

 

 

 

Measure both terminals of RY7C

 

 

YES

 

 

 

 

contact point after disconnecting CN72

 

 

 

 

Main PCB failure: Replace it

and CN73 connectors.

 

 

 

 

(IC74 failure).

 

 

 

 

 

 

 

 

 

 

 

Is the contact terminal of RY7E

 

NO

 

 

 

relay 0 when pressing ice s/w?

 

 

 

 

 

 

YES

 

 

 

 

 

 

 

 

 

 

 

 

 

 

- RY7E relay failure

 

 

 

 

 

- Main PCB failure: Replace it.

 

 

 

 

 

 

 

 

 

 

 

 

 

Normal Main PCB

- Need to check other sections.

Check the wire between AUGER MOTOR and MAIN PCB. Failure of CUBE MOTOR itself or connecting connector contact failure.

Does Main MICOM No. 14 change

No

 

to 0V when pressing ice s/w?

 

 

 

 

YES

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Main PCB failure: Replace it.

 

 

 

Did cube motor move to ice crushed

No

location? (Load MICOM No. 28 is 5V?)

 

 

 

 

 

 

 

 

 

- When LOAD MICOM No. 28 is 0V continuously,

 

YES

 

CUBE MOTOR and IC74 should be checked.

 

 

 

- Check CUBE MOTOR S/W.

 

 

 

 

 

- Check CN73,CN40 WIRE.

 

 

 

Does IC74 No. 17 change to 0V

No

when pressing and holding ice s/w?

 

 

 

 

 

 

 

 

 

Main PCB failure: Replace it (IC74 Failure).

 

YES

 

Measure the both terminals of RY7E contact point

 

 

 

 

 

 

 

 

after disconnecting CN72 and CN73 connectors.

 

 

 

Is RY7E RELAY contact terminal

No

0even when power off?

 

 

 

 

 

 

 

 

 

 

 

YES

 

Main PCB failure: Replace it.

 

 

(RY7E Relay contact terminal short failure)

 

 

 

 

 

Normal Main PCB

- Need to check the other sections.

Check the wire between AUGER MOTOR and MAIN PCB. Failure of CUBE MOTOR itself connector contact failure.
