TROUBLESHOOTING
1. Water is automatically supplied to the Ice Maker depending on temperature & time condition and Ice
Maker Dispenses cubed or crushed ice.
2. Power is applied to the one end of wires. Be careful when disassembling and shall refer to its
exploded diagram in any case.
3. Ice Maker operation shall be checked after pressing the Ice Maker testing switch.
(Freezer Ice Maker) It is not possible to check when the power is disengaged.
4. We recommend that TWO PEOPLE check the PCB and Ice Maker because they are located at front
and rear side each.
4-2-5. If ICE MAKER(F) does not operate
Is the checking location by
self sensing when initial Power ON?
Does ice
Maker Rotate when pressing the Ice Maker
testing switch?
Is the input voltage of IC01
MICOM #39 normal?
Is the water
supplied in 6 minutes(After sensing ice
bucket fully?
Is the ice Maker Sensor
unit normal?
