TROUBLESHOOTING

4-2-4. If Ice Maker does not operate

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.

5.Be careful! The Ice Maker Heater can cause personal injury like burn.

6.Ice maker could operate not only genuine rotate but also reverse rotate, so it is not out of order that reverse rotate.
