ICEMAKER AND DISPENSER OPERATION PRINCIPLE AND REPAIR METHOD
2-4. Ice Ejection Control Function
1. This function ejects the ice from the Icemaker cube mould after ice making is completed.
2. If Hall IC signal is on within 3.6 seconds after ice ejection motor rotates in normal direction, it does not proceed with ice
ejection. but waits. If the ice bin is full, ice ejection motor rotates in normal direction in every hour to check the condition of
ice bin. If the ice bin is not full, the water supply control starts after completion of ice ejection control. If the ice bin is full,
ice ejection motor rotates in reverse direction and stops ice making.
3. If ice bin is not full, ice ejection starts. The cube mould tilts to the maximum and ice is separated from the mould as ice
checking lever raises.
4. Ice ejection motor stops for 1 second if Hall IC signal changes from OFF (low) to ON (high) after 3.6 seconds when ice
ejection motor has rotated in normal direction. If there is no change in Hall IC signals within 1 minute after ice ejection
motor operates, ice ejection motor stops as ice ejection motor or Hall IC is out of order.
5. If ice ejection motor or Hall IC is abnormal, ice ejection motor rotates in normal direction to perform its reinitialization. It
resets the Icemaker if the ice ejection motor or Hall IC is normal.
6. The mould stops for 1 second at maximum tilted conditions.
7. The mould returns to a leveled position as ice ejection motor rotates in reverse direction.
8. When the mould is level, the cycle starts to repeat:
