12-2 Icemaker functions
12-2-1 Start Position
12-2-2 Icemaking Mode
12-2-3 Ice Ejection Mode
1) When power is initially applied or reapplied after power is cut, it detects feeler arm of the TRAY after completion of MICOM
initialization. The detecting feeler arm moves up and down.
2) The feeler arm of icemaker tray is judged by output signal, high and low signal, of HALL SENSOR. Make the tray to
horizontal by rotating ice ejection motor in normal or reverse direction so that High/Low signal can be applied to MICOM
3) If there is no change in signals one minute after the geared motor starts to operate, it stops icemaker operation and check
the signal every hour. It resets initialization of icemaker when it becomes normal. Ice ejection conducts for 1 cycle.
a) Ice making control is carried out from the completion of water supply to the completion of ice making in the TRAY. Ice
making sensor detects the temperature of TRAY and completes ice making.(Ice making sensor is fixed below the TRAY.)
b) Ice making control starts after completion of water supply control or initial control.
Under the ice making control, the F room temperature should be operated with the NOTCH of “Normal/Strong”.
c) It is judged that ice making is completed when ice making sensor temperature reaches at -8
after 70 m 10
℃
minutes when water is supplied to the TRAY.
a) This is to eject ice from the TRAY after ice making is completed.
b) If HALL SENSOR signal is on within 3.6 seconds after ice ejection motor rotates in normal direction, it does not proceed ice
ejection but waits. If the ice bank is full, ice ejection motor rotates in normal direction in every hour to check the condition of
ice bank. If the ice bank is not full, the water supply control starts after completion of ice ejection control. If the ice bank is full,
ice ejection motor rotates in reverse direction and stops under ice making or waiting conditions.
c) If ice bank is not full, ice ejection starts. The TRAY tilts to the maximum and ice is separated from the TRAY and ice
checking lever raises.
d) Ice ejection motor stops for 1 second if HALL SENSOR signal changes from OFF (low) to ON (high) after 3.6 seconds when ice
ejection motor rotates 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.
e) If ice ejection motor or Hall IC is abnormal, ice ejection motor rotates in normal direction to exercise initial operation in
every hour. It resets the ice maker if ice ejection motor or Hall IC is normal.
f) The TRAY stops for 1 second at maximum tilted conditions.
g) The TRAY returns to horizontal conditions as ice ejection motor rotates in reverse direction.
h) When the TRAY becomes horizontal , the cycle starts to repeat.
Water Supply – Ice making – Ice ejection – TRAY returns to Horizontal.
