Temp Control &Operation Functions
Low Water Pressure → High Water Pressure
3) Ice Making Function
- It is until the water in the Ice Tray is judged as completely frozen after the completion of water supply
operation. And, it is judged by the sensor temperature (can be set to other values).
3-1) When it passes 58 minutes after water is supplied to the Ice Tray,the Ice Maker Sensor temperature will
be.
3-2) When the Ice Maker Sensor maintains lower than 5℉ (-15℃)for 5 minutes,it will be evaluated as the
completion of ice making.
3-3) Standby for One Cycle:After the completion of the initialization with the power on, it will standby for a cycle
(2 hours)and carry out the ice ejecting operation even if the temperature conditions of the Ice Maker
Sensor are satisfied.
4) Ice Ejection Function
- After the completion of the ice making operation, the operation of ice separation from the ice tray will be
carried out as follows.Ice ejection will be performed by checking the status and the time of the Horizontal S/W
(if available)and the Lever S/W. When it is sensed as No Water Supply,it will carry out ice ejection for twice in
case ice is not seperated from the ice tray.
※ Motor Rotating Directions
- CW Rotation:The motor rotates in clockwise direction.
- CCW Rotation:The motor rotates in counter clockwise direction.
4-1) 1) Detailed movements by step during Ejection.
-1st step : Ejection Temp Check
Check whether the temp sensor is below -15 ℃ and whether the Ejection Standby time after Water
Supply has passed. At this time,the Ejection Standby time will be reset when it goes into F-Defrost
during the standby and it will be recounted from the beginning after the completion of Defrost.Then, it
checks if 58(58~110)minutes has passed.If the Ice Maker Sensor temp gets 5 ℉(-15℃)or lower and
maintains it for 5 minutes,it will carry on the next step.
- 2nd step : Full Ice Bin Check
To check if the ice bin is full,it will check whether the Ice Full S/W is ON/OFF (Low/High).
If the Ice Full S/W is ON (Low),it means the ice bin is full and it will standby without ejection.And as the
Ice Full S/W signal is changed to OFF and it will carry out the ejection in 40 minutes.
- 3rd step : Ice Tray Rotation (clockwise)
The Eject Motor rotates clockwise for a certain time and turns over the ice tray.At this point, the Feeler
Arm will be raised up to prevent ice from contacting it The ice tray will rotate for up to one minute or until
the Leveling S/W is ON(Low)after 5 sec.from the beginning of the third step when referring to the
Leveling S/W.If F-Door is open,it will stop rotating and resume the operation when the door is
closed.During the pause, clockwise rotation will is not counted.
- 4th step : Ice Ejection (Standby for 2 sec.at the maximum twist point)
It is operation twisting the ice tray one more time with its reversed state to separate ice from the ice tray
completely.The ice tray will standby for 2 seconds at the maximum twist point.
