2. ICEMAKER FUNCTIONS
2-1. Start Position
1. After POWER OFF or power outage, check the EJECTOR's position with MICOM initialization to restart.
2. How to check if it is in place:
- Check HIGH/LOW signals from HALL SENSOR in MICOM PIN.
3. Control Method to check if it is in place:
(1) EJECTOR is in place,
- It is an initialized control, so the mode can be changed to icemaking mode.
(2) EJECTOR isn't in place:
A. If EJECTOR is back in place within 2 minutes with the motor on, it is being initialized. If not, go to Step B.
B. Control the heater using the temperature sensor until the EJECTOR reaches the correct location.
2-2. Icemaking Mode
1. Icemaking refers to the freezing of supplied water in the ice tray. Complete freezing is assured by measuring the
temperature of the Tray with Icemaking SENSOR.
2. Icemaking starts after completion of the water fill operation.
3. The Ice Making function is completed when the sensor reaches 19°F (-7°C), 55 minutes after starting.
NOTE : After Icemaker Power is ON, the Icemaker heater will be on for test for 6 sec.
2-3. Harvest Mode
1. Harvest (Ice removing) refers to the operation of dropping ices into the ice bin from the tray when icemaking has
completed.
2. Harvest mode:
(1) The Heater is ON for 30 seconds, then the motor starts.
(2) The feeler arm senses the quantity of ice in the ice bin while rotating with the EJECTOR.
A. ice bin is full : The EJECTOR stops (heater off).
B. ice bin is not full : The EJECTOR rotates twice to open for ice.
If the EJECTOR does not rotate once within 5 minutes in B mode, separate heater control mode starts operating to
prevent the EJECTOR from being constrained. (It is recommended that the user open for ice to return to normal mode.)
2-4. Fill/Park Position
1. Once a normal harvest mode has been completed, the water solenoid will be activated.
2. The amount of water is adjusted by pressing the Fill Key repeatedly. This changes the time allowed for fill as illustrated in
the table below.
