7-2 ICE MAKER FUNCTIONS
7-2-1 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 ice making control.
(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. If EJECTOR is back in place within 18 minutes after the heater turns from ON to OFF, it is being initialized. If not, it is
not functioning. Repeat step B with heater and motor off.
7-2-2 Ice Making Mode
1. Icemaking refers to the freezing of supplied water in the ice trays. 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 icemaking function is completed when the sensor reaches -7°C, 60 to 240 minutes after starting.
4. If the temperature sensor is defective, the icemaking function will be completed in 4 hours.
NOTE : After icemaker power is ON, the icemaker heater will be on for test for 9 sec.
7-2-3 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) Harvest mode is completed if it reaches start position again while Heater & Motor are on at the same time.
A. ice bin is full : The EJECTOR stops (heater off).
B. ice bin is not full : The EJECTOR rotates twice to open for ice.
NOTE : If the EJECTOR does not rotate once within 5 minutes in status (2), 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.)
