7-2-2 Icemaking 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 ice-making function will be completed in 4 hours.
NOTE :After icemaker power is ON, the icemaker heater will be on for test for 9 seconds.

2. Harvest mode:
(1) The heater is ON for 30 seconds, then the motor starts.
(2) After performing Step 1 (the heater is turned OFF), the ejector will be back in place wthin 18 minutes. (Hall sensor
sign = OV). Ice removal is then complete. Then the icemaker cycles to the fill mode. The water supply fails to start, it
is not functioning. Put the heater and motor in the off position. Restart every 2 hours. (Refer to figure1)
NOTE :If the motor malfunctions and starts before the detect lever rises, MICOM regards the Ice-Removing phase as
completed. Water then starts flowing. To prevent this, MICOM doesn't switch to water-supply mode, but restarts the ice-
removing mode. If this happens 3 times, the motor is malfunctioning and you should stop the loads (heater, motor). Then
restart the Ice-Removing mode every 2 hours. (See Step 2 above.)
