FLEX TRAY Ice Makers
When the initial power is applied, the ice tray will stand by for 2
hours. After the 2-hour standby time, the Ice Maker Sensor will check
the temperature , when it is lower than 1.5? for more than 5 minutes,
it will do a harvest, with or without ice in the tray, then fill with water.
58 minutes after water is supplied to the Ice Tray, the Ice Maker
Sensor temperature will be checked. When the Ice Maker Sensor
maintains lower than 1.5? for 5 minutes, it completes the harvest
(if the ice bin is not sensed as full).
Thermistor senses temperature to determine water fill on newer units
Filling the tray
After the water fill is completed, the ice maker sensor will evaluate the
water volume one and a half minutes later. When it detects no or low
water level, it will add more water. First supply time will be 1.5 sec,
next one will be 1 sec and the last will be 2 sec.
