Shattered Ice – Flex Tray
When all ice shatters, it's because of a bad
tray or ice cube temp that is too cold (lower
than -5 degrees). In some areas, there are
water issues that can also cause shattered
cubes. The temp in the freezer should not
have any effect on this issue, as long as it’s
below 1.5 degrees F, as a properly installed
sensor will not read the freezer temp, only the
water/ice temp.
Check the Ice tray for defects in the plastic.
Ice that is too cold will shatter during
harvest. This can be from the (1) sensor not
reading the correct temp (2) or the sensor not
mounted correctly (3). By programming the
icemaker offset value to a lower number (4),
the board not understanding the reading.
To check the sensor, you must check the tray
temp (not air temp) and compare it to the sen-
sor reading. The sensor should read 3.7 volts
at the main board connector when the cube
temperature is 1 degree. After the fill, the sen-
sor will read water temp 1.5 to 2.2 volts.
To clear offsets, put unit into Diagnostics
mode.
Please note, some shattering is normal for
a flex tray icemaker.
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 1.5Ԭ 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 1.5Ԭ 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.
