IMPORTANT SAFETY NOTICE – “For Technicians Only” This service data sheet is

intended for use by persons having electrical, electronic, and mechanical experience
and knowledge at a level generally considered acceptable in the appliance repair trade.
Any attempt to repair a major appliance may result in personal injury and property
damage. The manufacturer or seller cannot be responsible, nor assume any liability for
injury or damage of any kind arising from the use of this data sheet.

Self Diagnosis: Press both buttons (Power
Freeze—Power Cool) simultaneously (No
sound when both buttons are pressed at the
same time) ’til the display quits blinking and
beeps, 8-12 seconds, then release and read
Fault Codes.
This will also cancel the Fault Mode created
by self-diagnosis at power up.

Forced Mode: Press both buttons (Power
Freeze – Fridge) simultaneously (No sound
when both buttons are pressed at the same
time) ‘til it beeps and goes blank, 8-12 seconds

Wait 5 seconds between button pushes

FLEX TRAY Ice Makers

2

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.

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 sen­sor reading. The sensor should read 3.7 volts
at the main board connector when the cube
temperature is 1 degree. After the fill, the sen­sor 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.

FREEZER TEMPERATURE CONTROL BY THE ICE MAKER

Interior Temperature of the freezer will be set to -14 degrees Fahrenheit until the ice bucket is full. When the ice
bucket is full, the freezer will maintain original set temperature. Also, whenever the ice is used, the freezer will
again set to -14 degrees Fahrenheit. Selecting "Ice Off” will allow the freezer to be controlled by the set tem­perature. If water is not hooked up, the freezer will always be at –14 unless “Ice Off” is selected.

DEFROST

This model series uses a Defrost Heater in the Fridge and the Freezer compartment that is part of the Evaporator Coil.

NOTE: Evaporator Covers May Break If Removed While Frozen To Coil. They must be replaced if there is any damage,
as this will cause “ice” to form at top or bottom of the evaporator coil or in the drains.
