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          har-

vest. This can be from the (1) sensor not read-

ing the correct temp (2) or the sensor not 

mounted correctly (3). By programming the ice-

maker offset value to a lower number (4), the 

board not understanding the reading. 

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 1.5

Ԭ

  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

Ԭ

  for 5 minutes, it completes the harvest 

 (if the ice bin is not sensed as full).   

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.

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, when-

ever the ice is used, the freezer will again set to -14 degrees 

Fahrenheit. Selecting "Ice Off” will allow the freezer to be con-

trolled by the set temperature. If water is not hooked up, the 

freezer will always be at –14 unless “Ice Off” is selected.

 

DC FAN MOTORS

 

Brushless DC Fan motors are used to save energy. The fans operate at two speeds. Fan speed information is read by 

the Main PCB. If the fan speed exceeds 600 RPM or the speed is too slow, or stopped the fan drive circuit is disabled,  

After 10 seconds the circuit tries again with 3 seconds of DC voltage. If the fan continues this activity for 5 cycles, 10 

seconds off 3 seconds on, the fan drive circuit is disabled for 10 minutes. 

TO TEST THE FAN CIRCUIT VOLTAGE. 

Power off and back on to check the DC voltage to the motor, wait from 10 to 60 seconds for the fan voltage to kick in, 

and then check fan voltage, the average reading is 9 VDC.  If you get 3 seconds of voltage every 10 seconds for the 5 

fan power up cycles, then the Main PCB is good. 

NOTE: 

You may need to put unit in FORCED FREEZE mode to activate the fans/compressor. 

If the fan blade is blocked by ice, then defrost and check the motor again, after removing power from the unit. 

If the evaporator is ice blocked and thus blocking the air flow, the fan will over RPM and will be stopped. Remove ice 

and check the motor again. If everything is clear around the fan blade then the motor would be at fault. Continuous fan 

errors will be displayed on the front panel display. 

PLEASE NOTE: 

The door switches control the evaporator fan mo-

tors. Have them closed to test the motors. Delay time 10 – 60 seconds.
