Operation
1. White LED: Ice full indicator light. When this LED is lit, the ice storage bin is full of ice or there is something
between the ice-full sensor and the evaporator. The unit will stop making ice. When ice cubes are taken out
of the ice storage bin making the ice-full probe free, the white LED will flash for 3 minutes. Then the unit will
restart and return to the ice making mode.
2. Green LED: Ice making indicator light. When this LED is lit, the unit is working in the ice making mode
controlled by a temperature probe on the evaporator. When the green LED is flashing, the unit is working in
the ice making mode controlled by a fixed timer.
3. Yellow LED: Ice harvest indicator light. When this LED is lit, the unit is working in the ice harvest mode
controlled by ice-full probe. When green LED and yellow LED is lit, it means the unit is working in the cold
preservation stage.
4. Red LED: power indicator light. The unit is on when the red LED is lit.
5. Mode button: Mainly for service. When this button is pressed, it can change from ice making mode to ice
harvest mode, or from ice harvest mode to ice making mode. You can see the change of the mode from the
status of the green and yellow LEDs.
NOTE: If during the ice size adjustment, the "BIN FULL", "ICE" and "HARVEST" LEDS blink all at once, this
indicates that the unit is in the default factory setting of the ice size adjustment.
CONTROL BOARD CHECKS
Timer Initiate
The timer initiate is a temperature sensor mounted on the liquid line to the evaporator. When the sensor
detects the correct low temperature, the freeze timer starts and the machine enters the timed portion of the
freeze cycle. When the freeze timer starts, the machine is in the timed portion of the freeze cycle. When
the machine enters harvest, the temperature rises, but the amount of time the machine is in harvest is
predetermined and is controlled by the Controller Board. Once the time has passed, the machine will enter the
harvest cycle. The timer is not adjustable, but the temperature at which the timer is initiated is adjustable.
ICE SIZE ADJUSTMENT
1. Press and hold the "Clean" button and the "Mode" button together for at least 3 seconds. The unit will
enter the Ice Size Adjustment mode. The GREEN LED will be blinking continuously during the ice size
adjustment.
2. While in the Ice Size Adjustment mode, press the "Clean" button or the "Mode" button for the desired ice
size.
Smaller ice setting: By pressing the "Clean" button, you can decrease the size of the ice cubes. The RED LED
will flash as you lower the ice size and will finally be blinking at the setting of smallest ice size.
Larger ice setting: By pressing the "Mode" button, you can increase the size of the ice cubes. The YELLOW
LED will flash as the larger size is set and will blink when the setting of largest ice size has been reached. After
10 seconds without any operation, the unit will automatically memorize the current setting and return to the
previous mode.
