Circuit Description
1. Electrify Status For The First Time
As the icemaker is properly installed. switch on the water tap, let the water trough full (reach on the
level), then turn the ICE/OFF/WASH switch to the ICE position on the front panel. The icemaker
will start working automatically
In this status, the time is fixed about 3 minutes. This function is also helpful to protect the
compressor avoiding restart within 3 minutes.
At this status, the Red, Green, Yellow LEDs are light together.
2. Ice-making Status
The compressor, motor fan and pump are powered on. The hot gas solenoid valve is powered off.
When this green 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.
The fan motor is also controlled by a condenser sensor. When the ambient temperature is too lower,
the motor fan stop working for good condensation to refrigerant.
3. Ice Harvest Status
The pump is powered off. The hot gas solenoid valve, compressor and motor fan is powered on.
The fan motor is also controlled by a condenser sensor. When the ambient temperature is too lower,
the motor fan stop working for good condensation to refrigerant.
The Yellow LED indicates the ice harvest status.
4. Ice Full StatusAnd Cold Preservation Stage
If the ice bin is fulfilled with ice or the full sensor is covered, the machine stops making ice and turn
to cold preservation stage automatically.
In this status, the compressor works regularly to keep the lower temperature for lower ice melting.
The rest of the electric components are powered off. The RED LED indicates the ice full
status and the GREEN AND YELLOW LED together indicates the cold preservation status .
Controller box:
Instructions for LEDs and buttons:
1. Red 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 in the ice storage bin. The unit will stop making ice. When ice cubes are taken out of the ice
storage bin making the ice-full probe free, the red LED will keep flashing 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.
