IMPORTANT: The service manual is based on the user manual. Before
servicing, please read user manual and service manual carefully. The service
operation should be implemented by qualified technician.

How the Icemaker Works
Please refer to the section “Operation of user manual” from page 12 to 14 . It describes clear
how the icemaker makes ice and uses the water.
There are 3 systems including Cooling System, Water System and Wiring Connection and
Controller.

17 1854204603 Control box
During the ice-making stage, the hot gas solenoid valve is closed. The hot refrigerant gas is
pumped out off compressor to condenser. The hot gas is cooled by fan forced air to warm liquid
refrigerant after passing through the condenser. The drier & filter reduces the possible dirty and
humidity in the refrigerant. The evaporator is cooled by the refrigerant. So ice can formed on
the evaporator during water is sprayed to the evaporator. Low pressure refrigerant gas may go
back compressor from the evaporator.
During the ice harvest stage, the solenoid valve is open. The hot refrigerant gas is pumped out
off compressor to evaporator through hot gas valve. As the hot gas is not cooled by the
condenser, the refrigerant makes the evaporator (ice mold) warm. So some ice touching the
evaporator is thawed. All of ice can slide down to the ice storage bin.
Water System
When the water supply pipe is connected with the main water supply, water will fill the water
trough through the floater valve till enough water inside water trough makes floater valve close.
During ice-making stage, water is pumped from the water trough to the water distribution tube.
The distributed water flow the surface of evaporator. Most parts of water go back water trough.
Some water is frozen on the evaporator step by step. The floater valve will open and fresh water
is recruited at any moment.

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 Power switch to the ON position on the 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 White, Green, Yellow and Red 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.

3
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.
5. Cleaning Status
Turn the machine CLEAN SWITCH at the CLEAN in 3 minutes after the POWER SWITCH is
turned on, the machine turn to Cleaning Status. At this status, the pump is powered on. Compressor,
motor fan and the hot gas solenoid valve are powered off. The GREEN and YOLLOW LEDs are
flashing together. To stop the cleaning mode, turn the machine “OFF” at the Power switch or it
will turned off automatically after 30 minutes.
NOTE: In order to start the Clean Status the power switch must be on. The CLEAN switch must
be turned in 3 before the COMPRESSOR starts. To clean, it is no use turning the CLEAN switch
when machine is in ice-making status or ice-harvest status.
Controller box:
Instructions for LEDs and buttons:
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 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.
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 power 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 judge the mode from the status of
the green and yellow LEDs.
6. Ice size adjust: Turn the screw clockwise, and the size of individual ice cubes will be larger in
the next cycle; the cycle time will be longer. Turn the screw counter clockwise, and the ice size
will be smaller in the next cycle.
NOTE: It is not a good idea to adjust the ice size often or for no good reason, because the
controller may damaged.
IMPORTANT
*1. Avoid water to the controller box.
*2. To start the Clean Status the power switch must be on. The CLEAN switch must be turned in
3 minutes before the COMPRESSOR starts.
*3. When turn the machine “ON” at the Power switch, the compressor, motor fan and pump will
be delayed 3 minutes to power on to protect compressor. At this moment, the Red, Green, Yellow
and White LEDs are light together.
MAJOR FUNCTIONS OF CONTROLLER
1. Completely automatic operating procedure.

2. When the ice storage bin is full of ice cubes，the machine stops making ice and
turn into cold preservation stage automatically and starts making ice again after
the ice cubes are removed.
3. The different colors of the LED display indicate various work modes.
4. The fan motor responds to the ambient temperature. If it is cold, the motor will
stop working to keep the cooling system in good working condition.
5. The thickness of ice cubes is adjustable.
6. A sensitive probe and accurate timer enhance the performance of the ice maker.
7. Built-in compressor protection system.

Before Maintenance
ELECTRICAL SHOCK HAZARD
Disconnect Electrical Power Before
Beginning Removal of Parts
1. Check out the user if the user uses a 115 VAC, 60Hz. only 15ampere electrical supply,
and have properly grounded, ensure the maintainer against electrical shock.
2. Check out the leads loose? Turn off? Short circuit? If have such problems, foreclose in turn.
Basic Checking
The icemaker has some trouble, through the appearance phenomena judges. So the
service technician must check it thoroughly, then maintain.
Hearing
¾Hearing the user 's depiction about the icemaker at using process and the phenomena.
Try to understand what is the defect and how did the user operate the icemaker
before calling for service.
¾If the running sound is normal?
Looking
¾Check the pipe of cooling system, especially the welding point. If there is some oil,
the gas is leak out so that no ice making or less ice produced.
¾If the cycle of the ice making and harvest is normal?
¾Check the water system, especially the connection. If there is some water leakage.
¾Check if the water filter needs to be replaced.
¾Check if the icemaker installed according to the user manual.
¾Check if the icemaker needs to be cleaned.
Touching
¾Touch the hot gas pipe (with the evaporation weld), feeling the temperature. At the
ice making stage, feeling cool.At the ice harvest stage, feeling hot.
¾Touch the capillary tube (the drier nearby), feeling tepefaction.
