How the Icemaker Works Please refer to the section “Operation of user manual” from page 13 to 16 . 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. Cooling System 6 7 8 NUMBER DESCRIPTION 1 Condenser 2 Multi‐connection pipe 3 Hot gas solenoid valve 4 Drier & Filte 5 Capillary tube 9 9.
9.2 10 19 39 Fan blade Discharge tube Wiring harness Controllerbox 39.1 Temperature sensor of the condenser 39.2 Temperature sensor of the evaporator 46 Evaporator (Ice Mold) 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.

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.
When green LED and yellow LED is lit, it means the unit is working in the cold preservation stage . 4. 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. Ice Size Adjustment Guide: FS‐55IM 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.

Troubleshooting ELECTRICAL SHOCK HAZARD Disconnect Electrical Power Before Beginning Removal of Parts Before Maintenance 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.
Proble m kinds Check part or point Plug Socket Power switch Fuse The Wiring machin connection e don't Voltage operate Ice full probe Ice full probe wiring Electric component Controller Water supply tap Water supply pipe Water System Water line Water inlet Water pump Possible Cause The icemaker is unplugged. Socket is damaged The icemaker power switch turns to OFF. The fuse is blown. Some wiring connection is incorrect or loosed The voltage of the power supply is low.
Drainage Drainage tray on top of tray on top the compressor is full of the compressor Problem kinds The compresso r doesn't start or start frequency Check part or point Wiring connects The start relay/ther mal protect The startup coil / running coil Condenser Fan The Electronic controller Refrigeran t The Capillary compresso tube r run Vent but no ice Hot gas valve The Electronic controller Drain off water by unscrewing lower drainage nut. Possible Cause Probable Correction loose.
2.Low production Problem kinds Cooling System Check part or point Refrigerant Condenser The ambient temperature Fan Hot gas valve Electronic controller Sensor Water distribution tube Water System Possible Cause Refrigerant leaks partially The condenser may be dirty. The ambient temperature is high or too low The fan is dirty or damaged Hot gas valve performance poor, leads to few ice is produced. The setting temperature of Electronic controller is low.
Cubes are too small Cubes are too big The ambient temperature Electronic controller Refrigerant Electronic controller The ice cubes shape deformity Adjust the temperature. ambient See the service manual "adjust the size of ice cubes" Recharge. See the service manual "adjust the size of ice cubes" Water quality Refrigerant leaks The setting temperature of Electronic controller is low. Temperature sensor of the evaporator damages The ambient temperature and water temperature is too low.

The ice full probe is broken or can not turn back normal position. The room temperature is out the stated range, the water pump stop Hot gas valve The hot gas valve is poor, The hot gas valve damage Ice mold of The ice mold is dirty, or polishing degree is the poor. evaporator Refrigerant Refrigerant leaks Ice machine Ice machine is not n tube Ice full probe doesn't The room spray temperature Harvesting ice is difficult Repair or replace the probe Make the temperature returns within the stated range.
Adjustment and Replacement Replace Controller, fuse and the sensor of temperature ELECTRICAL SHOCK HAZARD Disconnect Electrical Power Before Beginning Removal of Parts ¾ ¾ ¾ ¾ Remove the rear cover, front panel, Locate the Electronic controller, Pull out the sensors of temperature (one at the evaporator, another at the condenser). loosen the screws of rooting the Electronic controller, replace a new one.
