1-18. Function of dispenser and water dispenser built-in 1) While any door of refrigerator is open, Ice type function can't be used. 2) There is 1 dispenser pad, this can be used to dispense cubed ice, crushed ice and water. 3) Press SELECT ICE TYPE button to illuminate your desired option to be dispensed. LED turn on to indicate option selected Control Type A 4) When pressing ICE TYPE pad in cubed ice or crushed ice option, Duct motor is activated by 1 second to open the duct door, it remains open mean while you keep pressed the pad, 5 seconds after pad release, duct motor becomes activated inverting motor polarity, in order to close duct door. Dispenser Pad has direct communication to the Main PCB, Main PCB read this signal as input to control Duct Motor and GEARED MOTOR. When Dispenser PAD is released, GEARED MOTOR will stop immediately, after 5 seconds Duct Motor will be activated to close Duct Door. 5) When pressing ICE TYPE pad in water option, water solenoid is activated allowing water dispensing. ICE TYPE pad has direct communication with the main PCB, Main PCB read this signal as input to control PILOT VALVE and WATER VALVE, When ICE TYPE pad is released, the PILOT VALVE and WATER VALVE is closed and water dispenser will stop. 6) While using any dispensing function and any door is opened, dispensing operation will be stopped immediately. 7) If ICE TYPE pad exceeds 3 minutes, GEARED MOTOR, CUBE SOLENOID or WATER SOLENOID will turn OFF automatically (this is a protection to avoid the overheating in the mentioned components), the duct motor will close Duct Door after 5 seconds after this interruption. 8) Last dispensing option (CUBED ICE, CRUSHED ICE or WATER) is saved in the internal memory of Main PCB and displayed by Display. Even after energy failure, Main PCB will display the last dispensing function used. - 29 -
