8028-0724/026.7 Troubleshooting - Light Emitting Diodes (LEDs)Light Emitting Diodes (LEDs) are provided on the PC Board to aid in troubleshooting electricaldifficulties. Referring to the wiring diagram included in this manual (also affixed to the electricalbox cover), the following information can be obtained from the LEDs.1. LED D3This light is on when the ice dispense switch is activated. If the chute is depressed and thelight does not turn on, check to see if the wire harness is connected or if the dispense switch isdefective.2. LED D4This light is used on units with lid interlock switches. This light should always be lit. If it is not,check the Lid Interlock Jumper (black wire with 4 pin white connector).3. LED D5This light is on when +5VDC is present at the circuit board. It should be lit whenever the unit isconnected to a power source. If the light is off, check to see if the internal circuit breaker onthe transformer has tripped. If it has tripped, it can be reset by depressing the switch on thetop of the transformer.4. LED D6This light is on when +32VDC is present at the circuit board. It should be lit whenever the unitis connected to a power source. If the light is off, check to see if the internal circuit breaker onthe transformer has tripped. If it has tripped, it can be reset by depressing the switch on thetop of the transformer.5. LED D7This light flashes when there is no ice between the sensors in the ice bin. If the bin is emptyand the light is not flashing, check all wiring harnesses.6. LED D8This light is on when the solenoid is activated. When the chute is depressed, this light shouldturn on. If it does not, check to see if the solenoid leads are connected to the PC board ordamaged, check continuity of solenoid. Replace if defective.7. LED D9This light is on when the motor is activated. When the chute is depressed, this light shouldturn on. If it does not, check to see if the motor harness is connected to the PC board ordamaged, check continuity of motor harness and motor. Replace if defective.
