Troubleshooting - Light Emitting Diodes (LEDs)
Light Emitting Diodes (LEDs) are provided on the PC Board to aid in troubleshooting electrical
difficulties. Referring to the wiring diagram included in this manual (also affixed to the electrical
box cover), the following information can be obtained from the LEDs.
1. LED D3
This light is on when the ice dispense switch is activated. If the chute is depressed and the
light does not turn on, check to see if the wire harness is connected or if the dispense switch is
defective.
2. LED D4
This 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 D5
This light is on when +5VDC is present at the circuit board. It should be lit whenever the unit is
connected to a power source. If the light is off, check to see if the internal circuit breaker on
the transformer has tripped. If it has tripped, it can be reset by depressing the switch on the
top of the transformer.
4. LED D6
This light is on when +32VDC is present at the circuit board. It should be lit whenever the unit
is connected to a power source. If the light is off, check to see if the internal circuit breaker on
the transformer has tripped. If it has tripped, it can be reset by depressing the switch on the
top of the transformer.
5. LED D7
This light flashes when there is no ice between the sensors in the ice bin. If the bin is empty
and the light is not flashing, check all wiring harnesses.
6. LED D8
This light is on when the solenoid is activated. When the chute is depressed, this light should
turn on. If it does not, check to see if the solenoid leads are connected to the PC board or
damaged, check continuity of solenoid. Replace if defective.
7. LED D9
This light is on when the motor is activated. When the chute is depressed, this light should
turn on. If it does not, check to see if the motor harness is connected to the PC board or
damaged, check continuity of motor harness and motor. Replace if defective.
