LED DESCRIPTION
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.
D4 This light is used on units with lid interlock switches. On the 4500 series ice-beverage dispenser, this light should
always be lit. If it is not, check the Lid Interlock Jumper (black wire with 4 pin white connector).
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.
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.
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.
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.
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.
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.
