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.
