Test Procedure:

1.Disconnect the dispenser from the power source.

2.Open the dispenser door and remove the bottom door cover.

3.Disconnect the wires from the door interconnect wiring harness to the dispense switch to be tested.

4.Check for voltage across the black and red/white wires for the dispense switch to be teseted from the door interconnect wiring harness. Connect the dispenser to the power supply. The indication must be:

a)120 volts ac for two wire 120 volt models.

b)120 volts ac for three wire 120/208 volt or 120/ 240 volt models.

5.Disconnect the dispenser from the power source.

If voltage is present as described, proceed to #6.

If voltage is not present as described, refer to the wir- ing diagram and check the dispenser wiring harness.

6.With a voltmeter, check the voltage across the remaining two wires of the dispense switch being tested from the door interconnect wiring harness. Connect the dispenser to the power source. The indication must be +5 volts dc.

If voltage is present as described, proceed to #7.

If voltage is not present as described, refer to the wiring diagram and check the dispenser wiring har- ness.
