7.Disconnect the white/violet wire from the selector switch. With the selector switch in the 120/208- 240V position, check for continuity between the center terminal and the white/violet wire terminal.

If continuity is present as described, the dual voltage selector switch is operating properly.

If continuity is not present as described, replace the dual voltage selector switch.

Removal and Replacement:

1.Disconnect the brewer from the power source.

2.Disconnect the three wires from the selector switch.

3.Remove the switch mounting nut from the under side of component mounting bracket; remove switch from bracket.

4.Install new switch in component mounting bracket and secure with mounting nut.

5.Refer to FIG. 11 when reconnecting wires to the switch.

Location:

The voltage selector switch is located on the component mounting bracket behind the front access panel.

Test Procedure:

1.Disconnect the brewer from the power source.

2.With the voltage selector switch in the 120V posi- tion, connect a voltmeter between the black termi- nal of the terminal block and the center terminal of the selector switch.

3.Connect the brewer to the power source. The indication must be 120 volts ac.

4.Move the voltage selector switch to the 120/208- 240V position, the indication must be 240 volts ac.

5.Disconnect the brewer from the power source.

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

If voltage is not present as described, refer to the Wiring Diagrams and check the brewer wiring har- ness.
