ON/OFF SWITCH
Location:
The ON/OFF switch is located on the left front of
the hood.
Test Procedure:
1. Disconnect the brewer from the power source.
2. Viewing the switch from the back remove the
white wire or red wire from the upper terminal and
the black wire from the center terminal.
3. With a voltmeter, check the voltage across the
white wire or red wire and the black wire. Connect
the brewer to the power source. The indication
must be:
a) 120 volts ac for two wire 120 volt models, three
wire 120/208 or 120/240 volt models.
b) 200 to 240 volts ac for two wire 200 or 240 volt
models.
4. Disconnect the brewer from the power source.
If voltage is present as described, reconnect the white
or red wire and proceed to #5.
If voltage is not present as described, refer to the
Wiring Diagrams
and check the brewer wiring har-
ness.
5. With the black wire removed, remove the white/
red wire from the lower terminal.
6. Check for continuity across the center and lower
terminal with the switch in the "ON" position.
Continuity must not be present when the switch is
in the "OFF" position.
If continuity is present as described, reconnect the
black wire to the center terminal and the white/red to
the lower terminal.
If continuity is not present as described, replace the
switch.
Removal and Replacement:
1. Remove the wires from the switch terminals.
2. Compress the clips inside the hood and gently
push the switch through the opening.
3. Push the new switch into the opening and spread
the clips to hold switch in the hood.
4. Refer to Fig. 7 when reconnecting the wires.
