If voltage is present as described, proceed to #4.
If voltage is not present as described, refer to the Wir-
ing Diagrams and check the brewer wiring harness.
4. Check the voltage across the other switch ter-
minal and the terminal on the indicator lamp
with white or red wires with a voltmeter when
the switch is in the upper position. Connect the
brewer to the power source. The indication must
be as described in step 2. Voltage must not be
present across these terminals in the lower posi-
tion.
5. Disconnect the brewer from the power source.
If voltage is present as described the switch is operat-
ing properly.
If voltage is not present as described, replace the
switch.
Removal and Replacement:
1. Compress the clips inside the housing and gently
push the switch through the opening.
2. Remove the wires from the switch terminals.
3. Refer to FIG. 13 when reconnecting the wires.
4. Push the new switch firmly into the opening.
Location:
These switches are located beneath and to the
left of their associated warmers as viewed from the
front, FIG.s 11 and 12.
Test Procedure:
1. Locate the switch terminal with black wires that
do not go to the nearby indicator lamp.
2. Check the voltage across this terminal and the
terminal on the indicator lamp with white or red
wires with a voltmeter. Connect the brewer to
the power source. The indication must be:
a) 120 volts ac for two wire 120 volt models.
b) 200 or 240 volts ac for two wire 200 volt or
240 volt models and three wire 120/240 volt
models.
c) 100 volts ac for two wire 100 volt models.
3. Disconnect the brewer from the power source.
