Warmer Switch(es)
RL: Left Rear, Left Front, Right Rear & Right Front
FIG. 10 WARMER SWITCHES
Location:
These warmer switches are the two at the left and
the left most one on the right of the base as viewed
from the front, FIG. 10. Their knobs are marked Off/
On/Off/On.
To test these switches, access will also be needed
to the terminal block located in the rear of the brewer.
Test Procedure:
1. Check the voltage across terminal L1 and the white
or red wire on the terminal block with a voltmeter.
Connect the brewer to the power source. The
indication must be:
a) 120 volts ac for two wire 120 volt models and
three wire 120/240 volt models.
b) 200 or 240 volts ac for two wire 200 volt or 240
volt models.
c) 100 volts ac for two wire 100 volt models.
2. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #3.
If voltage is not present as described, refer to the Wiring
Diagrams and check the brewer wiring harness.
3. Check the voltage across terminal 1 and the white
or red wire on the terminal block with a voltmeter
when the switch is in the “ON” position. Connect
the brewer to the power source. The indication
must be as described in step 1. Voltage must not
be present across these terminals in the “OFF”
positions.
4. 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. Remove the knob from the switch.
2. Loosen the 5/8” nut on the switch shaft and push
the switch through the opening.
3. Remove the wires from the switch terminals.
4. Refer to FIG. 11 when reconnecting the wires.
5. Securely mount the new switch onto the housing
and reinstall the knob.
