Location:
The warmer element(s) is located under the warmer
plate.
Test Procedures:
1. Disconnect the brewer from the power source.
2. With a voltmeter, check voltage across the two
wires at the warmer element with the "ON/OFF"
switch in the "ON" position. Connect the brewer
to the power source. The indication must be 120
volts ac for two wire 120 volt models and three
wire 120/208 and 120/240 volt models, or 230
volts ac for two wire 230 volt models.
3. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #4.
If voltage is not present as described, refer to Wiring
Diagrams and check wiring harness.
4. Check the resistance across the two terminals on
the warmer element. Refer to chart below.
If resistance is to specifi cation, reconnect the two
wires to the warmer element.
If resistance is not to specifi cation, replace the
warmer element.
