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.

Removal and Replacement:
1.  Remove the three #4-40 screws securing the 

warmer assembly to the brewer.

2.  Lift the warmer assembly from the brewer.
3.    Disconnect the two wires from the warmer element 

terminals.

4.  Remove the two #8-32 nuts securing the warmer 

element to the warmer plate.
