If voltage is not present as described, refer to the Wiring 

Diagrams and check the brewer wiring harness.

5.  With the black wire removed, remove the wire from 

the lower terminal. 

6.  Check for continuity across the center and lower 

terminal with the switch in the "ON" (upper) posi-

tion.  Continuity  must  not  be  present  when  the 

switch is in the "OFF" (lower) position.

If continuity is present as described, reconnect the 

black wire to the center terminal and the remaining 

wire 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.  Remove front end cap.

3.  Compress  the  clips  inside  the  hood  and  gently 

push the switch through the opening.

4.  Push the new switch into the opening and spread 

the clips to hold switch in the hood.

5.  Reinstall front end cap.

6.  Refer to Fig. 7  when reconnecting the wires.

P1918

Location:

 

The ON/OFF warmer switch(es) are located on the  

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 from the upper terminal and the black 

wire from the center terminal.

3.  With  a  voltmeter,  check  the  voltage  across  the 

white wire and the black wire. Connect the brewer 

to the power source. The indication must be:

 

a) 100 volts ac for two wire 100 volt models.

 

b) 120 volts ac for two wire 120 volt models.

4.  Disconnect the brewer from the power source.

If voltage is present as described, reconnect the white  

wire and proceed to #5.
