1. Disconnect the brewer from the power source.
2. Remove  the  black,  white/violet  and  white/red

wires from the switch terminals.

3. With  a  voltmeter,  check  the  voltage  across  the

black  wire  removed  from  the  TEA/OFF/COFFEE
switch and the white wire remaining on the switch
terminal.

4. Connect the brewer to the power source. The in-

dication must be 120 volts ac for two wire 120
volt models and three wire 120/208 volt models,

5. Disconnect the brewer from the power source.

If voltage is present as described, proceed to #6.
If voltage is not present as described, refer to the 

Wir-

ing Diagrams and check the wiring harness.

minals of the top row when switch is in the "TEA"
position and the center and right terminals of the
top row when the switch is in the "COFFEE” posi-
tion.

If continuity is present as described, replace the wires,
the switch is operating properly.
If continuity is not present as described, replace the
switch.

Removal and Replacement:
1. Remove the wires from the switch terminals.
2. Compress  the  clips  inside  the  hood  and  gently

push the switch through the opening.

3. Push the new switch into the opening and spread

the clips to hold the switch captive in the hood.
