6. Check for continuity across the center and end
terminals of the top row when the switch is in the
“ON” (left) position.
If continuity is present as described, replace the wires,
the switch is operating properly.
If continuity is not present as described, replace the
switch.
T3 Brewers W/Half Batch Option
1. Disconnect the brewer from the power source.
2. Remove the black wire from the top center switch
terminal.
3. With a voltmeter, check the voltage across the
black wire removed from the selector switch and
the white wire or red wire on the tank heater.
4. Connect the brewer to the power source.The indi-
cation must be:
a) 120 volts ac for two wire 120 volt models.
a) 240 volts ac for two wire 240 volt models.
b) 100 volts ac for two wire 100 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.
6. Check for continuity across the center and left or
right terminals of the top row when the switch is
"FULL" or "HALF" (left or right) position.
If continuity is present as described, replace the wires,
the switch is operating properly.
If continuity is not present as described, replace the
switch.
7. On T3 brewers disconnect the pink and gray wires
from the left and center terminals.
8. Check for continuity across the left and center ter-
minals in rows two, three and four with the switch
in the half batch position.
If continuity is present as described, replace the wires
the switch is operating properly.
If continuity is not present as described, replace the
switch.

black wire removed from the ON/OFF switch and
the white wire remaining on the switch terminal.
4. Connect the brewer to the power source.The indi-
cation must be 120 volts ac for two wire 120 volt
models.
5. Disconnect the brewer from the power source.
