Location:
The transformer is located in the brewer base on
the center of the base plate.
Test Procedures:
1. Disconnect the brewer from the power source.
2. Disconnect the black wire from terminal #5 and the
white or red wire from terminal # 6.
3. With a voltmeter check the voltage across the
black and white wire. Connect the brewer to the
power supply. The indication must be:
a.) 120 volts ac for three wire 120/208 volt models
and three wire 120/240 volt models.
b.) 200 to 240 volts ac for two wire 200, 230 or 240
volt models.
4. Disconnect the brewer from the power supply.
If voltage is present as described reconnect the wires
and proceed to #5.
If voltage is not present as described, refer to the
wiring diagrams and check the brewer wiring harness.
5. Disconnect the blue/black wires from terminals #7
and #12 on the transformer.
6. With a voltmeter check the voltage across the blue/
black wires. Connect the brewer to the power
source. The indication must be 24 volts ac.
If voltage is present as described the transformer is
operating properly.
If voltage is not present as described, replace the
transformer.
Removal and Replacement:
1. Disconnect all the wires from the transformer.
2. Remove the two #6-32 screws and the two #6-32
keps nuts securing the transformer to the brewer
base plate.
3. Remove transformer and discard.
4. Install new transformer on the brewer base plate
securing with two #6-32 screws and two #6-32
keps nuts.
5. Refer to Fig. 35 when reconnecting the wires.
