be 12 vdc.
3. Disconnect the brewer from the power source.
If voltage is present as described, circuit is working
correctly,
If voltage is not present as described, proceed to #4.
4. Disconnect two pin connector from motor. Check
the resistance across the two terminals of the
motor. The indication should be
approximately
21.6 - 26.4 .
If resistance is to specification, replace the control
board.
If resistance is not to specification, replace the motor.
Removal and Replacement:
1. Disconnect the brewer from the power source.
