remove the blue wire from the limit thermostat.
2. With a voltmeter, check the voltage across the
blue wire removed from the limit thermostat and

exposed terminal of the limit thermostat and the
white wire on the tank heater terminal when the
control thermostat is turned “ON” (full clockwise).
Connect the brewer to the power source. The
indication must be 120 volts ac.
6. Disconnect the brewer from the power source.
If voltage is present as described, reconnect the black
wire, the limit thermostat is operating properly.
If voltage is not present as described, replace the limit
thermostat.
Removal and Replacement:
1. Remove both wires from the limit thermostat
terminals.
2. Carefully slide the limit thermostat out from under
the retaining clip.
