FIG. 10 LIMIT THERMOSTAT
Location:
The limit thermostat is located inside the hood on
the tank lid.
Test Procedure:
1. Disconnect the brewer from the power source.
2. With a voltmeter, check the voltage across the blue
wire on the limit thermostat and the white wire on
the tank heater terminal. Connect the brewer to
the power source. The indication must be 120
volts ac.
3. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #4.
If voltage is not present as described, refer to the Wir-
ing Diagrams and check the wiring harness.
4. Remove the black wire from the limit thermostat.
5. Check the voltage across the exposed terminal of
the limit thermostat and the white wire on the tank
heater with a voltmeter. 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 to the limit thermostat. The limit thermostat is
operating properly.
If voltage is not present as described, replace the limit
thermostat.
