Location:
The temperature probe is inserted through the
tank lid assembly.
Test Procedures:
1. Disconnect the brewer from the power source.
2. With a DC voltmeter, check voltage across the
two wires at J9 on control board (Black probe to
black wire, red probe to white wire. refer to FIG
18-2). Connect the brewer to the power source.
The indication should be
approximately
between
4vdc cool to 1vdc at ready temperature.
3. Disconnect the brewer from the power source.
If voltage is present as described, circuit is working
correctly, check limit thermostat (and TCO on 230V
models).
If voltage is not present as described, proceed to
#4.
4. Disconnect temperature probe from control board.
Check the resistance across the two terminals of
the temperature probe. The indication should be
approximately
between 10.5K cool to 870 at
ready temperature.
If resistance is to specification, replace the control
board.
If resistance is not to specification, replace the tem-
perature probe.
Removal and Replacement:
1. Disconnect the brewer from the power source.
2. Disconnect the two pin connector from control
board.
3. Pull temperature probe out of it's grommet.
4. Install in reverse order.
