SERVICE (cont.)
Location:
The warmer element(s) is located under the
warmer plate.
Test Procedures:
1. Disconnect the brewer from the power source.
2. With a voltmeter, check voltage across the white
wire to the power cord and the white/red, brown/
black or violet wire to the "ON/OFF" switch, with the
"ON/OFF" switch in the "ON" (upper) position. The
indication must be:
a) 100 volts ac for two wire 100 volt models.
b) 120 volts ac for two wire 120 volt models.
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
Wiring
Diagrams
and check brewer wiring harness.
4. Check the continuity across the two terminals on
the warmer element.
If continuity is present as described, reconnect the
white wire and white/red, brown/black or violet wires
on the warmer element.
