FIG. 9 WARMER ELEMENT TERMINALS
P1982
Location:
 
The decanter warmers are located in the base of 
the brewer.
Test Procedure:
1.  Disconnect  the  brewer  from  the  power  source 
and remove the three #4-40 screws attaching the 
suspect warmer.
2.  Bring  the  warmer  assembly  out  the  top  of  the 
base.
3.  Disconnect both wires from the warmer. Make sure 
that the wire ends do not touch any metal surface 
of the brewer.
4.  With  a  voltmeter,  check  the  voltage  across  the 
two  wires  removed  from  the  warmer  when  the 
appropriate warmer switch (on/left or right) is in 
the upper position. The voltage must be 120 volts 
ac.
10179 060100
5.  Connect the crewer to the power source.
If voltage is present as described, proceed to #6. 
If voltage is not present as described, refer to the Wir-
ing Diagram and check the brewer wiring harness.
6.  Disconnect the brewer from the power source.
7.  Check for continuity across the two terminals on 
the warmer.
If continuity is present as described, reconnect the 
wires to the terminals, the warmer is operating prop-
erly.
If continuity is not present as described, replace the 
warmer.
Removal and Replacement
1.  Remove  the  three  #4-40  slotted-head  screws 
holding the warmer to the brewer base.
2.  Bring the warmer out the top of the base.
3.  Disconnect both wires from the warmer.
4.  Refer to FIG. 9 when reconnecting the wires and 
orienting the warmers.
5.  Place the warmer into the base and securely attach 
it using the three #4-40 screws.
