BREW TIMER
FIG. 4 BREW TIMER
P1833
Location:
The brew timer is located in the hood. It consists
of the left dial plate and circuit board.
Test Procedure:
1. Disconnect the brewer from the power source.
2. Remove the wires from terminals TL3, TL4, & TL5
of the timer and rotate the dial fully counterclock-
wise.
2. With a voltmeter, check the voltage across termi-
nals TL1 and TL2 when the ON/OFF or SELECTOR
switch is in the “ON” (T3 left, T6 left or right) po-
sition. Connect the brewer to the power source.
The indication must be:
a) 120 volts ac for two wire 120 volt models.
b) 240 volts ac for two wire 240 volt models.
c) 100 volts ac for two wire 100 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 the
Wir-
ing Diagrams
and check the wiring harness.
4. Check for continuity across the white/orange and
white/yellow wires when the start switch is held
in the lower position.
If continuity is present as described, refer to Fig. 5
and reconnect the wires to terminals TL3, TL4, & TL5
of the timer board and proceed to #5.
If continuity is not present as described, refer to the
Wiring Diagrams
and check the wiring harness.
5. Check the voltage across terminals TL1 and TL4
with a voltmeter when the ON/OFF or SELECTOR
switch is in the “ON” (T3 left, T6 left or right) po-
sition and the start switch is momentarily placed
in the lower position. Connect the brewer to the
power source. The indication must be:
a) 120 volts ac for two wire 120 volt models for
approximately twenty seconds and then return
to its previous indication.
b) 240 volts ac for two wire 240 volt models for
approximately twenty seconds and then return to
is previous indication.
c) 100 volts ac for two wire 100 volt models for
approximately twenty seconds and then return to
its previous indication.
6. Disconnect the brewer from the power source.
If voltage is present as described, the timer is operat-
ing properly. Adjust the timer dial as required.
If voltage is not present as described, replace the timer.
Removal and Replacement:
1. Remove all wires from the timer.
2. Remove the circuit board and dial plate from the
brackets.
3. Install the new timer circuit board as described in
the
Late Model Timer
Section.
4. Refer to Fig. 7 when reconnecting the wires.
5. Install the Timer Setting Decal, provided with the
timer replacement kit, to the rear of the schematic,
on the top cover.
5. Adjust the timer as required. Refer to
Late Model
Timer
Section.
