Location:
The hot coffee brew timer is located in the hood on
the left side. It consists of a 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 TEA/OFF/COFFEE
switch is in the “COFFEE” position. Connect the
brewer to the power source. The indication must
be 120 volts ac for two wire 120 volt models and
three wire 120/208 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, 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. With a voltmeter, check the voltage across termi-
nals TL1 and TL4 when the TEA/OFF/COFFEE
switch is in the “COFFEE” position and the START
switch is momentarily placed in the lower posi-
tion. Connect the brewer to the power source.
The indication must be 120 volts ac for two wire
120 volt models and three wire 120/208 volt mod-
els for approximately twenty seconds and then re-
turn 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
Late Model Timer
section on the following pages.
4. Refer to Fig. 9 when reconnecting the wires.
5. Install the Timer Setting decal, provided with the
replacement timer kit, to the rear of the schematic,
on the top cover.
6. Adjust the timer as required. Refer to
Late Model
Timer
section on the following pages.
