5. At the end of the clean cycle the oven will turn off and
the timer will display the time of day. No alarm will
sound.
6. After the clean cycle, turn the selector switch to
"MANUAL" and the oven control to "OFF".
The oven door can be opened approximately thirty
(30) minutes after the completion of the clean cycle.

TIMER TESTING
The electronic digital timer can be tested operationally and
electrically.
OPERATIONAL TEST
This test procedure requires power applied (120 VAC)
either in the range or with 120 VAC line cord connected to
terminals 1 and 2 for bench test. An ohmmeter or continu-
ity tester should be alternately connected across switch
terminals 11 to 12 and 13 to 14. Disconnect wire leads from
terminals 11 to 12 and 13 to 14.
1. Press the three (3) left hand buttons simultaneously.
Each element of the display should momentarily light
in sequence followed by momentary four (4) zeros
and then four (4) eights and two (2) arrows flashing.
Ohmmeter checks across switch contacts 11 to 12
and 13 to 14 should indicate open switches (infinite or
very high ohms). Ohmmeter should be on RX 1
range.
2. Reset time-of-day on display (press in two (2) left
buttons and turn "TIME SET" knob). Push in minute
timer button (far left) and program five (5) to ten (10)
seconds in display. Timer switches should indicate
open condition on ohmmeter. Alarm buzzer should
sound at the end of the countdown. Push minute
minder button to stop the alarm.
3. Connect the ohmmeter set to RX1 range across either
timer switch 11 to 12 or 13 to 14. Press in the "BAKE"
button and hold. Meter should indicate open switch
(infinite or very high ohms). While holding button in,
set approximately one (1) minute on the display.
Meter needle should swing to zero (0) ohms indicating
switch closed. Repeat the procedure after transfer-
ring the test leads to the other switch. Allow count-
down to complete, buzzer should sound. Push button
in to silence buzzer. Display should return to time of
day.
4. With ohmmeter connected across one (1) of the
switches and set to RX1 range, push in the "STOP"
button and program time of day plus ten (10) minutes.
Meter should indicate switches are open. Push in
"BAKE TIME" button - switches should still remain
open. With "BAKE TIME" button held in, program five
(5) minutes. Switches should still show open condi-
tion. Allow timer to countdown, oven should start
(switches close) in five (5) minutes. After five (5)
more minutes switches should open, display indi-
cates time of day and alarm sounds. Press bake
button to silence alarm.
