button (bake or clean) and rotating the time set control to

move the digits back to "0:00". The display will then show

time of day. If in self-clean the program also can be

stopped by pressing the self-clean button a second time.

The display will return to time of day.

BUZZER ALARM

The buzzer alarm sounds at the end of the minute-minder

countdown. It also sounds at the completion of the timed

bake or roasting cycle but not sound at the end of the self-

clean program. The buzzer will sound for one (1) to two (2)

minutes then shut off. It can be silenced manually by

pressing any of the three (3) buttons on the left. Pressing

the "Clean" button will also silence the alarm but then the

three (3) hour clean setting in the displayed would need to

be cleared manually.

DISPLAY

When the range is initially connected to the power source

or after a power interruption, each element of the display

will light momentarily in sequence then momentarily dis-

play four (4) zeros. Following this the display will flash four

(4) eights along with the two (2) left most arrows to indicate

the buttons to be pressed to set the time of day.

Initial power connection or power interruption can be

simulated by pressing in all three (3) left most buttons

simultaneously.

TO AVOID THE RISK OF ELECTRICAL SHOCK,

PERSONAL INJURY OR DEATH DISCONNECT POWER

BEFORE SERVICING, UNLESS TESTING REQUIRES

IT.

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. Selector switch must be

in "OFF" position and latch in open position (non self-

clean). NOTE: With selector switch in "OFF" position and

latch in open position, the timer switch terminals are

disconnected from circuit power sources which could

damage the ohmmeter.

Simulate initial power connector or power interruption

by pressing the three (3) left hand buttons simulta-

neously. Each element of the display should momen-

tarily light in sequence followed by a 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

RX1 range.

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 buzzer.

Connect the ohmmeter set to RX1 range across either

time 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 ten (10) seconds 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.

With ohmmeter connected across one 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 condition.

Allow timer to countdown, oven should start (switches

close) in five (5) minutes. After five (5) more minutes

switches should open, display indicates time of day

and buzzer sounds. Press bake button to silence

buzzer.

Push self-clean button in. The following should take

place immediately - three (3) hours (3:00) should

appear in the display, the letter "C" should appear on

the left side of the display, the oven-on symbol should

also appear on the left and both switches should be

closed. Manually, with "Time Set" control, turn the

digital display down to one (1) minute. Allow the timer

to countdown to 0:00 - display should return to time-

of-day and the switches open.

NOTE: A slight "click" can be heard whenever the

relay switches open or close.
