OPERATION AND SERVICE PROCEDURES
AUTOMATIC ELECTRIC RSS380
RC231002 Rev. 3 68
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.
1. 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.
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 buzzer.
3. 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.
4. 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.
5. 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.
