Open the oven door to the broil stop position
when broiling
.
6. Broil on one side until food is browned; turn and cook
on the second side.
NOTE: Always pull the rack out
to the stop position before turning or
removing food.
7. When broiling is finished, press Clear/Off.
CAUTION: SHOULD AN OVEN FIRE OCCUR, CLOSE
THE OVEN DOOR AND TURN OFF THE OVEN. IF THE
FIRE CONTINUES, USE A FIRE EXTINGUISHER. DO
NOT PUT WATER OR FLOUR ON THE FIRE. FLOUR
MAY BE EXPLOSIVE.
To set the controls for a self-clean cycle:
For satisfactory results use a 2 hour self-clean cycle for
light soils and a 3 hour cycle for average to heavy
soils.
1. Be sure the clock shows the correct time of day.
2. Press Clean . "— — —" appears in the display.
3. Press the Up Arrow until "3:00" appears in the
display for a 3 hour cycle, or press the Down Arrow
until "2:00" appears in the display for a 2 hour cycle.
4. As soon as the Up Arrow or Down Arrow is
released, "CLN" appears in the display.
5. As soon as the controls are set, the motor driven
lock will begin to close automatically and the "LOCK"
indicator light will flash.
DO NOT open the door while
the light is flashing (it takes about 15 seconds for the
oven door to lock).
6. The "LOCK" light will glow until the cleaning cycle is
completed or cancelled, and the oven temperature
has cooled.
When the self-clean cycle is completed:
1. The time of day or “END” will appear in the display
window and the “Clean” and "LOCK" light will continue
to glow.
2. Once the oven has cooled down for about 1 HOUR
and the "LOCK" light has gone out, the oven door can
be opened.
3. If “END” is in the display and the “Clean” indicator
remains on, press
Clear/Off . The time of day will
appear in the display.
NOTE: When the oven is cool, wipe away any residue
or powdered ash with a damp cloth or paper
towel.
Stopping or interrupting a self-cleaning cycle:
If it becomes necessary to stop or interrupt a self-
cleaning cycle.
1. Press Clear/Off.
2. Once the oven has cooled down for about 1 HOUR
and the "LOCK" light has gone out, the oven door can
be opened.
3. Restart the self-clean cycle once all conditions have
been corrected.
How the ES 200 operates:
The ES 200 electronic oven control system is made up
of three parts that control the bake and broil elements,
and the locking of the door in the self-clean cycle.
1. Electronic oven control.
2. Oven temperature sensor.
3. Oven door lock mechanism.
Bake:
When the bake pad is touched, and a temperature is set
with the up or down arrows, the bake relay on the board
closes. This connects one side of the line to the bake
element. In the tip of the oven sensor is a positive
thermistor that increases in resistance as the oven
temperature increases. The microprocessor reads the
resistance of the oven sensor, and compares it with
programmed temperature set into the control. When the
resistance of the oven sensor indicates temperature in
the oven is about 10 degrees above the programmed
temperature, the microprocessor opens the relay, which
removes power from one side of the element. When
power is removed from the element the oven temperature
begins to lower. As the oven temperature lowers the
resistance of the oven sensor decreases. When the oven
drops to about 10 degrees below the programmed
temperature, the resistance of the sensor tells the
microprocessor to close the bake relay contacts, and
provide power to the bake element once again. After the
first cycle the preheat light is turned off and whenever the
oven calls for heat, the EOC cycles the broil element on
for seven seconds and then the bake element on for fifty
three seconds out of every minute. This provides top
heat during the bake cycle. The two elements will never
be on at the same time.
