To Set The Controls For A Self-Clean Cycle - Electrolux 30" Service Manual

for cleaning. Be careful not to raise the element more
than 4 or 5 inches from the resting position.

To set the controls for a self-clean cycle:

For satisfactory results use a 2 hour 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:
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.
CAUTION: Use care when opening the oven door
after the self-cleaning cycle. Stand to the side of the
oven when opening the door to allow hot air or
steam to escape.
CAUTION: DO NOT force the oven door open. This
can damage the automatic door locking system.
Use caution when opening the door after the self-
cleaning cycle is completed. The oven may still be
VERY HOT.
How the ES 300 control system works:
The ES 300 electronic oven control system is made up
of four parts that control the bake and broil elements, the
speed bake fan in the oven, (optional) and the locking of
the door in the self-clean cycle.
1. Electronic oven control.
2. Oven temperature sensor.
3. Oven door lock mechanism.
4. Speed bake switch. (optional)
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, and the preheat and oven lights on the control
glow. In the tip of the oven sensor is a positive thermistor
that increases in resistance as the oven temperature
increases. The microprocessor in the EOC reads the
resistance of the oven sensor and compares it with a
programmed temperature set into the control. When the
resistance of the oven sensor indicates the temperature
in the oven is about 10 degrees above the programmed
temperature, the microprocessor opens the relay which
removes power from 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 relay contacts, and provide power to the
element. After the first cycle, the preheat light is turned
off. Then whenever the oven calls for heat the control
cycles the broil element on for seven seconds and the
bake element on for fifty three seconds out of every
minute. This provides top heat during the bake cycle.
Note: The two elements are never on at the same time.
