To Adjust The Oven Temperature Lower - Electrolux 30" Service Manual

3. Press Start to accept the temperature change and
the display will return to the time of day. Press Clear
Off to reject the change if necessary.

To adjust the oven temperature lower:

1. Press the Bake pad for 6 seconds. "0" will appear
in the display.
2. To decrease the temperature, use the number pads
to enter the desired change and then press Clean.
The temperature may be decreased up to 35° F.
(NOTE: Pressing CLEAN allows the entry of negative
degree change.)
3. Press Start to accept the temperature change and
the display will return to the time of day. Press Clear
Off to reject the change if necessary.
Troubleshooting:
The ES 450 has some self diagnostics built into the
microprocessor to help in troubleshooting the system.
When a failure occurs one of three codes will appear in
the display window: F1, F3 or F9.
F1 code:
An F1 indicates a malfunction in the EOC itself, and the
control should be replaced.
F3 code:
An F3 indicates a defective sensor, electronic oven
control, thermal circuit breaker or the wiring in between.
To determine which part is defective:
1. Disconnect the fifteen pin plug from the back of the
oven control that connects the sensor to the oven
control.
2. With an Ohmmeter, measure the resistance between
pins 14 and 15 in the plug (not on the control board).
If the meter reads around value of the oven
temperature sensor resistance chart shown below,
the oven control is defective. If the meter reads less
than 800 Ohms or more than 3000 Ohms, go to
step 3.
3. Disconnect the harness from the oven sensor and
measure the resistance of the oven sensor. If the
meter reads less than 800 Ohms or more than 3000
Ohms, the oven sensor is defective. If the reading
is correct with the chart go to step 4.
4. Remove the rear cover of the range and connect an
Ohm meter between the terminals of the thermal
circuit breaker. If the meter reads infinity the circuit
breaker is defective. If the meter reads zero the
wiring is defective.

F9 code:
An F9 code indicates the EOC has detected a problem
with the motor door latch assembly. Check the contacts
of the lock switch, wiring to the lock motor assembly,
and the lock motor.
Control will not program:
If the control will not program, check for an open sensor
circuit. If the sensor circuit is good, replace the EOC.
Time bake does not operate:
If the time bake feature does not operate, check to be
sure it is being programmed correctly. If it is being
programmed correctly, then replace the control.
Convection bake:
Neither the fan motor or the assist element operates:
1. Remove power from range. Go to the back of the
electronic oven control and disconnect the 15 pin
plug. With the oven door closed, measure the
resistance between pins 10 and 12 of the 15 pin
plug (in the plug). If the meter reads open, check
the door switch and the wiring from the electronic
oven control to the door switch. If the meter reads
zero go to step 2.
2. Measure the resistance between pins 5 and 7. If
the meter reads around 40 Ohms the control is
defective. If the meter reads infinity either the wiring
to the fan motor and element is open or both the
fan motor and the element are defective.
Fan motor does not operate:
1. If the convection element is heating then the fan
motor itself or the wiring to the fan motor is defective.
Also check for a blocked fan blade.
