Calibration - Electrolux 30" Service Manual

you do not want the broil element to cycle so the oven
door is opened to the broil stop position. If the door is not
opened the broil element will cycle when the set
temperature is reached.

Calibration:

To check oven calibration:
1. Place a thermometer or thermocouple in the
center of the oven.
2. Program the oven for bake and the temperature to
350° F. Allow the oven to cycle three times.
3. Average the highest and lowest readings. The
average should be within 10° of 350° F.
The calibration of the ES 100 system cannot be
adjusted:
1. If the oven temperature calibration is off. Check the
resistance of the oven sensor circuit against the chart
below. If the sensor circuit checks good replace the
control.

Troubleshooting:
The ES 100 has some self diagnostics built into the
microprocessor to help in troubleshooting the system.
When a failure occurs one of two codes will appear in of
the display window: F1 or F3.
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 or the wiring in between. To determine which
part is defective:
1. Disconnect the 6 pin plug from the back of the oven
control that connects the sensor to the oven control.

2237 +/- 18.5
2697 +/- 24.4
2. With an Ohmmeter measure the resistance between
pins 1 and 2 in the plug (not on the control board). If
the meter reads around the value of the oven
temperature sensor shown in the below resistance
chart, 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
reading is less than 800 Ohms or more than 3000
Ohms, the oven sensor is defective. If the reading
is correct with the chart, the harness is defective.
Control will not program:
If the control will not program check for an open sensor
circuit. If the sensor circuit is good replace the control.
Blank Display:
If the display on the oven control is blank and the range
is connected to electrical power:
1. Go to the back of the control and measure the
voltage drop between terminals L1 and 4 of the 6
pin plug. If the meter reads line to neutral voltage(120
VAC) the control is defective. If the meter reads
zero, the wiring in the range is defective.
No heat:
If the control appears to be operating normally but
the bake and broil elements do not heat:
1. Go to the back of the oven control and measure the
voltage drop between terminals BA and pin 4 of the
6 pin plug (neutral) with the control not programmed
(clock operating only). If the meter reads line to
neutral (120 VAC) the control is defective. If the
meter reads zero the thermal circuit breaker or the
wiring from L2 is defective. Go to step 2.
2. Remove the back panel from the range to gain
access to the terminals of the thermal circuit breaker.
