3. By using the up or down arrows the calibration
temperature can be changed + or - 35 degrees.
4. When the desired calibration is reached, touch the
cancel pad to return the control to normal operation.
TROUBLESHOOTING
The ES 200 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 all the display windows: F1, F3 or F9.
F1 code:
F1 indicates a malfunction in the control itself, and the
control should be replaced.
F3 code:
F3 indicates a defective sensor, electronic oven control
or the wiring in between. To determine which part is
defective:
1. Disconnect the 15 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 12 and 13 in the plug (not on the control
board). If the meter reads around the value of the
oven temperature sensor 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 the same as that in step two the oven
sensor is defective. If the reading is correct with
the chart the harness is defective.

F9 code:
F9 code indicates the control 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 control.
Blank Display:
If the display on the oven control is blank, with the
range connected to electrical power:
1. Go to the back of the control, disconnect the 15 pin
plug and measure the voltage drop between pins 4
and 5 in the 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 burners do not heat:
1. Program the control for bake and check to see if
the bake igniter is glowing. If the igniter is not
glowing, go to step 3. If the igniter is glowing check
the manual gas shut-off for the oven to be sure gas
is being supplied to the safety valve. Then remove
the bake igniter, connect it to 120 VAC and measure
the current flow through the igniter. If the current
flow is less than 3.2 amps replace the igniter. If the
current flow is 3.2 or more check the wiring in the
bake circuit for a poor connection.
2. Program the control for broil and check to see if the
broil igniter is glowing. If the igniter is not glowing
go to step 4. If the igniter is glowing remove the
igniter, connect it to 120 VAC and measure the
current flow through the igniter. If the current flow is
less than 3.2 amps replace the igniter. If the
current flow is 3.2 or more check the wiring in the
broil circuit for a poor connection.
3. Go to the back of the oven control, disconnect the
15 pin plug from the control and measure the voltage
drop between pins 1 and 4 in the 15 pin plug. If the
meter reads 120 VAC the control is defective. If the
meter reads zero the bake igniter, safety valve or
the wiring in the oven circuit is open. Go to step 5.
4. Go to the back of the oven control, disconnect the
15 pin plug from the control and measure the voltage
drop between pins 2 and 4 in the 15 pin plug. If the
meter reads 120 VAC the control is defective. If the
meter reads zero the broil igniter, safety valve or the
wiring in the broil circuit is open. Go to step 5.
5. Disconnect the wires from the igniter and check it
for continuity with an Ohmmeter. If the meter reads
