Electronic Oven Control (EOC) Fault Code Descriptions
Code Condition / Cause Suggested Corrective Action
F10 Control has sensed a potential runaway oven
condition, control may have shorted relay, and/
or RTD sensor probe may have gone bad.
Check RTD sensor probe and replace, if necessary. If oven is overheating, dis-
connect power. If oven continues to overheat when power is reapplied, replace
the Electronic Oven Control (EOC).
F11 Shorted Key: A key has been detected as
pressed (for a long period). Will be considered
a shorted key alarm and will terminate all oven
activity.
1. Press STOP key.
2. If the problem persists, replace the EOC.
F12 Bad Micro Identication. 1. Disconnect power, wait 30 seconds and reapply power.
2. If fault returne upon power-up, replace EOC
F13 Control’s internal checksum may be corrupted. 1. Press CLEAR key.
2. Disconnect power, wait 10 seconds, and reapply power.
3. If fault returns upon power-up, replace EOC.
F14 Misconnected at cables. No communication
between oven and controls.
1. Disconnect power. Verify the at cable connection between the touch panel
or membrane and the EOC on P12 and P13.
2. If the problem persist, replace the EOC.
F30 Open RTD sensor probe/ wiring problem. Note:
EOC may initially display an “F10,” thinking a
runaway condition exists.
1. Check wiring in probe circuit for possible open or short condition.
2. Check RTD resistance at room temperature (compare to probe resistance
chart). If resistance does not match the chart, replace the RTD sensor
probe.
3. Let the oven cool down and restart the function.
4. If the problem persists, replace the EOC.
F31 Shorted RTD sensor probe /wiring problem.
F90 Maximum oven door unlock time exceeded. 1. Check the wiring between EOC and Lock Motor Micro Switch
2. Replace the Motor Door Latch assembly if necessary.
3. Check for binding of the Latch Cam, Lock Motor Rod and Loc Motor Cam
4. Check to see if Lock Motor Coil is open. If open, replace Lock Motor As-
sembly.
5. Lock Motor continuously runs - if Micro Switch is open, replace Lock Motor
Assembly.
6. (F92, 93, & 94) Check oven door Light Switch - if open, replace Switch.
7. If all situations above do not solve problem, replace EOC.
F91 Maximum oven door unlock attempts exceed-
ed.
F92 Maximum oven door open time exceeded.
F93 Maximum oven door lock time exceeded.
F94 Maximum oven door lock attempts exceeded
Note: Generally speaking, F1X implies a control failure, F3X an oven probe problem, and F9x a latch motor problem.
NOTICE: This service data sheet is intended for use by persons
having electrical and mechanical training and a level of knowledge
of these subjects generally considered acceptable in the appliance
repair trade. The manufacturer cannot be responsible, nor assume

SAFE SERVICING PRACTICES
To avoid the possibility of personal injury and/or property damage, it is
important that safe servicing practices be observed. The following are
some, but not all, examples of safe practices.
1. Do not attempt a product repair if you have any doubts as to your
ability to complete it in a safe and satisfactory manner.
2. Before servicing or moving an appliance, remove power cord
from electric outlet, trip circuit breaker to Off, or remove fuse.
3. Never interfere with the proper installation of any safety device.
4. Use only replacement parts specied for this appliance. Substitu-
tions may not comply with safety standards set for home appli-
ances.
5. Grounding: The standard color coding for safety ground wires is
green or green with yellow stripes. Ground leads are not to be
used as current carrying conductors. It is extremely important
that the service technician reestablish all safety grounds prior
to completion of service. Failure to do so will create a potential
hazard.
6. Prior to returning the product to service, ensure that:
• All electric connections are correct and secure.
• All electrical leads are properly dressed and secured away
from sharp edges, high-temperature components, and mov-
ing parts.
• All uninsulated electrical terminals, connectors, heaters, etc.
are adequately spaced away from all metal parts and panels.
• All safety grounds (both internal and external) are correctly
and securely reassembled.
• All panels are properly and securely reassembled.

SERVICE DATA SHEET
Gas Wall Oven with ES300/305 Electronic Oven Control
OVEN CALIBRATION
Set the electronic oven control for normal baking at 350°F. Allow oven
to preheat to set temperature. Obtain an average oven temperature
after a minimum of ve cycles. Press the STOP key to end the Bake
mode.
ADJUSTING THE OVEN TEMPERATURE
1. Press Bake.
2. Set the temperature to 550°F (287°C) by pressing and holding
the UP key.
3. Within 2 seconds, press and hold Bake until the 2 digit display
appears. Release Bake. The display now indicates the amount
of degrees offset between the original factory temperature setting
and the current temperature setting. If the oven control has the
original factory calibration, the display will read “0”.
4. The temperature can now be adjusted up or down 35°F (17°C),
in 5°F steps by pressing and holding the UP or DOWN keys.
Adjust until the desired amount of offset appears in the display.
When lowering the oven temperature, a minus sign (-) will appear
before the number to indicate that the oven will be cooler by the
displayed amount of degrees.
5. When you have made the desired adjustment, press Stop to go
back to the time of day display.
Note: Oven temperature adjustments made will not change the
Self-Cleaning feature temperature.
2-SPEED COOLING FAN
The EOC controls the speed of the cooling fan. The cooling fan is
activated at low speed during any cooking function and will remain on
until the oven is cooled down. The high speed is activated during the
broil (with open door) and during clean cycles only when the tempera-
ture is above apporximately 575°F/302°C.
