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 Identification.

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 flat cables. No communication

between oven and controls.

1.

Disconnect power. Verify the flat 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

any liability, for injury or damage of any kind arising from the use of

this data sheet.

IMPORTANT NOTE:

This unit includes an EOC (electronic oven

control). This board is not field-repairable.

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 specified 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 five 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.
