SERVICE DATA SHEET

Appliance with 5xx Electronic Oven Control

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.

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. Substitutions may

not comply with safety standards set for home appliances.

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 moving parts.

•

All uninsulated electrical terminals, connectors, heaters, etc. are ade-

quately spaced away from all metal parts and panels.

•

All safety grounds (both internal and external) are correctly and se-

curely reassembled.

•

All panels are properly and securely reassembled.

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.

TEMPERATURE ADJUSTMENT

1.

While in a non-cooking mode, press and hold the

Bake

key for 6 seconds.

2.

The current calibration offset (temperature adjustment) should appear in the

temperature display.

3.

Use the number keys (0-9) to enter the desired amount of adjustments (up

to 35°F).

4.

Press the

Self Clean

key to change the sign of the adjustment to a (-), if

necessary. A positive adjustment will not display a sign.

5.

Once the desired adjustment (-35° to 35° F) has been entered, press the

Start

key to accept the change or the

Cancel

key to reject the change.

Note:

Changing calibration affects all Baking modes. The adjustments made will

not change the self-cleaning 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 temperature is above apporximately 575°F/302°C.

ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS

Code

Condition / Cause

Suggested Corrective Action

F10

Control has sensed a potential runaway oven con-

dition, 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, disconnect 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.

F13

Control’s internal checksum may be corrupted.

•

Press

CLEAR

key. - Disconnect power, wait 10 seconds, and reapply power. If fault

returns upon power-up, replace EOC.

F14

Misconnected flat cables. No communication be

-

tween 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

or

F31

Open RTD sensor probe/ wiring problem. Note: EOC

may initially display an “F10,” thinking a runaway

condition exists.

Shorted RTD sensor probe /wiring problem.

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 resis-

tance 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.

F90

to

F94

Door motor mechanism failure.

1.

Turn off power for 10 seconds, then turn on power. Test the door latch again (try to start a

Clean cycle).

2.

If it fails, check wiring of Lock Motor, Lock Switch and Door Switch circuits.

3.

Unplug the lock motor from the board and apply power (L1) directly to the Lock Motor. If

the motor does not rotate, replace Lock Motor Assembly.

4.

Check Lock Switch for proper operation (do the contacts open and close, check with ohm

-

meter). The Lock Motor may be powered as in above step to open and close Lock Switch.

If the Lock Switch is defective, replace Motor Lock Assembly.

5.

If all above steps fail to correct situation, replace the EOC.

Note:

Generally speaking, F1X implies a control failure, F3X an oven probe problem, and F9x a latch motor problem

.
