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 examples, but without limitation, of

such practices.

1.

Before servicing or moving an appliance remove power

cord from electrical outlet, trip circuit breaker to OFF, or

remove fuse.

2.

Never interfere with the proper installation of any safety

device.

3. 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 safety hazard.

4.

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 adequately spaced away from all metal parts and

panels.

• All safety grounds (both internal and external) are correctly

and securely reassembled.

SERVICE DATA SHEET

Electric Wall Oven with 3XX Electronic Oven Controls

Oven Calibration

Set the electronic oven control for normal baking at 350°F.

Obtain an average oven temperature after a minimum of 5

cycles.

Press

Stop/Clear/Cancel

to end bake mode.

Temperature Adjustment

1.

Set EOC to bake at 550°F.

2.

Within 5 seconds of setting 550°F, press and hold the bake

pad for approximately 15 seconds until a single beep is

heard (longer may cause

F11

shorted keypad alarm).

3.

Calibration offset should appear in the display.

4.

Use the slew keys to adjust the oven temperature up or

down 35°F in 5°F increments.

5.

Once the desired (-35° to 35°) offset has been applied,

press

Stop/Clear/Cancel

.

Note:

Changing calibration affects normal Bake mode. The

adjustments made will not change the Self-Cleaning cycle

temperature.

F10

Runaway temperature

Oven heats when

no cook cycle is pro-

grammed.

If Oven is cold:

1.

If fault code is present with cold oven test oven temperature sensor probe circuit resis-

tance. Use RTD scale found in the tech sheet.

2.

Replace probe or repair wiring connections if defective.

3.

If temperature sensor probe circuit is good but fault code remains when oven is cold,

replace the EOC.

If Oven is overheating:

1.

If oven is severely overheating/heating when no cook cycle is programmed test oven

temperature sensor probe circuit resistance using the RTD scale found in the service

tech sheet. Also verify that the temperature sensor probe in properly installed in the oven

cavity.

2.

Disconnect power from the range, wait 30 seconds and reapply power. If oven continues

to heat when the power is reapplied, replace the EOC.

NOTE:

Severe overheating may require the entire oven to be replaced should damage be

extensive.

F11

Shorted keypad or selec-

tor switch

1.

Reset poor supply to range - Disconnect power, wait 30 seconds and reapply power.

2.

Check/ reset ribbon harness connections between touch panel and EOC.

3.

Test keyboard circuits. Replace touch panel if defective.

4.

If keyboard circuits check good, replace the EOC.

F13

Shorted oven sensor

probe circuit.

1.

Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up,

replace EOC.

F14

Keyboard tail failure

1.

Check for damage to the ribbon connection or that it is plugged in properly.

F30

Open oven sensor probe

circuit.

1.

(F30) Check resistance at room temperature & compare to RTD Sensor resistance chart.

If resistance does not match

the RTD chart, replace RTD Sensor Probe. Check Sensor

wiring harness between EOC & Sensor Probe connector.

2.

(F31) Check resistance at room temperature, if less than 500 ohms, replace RTD Sen-

sor Probe. Check for shorted Sensor Probe harness between EOC & Probe connector. If

resistance is correct, replace the EOC.

F31

Shorted oven sensor

probe circuit.

F90

Door lock motor or latch

circuit failure.

If lock motor runs:

1.

Test continuity of wiring between EOC and lock switch on lock motor assy. Repair if need-

ed.

2.

Advance motor until cam depresses the plunger on lock motor switch. Test continuity of

switch contacts. If switch is open replace lock motor assembly.

3.

If motor runs and switch contacts and wiring harness test good, replace the EOC.

If lock motor does not run:

1.

Test continuity of lock motor windings. Replace lock motor assembly if windings are open.

2.

Test lock motor operation by using a test cord to apply voltage. If motor does not operate,

replace lock motor assy.

3.

If motor runs with test cord check continuity of wire harness to lock motor terminals. If

harness is good, replace the EOC.
