SERVICE DATA SHEET

Electric Range with ES 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 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.

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

cancel

keypad to end

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.

To turn the temperature up, use number keys (0-9) to enter desired

adjustment (up to 35°F).

4.

To turn the temperature down, use number keys (0-9) to enter desired

adjustment (up to 35°F).

•

On models with a numeric keypad:

Press the

self-clean

key to change

between + and - value. A positive adjustment will not display a + sign.

•

On models with UP and DOWN arrow keys:

Press the DOWN arrow key

until the display shows - value. 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

keypad to reject the change.

Note:

Changing calibration affects all baking modes. The adjustments made will

not change the self-cleaning temperature.

ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS

Fault

Code

Likely Failure/Cause

Suggested Corrective Action

F10

Runaway Temperature.

Oven heats when no cook cycle is

programmed.

If Oven is cold:

1.

If fault code is present with cold oven test oven temperature sensor probe circuit resistance. 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 Selector Switch.

1.

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

2. Check/reseat ribbon harness connections.

3. Replace the EOC.

F12

EOC internal software error or

failure (some models).

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

F13

F15

EOC internal hardware error or



F16

EOC internal software error or



F17

F18

F30

Open oven sensor probe circuit.

Check resistance at room temperature & compare to RTD Sensor resistance chart. If resistance is correct replace the

EOC. If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring harness between

EOC & Sensor Probe connector.

F31

Shorted oven sensor probe circuit.

Check resistance at room temperature, if less than 500 ohms, replace RTD Sensor Probe. Check for shorted Sensor

Probe harness between EOC & Probe connector. If resistance is correct replace the EOC.

F33

Meat probe temperature sensor

shorted or too hot.

1.

The error is triggered if the meat probe sees a temperature in excess of 392°F.

Make sure the meat probe was not

used in such way that it could have seen such temperature. If the tip of the probe is not inserted in the meat it will

see the cavity temperature, which can be higher than 392°F (depending on the setpoint) and trigger the alarm.

2.

When the meat probe is connected to the socket inside the oven cavity, if the meat probe is not fully inserted into the

socket it may short the contacts and cause the error. Make sure the probe is inserted as much as it can.

3.

Verify meat probe resistance at room temperature. Compare to meat probe resistance chart. If the meat probe does

not match the chart, replace it.

4.

If the above steps failed to correct the problem, replace the oven relay board.

F60

Electronic Oven Control (EOC) over

temperature.

Higher than normal temperature

detected on the EOC circuit board.

1.

Verify proper assembly of backguard panel. Check for damaged or loose panels, brackets, endcaps, etc.

2.

Check for blocked ventilation slots in control panel rear cover.

3.

Inspect oven vent for proper assembly and air ﬂow.

4.

Verify operation of cooling fan (if present).

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 needed.

2.

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

open replace lock motor assy.

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.
