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.

Never interfere with the proper installation of any safety device.

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.

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

Electric Range with ES 1040 Electronic Oven Control

PN 316904476 Rev A (1305)

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 key to end bake mode.
Temperature Adjustment
1.

While in a non-cooking mode, press and hold the bake key for 6 seconds.

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

Use the number keypad (0-9) to enter the desired amount of adjustment (up to
35°F).

4. Press

the

bake key to change the sign of the adjustment to a (-) if necessary. A

positive adjustment will not display a sign.

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.

Electronic Oven Control Fault Code Descriptions

Fault
Code

Likely failure condition/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.

Replace probe or repair wiring connections if defective.

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.

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 between touch panel and EOC.
3. Test keyboard circuits using test matrix. Replace touch panel if defective.
4. If keyboard circuits check correctly, replace the EOC.

F12

EOC Internal software error or
failure.

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

F13

F14

Keyboard tail failure.

1. Check/reseat ribbon harness connections between keyboard touch panel and EOC.
2. Test keyboard circuits using test matrix (below). Replace touch panel if defective.
3. If keyboard circuits check correctly, replace EOC.

F17

EOC Internal hardware error of
failure.

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

F18

F30

Open oven sensor probe circuit.

Check resistance at room temperature and 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 and 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 and probe connector. If resistance is correct, replace the EOC.

F42

EOC internal software
confi guration error.

Usually this failure code would only appear if the EOC has been replaced with an incorrect version. Verify that the correct replacement part
number is being used.

F50

Internal signal voltage error.

Disconnect power, wait 30 seconds and reapply power. If fault returns when power is reapplied, replace EOC.

F51

Display communication error.

F60

EOC oven temperature. Higher
than normal temperature detected
on the EOC board.

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

Check for blocked ventilation slots in control panel rear cover.

Inspect oven vent for proper assembly and air fl ow.

Verify operation of cooling fan (if present).

F64

Time Base failure. The EOC
cannot determine if connected to
50Hz or 60Hz power supply.

Confi rm that range is connected to proper power source (50Hz or 60Hz). Generators or other portable power supplies and solar grids, etc.,
may not provide proper power supply. If power source is correct, replace the EOC.

F65

Keyboard short circuit or internal
EOC failure.

Test keyboard circuits using test matrix. Replace touch panel if defective.

If keyboard circuits check correctly, replace the EOC

F66

EOC internal power supply failure.

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

F68

High voltage condition. L1 or L2
may be crossed with Neutral on
incoming PS.

Verify proper incoming line voltage and polarity of L1, L2 and Neutral power supply connections at range terminal block.

If power supply voltage and polarity are correct, replace EOC.

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 assembly.

3. If motor runs and switch contacts and wiring harness test correctly, 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.
