SERVICE DATA SHEET
Gas Ranges with ES 330/335/340/345/355 Electronic Oven Controls
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 STOP/CLEAR 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.
Note: Changing calibration affects normal Bake mode. The adjustments made will
not change the Self-Cleaning cycle 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 between touch panel and EOC.
3. Test keyboard circuits. Replace touch panel if defective.
4. If keyboard ciruits check good 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
F14
Membrane switch tail missing
or not connected
1. Check/reseat connections between membrane switch, display boards and EOC.
2. Replace the membrane control panel assembly.
3. Replace the EOC.
F20
Communication failure
between EOC & ESEC
system
1. Test harness/connections between P6 (EOC) and P7 (UIB).
2. If harness checks O.K., failure can be caused by faulty UIB or EOC
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.
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.
