SERVICE DATA SHEET
Electric Ranges with ES 3XX 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, Off or Cancel
to end Bake mode.
ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS
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 sounds (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,
Off or Cancel.
Note: Changing calibration affects normal Bake mode. The adjustments made
will not change the Self-Cleaning cycle temperature.
Modular Control Systems
This appliance is equipped with a modular system of controls. The modular
system consists of various boards which communicate with one another to drive
cooking functions. Oven functions, if available, operate through an oven user
interface (UI or UIB) and an oven relay board. Cooktop functions, if available,
operate through a cooktop UI/UIB and a cooktop relay board. There may be
additional boards which work within the system to drive specific functions (refer
to the schematics and diagrams and this sheet). Low voltage operating and
communications power for the modular boards is provided through the wiring
schemes. The boards that generate low voltage operating and communications
power depend upon the individual control system (refer to the schematics and
diagrams on this sheet). These voltages are only the operational voltages. Do
not use these voltages as confirmation of communication between the boards.
Communication occurs through software programming on each board. This
communication is not detectable by volt ohmmeters. The programming is selfmonitored and the UI displays will show error codes based on detected failures.
The individual boards are not field repairable. See the schematics and diagrams
included on this sheet for more unit-specific details.

If Oven is cold:
1. If fault code is present with cold oven test oven temperature sensor probe circuit resistance. Use RTD scale

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

Electronic Surface Element Control (ESEC)
This range is equipped with an Electronic Surface Element
Control (ESEC), which precisely controls the smoothtop cooking
elements at multiple settings. For the user, the elements are
operated by pressing the touch pads located on the control panel
for the desired settings. The control settings are shown in 1-digit
displays.

ESEC lockout feature - The electronic oven control's selfclean and Cooktop Lockout features will not operate when
a surface element is ON. Conversely, the surface elements
controlled by the ESEC will not operate when an oven control
self-clean or Cooktop Lockout mode is active. When the oven
control is in a self-clean or Cooktop Lockout mode, will appear
in the oven control display to signify that the surface heating
elements are locked out.
ESEC system components The ESEC system consists of the following components:
ES3000 oven/cooktop control (EOC) - circuit boards mounted in
plastic chassis.
Induction control assembly - circuit boards in plastic housings
mounted under the cooktop on a metal tray with six screws.

Induction related alarms are displayed using all 4 displays of the user interface. The Rear
Left display is used to notify the user that the message being displayed is an error and is
represented with an “E” in the display. The Front Left display is used to show which induction
generator board is generating the error.

Notes on replacing parts
Replacing an induction generator board – When replacing an
induction generator board under the cooktop, do not over-tighten
the 2 screws that secure each board to the range. Over-tightening
the screws can damage the plastic housings holding the circuit
boards.

1. The Front Left display showing “1” above indicates that the left generator board is producing
the error. If display shows a “2”, this indicates that the right generator board is producing the
error. If display shows a “0”, this indicates that the issue was generated by the cooktop control
and not the induction generator.
2. The Front Right and Rear Right displays display the actual error. An example of a stuck
cooling fan on the left induction generator board (E164) is shown above.
Replacing the ES3000 control* – When replacing the oven/cooktop control in the backguard,
DO NOT over tighten the screws that secure it. Upper and lower support brackets should be
reinstalled.
* Please note: Electronic boards are very sensitive to static electricity. Static electricity can
permanently damage electronic boards. Before handling these parts, be sure to drain static
electricity from your body by properly grounding yourself.

Electronic Surface Element Control System (ESEC) Error Code Descriptions
When a specific error condition occurs in the ESEC system, a code will be displayed in the electronic control panel as shown in the error notification
in an induction system section. For each Error Code there is a listing of the likely cause or failure condition, as well as suggested corrective actions to be taken.
Always reset the power by disconnecting or turning off the power supply for 30 seconds to see if the failure condition will clear. If the error code returns perform
the steps one at a time in the order listed below to correct the specific failure condition. NOTE: If multiple changing error codes are displayed check for
disconnected wires or cables.

Stuck key 1. If a key was pressed inadvertently for a long time this error code will be displayed. Make sure there is nothing (water, utensils) in contact
with the keyboard. The fault code should go away once the key is released and the Stop key is pressed. If the F011 error comes back
when a key is pressed it means the error condition is still there. If the F011 error does not come back it means the error condition is gone
and the oven can be used.
