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, O󰀨 or 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 sounds (longer may cause F11 shorted keypad alarm).
3. Calibrationo󰀨set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°)o󰀨sethasbeenapplied,PressStop, Clear, O󰀨 or Cancel.
Note: Changing calibration a󰀨ects 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specic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conrmationofcommunicationbetweentheboards.Communicationoccursthroughsoftware
programming on each board. This communication is not detectable by volt ohmmeters. The programming is
self-monitored and the UI displays will show error codes based on detected failures. The individual boards
arenoteldrepairable.Seetheschematicsanddiagramsincludedonthissheetformoreunit-specicdetails.

ESEC system components -
The ESEC system consists of the following components:
ES502I 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 four screws.
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.
Replacing an induction element
Ensure correct coil location.
