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.
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.
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. (The Warming Zone
element is not controlled by the ESEC). For the user, the
elements are operated by pressing the touch pads for the
surface elements located on the control panel for the desired
settings. The control settings are shown in 2 digital displays.
Hot Surface Indicator Lights - If any of the surface
elements are hot, the "Hot Surface" indicator lights will glow
and remain ON until the cooktop becomes sufficiently cool.
ESEC Lockout Feature ( "- -" ) - The electronic oven
control's Clean and Lock 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
Clean or Cooktop Lockout mode is active. When the oven
control is in a Clean or Cooktop Lockout mode, "- -" will appear
in the ESEC displays to signify that the surface elements are
locked out.
ESEC System Components -
The ESEC system consists of the following components:
• Power Board. The control board mounted is mounted with
standoffs and 2 screws on the lower back of the range.
• UIB or User Interface Board. This circuit board is mounted
with 4 screws in the backguard.
• TSEC or Touch Sensor Electronic Control. The TSEC controls
the touch pads for all surface element controls.
• ESEC Harness connects the ESEC system components and
communicates with the EOC (Electronic Oven Control).

Notes on Replacing Parts
Replacing the Power Board* – When replacing the main control board (power board) on
the back of the range, do not over-tighten the 2 screws that secure the Power Board. A
torque of only 10 in.-lbs. is required to tighten the screws. Over-tightening the screws can
damage the plastic standoffs and possibly the board itself.
Replacing the TSEC – The Touch Sensor Electronic Control includes several parts and
must be replaced as an assembly.
Replacing the UIB* – When replacing the User Interface Board located in the backguard,
do not over-tighten the 4 screws that secure the UIB. To secure the UIB use NO MORE
THAN 20 in. - lbs. Over-tightening these screws can possibly damage the UIB board.
* 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.
