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.

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 in the same way as with conventional controls, by
pushing in and turning the knob to the desired setting. The setting
is shown in the digital display above the knob, instead of using
graphics on the control panel.
ESEC Hot Element Indicator ("HE") - While an element surface
is hot, that element's display will show "HE". This is in place of the
usual hot surface indicator light on ranges with conventional
controls.
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 Lock mode is active.
When the oven control is in a Clean or Lock mode, "- -" will appear
in the ESEC displays to signify that the surface elements are locked
out. NOTE: The "HE" (hot element) display will always have
priority over the "- -" display.

ESEC System Components - The ESEC system consists of a
Power Board (main control board mounted on the mainback of the

range) and User Interface Board or UIB (circuit boards with digital
displays, mounted in the coontrol panel), four Potentiometers
(push-to-turn control for each element) and the ESEC Harness
that connects the boards and the oven control. The ESEC boards
communicate with each other to control the elements and with the
oven control for the lockout modes. (See the ESEC System
Diagram.)

Notes on Replacing Parts

Replacing Potentiometers – Each of the four push-to-turn controls is mounted to the

control panel with a hex nut and lockwasher. When replacing a potentiometer, do not
over-tighten the hex nut – a torque of only 5 in.-lbs. is required to properly mount the
potentiometer. Over-tightening the hex nut will negatively affect the smooth feel of the
knob turn and can damage the potentiometer.
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.
