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 2-digit displays.

Hot Surface display message - If any of the induction elements are hot, the hot surface message (HE) will display and remain ON until the cooktop cools.

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:

ES1040 oven/cooktop control (EOC) - circuit board mounted in backguard.

Membrane control panel assembly - User interface that include keypads and LEDs.

Induction control assembly - circuit boards in plastic housings mounted on the range back side on two brackets with four screws.

SERVICE DATA SHEET

Electric Ranges with ES1040 and Induction Smooothop

Notes on replacing parts

Replacing an induction control assembly – When

replacing an induction control assembly on the back of the range, do not over-tighten the 2 screws that secure each Control Assembly to the range or the screws that secure the rear wire shield to the Control Assembly. Over-tightening the screws can damage the plastic housings holding the circuit boards.

Replacing an induction element

Whenever replacing any induction element use only the screws supplied with the range to secure the element to the mounting panel. Never use any other type of screw to attach

the induction element .

Replacing the membrane control panel assembly – The membrane control panel assembly includes several parts and must be replaced as an assembly.

Replacing the ES1040 control* – When replacing the oven/cooktop control in the backguard, DO NOT over tighten the screws that secure it. To secure the board use NO MORE THAN 20

in. - lbs. Over tightening these screws can possibly damage the board.

* 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.

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 System (ESEC) Error Code Descriptions

When a speciﬁ c error condition occurs in the ESEC system a code will be displayed in the electronic control panel. The error codes are displayed as “CO” in the left display followed by the code number in the right display. 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 speciﬁ c failure condition. NOTE: If multiple changing error

codes are displayed check for disconnected wires or cables.
