PRODUCT OVERVIEW Electrolux branded freestanding electric ranges are currently available in two distinct model series. The Wave Touch series and IQ Touch series. Both designs feature a smooth ceramic glass cooktop with electronic surface element controls, self cleaning main oven with hidden bake element, convection and normal bake modes in the main oven, variable speed convection fan motor, Luxury Glide oven racks, Dual halogen oven lights, and meat probe.
TOUCH SENSOR TECHNOLOGy (TST) CONTROL SySTEM The TST system utilizes a touch sensitive glass panel (photo A) to allow the user to control the upper and lower ovens, warmer drawer and cooktop surface elements including the cooktop Warmer Zone element. The TST panel is connected to the electronic oven control (EOC) and the electronic surface element control (ESEC) system UIB (user interface board) via ribbon connectors.
Diagnostic Service Mode When an error or failure occurs in the Electronic Oven Control (EOC) system, or the Electronic Surface Element Control (ESEC) system, the control panel will usually produce an audible beep accompanied by a special display to indicate that there is a failure condition. The manner in which ESEC failures are displayed will vary greatly between the Wave Touch models and the IQ touch models due to the different styles of control panels.
ELECTRONIC SURFACE ELEMENT CONTROL SySTEM (ESEC 30) The ESEC 30 Electronic Surface Element Control System operates the radiant surface elements and warming zone element. The ESEC 30 UIB receives the operator selection from the TST panel and signals the ESEC 20 Surface Unit Control Board (relay board) which then closes the appropriate relay to turn on the desired element.
ERROR CODES - IQ Touch Models When a failure occurs in the ESEC system the control will beep and half of the power level indicator segments for the surface elements will flash in various combinations to indicate which error has occurred. (Fig. 1) The troubleshooting guide provides a listing of the likely failure condition or cause, as well as suggested corrective actions to be taken.
ELECTRONIC OVEN CONTROL (ES630) The Electrolux branded ranges covered in this manual feature the ES630 Electronic Oven Control (EOC) . This control system is comprised of the Electronic Oven Control Board, Oven Relay Board, and Power Supply Board. The ES630 EOC interfaces with the TST (Touch Sensor Technology) panel to allow the consumer to select the desired function and options.
ELECTRONIC OVEN CONTROL (ES630) EOC Troubleshooting and Testing The Electronic Oven Control system found in the Electrolux freestanding electric ranges uses a separate oven relay board to power the individual components such as the bake and broil elements, lock motor, warmer drawer or lower oven element, etc. This is different from some other styles of electronic oven controls where the EOC and control relays are integrated in to a single component.
ELECTRONIC OVEN CONTROL (ES630) If a component part that is controlled by the EOC fails to operate the cause could be due to a defect in the EOC, Oven Relay Board, wiring connections , or the non functioning component. Component parts such as elements, fan motors, lock motors, etc.
POWER SUPPLy BOARDS The EOC and ESEC system are powered by separate power supply boards that are mounted on the rear of the range chassis just below the EOC as seen in photo A. The two Power Supply Boards are identical however one board is designated as PS 1 and the other is PS 2 on the wiring diagram.
VARIABLE SPEED CONTROL The Variable Speed Control (VSC) board operates the Convection Fan as well as the Oven LUXURY™ lighting. In the event that either of these features do not operate properly the VSC board should be examined as a possible source of failure. When testing for convection fan operation it should be noted that on gas ranges there is a six minute delay from the start of the convection cooking cycle until the fan motor will run.
LUxURy™ Lighting When the oven door is opened or the LIGHT keypad Photo A on the touch control panel is pressed the interior oven halogen lights (photo A) come on and brighten gradually. When turned off they dim gradually until they are completely off. This feature is also sometimes referred to as “Ramp Up lighting”.
RACK SENSING SWITCH In order to prevent damage to the extendable telescoping interior oven racks, the EOC will not Mtg. screw perform a self clean cycle until the racks are removed. A rack sensing switch mounted in the rear of the oven liner signals to the EOC that the racks have been removed.
RACK SENSING SWITCH To test the rack sense switch contacts remove the rear Photo A wire cover on the range and access the wire harness connector P10 on the EOC. (Photo A) Unplug the harness and test for continuity between the blue &...
MEAT PROBE FEATURE Theory Of Operation Some models feature a meat probe that is used to monitor the internal temperature of the food during cooking. The meat probe is a RTD (Resistance Temperature Device) similar to the oven temperature sensor found in ranges with electronic oven controls. As the temperature of the meat probe increases the resistance decreases.
COOKTOP & ELEMENTS The procedure for servicing the smooth glass cooktop Photo A and surface elements is similar to other Electrolux manufactured ranges. The front of the cooktop can be lifted by removing the screws that secure it to the range chassis.

Screw Access Remove the drawer per instructions on page 41. Using a ¼” nut driver with magnetic screw holder remove the two screws securing the lower oven chassis to the range chassis.
WARMER DRAWER THEORy OF OPERATION Warmer drawer operation is controlled by the EOC and Oven Relay board. When the warmer drawer is first activated a thermal disk mounted in the drawer cavity is used to detect when the warmer drawer is cold and a call for heat is needed. If the thermal disk is initially closed, the EOC assumes that the warmer drawer is cold.
Replacing Warmer Drawer element & Thermo Disc The warmer drawer element and thermo disc are Harness Connector Plug mounted to a metal base pan which must be removed in order to replace the element. Remove the lower wire shield from rear of the range. Unplug the warmer drawer harness connector and push the connector through the slot in the back panel so that it can be removed with the element and base assembly.
