To avoid personal injury and/or property damage, it is important that Safe Servicing Practices be
observed. The following are some limited examples of safe practices:
1. DO NOT attempt a product repair if you have any doubts as to your ability to
complete it in a safe and satisfactory manner.
2. Before servicing or moving an appliance:
• Remove the power cord from the electrical outlet, trip the circuit breaker to the
OFF position, or remove the fuse.
• Turn off the gas supply.
• Turn off the water supply.
3. Never interfere with the proper operation of any safety device.
4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE.
SUBSTITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETY
STANDARDS SET FOR HOME APPLIANCES.
5. 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 hazard.
6. Prior to returning the product to service, ensure that:
• All electrical connections are correct and secure
• All electrical leads are properly dressed and secured away from sharp edges,
high-temperature components, and moving parts
• All non-insulated 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
connected
• All panels are properly and securely reassembled
• All gas connections are secure and have been leak tested
ATTENTION!!!
This service manual 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 manual.

SAFE SERVICING PRACTICES

Page 4
Consistently following a standard routine when servicing appliances will insure that you do not
waste time searching for a complex solution to a simple problem. One of the most common mistakes
made by service technicians is failing to verify the incoming power supply to the appliance.
Many times electronic controls and other components are replaced unnecessarily because
the incoming power supply was not veried. When testing the electrical supply the test should be
performed at the terminal block where the power cord or house wiring attaches to the appliance. Verify
that there are 240 volts between L1 & L2 and that there is 120 volts from L1 to Neutral and also from
L2 to Neutral. You should also check the power supply while the appliance is operating or “under load”.
The power supply may check good with the product sitting idle but fail when certain components are
turned on. This can be caused by a weak connection in the customer’s house wiring, or a faulty circuit
breaker or fuse.
Another common mistake is failure to verify all component part wire harness connections. It is
essential that all component connections be checked visually and with the appropriate circuit tester.
Many times components are assumed to be faulty because they do not operate or there is an error
code displayed by the electronic control system. Often the failure is caused by a loose or miswired
connection which can cause the same error code as a defective component part. Newly installed
appliances may have loose connections resulting from shipping and handling conditions or improper
installation. Check the wiring connections before you order replacement parts.
When the repair has been completed the product should be thoroughly tested to verify that the
service performed corrected the problem and that all of the other features and functions of the product
are in proper working order. The extra time taken to do this will create consumer condence in your
efciency and professionalism as well as possibly saving an expensive callback.
SERVICE TIPS - DEVELOP GOOD WORK HABITS
In addition to standard hand tools such as wrenches, screwdrivers, pliers, etc; the following
instruments are considered to be essential equipment for technicians servicing Electrolux cooking
products. Proper testing and diagnostic procedures are not possible without these tools.
•Volt/ohmmeter - Must be capable of voltage measurement from 0 to 500 volts AC and
resistance measurements from 0 to 2 meg-ohms. This usually requires a meter that utilizes
a 9 volt battery. Either digital or analog meters are acceptable however most technicians nd
analog meters easier to use. Appropriate test leads and tips are required to test certain
electronic components and connections.
• Clamp on amp meter - Should be capable of measuring from 0 to 60 amps.
• Temperature Meter - Should be high quality with thermocouple or electronic
“K-type” test probe. Capable of temperature readings up to 1000 degrees Fahrenheit.
Additional instruments that a technician will need to have access to at various times include the
following:
• Combustible gas leak detection meter.
• U tube manometer or equivalent testing device for measuring LP and Natural gas line
pressure on gas ranges. Measurements must be in IWC (inches water column)
• Carbon Monoxide (CO) detection meter capable of measuring from 0-1000 PPM.
• Microwave Leak Detection Meter
NOTE: Electrolux Does Not Supply Tools Or Test Instruments.

PRODUCT OVERVIEW
Electrolux branded freestanding gas ranges are currently available in two distinct model series. The
Wave Touch series and IQ Touch series.
Both designs feature a ve burner cooktop with full width burner grates, a self cleaning main oven
with bake and broil burners, convection and normal bake modes in the main oven, variable speed
convection fan motor, Luxury Glide oven racks, Dual halogen oven lights, and a meat probe.
The Wave Touch models also feature a Perfect Pair™ lower oven capable of baking at temperatures
up to 450 degrees in addition to functioning as a warming drawer.
The IQ Touch models features a lower warming drawer only. The appearance of the Touch Sensor
control panel of the IQ Touch series is also very different from the Wave Touch series as will be seen
later in this manual.
The oven and warmer drawer functions are controlled by the ES630 Electronic Oven Control.
The oven door hinges are designed to allow the door to stand open in virtually any position without
springing closed.
Current nish options available are White , Black and Stainless Steel. Both range models operate on
120 volt 60 hz AC power supply.

The TST system utilizes a touch sensitive glass panel (photo A) to allow the user to control all oven
and warmer drawer operations. 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. It is similar in function to a membrane switch.
The TST control panel generates an electromagnetic eld around each touch pad. When this eld is
interrupted by touching the glass, the control panel communicates the selection information to the
EOC. The EOC then responds by signaling the oven relay board to close the appropriate relays to
perform the selected operation or function.
NOTE: The TST system touch glass is a non serviceable part and must be replaced as a complete
assembly if found to be defective. The replacement glass panel will come attached to the frame and
will include ribbon connectors. (Photo B)
TOUCH SENSOR TECHNOLOGY (TST) CONTROL SYSTEM
The TST control panel has ribbon connectors that link it to the EOC. (Photo C).
If these connectors fail or become loose the TST control panel will not operate and under some
conditions will generate a fault code in the EOC display window.
If the TST control malfunctions or fails to operate inspect and re-seat the ribbon connectors. If a
failure/fault code is present follow the diagnostic procedure for that code.
Troubleshooting The TST Panel
If no fault code appears but the EOC does not
respond when the TST panel is touched then
the cause is either a defective EOC or TST
panel. Replace the EOC rst. If the problem
remains replace the TST panel assembly.
If only a single key is non responsive then the
TST panel is the most likely cause of failure.

When an error or failure occurs in the Electronic Oven Control (EOC) system the control panel will usually
produce an audible beep accompanied by a special display to indicate that there is a failure condition. In order
for a service technician to be able to more easily determine which failure condition has occurred a special
Diagnostic Service Mode has been built in to the control panel software.
To enter the service mode the range must be in the “IDLE” condition meaning that all elements and functions
are turned off. Press and hold the TIMER keypad for the upper oven and the Upper Oven selector keypad for 3
seconds. Always press the TIMER keypad rst immediately followed by the Upper Oven selector keypad.
After three seconds the control panel will enter the service mode and will display the most recent error or
failure codes for the upper and lower ovens as well as the ESEC system.
The control will exit the Diagnostic Service Mode after one minute or it can be ended by pressing the CANCEL
keypad. The service mode can be restarted if necessary by repeating the steps outlined above. While the
control is in the Diagnostic Service Mode the error codes can be cleared from memory by pressing the Upper
Oven Timer keypad. Once they are cleared they can not be recalled.

The photo above shows an IQ Touch control panel that has been programmed into the Diagnostic Service
Mode. The upper oven control is displaying an F11 error code (Stuck Keypad), The lower oven control is
displaying no error code.
The display window to the right of the F11 code is used to display error messages related to the ESEC
(Electronic Surface Element Control) system found in electric ranges. In gas ranges this window will display
E - - in the diagnostic service mode.
Once it has been determined which failure condition is present follow the troubleshooting steps outlined in the
tech sheet and this service manual to correct that specic condition.
.
NOTE: The Diagnostic Service Mode works exactly the same for both IQ Touch and Wave Touch models.

Gas Oven Control
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 control interfaces with the TST (Touch Sensor Technology)
panel to allow the consumer to select the desired function and options.
There are currently two different versions of the TST control panels sometimes referred to as “A” and
“B” versions. Other terms used to refer to the different control styles are: “Wave-Touch™” for the A
model and “ IQ Touch™” for the B model.
The most obvious difference is the appearance of the
control panels when they are in an idle state.
The Wave-Touch™ display panel has a “sleep mode”
that turns off the illuminated control icons on the
touch panel whenever the range is idle for 2 minutes
(Diag A). During this sleep mode only the time of day
will be illuminated in the control panel.
To wake the control simply touch the glass surface.
The touch control keypads will illuminate to allow the
user to program the desired function (Diag B).
Diag.A
Diag. B
The IQ Touch™ display panel has permanent
graphics imprinted in the glass panel and will remain
visible at all times (Diag C).
Diag. C
In current models the Wave-Touch control is always used on ranges that feature the “Perfect Pair™
lower oven”, also referred to as a Mini Oven.
Models that have the IQ Touch control feature a warmer drawer instead of a mini oven.

EOC Troubleshooting and Testing
The Electronic Oven Control system found in the Electrolux freestanding gas ranges uses a separate
oven relay board to power the individual components such as the bake and broil ignitor, lock motor,
warmer drawer or mini 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. The servicer must
follow the troubleshooting and diagnostic information found in this manual and in the product tech
sheet to accurately diagnose any failures and avoid unnecessary parts replacement.
Photo A shows the locations of the EOC Board, Oven Relay Board and Power supply board as seen
from the rear of the range with the rear panel removed. The ribbon connectors to the TST panel can
be seen at the bottom of the EOC circuit board.

EOC SIGNAL VOLTAGE TEST MATRIX
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
like elements, fan motors, lock motors, etc. can be tested with a simple continuity check using an ohm
meter. Verify the continuity of the component and the wiring circuit between the component to the relay
board rst. Also verify continuity of the wiring harness and connectors between the EOC and Oven
Relay Board.
If the component and wiring connections are good, test the output signal voltage from the EOC to the
Relay board for the particular relay that turns on that component part. When testing the output signal
set your volt meter to read DC voltage. The output signal will be approximately 3.3 volts DCV.
Using the EOC SIGNAL VOLTAGE TEST MATRIX it is possible to determine if the EOC is properly
signaling the relay board to turn on a particular component. If the proper signal is detected but the
relay does not close then the relay board is defective and must be replaced. If the proper signal is not
detected then the EOC is defective and must be replaced.
GND (-) CIRCUIT ACCESS POINTS

When testing the signal voltage from the EOC the negative (-) lead of the test meter must connect the
GND circuit on the EOC circuit board. The easiest access point to the GND circuit is located just above
the left corner of the P11 connector. (Photo A).
Photo B demonstrates testing the Bake Relay signal voltage by measuring the voltage output between
connector J7 pin #2 (red wire) and the GND circuit on the EOC circuit board on a gas range.

To achieve optimum cooking results during convection cooking the fan motor speed can be varied.
The EOC will signal the VSC board to speed up or slow down the fan as needed. This speed change
takes place automatically with no action required by the consumer.
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.
Variable Fan Speed
The VSC Board is located on the rear of the range
as seen in photo A. The board varies the voltage to
the convection fan motor as directed by the EOC to
alter the motor speed. The speed control signal and
the power supply to operate the VSC board come
from the EOC through a wiring harness connected
between P2 on the EOC and P1 on the VSC board.
This harness must be intact and properly connected
for the VSC board to operate. If the harness is
defective or not properly connected the EOC will
display a fault code F23.
When testing the VSC board the power supply from
the EOC to the board can be veried by measuring
the voltage between pins 1 & 6 (the two outside pins)
on connector P6 of the VSC board. This connector is
not wired in eld applications and the pins are easily
accessed to test voltage while the other harness
connectors are in place and power is applied to the
range. Test for approximately 5 volts DC (+/- .5 volt)
on these two pins. If the EOC appears to operate
normally but the voltage to the VSC board is incorrect
or if there is no voltage present inspect and test the
wire harness and connectors between the EOC and
VSC board. If the harness is good then the EOC is
defective and should be replaced.

If the convection fan motor fails to run after the oven has been heating for six minutes test for voltage
to the convection fan motor. If no voltage is present then the failure is either in the VSC board, EOC ,
or the wiring in between. If there is proper voltage to the fan motor but it does not run then either the
motor windings are open or the motor is stuck. Test the continuity of the motor windings with an ohm
meter. There should be approximately 15 ohms of resistance in the convection fan motor windings. If
the windings test good inspect the fan blade and motor shaft to see if the motor will turn. Adjust the fan
blade to eliminate binding or replace the motor assembly if the motor shaft is seized.

LUXURY™ Lighting
When the oven door is opened or the LIGHT keypad
on the touch control panel is pressed the interior
oven halogen lights (photo B) 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”.
Photo B
The incremental changing of the oven lights is
controlled by the VSC board. A triac on the board
gradually increases the voltage to the lights over a
2 - 3 second time span until the lights are on at full
power.
If none of the halogen oven lights operate, plug
in the range and open the oven door. Test for
approximately 120 volts AC at pins 1 & 3 of the P2
wire harness connector (brown & white wires) on the
VSC board (photo C).
Always use special care when making live voltage
tests.
If the voltage is correct then the failure is caused by
defective bulbs, sockets or wiring connections.
If the voltage is incorrect the problem could be
caused by a defective door switch, VSC board, or
EOC.
Test the contacts of the oven door switch by
disconnecting the P10 connector on the EOC and
checking for continuity between the grey and pink
wires in the wire harness.
