SAFE SERVICING PRACTICES
- ALL APPLIANCES 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
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. Electrolux Home Products

SERVICE TIPS - DEVELOP GOOD WORK HABITS
Consistently following a standard procedure 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 oven controls and other components are replaced unnecessarily
because the incoming power supply was not verified. The technician assumes that the power supply
must be good because the top burners or surface elements work. Most electronic controls must
have a 120 volt power supply before they will operate. This is usually accomplished by supplying
L1 voltage and neutral or ground from the household power supply. On most electric ranges if the
neutral or ground circuit fails the top surface elements will still operate but the electonic control as well
as any other 120 volt components such as the oven lamp, self clean latch motor, and some indicator
lamps will not function.
When testing the electrical supply to an electric range the test should be performed at the
terminal block where the power cord or house wiring attaches to the range. Verify that there are 240
volts to the two outside terminals on the block and that there is 120 volts from each of the outside
terminals to the neutral terminal in the center of the terminal block. You should also check the power
supply while the range is operating or “under load”. The power supply may check good with the range
sitting idle but fail when the elements are turned on. This can be caused by a weak connection in the
customer’s house wiring, or a faulty circuit breaker or fuse.
When servicing a gas range the power supply should be checked at the wall outlet with a plug
in circuit tester or volt meter. Make sure that the outlet is properly polarized and grounded. There
are many good plug-in circuit/polarity testers available that will perform this test quickly and easily.
When testing with a volt meter remember that the narrow slot in the wall outlet is the L1 or voltage
side of the circuit and the wide slot is the neutral. The round or “D” shaped hole is the ground circuit.
A properly polarized 120 volt wall outlet will have voltage between the L1 (narrow slot) and neutral
(wide slot) as well as between L1 and ground (See Fig. 1 below). Do not assume that because the
wall outlet has a ground slot that it is grounded. Check it out! Modern electronic controls must have a
correctly polarized and grounded power supply for proper operation.
Neutral
L1
Ground
Fig. 1
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 when the failure is
caused by a loose or miswired connection. New ranges may have loose connections resulting from
shipping and handling conditions or improper installation. A good example is if the EOC on a new
range can not be programmed it could be due to a faulty temperature sensor probe connection. Most
Electronic Oven Controls will not allow programming if there is no input from the probe. Check it out
before you replace the EOC.
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 confidence in your
efficiency and professionalism as well as possibly saving an expensive callback.

SERVICE TOOLS AND EQUIPMENT
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 find
analog meters easier to use.
• 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

Removing and Replacing Warmer Drawer
Electrical Shock Hazard can occur
and result in serious injury or death.
Disconnect appliance from electric
power before cleaning and servicing
the warmer drawer.
To Remove Warmer Drawer:
1. Turn power off before removing the
warmer drawer.
2. Open the drawer to the fully opened
position.
3. On the right glide you will find a shield
attached with a hex-head screw (see
figure 1). Using a 1/4” socket and
ratchet remove the shield.
4. Locate glide lever on each side of
drawer, pull up on the left glide lever
and push down on the right glide

To Replace Warmer Drawer:
1. Replace shield on the right glide of the
drawer body.
2. Pull the bearing glides to the front of the
chassis glide
(see figure 2).
3. Align the glide on each side of the drawer
with the glide slots on the range.
4. Push the drawer into the range until levers
“click” (approximately 2”). Pull the drawer
open again to seat bearing glides into
position. If you do not hear the levers
“click” or the bearing glides do not feel
seated remove the drawer and repeat
steps 2-4. This will minimize possible
damage to the bearing glides.

EOC Failure / Fault Codes
On freestanding gas and electric ranges manufactured beginning with the serial number date code
VF426 many of the EOC’s will have expanded three digit fault codes. These codes may also appear
in new replacement EOC’s for ranges built prior to this date. Below is a list of possible fault codes
that might appear in the EOC display window. The original two digit fault codes appear in the shaded
boxes followed by the replacement three digit codes.
For each Fault code there is a listing of the likely failure condition or cause, as well as suggested
corrective actions to be taken. Not all fault codes will appear in every model but the fault codes are
universal and have the same meaning regardless of the model that is being serviced
Note: Fault codes are not a foolproof system. Never assume that a part has failed based on a displayed
fault code. An example would be if the EOC is displaying F30 (open sensor), the failure could be caused
by a loose connection or faulty wire harness between the EOC and sensor or the sensor could simply
be unplugged.

SUGGESTED CORRECTIVE ACTION
1. (F10 only) Check RTD Sensor Probe & replace if necessary.
If oven is overheating, disconnect power. If oven continues to
overheat when the power is reapplied, replace EOC. Severe
overheating may require the entire oven to be replaced should
damage be extensive.
2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply
power. If fault returns upon power-up, replace EOC.
3. (F14 only) Re-seat the P12 ribbon connector tail. If fault returns replace EOC (first action); Touch Panel (second action)
F20
Communication failure between EOC and ESEC
system.

control board).
2. If harness checks O.K. failure can be caused by faulty UIB,
surface element control board, or EOC.
F26
Communication failure with mini oven control.
Check harness and connectors from the EOC to mini oven
control board. Check for 15vdc to mini oven control (red & gray
wires). If harness and voltage are good replace mini oven control. If fault returns replace EOC.
F30
Open probe connection.
1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance chart. If resistance does not
match the RTD chart replace RTD Sensor Probe. Check Sensor
wiring harness between EOC & Sensor Probe connector.
F31
Shorted Probe connection
F3
2. (F30 or F31) Check resistance at room temperature, if less
than 500 ohms, replace RTD Sensor Probe. Check for shorted
Sensor Probe harness between EOC & Probe connector.
F40
Cooktop Lockout error.
1. (F40 or F41) Check the wiring.

Warmer Drawer
The purpose of the Warmer Drawer is to keep hot cooked foods at serving temperature. Always start with hot
food. It is not recommended to heat cold food in the Warmer Drawer. All food placed in the Warmer Drawer
should be covered with a lid or aluminum foil to maintain quality.
The operation of the warmer drawer element is controlled by a separate rotary switch on the control panel.
The element cycles on and off at varying rates in relation to the selected setting causing the temperature to
increase or decrease. The actual temperature can also be affected by environmental conditions such as room
temperature, air currents, and customer use. The warmer drawer temperature is not precisely controlled and
variations from the operating temperatures listed below are normal.

Warmer Drawer Theory of Operation
The circuit diagram below shows a typical wiring and control setup for a warmer drawer on an
electric or gas range. The warmer drawer is designed to operate on 120 VAC. The L1 wire on the
warmer drawer switch is connected to L1 in the power supply harness and the L2 wire on the switch
is connected to the neutral circuit in the harness. When the switch is turned on the contacts L1-H1
close connecting the L1 circuit to one side of the warmer drawer element. The contacts L2 - H2
also close completing the neutral circuit to the ½ wave diode which connects to the other side of the
element. This circuit provides approximately 60 volts AC to the element resulting in lower wattage
heat output from the element.
There is a parallel neutral circuit that provides neutral to the element through the Low Limit
Thermostat. This circuit is always closed unless the temperature of the warmer drawer has reached
the cut out point of the low limit thermostat. The purpose of this circuit is to allow the element to
operate at full wattage and bring the drawer up to minimum operating temperature more rapidly. Once
the low limit thermostat opens the circuit from H2 through the diode provides the neutral circuit to the
element.
Troubleshooting Warmer Drawer Operation
The warmer drawer can fail in a variety of ways. If the element fails to heat at all you should test the
switch contacts, element, low limit thermostat and all wiring connections and harness.
If the element heats only at low temperatures then the switch contacts L2-H2, diode, or wire harness
or connections could be open.
If the warmer drawer overheats then the fault could be a shorted diode, low limit thermostat contacts
stuck closed, element or wire harness shorted to ground. On a range that has just been installed it is
also possible that there could be a miswired connection causing the overheat condition.
If it is determined that the diode is shorted then the warmer drawer wire harness must be replaced as
an assembly.

Bake-N-Warm™ DOUBLE OVEN
The Bake-N-Warm Double oven, or “Mini Oven”
as it is commonly referred to, is located in the
area normally used for the storage drawer. It can
be used for baking or as a warmer drawer. See
the photo at right.
The Mini Oven is ideal for cooking foods such
as pizza, casseroles, baked potatoes and frozen
convenience foods. The mini oven temperature
range is from 170º F to 450º F in bake mode,
and from 150º F to 190º F in warmer drawer
mode.
The purpose of the Warmer Drawer feature is to
keep hot cooked foods at serving temperature.
Always start with hot food. It is not recommended to heat cold food in the Warmer Drawer.
Mini Oven Operation
The mini oven utilizes a separate solid state control board and temperature sensor probe to control
oven operation and temperature. The control board incorporates a potentiometer that the customer
rotates to the desired temperature setting. The temperature sensor probe is similar in appearance to
the sensor for the main oven and it has the same resistance/temperature values. The mini oven bake
element operates on 120 volts AC and is mounted beneath the drawer.
When the mini oven control is turned on the relay completes the circuit between P2 and P1 providing
voltage from L1 to one side of the bake element. The other side of the bake element is connected to
the neutral wiring harness of the range terminal block.
The mini oven control is powered by the main oven electronic oven control. When the main oven control is in self clean cycle or when the child safety lock has been activated the power supply to the mini
oven control is interrupted and the mini oven will not operate. If the mini oven is in use at the time that
the self clean cycle begins or the child safety lock feature is activated, the 15 volt DC power supply to
the mini oven control board will be interrupted and the mini oven will cease operation.
Special Notes for ESEC Ranges:The mini oven will not operate when the main oven is set for SelfCleaning or the Oven Control Lockout feature is active. If the mini oven is ON and a Self-Clean or
Oven Control Lockout request is attempted, the EOC will deny the request with a triple beep.

Diagnosing Mini Oven Failure
If the mini oven fails to operate properly follow the same basic diagnostic steps that are used for any
oven. Verify the power supply, check the wiring connections, test the heating element and temperature sensor probe.
Use extreme care when testing
circuits with live voltage present.
If the mini oven control fails to send voltage to the element perform the following tests to determine
the cause of failure.
1. With the range connected to the power supply test for 120 volts AC from the black wire on mini
oven control P2 to neutral or chassis ground. If the voltage is incorrect check the power supply to the
range and the wiring harness between the control and main terminal block.
2. If the voltage is correct to terminal P2 verify that the mini oven control board is receiving the required power supply from the main oven EOC. If the mini oven indicator light glows when the control
is activated then the power supply is good. If the light does not glow test for 15 volts DC at the Red
(+) and Gray (-) wires on the P4 connector of the mini oven control. If the voltage is correct then the
failure is in the mini oven control board. If the voltage is incorrect the failure is in the wiring harness or
the EOC.
3. The mini oven control will beep constantly when it detects a fault condition in the temperature
sensor circuit. This could be caused by a runaway heat condition, open / shorted temperture probe,
faulty probe connection or harness. Test the temperature sensor probe circuit by disconnecting the P3
connector at the control board and measuring the resistance between the two purple wires. The resistance of the mini oven temperature probe is the same as that of the main oven temperature probe. If
the probe circuit and harness are good replace the mini oven control board.

COMPONENT TESTING
Many of the range component circuits can be tested at the EOC wiring harness connections with an
ohm meter. By following the wiring diagram and schematic diagram it is possible to perform continuity
tests on the bake and broil elements, lock motor windings, oven door switch and oven lamp circuits.
When testing for continuity the power supply must be turned off or disconnected and the wire harness
connector(s) for the circuit or component being tested must be unplugged from the EOC.
EXAMPLE: To test the Broil element
circuit unplug the L2 out (orange wire)
and BR (blue wire) from the EOC.
With an ohm meter test for continuity
between these two wires. If the circuit
is open then the broil element may be
defective or there could be a failure in
the wire harness or connection. Refer
to the Component Resistance Chart
on the following page for resistance
values of various components

Troubleshooting Electronic Oven Controls
When an oven with an electronic control detects a failure condition, it usually signals the failure with
an “F” code. These “F” codes are considered by many people to be an indicator as to positively which
part in the circuit has failed (“F1” a defective control, “F3” a defective oven probe, and so on). To the
embarrassment of many servicemen who have believed this, they have installed the indicated part
only to find it did not correct the problem.
To troubleshoot an oven with an electronic oven control that is not operating:
1. Make sure electrical power is being supply to the control. Verify this by testing the voltage
at the control wiring harness.
2. Disconnect power for 30 seconds. If fault returns when power is reconnected continue with
the following steps.
3. Remove electrical power.
4, Go to the back of the control and disconnect the multi-pin plug.
5. Check the wiring diagram to determine which two pins in the plug (not on the EOC) are
connected to the oven sensor.
6. With an Ohmmeter check the resistance between the two pins in the plug that are connected
to the of sensor. At room temperature:
• If the meter reads below 900 Ohms or above 1200 Ohms, remove the sensor from the
oven an check it for resistance. If the resistance of the sensor is the same as reading
at the plug, the sensor is defective.
• If the resistance of the sensor reads between 900 & 1200, the wiring between the
control and the sensor is defective.
•If the meter reads between 900 Ohms & 1200 Ohms check the resistance between one
of the pins going to the sensor and chassis. If the meter reads infinity go to step 3. If
the meter shows continuity, remove the sensor and check from one of its pins to the
case of the sensor. If the meter reads continuity, the sensor is defective. If the meter
reads infinity, the wiring between the control and the sensor is shorted to chassis of the
range.
• From the wiring diagram, determine which wires in the plug is from the door lock switch or
switches. From the diagram determine which of the switches are open or closed when the door
in the unlocked position. With an Ohmmeter check to see if the switch that is shown open is
open and the switch that is shown closed is closed by checking the proper pins in the plug.
7. If the above checks test good and the relay on the board for the selected function is not
closing replace the control.
IMPORTANT: If the oven problem is intermittent you must do the above test when the
oven is malfunctioning.

EOC FAILURE / FAULT CODES
On freestanding gas and electric ranges manufactured beginning with the serial number date code
VF426 many of the EOC’s will have expanded three digit fault codes. These codes may also appear
in new replacement EOC’s for ranges built prior to this date. Below is a list of possible fault codes
that might appear in the EOC display window. The original two digit fault codes appear in the shaded
boxes followed by the replacement three digit codes.
For each Fault code there is a listing of the likely failure condition or cause, as well as suggested
corrective actions to be taken. Not all fault codes will appear in every model but the fault codes are
universal and have the same meaning regardless of the model that is being serviced
Note: Fault codes are not a foolproof system. Never assume that a part has failed based on a displayed fault code. An example would be if the EOC is displaying F30 (open sensor), the failure
could be caused by a loose connection or faulty wire harness between the EOC and sensor or the
sensor could simply be unplugged.
FAULT CODE
F1
LIKELY FAILURE CONDITION/CAUSE
F10
Runaway Temperature.
F11
Shorted Keypad.
F12
Bad Micro Identification.
F13
Bad EEPROM Identification/Checksum error.
SUGGESTED CORRECTIVE ACTION
1. (F10 only) Check RTD Sensor Probe & replace if necessary.
If oven is overheating, disconnect power. If oven continues to
overheat when the power is reapplied, replace EOC. Severe
overheating may require the entire oven to be replaced should
damage be extensive.
2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply
power. If fault returns upon power-up, replace EOC.
F14 Display tail missing/not connected
3. (F14 only) Re-seat the P12 ribbon connector tail. If fault returns replace EOC (first action); Touch Panel (second action)
F20
Communication failure between EOC and ESEC
system.
1. Test harness/connections P4 (EOC) & P11 (Surface element
control board).
2. If harness checks O.K. failure can be caused by faulty UIB,
surface element control board, or EOC.
F26
Communication failure with mini oven control.
Check harness and connectors from the EOC to mini oven
control board. Check for 15vdc to mini oven control (red & gray
wires). If harness and voltage are good replace mini oven control. If fault returns replace EOC.
F30
Open probe connection.
1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance chart. If resistance does not
match the RTD chart replace RTD Sensor Probe. Check Sensor
wiring harness between EOC & Sensor Probe connector.
F31
Shorted Probe connection
F3
2. (F30 or F31) Check resistance at room temperature, if less
than 500 ohms, replace RTD Sensor Probe. Check for shorted
Sensor Probe harness between EOC & Probe connector.
F40
Cooktop Lockout error.
1. (F40 or F41) Check the wiring.
F41
2. (F40 or F41) Replace the Cooktop Lockout Control Board.
3. (F40 or F41) Replace EOC.

ES 510 ELECTRONIC OVEN CONTROL
The ES510 control is found on electric ranges with the ESEC 10R system. It has some unique
features and functions not found on other EOC’s. This section of the manual provides specific
service information for the ES 510 Electronic Oven Control.
The ES510 controls the bake element, broil element, oven light, latch lock motor, convection fan
motor and convection element. The EOC also communicates with the ESEC system in order to
prevent use of the cooktop surface elements while performing a self clean cycle. If the EOC detects
that a surface element is in use it will not allow the operator to program a self clean cycle or cooktop
lockout. If the oven is in a self clean cycle the EOC communicates with the ESEC and the surface
elements are locked out until the clean cycle is completed and the oven door has unlocked. The EOC
also disables the warmer drawer and cooktop warming zone during the self clean cycle.
On ranges with a Bake-N-Warm™ Double Oven (mini oven) the EOC provides the power supply
to the control board for this oven and also communicates with the control to lock out the mini oven
during a self clean cycle or to prevent programming a self clean cycle if the mini oven is in use.
Troubleshooting the ES510 EOC
The ES510 continually performs tests on it’s internal circuits as well as certain external components
and operations. When a failure occurs the EOC will emit an audible signal and display the code
associated with that particular failure.
Following are some examples of displayed Failure Fault Codes. The Failure Fault Code list found
on page 29 provides a full listing of possible fault codes, the likely cause and suggested corrective
action.
F30 ERR If the EOC detects that the oven temperature probe
circuit is OPEN during the initial power up you will not be able to
program the time of day and the EOC will display “F30 ERR” and
the alarm will sound when you attempt to set the time.
F31 If the EOC detects that the oven temperature probe circuit
is SHORTED during the initial power up the EOC will continue to
flash “12;00” in the display accompanied by an audible clicking
of the relay circuit in the EOC. You will not be able to program
the EOC or use the surface elements.
If at any time the EOC detects that the oven temperature probe
circuit resistance is less than 800Ω The EOC will display “F31”
and the alarm will sound.
If either of the above conditions is encountered, turn off the power to the range and test the oven temperature probe circuit.
F10 ERR - The EOC detects a runaway heat condition. Check
RTD Sensor Probe & replace if necessary. If oven is overheating,
disconnect power. If oven continues to overheat when the power
is reapplied, replace EOC. Severe overheating may require the
entire oven to be replaced should damage be extensive.
Page 33
P/N 316439220
F11 ERR - Shorted control keypad. Disconnect power, wait 30
seconds and reapply power. If fault returns upon power-up, replace EOC.
NOTE: This failure code can be induced by holding down on a
keypad for more than 20 seconds.
F20 ERR - Communication failure between EOC and ESEC
system. Test harness/connections P4 on EOC & P11 on Surface
element control board. If harness checks O.K. failure can be
caused by faulty UIB, surface element control board, or EOC.
IMPORTANT NOTES when using the Self-Clean feature:
If a Self-Cleaning-Cycle has started but not finished and a power failure occurs, once power is restored
the Cooktop will remain locked. To unlock the cooktop press and hold the Clock pad for 3 seconds. The
red cooktop lock icon will disappear from the display. Then set for another Self-Clean cycle to finish.

Sales Demo Mode
A sales demo (SD) mode is available in the ES510 control that allows the control panel functions to be
demonstrated without turning on any heating elements. To enter or exit the SD mode disconnect power
to the range. Reconnect the power and within 45 seconds touch the Bake
keypad on the EOC and hold
time
until “sd” appears in the EOC display (approximately 6 seconds). The ESEC display windows will also
display “sd” momentarily and then go blank. The time of day display will blink until the clock is set. In
the Sales Demo mode all control panel and display functions can be demonstrated but the elements
will not heat.
To exit the Sales Demo mode you must repeat the procedure used to enter the Sales Demo mode.
Disconnect the power to the range; reconnect the power and within 45 seconds touch and hold the
Bake
pad until the “sd” display disappears. You can not exit the Sales Demo mode by pressing the
time
Stop/Clear keypad or by resetting the power to the range.

ELECTRONIC SURFACE ELEMENT CONTROL (ESEC) SYSTEM
VERSION 10R
The Electronic Surface Element Control System ,(ESEC), 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. Note that “HE” will be displayed even when the element is turned off until it has sufficiently
cooled down.
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.
Previous versions of the ESEC system utilized a separate UIB / Display board assembly for each side
of the range. The ESEC 10R has only one UIB with attached wiring harnesses to connect to the four
potentiometers
ESEC System Components - The ESEC
system consists of:
A Power Board (surface element control
board mounted on the main back of the range)
B User Interface Board or UIB (circuit board
mounted just below the control panel).
C Four Potentiometers (push-to-turn control
for each element).
D Display Boards (separate assembly for
left and right side consisting of two digital displays and ribbon connector).
E ESEC Harness - Connects the UIB, Power
Board and EOC. The ESEC boards communicate with each other to control the elements and with the oven control for the lockout
modes. (See photo at right.)

P/N 316439220
How The ESEC System Operates
When the user rotates the surface element control knob to the desired setting the User Interface
Board (UIB) responds by displaying the selection on the ESEC display board and communicating the
selection information to the power board. The power board then cycles the surface element on at the
appropriate percentage to the power level selected. In addition the power board communicates to the
Electronic Oven Control (EOC) that the surface element is in use so that the EOC will not be able to
disable the surface elements via the cooktop lockout feature.
It is important to note that the surface element will cycle on and off at varying rates depending on the
selected setting. The cycling of the element is more noticeable on a smoothtop range because the
heating coil is visible through the glass cooktop.
When power is first applied the EOC will display a flashing “12:00” as well as the letters “PF”. The
ESEC display boards will also display “PF” for a few seconds and then go blank (See Photo Below) .
On initial start-up or after a power outage the EOC performs a test of the ESEC system and oven
temperature probe. This test will usually last about 15 seconds during which time the EOC can not be
programmed and the surfaces elements can not be used. Attempting to use the surface elements during this time may result in an audible alarm and “ERR” displayed in the EOC .
If the ESEC system test and oven temperature probe test are good, the EOC will allow the time of
day to be programmed and the oven and surface elements can be used.
Troubleshooting The ESEC System
Whenever a failure occurs in the ESEC system there will be a fault code displayed on the LED display
boards on both sides of the control panel. Some examples are pictured below. For a complete list of
possible ESEC fault codes see the chart provided on the following page.
F5 00 - Communication break between EOC and UIB.
Reset the power the range to see if fault code will clear. If code remains check the
ESEC wiring harness and connectors. If these are good replace the UIB. If failure
returns replace the EOC.
F7 42 - Potentiometer for RF is wrong value.
Test resistance value of potentiometer. If potentiometer has been replaced verify
that the correct part number was used. Check for moisture contamination of potentiometer. If potentiometer is good and correct value replace the UIB.
F7 40 - Potentiometer for RF is open.
Test resistance value of potentiometer. Re-seat potentiometer harness connector.

Servicing ESEC System Components
Potentiometers
There are two different potentiometers that are found
on various ranges with the ESEC10R control system.
These can be easily distinguished by the different
colored housings. The Gray colored potentiometer is
used to control single coil surface elements and the
Black colored potentiometer is used on dual or “expandable” coil elements.

The photos below show the potentiometers and the display boards mounted to the range backguard
panel. The potentiometers are held in place by a hex nut and lock washer. 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.
Hex Nut
To test the resistance value of either potentiometer make sure that the shaft is set to the off position, disconnect the wire harness and use an ohm
meter to measure the resistance between pins 1
& 2 on the potentiometer. The gray potentiometer
should have a resistance of 20KΩ (± 10%) and the
black potentiometer should have a resistance of
10KΩ (± 10%).
To test operation of the potentiometer measure the
resistance between Pin terminal G (center) and
either of the outside pin terminals as the control
shaft is being rotated slowly. There should be a
steady increase or decrease in the measured
resistance as the shaft is turned.
Each potentiometer has positive detents or “stops” that can be felt as the shaft is rotated. The drawings below illustrate the stop positions for the different potentiometers.
The Potentiometer Resistance Table gives the various resistance readings that should be found at
each of the stop positions. Resistance values are approximate and may vary by ±10%.

Display Boards
The display boards are secured to the control panel by the display lenses. The lens is inserted into
the panel from the front and the display board locks onto the lens from behind.
The following instructions explain how to separate the board from the lens and remove the lens from
the control panel without damage.
The board is secured to the lens by two locking tabs (Photo 1) .

Using a non metallic object such as a pen or your
fingertip, gently depress the locking tab pushing
from the outside toward the center of the board
(Photo 2).
Pull the bottom of the board slightly while you are
depressing the tab to release the board. Repeat
for each side of the board.

The board is now free from the lens and
may be replaced (Photo 3).
The display boards are assembled as pairs.
Both boards must be removed for service.

User Interface Board
The UIB is mounted to the rear chassis of the range just below the control panel backguard. Prior to
removing the UIB unplug the wire harness connectors to the display boards and power board.
DO NOT ATTEMPT TO UNPLUG THE HARNESS CONNECTORS TO THE POTENTIOMETERS.
These connectors and harness wires are part of the UIB. Unplug the harness connectors at the potentiometers to replace the UIB.
The UIB is secured to the range with one mounting screw and two snap-lock spacers. There is an additional tubular spacer used to maintain proper distance between the circuit board and range chassis.
When replacing the UIB these spacers and screw must be reused. When replacing the UIB do not
over-tighten the screw. 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.

Troubleshooting The Power Board
The power board controls the cycling of the cooktop surface elements by supplying the L2 side of the
power supply to the element. The L1 side of the power supply is connected to terminal 2a on the element terminal block.
When the user turns the potentiometer to the desired setting the UIB communicates this information
to the power board. The power board then closes the appropriate relays to send L2 voltage to the element. The power board will cycle the element relay on and off at varying rates relative to the chosen
setting on the potentiometer.
If the ESEC system appears to be working properly but the power board fails to send voltage to the
selected element then the relay on the power board may be burned out, stuck open, or the power
board may be defective.
If the surface element continues to heat when the controls are turned off (runaway condition) and the
display boards are blank then the relay for that element is stuck closed. Whenever any of these conditions are encountered the power board must be replaced.

The photo below shows an ESEC Power Board and Remote Relay Board as they appear when installed on a range. When replacing the Power Board or Remote Relay Board do not over-tighten the
screws. 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.

Remote Relay Board
On ESEC models which have a cooktop with four Dual Element Surface burners there is additional
remote Remote Relay Board mounted adjacent to the power board. This board controls the outer ring
of the left rear dual surface element.
If the Remote Relay Board fails to send power to the outer ring of the left rear element the failure
could be caused by a defective Remote Relay Board, faulty wiring harness, or defective Power Board.
The relay may be burned out, stuck open, or the relay board could be defective.
Test the harness between the ESEC power board ( P15) and the Remote Relay Board (P1). If the
harness is good replace the Remote Relay Board.
The circuit diagrams on the facing page show examples of each type of ESEC system. Diagram A
shows an ESEC system without the Remote Relay Board. Diagram B shows an ESEC system with
the Remote Relay Board.
