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.

Electonic Oven Control Fault Code Descriptions
Fault Code
Likely Failure Condition/Cause
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.
3. (F11, 12 & 13) If fault returns upon power-up, replace EOC.
F10
Runaway Temperature.
F11
Shorted Keypad.
F12
Bad Micro Identification.
F13
Bad EEPROM Identification/Checksum error.
F15
Internal Control or Power Supply failure between
Power Supply Board & EOC.
1. Check harness connectors at P2 on (Power Supply Board) & J2 connectors on (EOC).
2. If harness and connections are good replace (Power Supply Board).
3. If Power Supply Board is good replace (EOC).
Temperature Adjustment
1. While in a non-cooking mode, press and hold the BAKE key pad for 6 seconds.
2. The current calibration offset (temperature adjustment) should appear in the temperature display.
3. Use the number key pads (0-9) to enter the desired amount of adjustment (up to 35°F).
4. Press the CLEAN key pad to change the sign of the adjustment to a (-) if necessary. A positive adjustment will not display a sign.
5. Once the desired adjustment (-35° to 35° F) has been entered, press the START key pad to accept the change or the STOP or CLEAR
key pad to reject the change.
F20
Communication failure between EOC & ESEC system
(for electric range models ONLY)
1. Test harness/connections P4 (EOC) & P7 (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 Board.
(for models equipped with Bake-n-Warm™ ONLY)
1. Check harness & connectors from the EOC to Mini Oven Control Board. Check for 15VDC
to Mini Oven Control Board (red & gray wires). If harness and voltage are good replace Mini Oven
Control Board. If fault returns replace the EOC.
F30
Open Probe or connection.
Note: Changing calibration affects all Baking modes. The adjustments made will not change the self-cleaning temperature.
F31
Shorted Probe or 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.
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.
F90
Maximum oven door unlock time exceeded.
F91

Oven Calibration
Set the electronic oven control for normal baking at 350°F. Obtain an average oven temperature after a minimum of 5 cycles. Press STOP
or CLEAR keypad to end Bake mode.

1. (F90, 91, 92, 93 & 94) Check the wiring between EOC & Lock Motor Micro Switch.
2. (F90, 91, 92, 93 & 94) Replace the Motor Door Latch assembly if necessary.
3. (F90, 91, 92, 93 & 94) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam.
4. (F90, 91, 92, 93 & 94) Check to see if Lock Motor Coil is open. If open, repl;ace Lock Motor
Assembly.
5. (F90, 91, 92, 93 & 94) Lock Motor continuosly runs - if Micro Switch is open, replace Lock Motor

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 feature 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
mode is active. When the oven control is in a Clean 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 (control board mounted on the mainback of the range) and User
Interface Board or UIB (main circuit board mounted in the control panel), four
Potentiometer Display Boards (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 on reverse side of this Service Data Sheet).

Notes on Replacing ESEC Parts
*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.
Replacing Potentiometer/Display Boards * – Each of the four push-to-turn controls (Potentiometer/Display Boards) are 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.
NOTE: Both Potentiometer/Display Boards must be replaced in pairs (LH or RH sides) at the same time.
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.
Replacing the UIB * – When replacing the UIB, DO NOT over-tighten the 2 screws that secure the UIB.
