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.
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/ Clear
or
Cancel
to
end bake mode.
TEMPERATURE ADJUSTMENT
1.
Set EOC to bake at 550°F.
2.
Within 5 seconds of setting 550°F, press and hold the bake pad for approximately
15 seconds until a single beep is heard (longer may cause
F11
shorted keypad
alarm).
3.
Calibration offset should appear in the display.
4.
Use the slew keys to adjust the oven temperature up or down 35°F in 5°F
increments.
5.
Once the desired (-35° to 35°) offset has been applied, press Press
Stop/
Clear
or
Cancel
.
Note:
Changing calibration affects normal Bake mode. The adjustments made will
not change the Self-Cleaning cycle temperature.
COOKTOP LOCKOUT
(some models)
For some models it may be necessary to unlock the cooktop before servicing. If the
Cooktop Locked Indicator Light is ON then the cooktop has been locked.
To turn the Cooktop Lockout Feature OFF:
1.
BE SURE ALL GAS SURFACE BURNER CONTROLS ARE SET TO THE
OFF POSITION.
2. Press & hold
oven light
until one beep is heard (after 3 seconds). The
Cooktop Locked indicator light will turn OFF and the gas surface burners may be
used normally.
To turn the Cooktop Lockout Feature ON:
1.
BE SURE ALL GAS SURFACE BURNER CONTROLS ARE SET TO THE
OFF POSITION.
2. Press & hold
oven light
until one beep is heard (after 3 seconds). The
Cooktop Locked indicator light will turn ON and the gas surface burners and
functions are locked out until the cooktop is unlocked.

Likely Failure Condition/Cause
Suggested Corrective Action
F10
Check RTD Sensor Probe & harness. 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.
F11
F12
F13
Shorted Keypad
1.
Disconnect power, wait 30 seconds and reapply power.
2.
If fault returns upon power-up, replace EOC.
Bad micro identification
Bad EEPROM identification/Checksum error
F30
Open Probe Circuit
1.
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.
Check resistance at room temperature, if less than 500 ohms, replace RTD Sensor Probe. Check for open
or shorted Sensor Probe harness between EOC & Probe connector.

Test harness from valve lock microswitch
to Cooktop Lockout Board
and from Board
to EOC. Repair
Replace if defective
3.
Replace Cooktop Lockout Board
4.
Replace EOC
IF VALVE LOCKOUT MOTOR DOES NOT RUN:
1.
Test valve lock motor windings. If open replace valve assembly
2.
Test for line voltage to valve lock motor. If voltage is correct replace valve assembly.
3.
Test harness from Cooktop Lockout Board to valve lock motor and from Cooktop Lockout Board to EOC.
Repair / Replace if defective.
4.
Replace Cooktop Lockout Board.
5.
Replace EOC.

Check the wiring between EOC & Lock Motor Micro Switch.
2.
Check the contacts of Micro-Switch on latch motor assembly. If contacts are open when motor cam
depresses switch, replace Lock Motor Assembly.
3.
Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam.
4.
If all situations above do not solve probem, replace EOC.
IF LATCH MOTOR DOES NOT RUN
