SERVICE DATA SHEET
Electric Ranges with ES 200/205/300 & 305 Electronic Oven Controls
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.
2.
3.
4.
Before servicing or moving an appliance remove power cord from
electrical outlet, trip circuit breaker to OFF, or remove fuse.
Never interfere with the proper installation of any safety device.
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.
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 to end bake mode.
Temperature Adjustment
1.
2.
3.
4.
5.
Set EOC to bake at 550°F.
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).
Calibration offset should appear in the display.
Use the slew keys to adjust the oven temperature up or down 35°F in 5°F
increments.
Once the desired (-35° to 35°) offset has been applied, press STOP/CLEAR.
Note: Changing calibration affects normal Bake mode. The adjustments made will not
change the Self-Cleaning cycle temperature.

Likely Failure Condition/Cause
F10
Runaway Temperature.
F11
Shorted Keypad.
F12
Bad Micro Identification.
F13
Bad EEPROM Identification/Checksum error.
F30
Open probe connection.
F31
Shorted Probe connection.
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.
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.

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, replace Lock Motor
Assembly.
5. (F90, 91, 92, 93 & 94) Lock Motor continuosly runs - if Micro Switch is open, replace Lock Motor
Assembly.
6. (F92, 93 & 94) Check oven door Light Switch - if open, replace Switch.
7. If all situations above do not solve problem, replace EOC.
