SERVICE DATA SHEET
Electric Ranges with ES 100/105 Electronic Oven Control
- 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.
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
•
•
•
Press & hold the BAKE key pad and release after the display shows the
factory temperature setting of 00. If the oven temperature has been
previously adjusted from the factory setting, the latest adjusted value will
appear in the display instead.
You may increase the oven temperature in 5°F increments with each press
of the UP ARROW key pad. You may also adjust the oven temperature
downward in 5°F increments with each press of the DOWN ARROW
keypad (total adjustment range is +35°F to -35° F).
To accept the change, wait until the oven control provides the acceptance
beep (See important notes).
The oven temperature adjustment has been made by the oven control and
the display will return to the time of day.
Important notes:
The oven temperature adjustment may be made if your oven control has been
set for °C (Celsius) temperature display mode. In this case each press of the
UP ARROW or DOWN ARROW key pad will adjust in 1°C increments upward
(maximum +18°C) or downward (maximum -18°C), depending on which
arrow keypad is pressed.
If at any time during the process of adjusting the oven temperature feature
you decide not to make the change, press the CANCEL or CLEAR OFF key
pad once before the acceptance beep.
Note: Only two fault codes are displayed by this control - F1 or F3. Generally, F1 display implies the electronic oven control itself has detected an internal
malfunction. F3 implies the control has detected a sensor probe failure. In either case, an alarm will accompany a displayed F1 or F3.
Fault Code
Likely Failure Condition/Cause
Suggested Corrective Action
F1
1.
Shorted keypad.
1.
2.
Control's internal checksum may have become corrupted.
2.
3.
Control has sensed a potential runaway oven condition. Control
may have shorted relay, RTD sensor probe may have gone bad.
The oven temperature adjustment feature can not be modified if BAKE or
BROIL is active.
3.
Resistance Temperature Detector Scale
Set the electronic oven control for normal baking at 350°F. Obtain an
average oven temperature after a minimum of 5 cycles. Press CANCEL
or CLEAR OFF to end bake mode.

Open RTD sensor probe. Note: The EOC will initially display an F1
for this condition. The EOC thinks a runaway oven condition exists.
Shorted RTD sensor probe. Note: The F3 for shorted probe should
only occur when the oven is active or when an attempt is made to
enter a mode.

p/n 316904421 (0912)
Check resistance at room temperature and compare to RTD sensor
resistance chart. If resistance does not match the chart, replace RTD
sensor probe.
2.
Check resistance at room temperature, if less than 500 ohms, replace
RTD sensor probe.
Likely Failure Condition/Cause
Suggested Corrective Action
F10
Runaway temperature.
F11
Shorted keypad.
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 & 13) Disconnect power, wait 30 seconds and reapply power.
3. (F11 & 13) If fault returns upon power-up, replace EOC.
Fault Code
Bad micro identification.
F13
Bad EEPROM identification/checksum error.
F30
Open probe connection.
F31
Shorted probe connection.

the power is reapplied, replace EOC. Severe overheating may require
the entire oven to be replaced, should damage be extensive.
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.
