ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS
SERVICE DATA SHEET
Electric Ranges with ES 530 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.
Note: Generally speaking “F1x” implies a control failure, “F3x” an oven probe problem, and “F9x” a latch motor problem.
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.
Code
Condition / Cause
Suggested Corrective Action
F10
Control has sensed a potential runaway oven
condition. Control may have shorted relay, RTD
sensor probe may have a gone bad.
Check RTD sensor probe and replace if necessary. If oven is overheating, disconnect power. If oven
continues to overheat when power is reapplied, replace the EOC.
F11
Shorted Key: a key has been detected as pressed
(for a long period) will be considered a shorted
key alarm and will terminate all oven activity.
1.
2.
3.
Press Cancel key.
If fault returns, replace the keyboard (membrane).
If the problem persists, replace the EOC.
F13
Control's internal checksum may have become
corrupted.
1.
2.
Press Cancel key.
Disconnect power, wait 10 seconds and reapply power. If fault returns upon power-up, replace EOC.
1.
F14
Misconnected keyboard cable.
2.
3.
Disconnect power. Verify the flat cable connection between the keyboard membrane and the EOC
on J2 and J3.
If the problem persists, replace the EOC.
If the connection is good but the problem persists, replace the keyboard (membrane switch).
F15
Controller self check failed.
Replace the EOC.
F20
Control had detected a problem with the 1.
2.
communication link with the ESEC.
3.
Check connection between P6 on EOC and P7 on ESEC-UIB.
If problem persist, replace ESEC-UIB.
If all above steps failed to correct situation, replace EOC.
F30
Open RTD sensor probe/ wiring problem. Note:
EOC may initially display an "F10", thinking a
runaway condition exists.
F31
Shorted RTD sensor probe / wiring problem.
3.
4.
Check wiring in probe circuit for possible open condition.
Check RTD resistance at room temperature (compare to probe resistance chart). If resistance does
not match the chart, replace the RTD sensor probe.
Let the oven cool down and restart the function
If the problem persists, replace the EOC.
F62
Missing zero-cross signal.
Replace the EOC.
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/Cancel 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/
Cancel.
Note: Changing calibration affects normal Bake mode. The adjustments made
will not change the Self-Cleaning cycle temperature.

Press Cancel key.
Turn power off for 30 seconds then turn power on. If the door motor never stops rotating, or if the
F95 error comes back again, verify wiring of the motor. If wiring is good, replace the EOC.
If the problem persists, replace the motor door latch assembly.
3.
E013
Bad EEPROM.
Replace ESEC-UIB.
E014
Loss of Display tail #0.
Check connection P1 on ESEC-UIB and P1 on ESEC Rotary HI Board (RR).
Loss of Display tail #1.
Check connection P2 on ESEC-UIB and P2 on ESEC Rotary HI Board (RF).
Loss of Keyboard Tail.
Check connection J2 on ESEC-UIB and J8 (RF).
ESEC self test failed.
An E015 error code may indicate the ESEC-UIB is not receiving a synchronization signal from the
ESEC-Relay Board.
Check first if J2 pin 5 on the ESEC-Relay Board is wired to P4 pin 5 on the ESEC-UIB. If wiring is good and
the problem is still there, replace the ESEC-UIB. If the problem persists, replace the ESEC-Relay Board.

Press Cancel key.
If Cancel key does not eliminate problem, turn off power for 30 seconds, then turn on power.
Check wiring of Lock Motor, Lock Switch and Door Switch circuits. 4) Unplug the lock motor from
the board and apply power (L1) directly to the Lock Motor. If the motor does not rotate, replace
Lock Motor Assembly.
Check Lock Switch for proper operation (do they open and close, check with ohmmeter). The
Lock Motor may be powered as in above step to open and close Lock Switch. If the Lock Switch
is defective, replace Motor Lock Assembly.
If all above steps fail to correct situation, replace the EOC in the event of a motor that does not rotate.
