ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS
Note: Generally speaking "F1x" implies a control failure, "F3x" an oven probe problem, and "F9x" a latch motor problem.
Code
Condition / Cause
Control has sensed a potential runaway oven
F10
condition. Control may have shorted relay, RTD
sensor probe may have a gone bad.
Shorted Key: a key has been detected as pressed
F11
(for a long period) will be considered a shorted
key alarm and will terminate all oven activity.
Control's internal checksum may have become
F13
corrupted.
F14
Misconnected keyboard cable.
F15
Controller self check failed.
Control had detected a problem with the
F20
communication link with the ESEC.
Open RTD sensor probe/ wiring problem. Note:
F30
EOC may initially display an "F10", thinking a
runaway condition exists.
F31
Shorted RTD sensor probe / wiring problem.

Suggested Corrective Action
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.
1.
Press Cancel key.
2.
If fault returns, replace the keyboard (membrane).
3.
If the problem persists, replace the EOC.
1.
Press Cancel key.
2.
Disconnect power, wait 10 seconds and reapply power. If fault returns upon power-up, replace EOC.
1.
Disconnect power. Verify the at cable connection between the keyboard membrane and the EOC
on J2 and J3.
2.
If the problem persists, replace the EOC.
3.
If the connection is good but the problem persists, replace the keyboard (membrane switch).
Replace the EOC.
1.
Check connection between P6 on EOC and P7 on ESEC-UIB.
2.
If problem persist, replace ESEC-UIB.
3.
If all above steps failed to correct situation, replace EOC.
1.
Check wiring in probe circuit for possible open condition.
2.
Check RTD resistance at room temperature (compare to probe resistance chart). If resistance does
not match the chart, replace the RTD sensor probe.
3.
Let the oven cool down and restart the function
4.
If the problem persists, replace the EOC.

1.
Press Cancel key.
2.
If Cancel key does not eliminate problem, turn off power for 30 seconds, then turn on power.
3.
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.
4.
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.
5.
If all above steps fail to correct situation, replace the EOC in the event of a motor that does not rotate.
1.
Press Cancel key.
2.
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.
3.
If the problem persists, replace the motor door latch assembly.

An E015 error code may indicate the ESEC-UIB is not receiving a synchronization signal from the
ESEC-Relay Board.
Check rst 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.
