ELECTRONIC OVEN CONTROL (FAULT CODES) DESCRIPTIONS
Note: Generally speaking “F1X” implies a control failure, “F3X” an oven probe problem, and “F9X” a latch motor problem.
F10 Control has sensed a potential runaway oven condition. Control may have shorted relay, RTD sensor probe may have a
gone bad. 1)
Check RTD sensor probe and replace if necessary. If oven is overheating, disconnect power. If oven continues to overheat
when power is reapplied, replace relay board and/or display board.
F11 Shorted Key: a key has been detected as pressed for a long period and will be considered a shorted key alarm and will
terminate all oven activity. 1)
Press any key to clear the error. 2) If fault returns, replace the keyboard (touch panel). 3) If the problem
persists, replace the display board.
F13 Control's internal checksum may have become corrupted. 1) Press any key to clear the error. 2) Disconnect power, wait 30 seconds
and reapply power. If fault returns upon power-up, replace display board.
F14 Misconnected keyboard cable. 1) Verify connection between display board and touch panel (2 ribbon cables). Make sure the cables are
well connected at both ends. 2) If the cables are good, replace the touch panel. 3) If the problem persists, replace the display board.
F15 Controller self check failed or terminal cutoff open. 1) if the oven controller displays an F15 error code and the ESEC controller
displays an E15 error code at the same time, this is a strong indication that the safety thermostat (thermal cutoff) inside the front console
opened. The primary reason for a safety thermostat to open is a deficiency of the cooling fan. With a ohmmeter, verify if the thermostat
tripped. Reset the thermostat is needed and verify operation of the cooling fan. Note: the safety thermostat, when open, cuts AC power
to the oven relay board (connector J4, pin 1 and 3) and the ESEC relay board (connector J1, pin and 3). 2) An F15 error code on the oven
controller may indicate the oven controller is not receiving a synchronization signal from the relay board. One easy way to determine this
is to power off the unit, power it on and start a Timer for 1 minute before the F15 error code appears. If the timer counts-down normally
then the synchronization signal is okay. If the timer stays at 1:00 and does not countdown, then the synchronization signal is missing. If
the synchronization signal is missing, check first if the oven relay board is receiving 120VAC correctly (J4 pin 1 and 3). Then check the wiring
between connector J2 on the relay board and connector P16 on the oven controller. If AC power and wiring looks good and the problem
is still there, replace the relay board. If problem persists, replace the oven controller. 3) The F15 error code may be caused by an oven
controller failure. If the safety thermostat and synchronization signal have been verified and tested good, replace the oven controller.
F20 The oven controller has detected a problem with the communication link to the surface element controller (ESEC). 1) Is the
ESEC User Interface Board powered on (are the surface element displays showing something)? If not, that is the reason why the oven control
cannot communicate with it (ESEC has no power). Check the 120VAC voltage going in to the ESEC power supply board located in the front
console (connector P1) and the low voltage supply going from the power supply board (connector P2) to the ESEC UIB (connector P8). 2)
Check connections between connector P2 on the oven controller and P9 on the ESEC User Interface Board. This is the communication link.
Verify for continuity. Refer to the wiring diagram. 3) If the above steps failed to solve the problem, replace the ESEC UIB board. 4) If problem
persists replace the oven controller.
F23 The controller failed to communicate with the convection fan and oven lights control board. 1) Verify wiring between P2 on
the display board and P2 on the convection fan and oven lights control board. 2) If wiring is good, replace convection fan and oven lights
board. 3) If the problem persists, replace the display board.
F25 No zero cross signal detected on the convection fan and oven lights control board. 1) Make sure L1 and Neutral are connected
to the convection fan and oven lights control board on connector P2 (P2 pin 3 = neutral / P2 pin 5 = L1). 2) If problem persists, replace the
oven convection fan and oven lights control board.
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. Note: F30 or F31 is displayed when oven is in active mode or an attempt to enter
an active mode is made. 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 display board.
F90 Door motor mechanism failure. 1) Press any key to clear the error. 2) If it does not eliminate the 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. 5) 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. 6) If all above steps fail to correct situation, replace the display
board and/or the relay board in the event of a motor that does not rotate. 7) If all the above steps fail to correct the situation, replace the
display board in the event of a motor that rotates endlessly.
E11 Shorted Keypad. Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up: 1. Replace UIB. 2.
Replace Glass Touch Panel
E13 Bad EEPROM. Replace UIB (User Interface Board).
E14 TST/Display tail missing. Check connection between UIB (connector J2, J3 & J4) & glass touch panel. If connections are good,
replace UIB. If problem persist, replace touch panel.
E15 ESEC self test failed, or thermal cutoff open. 1) If the ESEC controller displays an E15 error code and the oven controller
displays an F15 error code at the same time, this is a strong indication that the safety thermostat (thermal cutoff) inside the front
console opened. The primary reason for a safety thermostat to open is a deficiency of the cooling fan. With a ohmmeter, verify if the
thermostat tripped. Reset the thermostat is needed and verify operation of the cooling fan. 2) An E15 error code on the ESEC may
indicate the User Interface Board is not receiving a synchronization signal from the ESEC relay board. Check first if the ESEC relay
board is receiving 120VAC correctly (J1 pin 1 and 3). Then check the wiring between connector J2 on the ESEC relay board and
connector P6 on the UIB. If AC power and wiring looks good and the problem is still there, replace the UIB board. If problem persists,
replace the ESEC relay board.
