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.

Failure 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.

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.

F13 Control's internal checksum may have become

corrupted.

F14 Misconnected keyboard cable Verify connection between display board and touch panel (2 ribbon cables). Make sure the cables are well connected at both ends.

F15 Controller self check failed. Verify if relay board receives 120VAC between J4 pin 1 and 3.

F20 The oven controller has detected a problem with

the communication link to the surface element

controller (ESEC)

F23 The controller failed to communicate with the 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. Let the oven cool down and restart the function.

Note: F30 or F31 is displayed when oven is in active mode or an attempt to enter an active mode is made.

F43 The cooling fan speed, as read by the tachometer

input of the EOC-display board, is abnormally
too slow.

F44 The cooling fan speed, as read by the

tachometer input of the EOC- display board, is
abnormally too fast.

F90 Door motor mechanism failure. Press any key to clear the error.

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.

Press any key to clear the error.

If fault returns, replace the keyboard (touch panel).

If the problem persists, replace the display board.

Press any key to clear the error.

Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace display board.

If the cables are good, replace the touch panel.

If the problem persists, replace the display board.

Verify the wiring between J2 on the relay board and P16 on the display board.

If wiring and 120VAC supply is good replace the display board.

If problem persists replace the relay board.

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 P7).

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.

Verify wiring between P2 on the display board and P2 on the oven lights control board.

If wiring is good, replace oven lights board.

If the problem persists, replace the display board.

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.

If the problem persists, replace the display board.

Determine rst if the problem appears to be caused by a cooling fan not turning or turning slowly or by a problem with the sensing of the fan
speed. Start a Bake and check during the rst 15 seconds if the fan is turning (should feel air owing through the vent above the upper oven door).

If the fan does not appear to be turning or turn slowly check the 120VAC at the fan. If 120VAC is present at the fan motor but the fan does not
turn replace the fan motor. If 120VAC is not present at the fan motor when a Bake is started check the connection to the relay board (J3 pin

7) and Neutral: is there 120VAC on J3 pin 7? Does it reach the fan motor? Is the other terminal of the fan motor connected to Neutral? If the

harness or relay board are faulty replace them.

If the fan appears to be normally turning but an F43 error code is generated, it means there is a problem with the reading of the fan speed
sensor. Make sure the connection of the fan speed sensor is properly made (refer to wiring diagram), between the sensor on the fan and the
EOC- display board.

For trouble-shooting purposes, it is possible to enter a test mode that will indicate on the display the reading of the fan speed in RPM: to enter
the test mode, power-up the unit and within 30 seconds press and hold the upper oven Bake and Broil keys for 3 seconds (until you see all
segments in the screen illuminated). Once in the test mode, pressing the upper oven Light key once will display the fan speed in RPM. In normal
client mode the F43 error is generated for a fan speed below approximately 700 RPM.

Inspect the cooling fan. Does it appear to be turning normally (air ow, noise)? Verify the fan blade is well assembled.

Verify there is nothing blocking the air ow of the fan (that could make the fan turn faster).

Check the 120VAC voltage on the fan. A voltage higher than 120VAC + 10% could make it go too fast.

Make sure the connection of the fan speed sensor is properly made (refer to wiring diagram), between the sensor on the fan and the EOC­display board.

For trouble-shooting purposes, it is possible to enter a test mode that will indicate on the display the reading of the fan speed in RPM: to enter the test
mode, power-up the unit and within 30 seconds press and hold the upper oven Bake and Broil keys for 3 seconds (until you see all segments in the screen
illuminated). Once in the test mode, pressing the upper oven Light key once will display the fan speed in RPM. In normal client mode the F44 error is
generated for a fan speed above approximately 2500 RPM.

If problem persists replace both the fan+sensor assembly and the EOC- display board.

I

f it does not eliminate the problem, turn off power for 30 seconds, then turn on power.

Check wiring of Lock Motor, Lock Switch and Door Switch circuits.

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 display board and/or the relay board in the event of a motor that does not rotate.

If all the above steps fail to correct the situation, replace the display board in the event of a motor that rotates endlessly.
