SERVICE DATA SHEET
ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS
Appliance with ES630 Electronic Oven Control
Note: Generally speaking “F1X” implies a control failure, “F3X” an oven probe problem, and “F9X” a latch motor problem.
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.
Oven Calibration
Set the electronic oven control for normal baking at 350°F. Allow oven to preheat to set
temperature. Obtain an average oven temperature after a minimum of five cycles. Press the
STOP key to end the Bake mode.
IMPORTANT NOTE: This unit includes an EOC (electronic oven control). This board is not
field-repairable.
Temperature Adjustment
1.
Press USER PREFERENCES until you get the UPO menu page.
2.
To select the oven you want to adjust, press USER PREFERENCES again to toggle
between the upper and lower display.
3.
Enter the temperature by pressing the HI or LO keys. The temperature can only be
adjusted by ±35°F (°C).
4.
Press START to accept the changes and go back to USER PREFERENCES menu
display.
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 some, but not all, examples of safe practices.
1.
2.
3.
4.
5.
6.
Do not attempt a product repair if you have any doubts as to your ability to complete it
in a safe and satisfactory manner.
Before servicing or moving an appliance, remove power cord from electric outlet, trip
circuit breaker to Off, or remove fuse.
Never interfere with the proper installation of any safety device.
Use only replacement parts specified for this appliance. Substitutions may not comply
with safety standards set for home appliances.
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 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.
•
All panels are properly and securely reassembled.
2-Speed Cooling Fan
The EOC controls the speed of the cooling fan. The cooling fan is activated at low speed
during any cooking function and will remain on until the oven is cooled down. The high speed
is activated during the broil (with open door) and during clean cycles only when the temperature is above apporximately 575°F/302°C.

ANALYSIS
MATRIX
The cooling fan speed, as read by the tachometer
input of the EOC-display board, is abnormally
too slow.
If wiring is good, replace oven lights board.
Check wiring in probe circuit for possible open condition.
Let the oven cool down and restart the function.
Check RTD resistance at room temperature (compare to probe resistance chart). If resistance does not match the chart, replace the RTD sensor probe.
Determine first 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 first 15 seconds if the fan is turning (should feel air flowing 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.
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.

Verify there is nothing blocking the air flow of the fan (that could make the fan turn faster).
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.
DLB L2
out (P2)
Bake
Inspect the cooling fan. Does it appear to be turning normally (air flow, noise)? Verify the fan blade is well assembled.
Check the 120VAC voltage on the fan. A voltage higher than 120VAC + 10% could make it go too fast.
On Relay Board
Bake (P10)
Verify wiring between P2 on the display board and P2 on the oven lights control board.
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.
Open circuit/infinite resistance
ELEMENTS
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).
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.
If the above steps failed to solve the problem, replace the ESEC UIB board.
If problem persists replace the oven controller.
If the problem persists, replace the display board.

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.
