What is the corrective action for an ei f9 error?

So F9 would explain why your door latch isn't unlocking since F9 means your door latch has failed to move. Ok so it sounds like your door latch may have failed.

again.

From what you have described your Frigidaire oven lock is stuck open and you are receiving error codes "F9" and "DR". The "F9" error code stands for runaway temperature (overheating). This could be an issue with your RTD (Resistance Temperature Detector) or the EOC (Electronic Oven Control). I would recommend performing a reset on your oven and you can do that by disconnecting from your oven for ten minutes. The "DR" code means that the door is not closed or the door latch is not recognizing the door is closed. This could be an issue with your door latch or control panel. If the reset does not help correct your issues I would recommend having a professional technician out to perform a proper diagnosis and repair.
From the Manufacturer

F09 - Overflow condition
If the overflow contact on the pressure switch is closed for more than 60 seconds and overflow condition will occur. In an overflow condition, the door will remain locked, and the drain pump will run constantly, even if PAUSE/CANCEL is pressed twice and the Display is cleared. Unplug the unit to service.

Check the drain hose and make sure it is not plugged or inked.
Check Wire Harness connectors to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
Check/Clean Drain Pump Filter of foreign objects.
Check for Drain Pump Failure.
Check the Inlet Valve for proper shut off.
Check the Pressure switch for proper operation.

F9 is a door latch problem. its saying it can not read or detect if door is open. repair latch. good-day ! Unlock door and inspect the switches or clock assembly.

Here's the info from the service manual

"Fault Code: F9

Likely Failure Condition/Cause:
1. Door motor failure / jammed. Latch
motor switch failure.
2. Control software failure, or component
failure (relay stuck).
3. Wiring Problem.

Suggested Corrective Action:
1. Press CLEAR key.
2. If CLEAR key does not eliminate problem, turn off power for
30 seconds, then turn on power.
3. Check wiring of Lock Motor, and Lock Switch A and Door
Switch circuits.
4. Unplug P4, apply power (L1) directly to the Lock Motor, if the
motor does not rotate, replace Lock Motor Assembly. Plug
P4.
5. Check Lock Switch A 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 control."

Hi
F9 error in your unit indicates a problem with the door lock circuit, let the oven cool down and then try opening the door. You can also insert a screw driver to press the latch and then open the door, after it is open inspect for a broken/burned wire between the control and the door lock circuit. If everything seems fine and issue returns then the door lock assembly should be replaced. Hope this helps....
