F-90 error - self-cleaning ovn door will not lck and now light flashing and cannot use oven

The F90 error code indicates that the door unlock time exceeded. This will happen if the lock is in the locked position with the oven door open or if the lock motor fails. Have someone hold in the oven door light switch while you set the control up for the self-cleaning cycle. Let the self-cleaning cycle run for only 4-5 minutes then press stop/cancel. This should allow the lock assembly to reset & retract the door lock back into the unlocked position.

You can also try resetting the appliance by disconnecting it from the outlet or switch off the circuit breaker for 20-30 minutes. Once power is restored run a test cycle. If this does not work I suspect a door lock assembly failure. This type of diagnosing will require accessing the lock assembly & using a volt/ohm meter for testing

see to it the there was no stuck object or parts on the door parts...

Hi Beverly,

I understand that you are looking to run your self-clean feature on your Frigidaire range, model# CFEF366EMB.

-To start this you will remove all racks and make sure that any excessive spillovers are cleaned up as best as you can.
-Next you will press the "Clean" button, and the display will show "---".
-Press the up or down arrows to select the length of time you want the oven to clean. Usually 2 or 3 hours.
-The door will automatically lock once your time has been chosen and the "LOCK" indicator light will flash. DO NOT open the door while the light is flashing. (it takes about 15 seconds for the oven door to lock).
-"Cln" will appear in the display during the self-clean cycle and the "LOCK" light will continue to glow until the self-cleaning cycle is complete or cancelled and the oven has cooled.

When the self-clean cycle has completed:
-The time of day or "END" will appear in the display window and the "Clean" and "LOCK" light will continue to glow.
-Once the oven has cooled down for about 1 HOUR and the "LOCK" light has gone out, the oven door can be opened.
-If "END" is in the display and the Clean indicator light remains ON, press the "CLEAR/OFF" button and the time of day will appear on the display.
-When the oven is cool, wipe away any residue or powdered ash with a damp cloth or paper towel.

-Best Regards-

more than likely the tco thermal cutout fuse has opened during cleaning and now the ovens latch motor cant get power to open,its under the top cover where the surface elements are located its a frequent thing with all ovens/stoves

Hello - Before using the self-cleaning cycle of the appliance, remove the broiler pan and any utensils stored in the appliance. Also remove any excess spillovers in the oven cavity. Allow the oven to cool before cleaning. During the self-cleaning cycle, the outside of the wall oven can become very hot to the touch.

Typically to set the controls for a self-clean the first step is to confirm that the clock shows the correct time of the day. Press CLEAN. "---" appears in the display. Press the UP ARROW or DOWN ARROW once. "3:00" appears in the display for a 3 hour cycle. To change to a 2 hour cycle press DOWN ARROW"2:00" appears in the display. As soon as the controls are set, the motor drive lock will begin to close automatically and the "LOCK" indicator light will flash. DO NOT open the oven door while the light is flashing (it takes about 15 seconds for the over door to lock). "CLn" will appear in the display during the Self-Clean cycle and the "LOCK" light will glow until the Self-Cleaning cycle is complete or cancelled and the oven temperature has cooled.

When the Self-Clean cycle has completed, the time of the day or "End" will appear in the display window and the "Clean" and "LOCK" light will continue to glow. Once the over has cooled down for about 1 HOUR and the "LOCK" light has gone out, the oven door can be opened. If "End" is the display and the Clean indicator light remains ON, press CLEAR/OFF. The time of the day will appear in the display.

If it becomes necessary to stop or interrupt a Self-Cleaning cycle, press CLEAR/OFF. Once the oven has cooled down for about 1 HOUR and the "LOCK" light has gone out, the oven door can be opened. Restart the Self-Clean cycle once all conditions have been corrected.

Self Cleaning Oven Problem

" Wish I had read this first. I never would have used the self cleaningoption. Thanks for the info!!

For some reason the oven thinks you have a door that is not shut all of the way. Check the locking slot to make sure that there are no obstructions. Make sure that you are only doing one oven at a time, and not trying to cook in the other. Make sure you have no racks in the oven. Try pushing lightly on the door when the lock engages. For some reason your lock isn't engaging fully and that's why door is flashing. Good Luck
Below is from the owners manual for your oven.

Oven does not self-clean Door not shut tight Check for obstructions. Close door tightly
Oven set for delay timed cleaning Oven will start to self-clean at preset time.
Press CANCEL/SECURE to return to
normal operation
Double ovens only: Other oven is on. Turn off other oven.
