The door is locked and will not open display says door locked been that way 3 days

There should not be a childproof lock on your microwave.
However, it is remotely possible that there is electrical failure preventing the door opening.
Most, not all, microwaves can be taken apart with screws with the door closed.
See if you can do yours.
You should find the latch holding the door is broken or stuck or whatever.
God bless your efforts.

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-

Next time get a car that doesn't have so many electronics on it. The more there is of that, you will always have a problem. Try the fuses. Open the door panel and look at all of the wiring. That's all I have.

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.

Hi from retired Englishman in SW France,

The symbol indicates there is a problem with the door lock. Either the locking solenoid or the door lock sensor is malfunctioning and requires attention. Sorry- Service call!

The ES 200 electronic oven control system is made up
of three parts that control the bake and broil elements,
and the locking of the door in the self-clean cycle.
1. Electronic oven control.
2. Oven temperature sensor.
3. Oven door lock mechanism.

I held down the clear button for three seconds, it unlocked but still showed the lock button lit. It began beeping over and over. I opened the door and pressed the clear button again for three seconds. It stopped and the oven works just fine now. In fact, I used it right after I got it cleared out.
