Door was opened at beginning of self cleaning sequence.. locking mech is still stuck

Unfortunately, the F91 error indicates that the door lock is not functioning or the signal that the door is locked didn't get to the control unit. The range will not begin the self-clean cycle if there is a chance that you could open the oven door when the oven is dangerously hot.

First try cycling the power by unplugging the range (or turning off the circuit breaker). Next check if the lock has engaged. If the lock doesn't engage, check if the mechanism is bent or binding. Next check the wiring to see there is damage that will prevent the communication between the control board or the door lock. Check for corrosion at the wiring harness connections.

If the error happened after doing a self-clean, I'd suspect the door lock hadn't released. That can be related to a damaged over-temperature sensor or the lock itself. If the range has been self-cleaned before, it's possible that the lock was broken after forcing the door to open after that self-clean cycle.

You may need to replace the lock, the wiring or the control board. Please add a comment with the model of your range for a parts diagram. If your range is under warranty, contact GE.

I hope this helps.

This happens with a lot of ovens. It's because the mechanism that locks the door is stuck. When the door doesn't lock you can't do a self clean. They don't want you to be able to open the door while the oven is 800 degrees? or so. Look just below the little button that gets pushed in when the door is closed, upper left, and you should see a vertical slot. This is where a little lever comes out and grabs the slot on the door. There is a microswitch inside that tells the oven if the lever has come out or not. Your lever is stuck.
You can test this in a totally dangerous way by opening the door, holding in the button, and turning on the self cleaning. If everything is correct you will see the lever come out to grab and lock the door, but your's won't because it's stuck. Jiggle it or push on it or pull on it with needle nosed pliers. It frees up pretty easily. But when it does, the oven will go into self clean, which you don't want it to do with the door open, so turn it off, close the door and try again. It should work fine.

You must allow for the temp to cool down in the oven first. As the temp rises on the oven to a dangerously high level of 900f if anyone were to open that door they would be severely burned.
A thermostatically operated locking mech is installed to lock the door. The only way to get the door open is to wait till the oven cools down. If the mechanism is stuck locked you must remove the oven from the wall and disconnect a rod in the rear to get the oven open.

If the oven is finished with the self cleaning cycle and cooled down, it should automatically unlock the door.If it doesn"t, try unplugging the oven to see if that will reset

Hi,
Cycling the power off and then on again will sometimes reset it...often you will have to call the customer service number to get the steps to take to unlock that...

Either your lock motor switches are defective and out of sequence or your electronic control(clock) is bad.

This is a Door lock malfunction. you will need to replace the door lock mechanism. it is faulty.

Test the door lock mech for its operational value to be sure.if the door mech test is good, replace the control(ERC/Clock)

Open the door. In the upper left corner, press and hold the door switch (the one that controls the inside light). Start a self clean cycle and wait for lock motor to engage. When the lock stops moving it should be in the unlocked position. Press cancel to stop the self clean.

If you need more assistance let me know.
Good luck!

Hi,

The lock motor may have failed. Most often, bending a coat hanger into a hook and sliding from the right side as you move the door to the right,will allow you to release the lock and open the door.
