Thank you for your question.
I am sorry you are having problems with your range.
Try disconnecting power from the range by turning off the circuit breakers for 60 seconds and returning power. The door may unlock
Set the clock for the time of day, then try putting the oven into a short clean cycle. Only for about 30 seconds, then cancel the clean cycle. The door may unlock.
If this does not solve the locked door issue, we will have to remove front control panel on the range to release the latch hook on the lock motor. The lock motor assembly will have to be replaced.
If you decide to do this procedure please
to the range.
I have included pictures to illustrate this procedure.
First remove the knobs on the range, then remove the nuts that hold the switches to the glass panel.
As described in the picture remove the screws that hold the control panel to the range.
You should now be able to access the lock assembly and remove the screws that secure the motor to the chassis of the range to unlock the door. You can replace the lock motor if you have one at this time keeping in mind the locations of the wires to re-install on the new lock motor. Part number 318261221.
