Thank you for your question and I understand your concern.
Try pushing inwards and holding slight pressure on the upper middle section of the door while programming and starting a Clean cycle. Wait one minute and then press Stop/Clear while still pushing inwards on the door and then wait to see if it will unlock. If it will not unlock then you will likely need to call a service technician to diagnose and repair your range.
The only other way to unlock the door whenever there a component failure is to un-install the range and remove the rear panel. The door locking mechanism/motor is located as shown in the image below.
NOTE: Disconnect the range from the power source before servicing your range.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
