Stove kept locking either door or oven controls. Removed back of stove and discovered a the rod from the controller to the door lock on the front top inside oven door. Apparently had a burr on it, therefore grabbed the insulation and rolled it around the rod making a 1-1/2" cocoon on the rod. Cut it off smoothed down the insulation protruding from the 4" hole in the top plate "protecting" the insulation. it works fine after a year of problems . With no Service call or outside repairs. Somedays are a joy!!!!
