Thomas S Newport News , VA December 29, 2015 Appliance: Model JSP42B0K5BB Range door would not lock so could not self clean I purchased and replaced the door lock mechanism. It took some YouTube research and trial and error to disassemble the oven controls to get to the mechanism, but once replaced and reassembled, all worked well.
