** [Kenmore selfcleaning oven model 665.4493390] When I lock the door and hit the clean button, it displays a message that the door is not closed. **
I agree with Bruno that there may either be a problem with one of the switches of the door latching mechanism (see the following link) or maybe the latch mechanism has gotten bent. Has anyone tried to force the latch or open the door while it was still locked?
