Removed single screw at bottom left of door holding door in place. Removed door. Removed all self tapping screws holding trim plate to oven frame. Trim plate is still attached to the rest of the oven. After removing trim plate screws gently moved plate and oven about 1/2" or more forward. Was then able to see rear washer which was still behind trim plate. This washer is kinda oval/square and has threads in it. The plastic strike is threaded and screws into the washer that remains behind the trim plate. There are 3 other washers which fit in front and behind the trim plate over the plastic strike. There was enough thread on the strike to re screw it to the back washer. After doing this replaced the self tapping screws in the trim plate and replaced the door and its attaching screws and washers. I can't believe that the strike and washers are being sold for over $20 and some sites almost $30.
Always see what needs to be done before wasting $ for parts you do not have to replace.
