Product review (5 stars): Great Replacement, but You may already have a spare in the other end of the door.
Works great; easy to install, but there was already a spare Door Catch on the inside of the door on the other end of the door of our Kenmore dryer.  Discovered it when I used the one I bought to replace the failed one.

I guess there are two catches in each door because they want to be able to switch it from right or left swing.
