Product review (5 stars): Didn't need to be replaced after all!
Our Kenmore front load washer stopped working. It gave us an error code "F DL". The book said to replace the door lock switch. I ordered one and today I put it in. It was a very easy install - Unplug the machine, accept help from a three year old and a six year old (child labor optional),remove the spring strap from around the front seal, remove three screws holding the switch assembly in place, unplug three wire harnesses on the switch assembly, and replace the switch assemble. It only took about five or ten minutes.

After it was all back together it still didn't work. Then I noticed the latch (the part that is attached to the door) was loose and could slide left and right. I messed with it for a bit, centered it, tightened the screws holding it in place, shut the door and wonder of wonders the machine worked! The original switch wasn't the problem at all! Try this before you order a part just to be safe. Oh, and don't worry about the part; I'm keeping it. I figure it was my own mistake for not looking the machine over better in the first place and there's no reason to return the part, making the seller eat their labor and have to restock it, just because I goofed.
