Product review (5 stars): Yippee! Just fixed my dryer in 5 minutes for $7!!!
I have a Kenmore model 110.64832400.  The drum has continued to spin with the door open for the past 6 months or so.  I didn't think much of it, but we just got back from vacation with mountains of dirty laundry and suddenly nothing happened when I pushed the button to start the dryer.  After flipping breakers to no avail, I watched an appliance trouble shooting video I found online (http://www.partselect.com/Repair/Dryer/Will-Not-Start/).  Figuring the door switch was the likely culprit, I opened the dryer and removed the old switch (2 screws).  The black switch lever was obviously broken as it swung freely.  I then found this switch which looked the same and had the same model number, even though it said it was for a Whirlpool.  Our local appliance store wanted $24 for the same thing, so for $7 I figured it was worth the risk.

The switch just arrived at the mailbox (ordered Sat. arrived Thurs., free shipping).  In literally 5 minutes I had installed the new switch and voila! the dryer works perfectly!  I am doing a load as I type.  Couldn't be happier.  Ps: I am a 52 year old mom/grandma, if I can do this, anyone can.
