Product review (5 stars): Easy fix for Whirlpool Dryer.
I knew the dryer door switch was going bad, because the last couple of months the dryer stayed running whether the dryer door was open or closed.  Then one day the dryer would not run at all.  The part and number was easy to find on the Whirlpool website.  I first called the Whirlpool parts vendor and they wanted $31 (shipped) for the same part.  I found the exact same switch for $11 (shipped) from this seller on Amazon.  The install was easy and took me 15-minutes from start to finish.  Check YouTube for a repair video for this switch.  Love Amazon.com.
