Crazy.  With the help of Google and this parts kit I fixed my non functional dryer in about 40 minutes.  My dryer was screeching like crazy when it was running because the belt tensioner had seized to the shaft it was mounted on.  I also found a stuck roller.  A few minutes with simple hand tools and our clothes are dry again....for less than $30.  Thank you!
