Product review (5 stars): It works.....
One afternoon our trusty Kenmore dryer stopped working.  Being a DIY person (if I can figure it out) did a bit of Googling, you tubing and discovered my "PF" error code was a somewhat common problem.  I went to Amazon to locate the Thermistor that people had recommended as a fix.  For $14 or so I took the leap of faith that this little part was the culprit the replacement would solve my issues.  Saturday rolled around and in a box by my garage held the new part.  Installation took about 7 minutes or so as I had already removed the access panel previously.  I plugged the steed back into the wall hit the button and shazam the dryer was working.  I re-installed the access panel and now our clothes are dry once again.
