Product review (5 stars): Works and at a MUCH better price than you'll find at a parts store.
I have an older dryer than no longer buzzes and stops when clothes are dry.  Whenever we forget and leave it running more than an hour, it blows a fuse.  That used to mean a trip across town to a parts store and $25.....  Now I just keep a few of these on hand.  It's still annoying, but not near as big a deal.
