Product review (5 stars): Easy enough to change DIY
Our dryer switch gave out after a few years of light use.  Thanks to YouTube, good visual tutorials are available from other citizens on how to accomplish this repair.  Throw the breaker to off, drop switch panel, unscrew switch and unplug it from connector and reverse the steps to install the new one.  I am the big hero with my wife for accomplishing this.  Best of all, I avoided what would have been a $150-200 technician charge to do the same work.  I rewarded myself by buying $150-200 of cigars.
