Product review (5 stars): Money saver!
My Kenmore 80 series stopped working.  It would turn on but it would stop heating after about 10 seconds and wouldn't heat again, it would just spin.  After reading several websites and watching some youtube videos, I was able to guess that the problem was the Gas Valve Coils.  8 bucks and 8 minutes later, my dryer is working as good as new!
