Product review (4 stars): I would STRONGLY recommend that any DIY'er really
For me, the product works just as advertised.  HOWEVER, I would STRONGLY recommend that any DIY'er really, really research before making repairs (internet, Youtube, talk to someone you trust who does dryer repairs, etc).  For one thing, there are 2 thermostats in this kit that look very much alike and could be easily confused, and, since one is a high temp "cut off" thermostat and the other is your normal cycling thermostat, replacing one with the other WILL cause your dryer to malfunction.  Also, these parts are meant to be interchangeable with a WIDE variety of  MOST dryer makes, models and production years.  It is possible that your particular dryer could be the exception to the rule and require a different part.  Pay Attention To The Details and Good Luck!
