Product review (5 stars): Fast delivery and exact replacements
Very prompt delivery and exactly the same parts as those that had to be replaced.  No instructions were included, but there are numerous videos on YouTube that show in detail how to check the four things that could be wrong with the dryer (electric) not heating.  Both parts provided should always be replaced at the same time whether or not both are bad.  Coincidentally (or not), both were bad.

The problem is easy to diagnose if you have a digital multimeter (which every handyman should have), and repairs require a minimum of tools.  Repair is easy, though some of the screws may be difficult to access.  However, you can get to them with a 1/4" bit (without the driver), and a crescent wrench to turn the bit.
