Product review (5 stars): Fixed the issue
Our cloths were damp after a drying cycle completed.  When started, it would heat up, but at the end of the cycle the dryer was cold.  Found a troubleshooting video on YouTube and the symptoms pointed to the coil going bad.  Call the local Sears part - Sears dryer - and no answer.  Online was over $20.  Amazon had the Whirlpool coils with same day delivery free with a $35 order.. Too easy, I needed some other items anyway.

Took about a minute to install.  Word of caution from the video I watched, the coil with three connectors has a metal sleeve on its post.  Make sure it stays with the post.  Mine did, but it was a good check to make sure the valve will function.
