Product review (4 stars): Easy to Replace and Fixed the Problem
I had a burner that got hot - but only full hot - it no longer was adjustable.  Information on the web implicated this part.  The Whirlpool parts diagrams available on the web are difficult to interpret and do not clearly tell which switch goes to which burner.  I opened the cooktop to verify the connections and confirm that this switch was the one.  Once it arrived it was easy to replace and fixed the problem.  Nice.
