Product review (5 stars): but glad I decided to test it first by bypassing this ...
None of the burners would light when we bought our house.  There was gas but no spark or "click".  I almost bought a new igniter, but glad I decided to test it first by bypassing this harness.. The igniter fired just fine so that meant all 5 switches on the original harness had failed.

The whole job of getting to the igniter and later replacing the harness was kind of a pain.  Once I got it back together, one of the burners wouldn't spark, even though it was clicking (harness isn't at fault).  Luckily it's the back center one which would be the least-used anyway.  Saved myself at least $150 by doing it myself and was able to give it a thorough cleaning.
