Product review (4 stars): Plug it in and it WORKS!
We've been without the second side of our stovetop for years.  I'm so glad we came across this item for our Whirlpool stovetop. The whirlpool parts are discontinued, but this Jenn-Air part works with our range.

Only reason this is 4 stars and not 5 is because we ordered the black, but the cartridge is actually silver, so it doesn't match.  We were so desperate for a full stovetop that were keeping it!
