Product review (2 stars): Not genuine Whirlpool part, and more work to install.
Not a genuine whirlpool part.  The mounting holes shown in the pictures are not there, and the bulb for the thermostat was very short and wouldn't reach where the original did.  I had to drill new holes in this thermostat, then drill new holes to match the thermostat in the existing bracket.  What a PITA.  Turned a 10 minute job into almost an hour by the time you take it to your shop, get out the drill bits that you need, figure out how to mount it, etc.  There's a reason it's cheaper.....
