Product review (2 stars): Not as pictured, mounting holes too small.
Received a knock-off of the Whirlpool defrost timer kit #482493 . No instructions, no hardware, and mounting holes too small. Jumper was already configured to pin #1 (which was correct for my model after an internet search for the instructions) but I had to drill the holes to the proper size to fit the plastic pins in the frig. Working for now but a real pain. The genuine Whirlpool FSP replacement kit includes mounting hardware and installation instructions.
