Product review (5 stars): Had to watch a video for it to make sense, then the light bulb came on.
Just replaced this part on a Kenmore side by side.  At first I thought I that there was a mess up on the packaging.  The instruction kept refuring to 2 different relays, well after watching a video, I realized that there are 3 relays in this kit, watch this video and it will help you if you are confused.  http://www.youtube.com/watch?v=LJqBZeJXVss  "Refrigerator Compressor Starting Device Kit (part #8201786)-How To Replace"

Also the packaging said whirlpool on it so I assume this was made by whirlpool.
