Product review (5 stars): Too bad the pictures were not in color but rather black ...
My Jenn Air refrigerator model JCD2389GES starting to make an intermittent clicking sound and then noticed both the refrigerator and freezer were not cooling and had to discard a ton of spoiled foot.  Rather than call the appliance repair people I decided to try and fix myself.  Doing some research on YouTube the symptoms called for replacing the start relay for the compressor.  Doing more research I noticed there was not a direct replacement that looked identical to the original part, but this kit which fit many Whirlpool, Amana and Jenn Air refrigerators.  I paid the extra expedited shipping to get the parts in a couple of days and when it arrived the directions were very straight forward with some pictures of the wire connections to the compressor.  Too bad the pictures were not in color but rather black and white making it a bit tougher to determine the wiring sequence.  Overall, it was a pretty simple install taking no more than about 10 minutes to replace both the start and overload relays and connect the three wires.  Just some basic tools were required to complete the repair, and of course always disconnect the electric plug from the wall outlet before starting.  Once installed the refrigerator compressor fired right up and is running normal.
