Product review (5 stars): This one kit is for 4 types of compressors.
I have a Whirlpool Conquest fridge that is about 10 years old.  The fridge made a clicking sound every 20 seconds or so and the fridge did not automatically shut off.  This is because the compressor did not turn on to cool the fridge.  After doing some research, the problem was a bad compressor relay.  This relay is plugged on the compressor with 3 or 4 wires connected to it.  After removing and inspecting the relay,  the part smelled like burnt ceramic.

This kit has relays for different compressors.  At first, I was confused because my bad relay did not look anything like in the picture and was hesitant on ordering this kit.  Installing the new relay is simple.  The instructions included will tell you which relay to use.  To find the model of your compressor, there is a sticker, near the relay, with the model number on the compressor.

I have used the small black, one of the small white, one wire and the black cover.  Anybody who has bought this kit and has those parts left over,  please let me know.  I am assuming we both have parts that we don't need and I'm willing to do a trade so it will both save us time and money if this relay goes bad again in the future.
