Part for my Whirlpool Refrigerator

I purchased the relay overload kit with cover thinking this was the part that has melted and caused my refrigerator to quit working. However when we received the part today and tried to install it the prongs that connect to the wire are too big. After reviewing the parts list again for my refrigerator I think I should have purchased the compressor starting device kit. The piece I am looking for sits on the side of the compressor. It had a condensor attached to it, but I’m not sure if it’s necessary after reviewing information on your website. Can you tell me which part I need to replace?

Thank you for your help!

The run capacitor MUST be wired in, vital to compressor as it adds running torque.
Did you get part AP3885081?
