My refrigerator stopped working. I found that the relay switch that activates the compressor is cripsy fried. I called a local appliance parts store and it looks like I can buy a replacement for the switch. However, I am wondering why it fried in the first place. I want to test the compressor but I don't understand the hookup. Two wires go into the relay, but the relay attaches to the compressor with three terminals. Can I test the compressor by touching the two wires to two of the three terminals? If so, which two? Thanks.
