Whirlpool refrigerator #ED5FHGXKQ00. The four wires, (green, white, red, and black) where on the compressor are they suppose to plug in at? I have a white wire from the rely that is not plugged in after the tech. looked at it and there is a green wire along the bottom (not connected to the rely) it is coming from... maybe the power cord and is not connected anywhere. I've already paid this tech. to replace the rely 2 months ago and now he says the compressor needs replaced. Am I being mislead? Can I fix this on my own?
