Unplug your refrigerator and move it away from the wall. Notice the panel covering the bottom of the rear of the refrigerator. This covers the compressor.
Remove all screws on the sides and corners of the rear panel of your refrigerator.
Lift the panel up and set it aside. You will now have access to the compressor. It is the football-sized assembly next to the fan.
Replace the rear panel and replace the screws when finished.
