Unplug your GE refrigerator from the wall and pull it out so you can access the rear panels.
Remove the rear bottom panel of your unit by pulling it up and off.
Remove the terminal cover box by pushing in on both ends of the tension spring with your fingers while pulling the cover into the upward position.
Check to see if there is a capacitor. If there is, one of its wires will be connected to the condenser relay switch and another connected to the compressor. Remove the capacitor leads to reduce the risk of electric shock.
Locate the starter relay on the side of the compressor and then unplug it by pulling it out by hand. Use a screwdriver to pry it out if you cannot pull it out by hand.
Plug in the new compressor relay switch and follow the steps backwards to put the back of your GE back together.
