Remove the access panel on the back of the refrigerator. This panel is located at the bottom. The compressor sits in the bottom of your refrigerator because of its weight. Unscrew the screws in the panel using a screwdriver. Remove the panel and set it aside along with the screws you removed.
Locate the compressor and the mounts. You will see a retaining clip on top of one of the mounts. This secures the metal tongue that extends from the compressor to the mount. Remove the retaining clip from one mount. You will need either a screwdriver or a pair of pliers to remove the clip.
Lift the compressor. You must use a crowbar. Wedge the crowbar under the compressor and lift upward. This will take some of the weight off the mount you are working on. You will not be able to lift the compressor completely off the mount because it will still be connected to the other mounts. All you need to achieve is taking some of the pressure off the mount that you're working on.
Slip the old mount out. Slide a new one in its place. Make sure that the metal tongue that extends from the compressor rests on mount properly. Replace the retaining clip to secure the metal tongue to the mount.
Repeat the procedure for all of the mounts. You will find a total of four mounts.
Replace the access panel and plug in the refrigerator. Listen for noise and feel the side of the refrigerator for vibrations. If you find any problems, check the retaining clips to make sure the compressor is properly secured to all four mounts.
