Things You'll Need
Refrigerant oil (optional)
Home appliances lose their power in time. Fortunately, most refrigerators can be revitalized with a few simple tools and a cylinder of freon. Recharging a refrigerator also is an excellent way to save time and money before replacing it with a new refrigerator. Recharging the appliance also is one way to help protect the environment before depositing the machine in a landfill.

Remove all perishable foods from inside the refrigerator. Unplug the refrigerator and, if possible, move it to the center of the room.
Locate the refrigerator's compressor. This is a cylindrical black component typically found at the bottom of the refrigerator.
Open the compressor's intake valve and attach your vacuum pump to the opened valve.
Vacuum out the remaining freon. It is important to remove any remaining freon so that you do not overfill the compressor and risk leaking freon into the refrigerator or room in which it is kept.
Attach the hose from the freon cylinder to the compressor valve. Tighten the attachment with a wrench before emptying the freon into the compressor. Once emptied, close the compressor's intake valve.
Pour a few tablespoons of refrigerant oil into the hose to eliminate air bubbles. This step is not necessary, but it is recommended.
