In this video, I demonstrate how I repaired a mini fridge that had its refrigerant leak out by adding more R134a refrigerant. Before attempting this project, check your owner's manual and other diagnostic information to make sure you actually have a refrigerant problem and not something else. Also, once you have a leak, you will likely need to top up the refrigerant regularly until you replace the refrigerator.
