Tip & How-To about Refrigerators
You don't need brazing skill or brazing tools to add freon to a refrigerator. And you don't need license to buy it's freon because all refrigerators now a days use R134.
First you will need a line tap which is available at most ac supply. Then you will need a retro fit adapter. available at most auto parts or where they sell automotive ac accessories. Then the freon and charging hose for R134. You would do it as if you are charging an old car with R134. Note that you should use the charging hose with the gauge. If you are handy it is a piece of cake.
One thing to remember is that refrigerators are not air conditions. So the low side pressure is much lower. As you charge it the pressure usually starts at 10psi or less then as the freezer gets colder can be as low as 5psi. Another thing is that it uses much less freon. An indication that it is overcharged is the compressor gets cold instead of getting warm. An indication that it is low on charge is that the compressor gets too hot, and the coils (condenser) do not get warm enough to dissipate heat.
