Question about Refrigerators
I need to refill my compressor with r12 but want to make sure I add to low pressure side. How can I tell?
R-12 hasnt been used since 1994 and if you are sure, by looking on the model number tag, that yours does have r-12, then you need to find out where it is leaking out from. freon doesnt get weak, it will just leak from usually a corroded copper line.
the small line on your compressor is the "high" side and the larger line is the "low" side.
also r-12 is hard to find now but if you can get some then you might be able to buy some time until the freon leaks out again. i wouldnt plan on this unit working for much longer, but you might get by for awhile.
check the "heat exchanger" for signs of oil or corrosion. thats the most common place to find a leak. the heat exchanger looks like it has a small copper tube soldered right on to the larger tube, and is usually covered with a foam insulation sleeve.

Usually the cap where you add will only fit the low pressure coupling also the caps covering the add spigots are labeled L and H - Low and High. If there isn't a clear way to go, Google the make and model # and add the search work diagrams and you should find a compressor diagram to help.
