SOMTIMES you can overcharge the system, if you were charging it. What happens is the (belive it is called the high pressure relay...or whatever), a safety relay will stop the singal to the compressor to turn it on. If you don't have a pressure gauge, and you think it's over-cgarged, just let a little out at a time until the compressor kicks in. It is a fairly common problem...
did not charge it just quit so then i charged it did not help
