Need Air Condition Help

[GCKIRKLAND]

The compressor worked fine, but the pulley went bad. So I changed the compressor with a new one. Then I took it and had the system vacuumed and charged, but now it cools down to 42 degrees part time. It will work up to 65 degrees then go back down to 42 degrees, also sometimes it will make a vibrating sound for short period then quit, sometimes louder than others. If someone could help it would greatly appreciated.

did you put the proper amount of oil in the compressor before you charged it.

Thanks for the reply, yes poured in 4.5 oz. of PEG 46 oil, then turned the compressor numerous times. I was wondering if this sounds right. I was told that the pressure need to balance out. Seems that the more it runs the better it does.
