You've got it overcharged if it calls for 29oz and you put in 41. If conditions are right it won't cycle, that's not a good indication that the charge is correct. It's making the noise and spraying the oil/refrigerant mist out the safety pop off valve on the compressor similar to the safety valve on your shop air compressor. Pull out the refrigerant and weigh in the correct amount. New compressor should be fine.



A high pressure switch should cut power to clutch before it hits the safety but not always. Some systems don't have a high pressure cutout either. If you do it could be stuck. Either way it's overcharged, start there.
