compressoer went out

Hello

Each unit has a tag with the number of ounces of refrigerant the unit takes along with the refrigerant type. Did you check the tag on the unit to verify you were adding the proper refrigerant type R12, R134A ? Are you weighing in the refrigerant with a refrigerant scale ? If the unit is overcharged and you flood the system it will overheat the compressor and shut the unit off on a overload safety device . Or you could just have a compressor locking up. You would need to check the compressor amprege to see if it is locked rotor amprege. Matt Ace technician
