Why is compresser frozen?

Answer 1

When A compressor locks up on a car 99% of the time it is due to the compressor becoming worn out. When a compressor starts to wear small fragments of metal and rubber are pumped through the system. These fragments eventually make their way back into the compressor and jam it up destroying the compressor. This contaminates the entire system usually and will require a qualified, licensed technician to repair correctly. The system will have to be evacuated and all refrigerant recovered. The compressor, accumulator, and orifice will all have to be replaced in order to have a warranty. The entire system will have to be flushed. Next reassemble the system. Then a vacuum must be applied to remove any and all moisture in the system any moisture in the system will freeze and cause poor performance. Then finally the system must be recharged with the correct refrigerant and the exact capacity in weight, too much or too little will again cause poor performance even if its only one or two ounces with some systems.
