Based on customer reports and repair data, this part commonly fixes these issues:
The compressor is a pump which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. If the compressor is not working, the central air system won’t cool properly. However, this isn’t usually the case. Before replacing the compressor, first check all of the more commonly defective components. If all of the other components are working properly, use a multimeter to test the compressor for continuity. If there is an open circuit, the compressor is likely defective. If the compressor is defective, it must be replaced by a licensed technician.
