Service diagnostic found that air handler would run and call for cooling. I checked over the condenser unit and found that rodents had chewed through the wires to the low and high-pressure switches. The wiring harness for the compressor was still in good condition. Options for repair were presented to the homeowner, and He chose to have the wiring repaired. I removed the old and damaged wires and ran new wires to the pressure switches. I function tested the system and the system is now operational. The system was running at the completion of service.
