Removed old equipment and installed new Trane 3 ton 454b heat pump and air handler. When testing system operations the condenser fan would run but the compressor would not start. Checked all wiring connections, checked for high voltage, checked continuity on compressors terminals and plug wires. Tested amp draw on compressor and compressor is pulling 45amps but not running. Will need to send a technician out with a hard start kit and a new 45mfd + 5mfd capacitor to test it to see if the compressor will kick start.
