Arrived at house and was told condenser unit wouldnâ€™t turn on. I checked incoming voltage and had no power. I go to breaker panel and the ac unit breaker was tripped. Every time I switched breaker to on position the breaker would trip. I then took off compressor windings off contactor and herm winding and fan motor only turned on. I checked continuity and the leg on compressor is faulty. Charging for diagnostic only today. I clarified problem to owner and is aware of issue.
