Confirm all input, output, and grounding wiring is present, and that all required components are present and operational. For example, oil that is brown and overheated may indicate the compressor is overheating. Using R-410A, this compressor increases efficiency and performance for medium-temperature applications. Start both compressors, amperage is balanced and within tolerance, both compressors. Improper refrigerant/airflows and heat exchanger cleanliness can cause compressors to run hotter and at higher pressures. Left the compressor unplugged and turned on ac and the condenser fan motor came on and stayed running. Shorts in the windings and the presence of liquid refrigerant in the compressor due to an improperly operating system can ultimately lead to compressor bearing failure, he added. High temperatures break down the motor winding insulation, which may cause a loss of electrical resistance and result in a short to the ground or even an open winding.
