Which failure mode occurs when a refrigerant leak exposes a hermetic compressor motor windings to excessive moisture?

💡 Explanation

When moisture enters the system through a refrigerant leak, hydrolysis occurs resulting in the formation of acids within compressor oil which corrodes the motor windings causing short-circuits. Therefore, acid formation and corrosion results, rather than cracking capacitors, decreasing volumetric efficiency, or blockage which require other mechanisms.
