Which consequence results when a hermetic compressor motor overheats due to refrigerant leak?

💡 Explanation

When a refrigerant leak occurs, the motor overheats because the refrigerant no longer effectively cools it, leading to breakdown of the motor windings' varnish insulation which releases contaminants into the system. Therefore varnish breakdown results, rather than increased compression, oil thickening or decreased superheat, which occur for different reasons.
