Which outcome occurs when a refrigeration system undergoes rapid cycling?

A)Premature compressor motor winding breakdown
B)Increased expansion valve superheat margin
C)Decreased evaporator coil frost accumulation
D)Higher sustained coefficient of performance

💡 Explanation

Rapid cycling stresses the compressor motor windings because frequent starts/stops trigger thermal fatigue; therefore, winding insulation breakdown leads to motor failure rather than improved superheat, reduced frost, or higher coefficient of performance, all of which are affected by steady-state operation.
