If a refrigeration system, equipped with a reciprocating compressor, has a liquid line solenoid valve that is leaking during the 'off' cycle, what would this cause?

Correct Answer: Option D — noisy compressor operation upon starting

A leaking liquid line solenoid during the off-cycle allows refrigerant to slowly bleed into the evaporator and drain into the compressor crankcase. Upon startup, this accumulated liquid flashes and causes severe hydraulic shock, manifesting as loud compressor noise.
