Engine Refrigeration (Supplementary) USCG Question #514 (Set 7)

A refrigeration unit will tend to short cycle when operating under what conditions?

Official USCG Answer & Rule Citation

Correct Answer: Option A — lack of refrigerant

An undercharged system causes rapid pressure fluctuations and low suction cutouts, resulting in short-cycling as the compressor quickly evacuates the remaining limited refrigerant mass from the evaporator.
