Q

The low pressure cutout switch will cause the compressor in a refrigeration system to short cycle under what condition?

🔍 Key Concepts

• Low pressure cutout switch function in a refrigeration system • Meaning of short cycling (frequent starting and stopping of the compressor) • How differential pressure (cut‑in vs cutout) affects compressor operation

💭 Think About

• Think about which option would make the suction (low side) pressure repeatedly drop below and then rise above the low‑pressure switch setting in a short time. • Ask yourself: which condition directly affects the control settings of the low‑pressure switch, instead of just changing system load or blocking refrigerant flow? • Consider what would cause the compressor to stop on low pressure, then quickly restart, over and over again rather than stay off or stay on steadily.

✅ Before You Answer

• Identify which choice talks about the relationship between cut‑in and cutout pressures, not just a mechanical fault elsewhere. • Decide which condition would cause the low side pressure to hover near the switch setting, making it trip frequently. • Eliminate options that would more likely cause the compressor to stay off for a long time or not build normal pressure, instead of rapid on‑off cycling.
