Question 1 of 27070

A low compressor discharge pressure for a refrigerator can be caused by which of the following?

🔍 Key Concepts

• Effect of load on the evaporator vs. mechanical condition of the compressor • How compressor valve leakage changes suction and discharge pressures • Difference between heat load problems and mechanical faults in causing low discharge pressure

💭 Think About

• Which option would directly change the compressor’s ability to build up pressure on the discharge side, rather than just making the box warmer? • If discharge pressure is low, is the compressor working against less load, or is it unable to compress effectively? Which choice matches that? • Which options affect primarily the system temperature or heat load, and which affect the mechanical sealing/compression function?

✅ Before You Answer

• Separate the choices into those that mainly increase the refrigerator heat load vs. those that affect compressor internals • Ask: would this condition most likely make pressures HIGH, LOW, or just make the system run longer? • Focus on what would reduce the effective compression ratio by allowing gas to flow back instead of being fully discharged.
