Which of the following conditions would indicate that the liquid line strainer in a refrigeration system has become excessively restricted and requires cleaning or replacement?

🔍 Key Concepts

• Liquid line between condenser/receiver and expansion device • Effect of a restriction in the liquid line on pressure, temperature, and refrigerant flow • Normal locations where frosting is expected in a healthy system

💭 Think About

• If flow through the liquid line is restricted, what happens to the pressure and saturation temperature on the upstream and downstream sides of that restriction? • Where in a refrigeration system would you normally expect to see frost when the system is operating correctly? • Which of the listed symptoms clearly points to a pressure/temperature change across the strainer itself, rather than somewhere else in the system?

✅ Before You Answer

• Identify which options describe a condition that occurs directly at or across the strainer location, not at distant components. • Consider whether high suction pressure is consistent with a starved evaporator caused by a liquid line restriction. • Ask: does frosting at the receiver outlet or compressor inlet necessarily mean the strainer (specifically) is restricted, or could those be caused by other faults?
