A symptom of a restriction in the liquid line is indicated by which of the following?

A restriction in the liquid line of a refrigeration system affects the refrigerant's ability to flow smoothly, leading to various symptoms throughout the system. When there is a restriction, the amount of refrigerant that can flow into the evaporator is limited, which can cause changes in pressure readings.

Choosing the high side saturation temperature being low indicates that the refrigerant is not condensing properly due to the restriction. This altered pressure and temperature relationship affects the high side of the refrigerant cycle, where the refrigerant is supposed to be in a high-pressure state after being condensed. A low high side saturation temperature suggests that the system is not efficiently removing heat from the refrigerant, leading to inadequate cooling performance. In this scenario, the restriction hampers refrigerant flow, which impacts the overall heat exchange process.

The other options reflect different conditions not directly indicative of a liquid line restriction. Low low side pressure suggests a different operational issue, likely related to refrigerant level or evaporator efficiency, while normal amp draw may indicate that the compressor is operating within its expected parameters, and a high low side saturation temperature typically indicates an issue with the evaporator or a maldistribution of refrigerant. Thus, recognizing the low high side saturation temperature is crucial for diagnosing a restriction in
