Which outcome occurs when a capillary tube becomes clogged within a residential split-system air conditioner using R-410A refrigerant?

💡 Explanation

Excessive ice forms on the evaporator because refrigerant flow decreases from the blockage, employing the Joule-Thomson effect, causing the evaporator temperature to drop below freezing. Therefore, evaporator coil freezes, rather than the system's other processes being mildly impacted if flow was consistent.
