Which outcome occurs when desiccant filter drier saturates in an HVAC refrigerant loop?

💡 Explanation

When a desiccant filter drier saturates, its water absorption ceases, leading to moisture circulating in the refrigerant loop, which undergoes expansion/cooling within the capillary tube, causing ice formation and subsequent blockage. Therefore capillary tube ice blockage results, not motor breakdown, valve failure, or fin corrosion which involve different failure mechanisms.
