Which outcome occurs when moisture enters a refrigeration system's sealed capillary tube?

💡 Explanation

When moisture enters the refrigeration system's metering device, ice crystals form because the refrigerant expands and rapidly cools, restricting the flow through the narrow tube. Therefore ice blockage results, rather than oil breakdown, overcharge or corrosion, which need different contaminants or thermodynamic conditions respectively.
