Which consequence results when an obstruction occurs within a refrigeration system evaporator?

💡 Explanation

Reduced cooling capacity occurs because the expansion valve regulates refrigerant flow; an evaporator blockage increases pressure drop, starving the remaining evaporator tubes via flow distribution rather than a restricted expansion valve passage. Therefore, reduced heat absorption occurs rather than ice, or motor issues.
