Which outcome occurs when the expansion valve supplying an HVAC evaporator malfunctions and restricts refrigerant flow?

💡 Explanation

When refrigerant flow is restricted, the evaporator receives less liquid, causing the existing refrigerant to evaporate more quickly and completely absorbing heat leading to higher superheat because the vapor heats up beyond its saturation temperature. Therefore superheat increases, rather than flooding, capacitor damage, or icing, which are related to overcharging or different electrical faults.
