← TechnologyWhich outcome occurs after sustained operation of automotive AC with refrigerant overcharge?
A)Compressor damage from liquid slugging✓
B)Expansion valve failure due to blockage
C)Condenser corrosion from acid formation
D)Evaporator freezing causes airflow reduction
💡 Explanation
When refrigerant is overcharged, liquid floods the compressor because there isn't sufficient superheat allowing liquid into parts built for gas, leading to liquid slugging and mechanical stress. Therefore, compressor damage results, rather than valve blockage, condenser corrosion, or evaporator freezing which need alternate causes.
