Which mechanical outcome occurs inside a refrigeration system when the condensing temperature increases significantly,?

A)Compressor overheating from high discharge pressure
B)Evaporator frost buildup decreasing efficiency
C)Expansion valve corrosion accelerating refrigerant leaks
D)Condenser coil cracks due to thermal stress

💡 Explanation

When condensing temperature rises, compression ratio increases because the compressor must work harder to achieve required high-side pressure causing excess motor current leading to overheating. Therefore, compressor overheating results, rather than frost, valve corrosion, or coil stress, which depend on other faults.
