Which risk increases when a refrigeration cycle bypasses the expansion valve?

A)Compressor bearing overheating due to friction
B)Refrigerant over-compression thermodynamic efficiency loss
C)Evaporator coil icing reduced heat transfer
D)Condenser coil pressure mechanical component failure

💡 Explanation

Bearing overheating risk increases due to the compressed, superheated refrigerant lubricating viscosity reduction; thus, the oil cannot properly lubricate during Increased refrigerant temperatures. This is bearing failure, rather than other refrigeration component malfunction, because of lubricant degradation.
