Which risk increases when a refrigeration system loses refrigerant?

A)Compressor motor winding overheating
B)Expansion valve capillary tube blockage
C)Evaporator coil fin shattering
D)Condenser coil tube weld cracking

💡 Explanation

Compressor overheating increases because mass flow is reduced. The refrigerant absorbs heat, and without adequate flow, the motor will overheat due to reduced heat removal. Thermal runaway is therefore more likely, rather than physical damage, given lubricant interactions.
