Which risk increases when a refrigerator cycle's cooling efficiency degrades?

💡 Explanation

Compressor run-time increases to maintain cold temperatures. Joule heating in windings increases because electrical energy converts to heat, therefore stator risk of overheat increases, rather than altered function of the expansion valve/ evaporator coil downstream.
