Lennox 93M14 Crankcase Heater 324846-701 Measure the microamps (µA) byThe Lennox 93M14 Crankcase Heater is a critical component for maintaining compressor health in high voltage commercial HVAC systems. This 480V 40 Watts Crankcase Heater is specifically engineered to prevent refrigerant migration to the compressor oil during the off cycle. By maintaining a constant temperature above the refrigerant saturation point, this heater eliminates the risk of liquid slugging and "foaming" upon startupcommon causes of
