Carrier HT32BH850 Crankcase Heater R-410A Field adjustments are not recommendedThe Carrier HT32BH850 Crankcase Heater is a critical OEM replacement part designed to maintain optimal oil viscosity in high capacity HVAC compressors. Specifically engineered for 480V systems, this 70W resistive bellyband heater prevents refrigerant migration to the crankcase during the off cycle, mitigating the risk of slugging and bearing washout at startup. Its low profile, wrap around design ensures maximum heat transfer to the compressor shell,
