Carrier HT36DL481 Crankcase Heater L99H008 While the 18-inch length providesThe Carrier HT36DL481 Crankcase Heater is a critical OEM component designed to protect high pressure compressors in Carrier, Bryant, and Payne HVACR systems. Operating at 460 Volts with a 125 Watt output, this insertion type heater ensures that the compressor oil remains at a higher temperature than the systems coldest point. This specific thermal regulation prevents refrigerant migration and oil dilution, which are leading causes of compressor
