This heater wraps around the crankcase of a refrigerant compressor and applies gentle, continuous heat to prevent refrigerant migration into the compressor oil during off cycles. Refrigerant migration is a leading cause of compressor failure, particularly in systems that experience long idle periods or cold ambient conditions. By keeping the crankcase warm, this band heater helps protect the compressor from liquid slugging and oil dilution at startup.\u003c\/p\u003e\u003cp\u003eRated at 40 watts and 240 volts, this crankcase heater is built for standard residential and light commercial HVAC equipment. It fits compressors with a circumference range of 18.7 to 21.9 inches, making it compatible with a wide range of scroll, reciprocating, and rotary compressor housings found in split system air conditioners and heat pumps. HVAC technicians and refrigeration service professionals rely on crankcase heaters as a routine component in preventive maintenance and system repair work. Proper installation ensures the heater maintains consistent contact with the compressor shell for efficient heat transfer.\u003c\/p\u003e\u003cp\u003eThe SOURCE1 2541000000 is an OEM-quality replacement part sourced through the SOURCE1 brand, which supplies genuine and compatible components for York, Luxaire, Coleman, and other Johnson Controls family equipment. Using the correct crankcase heater for the specified circumference range ensures reliable fit and safe operation. This part is a practical solution for field techs replacing failed or missing crankcase heaters on existing systems or commissioning new equipment in cold climates.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e40-watt, 240-volt crankcase band heater for HVAC compressor protection\u003c\/li\u003e\n\u003cli\u003eFits compressor circumferences from 18.7 to 21.9 inches for broad compatibility\u003c\/li\u003e\n\u003cli\u003ePrevents refrigerant migration and oil dilution during compressor off cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe SOURCE1 2541000000 crankcase band heater delivers reliable compressor protection at 40W and 240V, fitting a circumference range of 18.7 to 21.9 inches.
