SOURCE1 2541000000 Crankcase Band Heater 40W 240V 18.7 to 21.9 Inch Circumference

Product Description

The SOURCE1 2541000000 is a crankcase band heater designed for use in HVAC compressor applications where moisture control and oil viscosity management are critical. 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.

Rated 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.

The 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.
