Bard part 8605-020 is an OEM wrap-around crankcase heater designed for 460V applications on Bard wall-mounted HVAC equipment, where it helps keep the compressor crankcase warm during off cycles to reduce refrigerant migration into the oil and support reliable cold weather starts. By maintaining proper oil temperature and viscosity, this heater supports long-term compressor protection and steadier system operation in low ambient conditions. For best fit and performance, confirm your unit model and compressor style, since crankcase heater sizing and lead routing can vary by series and vintage, and always follow the Bard service literature for safe installation and wiring.
* Orders less than $50 may incure a minimum order fee.
