Carrier HT32CH764 Crankcase Heater 32W 120V

The Carrier HT32CH764 is a part called the crankcase heater for Carrier HVAC equipment and is most likely, but not definitely, for outside condenser units. This elongated and slender heater has the crucial function of avoiding problems with the viscosity of oil in cold temperatures. In cold climates, the oil within the crankcase tends to become thicker and thus it’s difficult for the compressor to start. By pre-heating the crankcase oil, it makes it easy for the compressor to start up, and work efficiently during cold climates to avoid hard starts or failure. The right oil viscosity at startup reduces friction and wear of the compressor parts, which can lengthen your AC unit.
