Description
The Carrier CPCRKHTR004A00 Crankcase Heater is an electric resistance component that warms the compressor case when the unit is idle and is used in HVAC systems. It is fitted around or within the motor housing where it maintains oil temperature and reduces refrigerant migration. it operates at a 240V input and provides continuous low-watt heat to keep condenser oil separated from refrigerant, limiting oil dilution during shutdown periods and cold conditions. It remains energized when power is present, preserving lubrication stability and reducing damage on compressor components during cycles.
