Description
The Carrier P041-4443 is a belt-type crankcase heater engineered to protect compressors from refrigerant migration and oil dilution during off-cycle periods. By maintaining the compressor crankcase at an elevated temperature, this heater helps prevent liquid refrigerant from accumulating in the oil, reducing the risk of compressor damage on startup and extending overall system service life.
Key Features

Why Use a Crankcase Heater?
Crankcase heaters are a critical component in refrigeration and air conditioning systems, especially in climates where equipment sits idle for extended periods. Without a crankcase heater, refrigerant can migrate into the compressor oil during the off cycle, causing oil foaming and slugging at startup — a leading cause of compressor failure. The Carrier P041-4443 provides continuous, low-wattage warmth to keep the oil free of refrigerant contamination and your system running at peak reliability.
