Why Use a Crankcase Heater?

During extended off cycles — especially in cooler ambient conditions — refrigerant can migrate into the compressor crankcase and mix with the oil. When the compressor restarts, this refrigerant-oil mixture can cause liquid slugging, leading to premature compressor failure. A properly functioning crankcase heater keeps the oil at an elevated temperature, preventing refrigerant absorption and protecting your investment.

Application

• Designed for use with York HVAC systems and compatible equipment
• Ideal for residential and light commercial applications
• Suitable for replacement in systems where the original crankcase heater has failed or is showing signs of wear
