Description
The York S1-025-47167-000 is an OEM band-style crankcase heater engineered to maintain proper oil viscosity in the compressor crankcase, preventing refrigerant migration and oil dilution during off-cycle periods. This is a direct factory replacement part designed for use in York HVAC systems.
Why Crankcase Heaters Matter
During extended off cycles — especially in cold ambient conditions — liquid refrigerant can migrate into the compressor crankcase and mix with the lubricating oil. When the compressor starts, this refrigerant-oil mixture can cause slugging, bearing wear, and premature compressor failure. A properly functioning crankcase heater keeps the oil warm, maintains the correct viscosity, and ensures reliable compressor starts every time.
