Description
The York 025-45788-000 is an OEM crankcase heater engineered to protect compressor longevity in York HVAC systems. Operating at 70 watts and 120 volts, this heater maintains the compressor crankcase at an elevated temperature during off-cycles, preventing refrigerant from migrating into and mixing with the compressor oil. This critical function guards against liquid slugging at startup — one of the leading causes of premature compressor failure.
Why Crankcase Heaters Matter
During extended off-cycles, especially in cold ambient conditions, refrigerant vapor can condense and accumulate in the compressor crankcase. When the system restarts, this refrigerant-oil mixture can cause hydraulic slugging, oil foaming, and accelerated bearing wear. A properly functioning crankcase heater eliminates this risk by keeping the oil warm and refrigerant-free at all times.
