Description
The York 025-27924-000 Crankcase Heater is a genuine OEM replacement component engineered to protect compressors in York HVAC systems from the damaging effects of refrigerant migration and liquid slugging.
Why Crankcase Heaters Matter
During off-cycle periods, refrigerant can migrate into the compressor crankcase and mix with the oil. When the compressor starts, this refrigerant-oil mixture can cause liquid slugging, foaming, and accelerated wear — leading to premature compressor failure. A properly functioning crankcase heater keeps the compressor oil warm enough to prevent refrigerant absorption, safeguarding one of the most expensive components in any HVAC system.
