York 025-37852-000 Crankcase Heater Els PW 29614 While this is a commonThe York 025 37852 000 Crankcase Heater is a critical OEM component designed for high performance HVAC compressor maintenance. Operating at 120V and delivering 120W of consistent thermal energy, this heater ensures that refrigerant remains separated from the compressor oil during the off cycle. By maintaining elevated lubricant temperatures, it prevents refrigerant migration and the subsequent risk of slugging upon startup, which is a primary cause of
