Carrier HT32CH231 Crankcase Heater 321894-709 the sampling tube must beThe Carrier HT32CH231 Crankcase Heater is a critical OEM replacement part designed to maintain optimal compressor health in specialized HVAC and refrigeration systems. This 240V, 40W heater functions as a belly band heater, wrapping around the base of the compressor to stabilize oil temperature during the off cycle. By keeping the lubricant warm, it prevents refrigerant migration and subsequent oil dilution, which are primary causes of liquid slugging
