Carrier HT32BH390 Crankcase Heater

Description

The Carrier HT32BH390 is a genuine OEM crankcase heater engineered to protect the compressor in compatible Carrier HVAC systems. By maintaining the crankcase oil at an elevated temperature during off-cycles, this heater prevents refrigerant from migrating into and mixing with the compressor oil — a leading cause of compressor damage and premature failure.

Why Crankcase Heaters Matter

During extended shutdown periods, refrigerant can migrate to the compressor crankcase and dissolve into the lubricating oil. On startup, this refrigerant-oil mixture can cause slugging, oil foaming, and loss of lubrication — all of which dramatically shorten compressor life. A properly functioning crankcase heater eliminates this risk by keeping the oil warm and refrigerant-free.
