Description
The Carrier HT32BH861 is an OEM crankcase heater engineered to protect the compressor in compatible Carrier HVAC systems. By maintaining a consistent temperature around the compressor crankcase, this heater prevents refrigerant from migrating into the compressor oil during off-cycles — a leading cause of compressor damage and premature failure.
Why Crankcase Heaters Matter
During extended shutdown periods, refrigerant can accumulate in the compressor oil sump. When the system restarts, this refrigerant-oil mixture can cause slugging, which strips lubrication from critical compressor components and leads to costly failures. The HT32BH861 keeps the crankcase warm enough to drive off refrigerant, ensuring the compressor is ready for reliable start-up every time.
