Description
The Carrier HT32BH948 is a genuine OEM 230V crankcase heater engineered to protect compressor integrity in Carrier HVAC systems. Crankcase heaters are a critical component in refrigeration and air conditioning equipment, preventing 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 dissolve into the compressor oil and settle in the crankcase. When the system restarts, this refrigerant-oil mixture can cause slugging, oil foaming, and severe mechanical wear. The HT32BH948 maintains a consistent heat level around the compressor crankcase to keep oil at the proper viscosity and prevent refrigerant absorption, extending compressor life and protecting your investment.
