Description
The Carrier HT32CH766 is a genuine OEM crankcase heater designed to protect the compressor in compatible 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 condition that can cause oil dilution, poor lubrication, and premature compressor failure.
Why Crankcase Heaters Matter
During extended shutdown periods, refrigerant can accumulate in the compressor crankcase and mix with the lubricating oil. When the system restarts, this refrigerant-oil mixture can cause slugging, foaming, and accelerated wear on compressor components. The HT32CH766 crankcase heater keeps the compressor sump warm, ensuring refrigerant remains in the vapor state and oil maintains its proper viscosity for reliable startup.

Installation Notes
Always de-energize the system before replacing a crankcase heater. Allow adequate warm-up time after installation before restarting the compressor. Consult Carrier OEM documentation for specific wiring and mounting instructions for your equipment model.
For guaranteed compatibility, reference your equipment model number against Carrier’s parts cross-reference guide or contact your Jackson Systems representative.
