Carrier HT32CH764 Crankcase Heater

Description

The Carrier HT32CH764 is an OEM crankcase heater engineered to protect the compressor in compatible Carrier HVAC systems. Crankcase heaters are a critical component in refrigeration and air conditioning equipment, keeping the compressor oil warm during off-cycles to prevent refrigerant from migrating into and diluting the lubricating oil. This helps ensure reliable compressor startups, extends compressor life, and reduces the risk of costly failures caused by liquid slugging or oil foaming.

Key Features

• OEM Carrier replacement crankcase heater — SKU HT32CH764
• Prevents refrigerant migration into compressor oil during off-cycles
• Helps protect compressor from liquid slugging and oil dilution
• Maintains optimal oil viscosity for reliable compressor startups
• Designed for direct OEM replacement in compatible Carrier systems
• Supports extended compressor service life and system efficiency

Application

This crankcase heater is intended for use with compatible Carrier air conditioning and refrigeration equipment. Always verify compatibility with your specific Carrier model before installation. Consult the equipment service manual or contact your Carrier distributor for full application guidance.

Why Crankcase Heaters Matter

During extended off periods — especially in cold ambient conditions — refrigerant can condense and accumulate in the compressor crankcase. When the system restarts, this refrigerant-oil mixture can cause severe mechanical damage. A properly functioning crankcase heater eliminates this risk by continuously warming the crankcase, keeping refrigerant in the vapor phase and oil at the correct viscosity.
