International Comfort Products NASA00601CH Crankcase Heater for HVAC Compressors

The International Comfort Products NASA00601CH Crankcase Heater is a genuine OEM replacement heater designed to protect HVAC compressors from oil migration and refrigerant dilution during off-cycle periods. By maintaining a consistent temperature around the compressor crankcase, this heater prevents liquid refrigerant from mixing with compressor oil — a leading cause of compressor failure, especially during cold-weather startups.

Key Features:

• Genuine International Comfort Products (ICP) OEM replacement part
• Manufacturer Part Number: NASA00601CH
• Wraps around or mounts directly to the compressor body for efficient heat transfer
• Protects compressor oil from refrigerant dilution during system off-cycles
• Reduces risk of compressor damage caused by liquid slugging on startup
• Designed for use in residential and light commercial HVAC systems
• Direct OEM replacement ensures proper fit and performance

Crankcase heaters are a critical component in any split-system heat pump or air conditioner operating in climates where ambient temperatures can drop significantly. The NASA00601CH is engineered to meet International Comfort Products' strict quality standards, making it the ideal replacement for worn or failed crankcase heaters in compatible ICP, Heil, Tempstar, Arcoaire, Comfortmaker, and other affiliated brand systems.
