Heil 1173944 Crankcase Heater 40W 240V

The Heil 1173944 is a 40-watt crankcase heater designed for 240-volt HVAC systems. This OEM replacement component is manufactured by International Comfort Products (ICP) for Heil, Tempstar, Arcoaire, Comfortmaker, and other branded systems.

What It Does:

The crankcase heater prevents refrigerant migration and mixing with crankcase oil when the compressor is not running. It keeps refrigerant at a temperature higher than the coldest part of the system, protecting your compressor from damage during off-cycles and startup.

Key Specifications:

• Voltage: 240V
• Wattage: 40W
• Lead Length: 60 inches
• Country of Origin: USA

Cross-Reference Part Numbers:

Also known as CH245, Tutco 40W240V, and CC HTR WP. This heater is compatible with multiple ICP family brands including Heil, Tempstar, Arcoaire, Comfortmaker, Snyder General, KeepRite, and Day & Night.

Why It Matters:

A missing or failed crankcase heater is a leading cause of premature compressor failure. During system shutdown, refrigerant can migrate into the compressor oil, creating a diluted mixture that fails to properly lubricate bearings and moving parts. The crankcase heater operates when the compressor is off, maintaining oil temperature and preventing costly compressor damage.

This genuine OEM part ensures reliable protection for your HVAC system's compressor, extending equipment life and preventing expensive repairs.
