Description
Product Overview
The International Comfort Products 1173944 is an OEM crankcase heater engineered to safeguard refrigeration compressors from the damaging effects of refrigerant migration during off-cycle periods. By maintaining the compressor oil at an elevated temperature, this heater prevents liquid refrigerant from mixing with the lubricating oil — a leading cause of compressor failure, especially during cold-weather startups.
Key Features
- Operating Voltage: 240 Volts
- Wattage: 40 Watts
- OEM replacement part from International Comfort Products (ICP)
- Designed to prevent refrigerant migration into compressor oil during off cycles
- Helps extend compressor service life and reduce costly failures
- Direct-fit replacement for compatible ICP equipment
Why Crankcase Heaters Matter
Refrigerant migration occurs when the system is off and ambient temperatures drop, causing refrigerant vapor to condense and dissolve into the compressor oil. When the compressor restarts, this refrigerant-oil mixture can cause slugging, oil foaming, and premature bearing wear. Installing a properly rated crankcase heater — like this 240V/40W unit — keeps the compressor sump warm and the oil free of liquid refrigerant, ensuring reliable startups and longer equipment life.
Application
- Replacement crankcase heater for International Comfort Products systems
- Suitable for residential and light commercial HVAC applications
- Consult equipment documentation to confirm compatibility before installation
Installation Notes
Always de-energize the system before servicing. Verify that the supply voltage matches the heater’s 240V rating. Follow all applicable local codes and manufacturer guidelines during installation. For best results, allow the crankcase heater to operate for a minimum warm-up period before starting the compressor after extended off periods.
