Description
Overview
The International Comfort Products 1174709 is a 240-Volt, 40-Watt crankcase heater engineered to protect refrigerant compressors from refrigerant migration and oil dilution during off-cycle periods. By maintaining the compressor crankcase at an elevated temperature, this heater prevents liquid refrigerant from mixing with the compressor oil — a leading cause of compressor failure, especially during cold-weather startups. This is a genuine ICP OEM replacement part designed to deliver reliable, long-term performance in compatible systems.
Key Features
- Operating Voltage: 240 Volts
- Wattage: 40 Watts
- Prevents refrigerant migration into compressor oil during off cycles
- Reduces risk of compressor damage caused by liquid slugging on startup
- Genuine OEM International Comfort Products replacement part
- Direct replacement for compatible ICP systems
Why Crankcase Heaters Matter
During extended off cycles — particularly in cooler ambient conditions — refrigerant can migrate to the compressor crankcase and dissolve into the lubricating oil. When the compressor restarts, this refrigerant-oil mixture can cause oil foaming and liquid slugging, leading to premature compressor wear or catastrophic failure. A properly functioning crankcase heater eliminates this risk by keeping the crankcase warm, ensuring the oil remains free of refrigerant at startup.
Application
