Description
The AAON G006450 is a genuine OEM crankcase heater engineered to protect compressors in AAON commercial HVAC equipment. Operating at 480 volts and 70 watts, this heater keeps compressor oil warm during off-cycles, preventing refrigerant migration into the crankcase and reducing the risk of compressor damage on startup. The integrated fuse (W/FU) adds an extra layer of electrical protection, helping guard against overcurrent conditions and extending the service life of the assembly.
Key Features
- Genuine AAON OEM replacement part — SKU G006450
- Operating voltage: 480V
- Power rating: 70 watts

Why Crankcase Heaters Matter
During extended off-cycles — especially in cold ambient conditions — refrigerant can migrate and mix with compressor oil. When the compressor restarts, this refrigerant-oil mixture can cause liquid slugging, leading to premature compressor failure. A properly functioning crankcase heater maintains oil temperature to prevent this condition, protecting one of the most costly components in any HVAC system.
Application
- Replacement crankcase heater for compatible AAON commercial HVAC units
