Description
Rheem-Ruud 44-17402-45 Belly Band Crankcase Heater
The Rheem-Ruud 44-17402-45 is an OEM replacement belly band crankcase (CC) heater engineered to protect compressor integrity in Rheem and Ruud HVAC systems. By maintaining oil temperature during off-cycles, this heater prevents refrigerant migration into the compressor crankcase — a leading cause of compressor damage and premature failure.
Key Features
- OEM Rheem-Ruud replacement part — ensures proper fit and performance
- Belly band design wraps directly around the compressor body for efficient, consistent heat transfer
- 240V operating voltage for compatibility with standard residential and light commercial systems
- 40W wattage delivers targeted warmth to prevent refrigerant migration during compressor off-cycles
- Crankcase heater (CC) function protects compressor oil viscosity in cold ambient conditions
- Durable construction built to Rheem-Ruud OEM specifications
Why Crankcase Heaters Matter
During extended off-cycles — especially in cold weather — liquid refrigerant can migrate into the compressor crankcase and dilute the lubricating oil. When the compressor starts, this refrigerant-oil mixture can cause slugging, bearing wear, and catastrophic compressor failure. The 44-17402-45 belly band heater keeps the crankcase warm enough to drive off refrigerant and maintain proper oil viscosity, extending compressor life and reducing costly service calls.
