Nordyne 632677 Crankcase Heater
Ensure your compressor remains protected against liquid refrigerant migration with the Nordyne 632677 Crankcase Heater. This 240V 40W heater is a critical preventative measure for HVAC systems operating in fluctuating ambient conditions. By maintaining the oil at a temperature higher than the rest of the circuit, this crankcase heater replacement effectively eliminates the risk of oil slugging and high-pressure foaming during startup. Designed for a belly band or wrap-around installation, this 60-inch lead component provides reliable heat transfer to the compressor sump, significantly reducing the mechanical stress caused by flooded starts. For technicians managing commercial or residential Nordyne split systems, verifying the performance of this compressor heater is vital to extending the operational life of the unit and preventing catastrophic valve failure. This core electrical component integrates seamlessly into existing low-ambient control circuits, ensuring your refrigeration parts inventory is ready for harsh winter cycles.
Key Benefits- Prevents Refrigerant Migration: Stops liquid refrigerant from condensing in the compressor oil during the off-cycle, preventing flooded starts.
- Industrial-Grade 240V Output: Delivers consistent 40W of heat to maintain optimal lubricant viscosity for immediate lubrication upon startup.
- Versatile 60-Inch Leads: Offers flexible wiring options for various compressor heights and enclosure configurations.
- Enhanced Compressor Longevity: Protects internal discharge valves and reeds from the violent impact of oil-refrigerant foaming.
- OEM Compatibility: Specifically engineered for Nordyne 632677 replacement standards to ensure proper fitment on approved compressor models.
Why is the 240V crankcase heater necessary for my HVAC system?
It keeps the compressor crankcase warmer than the coldest part of the system, forcing refrigerant to stay in the condenser or evaporator and preventing it from diluting the compressor oil.
Can I test the Nordyne 632677 for proper operation without removing it?
Yes, seasoned techs should use an amp probe to verify current draw when the contactor is open (assuming the common-wire side remains energized) or check for continuity across the leads while disconnected from the power source.
What happens if the crankcase heater fails in winter?
Failure leads to "oil slugging," where liquid refrigerant and oil mix. On startup, this mixture foams and is pumped through the valves, which can lead to broken internal components and total compressor failure.
