Lennox 57W64 Coil
The Lennox 57W64 Secondary Heat Exchanger Coil serves as a critical replacement component for high-efficiency condensing gas furnaces within the Lennox G61MPV and G61V series. This stainless steel condensing coil is engineered to extract latent heat from combustion gases, maximizing the AFUE rating of the HVAC system. As a Lennox OEM replacement part, it ensures precise fitment and structural integrity within the heat exchanger assembly. Technicians must ensure the plenum is properly inspected for signs of stress or corrosion when performing a cell swap. This furnace secondary coil is designed to handle corrosive condensate while maintaining optimal thermal transfer. Integration requires verifying the 57W64 heat exchanger compatibility with specific furnace input BTUs to ensure proper static pressure and airflow across the secondary cell. Replacing a failed secondary coil restores the furnace's condensing capability and prevents combustion bypass issues in Lennox furnace repair applications.
Key Benefits
- Aluminized or Stainless Steel Construction: Designed to resist the corrosive nature of acidic condensate formed during the combustion process.
- OEM Fitment: Eliminates the need for field modifications, ensuring direct replacement compatibility with G61 series units.
- Thermal Efficiency: Restores the unit's ability to achieve 90%+ AFUE by capturing heat that would otherwise be lost through the flue.
- System Longevity: Prevents premature inducer motor failure and pressure switch trips by maintaining proper internal combustion aerodynamics.
Common Questions
What are the signs that a Lennox secondary heat exchanger is failing?
Common indicators include a persistent "chemical" smell, excessive water in the burner compartment, or recurring pressure switch codes (usually indicating a restricted secondary cell or inducer assembly blockage).
Is the Lennox 57W64 compatible with all G61 series furnaces?
This specific part is sized for specific BTU inputs. Technicians should verify the full model and serial number to ensure the coil footprint matches the original secondary cell assembly.
Does this secondary coil include the header box or gaskets?
This component typically consists of the coil cell itself. Installers should source required high-temp RTV or specific Lennox gasket kits separately to ensure a gas-tight seal during reassembly.
