Lennox 56W68 Inducer Assembly

The Lennox 56W68 Inducer Assembly is a critical OEM replacement part engineered for high-efficiency Lennox furnace systems. This draft inducer blower (part number 56W68, identical to 56W6801) functions as a 120V, single-phase 1/10 HP motor assembly designed to ensure optimal combustion air intake and safe exhaust gas removal. Featuring a robust 3000 RPM operation at 1.4 Amps, this unit replaces legacy part numbers including R44431-001 and satisfies the rigorous venting requirements of residential HVAC equipment. This assembly is a standard technical solution for furnace repair when encountering pressure switch faults or inducer motor bearing failure. Built to manufacturer specifications, it provides precise airflow management and maintains system static pressure for consistent ignition cycles and maximum thermal efficiency. This genuine furnace draft motor is critical for restoring peak performance in compatible Lennox HVAC units while ensuring quiet, reliable operation throughout the heating season.

Key Benefits:

• Direct OEM Compatibility: Engineered for a precise fit with Lennox systems, replacing 56W68, 56W6801, and R44431-001 without field modifications.
• Enhanced Combustion Safety: Effectively removes flue gases to prevent carbon monoxide buildup and ensure reliable pressure switch activation.
• Industrial Build Quality: Features a 1/10 HP motor with high-temperature resistance and 3000 RPM capacity for long-cycle reliability.
• Optimized Efficiency: Restores factory-spec airflow, improving fuel utilization and reducing operational noise during the startup cycle.

Common Questions:

Is the Lennox 56W68 the same as 56W6801?
Yes, these are identical part numbers. The 56W68 is the current manufacturer designation for the 56W6801 inducer assembly used in many Lennox-brand furnaces.

What are the signs that my inducer assembly needs replacement?
Common indicators include a loud grinding or screeching noise upon furnace startup, a "pressure switch stuck open" error code on the control board, or the blower failing to spin while under voltage.

Should I replace the gasket when installing this part?
Technicians strongly recommend using a new OEM gasket or high-temperature silicone sealant during installation to maintain a gastight seal between the inducer and the collector box, preventing exhaust leaks.
