Fasco A163 Motor

The Fasco A163 Draft Inducer Motor is an OEM-quality replacement motor engineered by Regal Rexnord for high-static pressure applications in Lennox and Armstrong gas furnaces. This 115V single-speed shaded pole motor operates at 3400 RPM, providing the necessary torque to clear combustion gases and ensure proper pressure switch engagement. As a direct drop-in for the Lennox 68K21, the A163 includes the necessary fitting and an inlet gasket to simplify field replacement. The 1/20 HP unit features a CCWSE rotation and utilizes high-grade ball bearings rather than sleeve bearings to manage heat dissipation and extend service life in high-temperature flue environments. With a 1.8 Amp draw and a standard 2-pin connector, this furnace inducer motor restores system sequence of operation and combustion efficiency.

Key Benefits for Technicians:

• Direct Cross-Reference: Exact replacement for Lennox 68K21, 7021-9450, and 7021-10302, eliminating mounting modifications.
• Enhanced Durability: Equipped with dual ball bearings to withstand the continuous duty cycles of residential heating.
• Installation Ready: Includes the critical 68K21 fitting and gasket for a complete seal against the collector box.
• Specifications: 115 Volts, 60 Hz, 1.8 Amps, 3400 RPM, 1-speed, shaded pole design.

Common Questions:

Does this motor include the furnace pressure switch fitting?
Yes, as the designated cross for the Lennox 68K21, this assembly includes the required fitting for the vacuum line connection.

What causes a draft inducer motor to fail prematurely?
Common failure points include bearing seizure due to high flue temperatures or moisture buildup within the housing. The Fasco A163 uses ball bearings to better handle these stressors compared to standard OEM sleeve motors.

Is this compatible with 80% and 90% AFUE furnaces?
The A163 is specifically designed for certain Lennox, Armstrong, and Ducane models. Always verify the RPM and Amperage match the data plate of the failed unit to ensure proper draft velocity.
