This Fasco A217 draft inducer blower motor is a factory-spec replacement for select Fasco and Lennox gas furnaces. Running at 3000 RPM on 208-230V single-phase power, it restores proper combustion air management and venting performance. Ball bearing construction, built-in thermal protection, and Class B insulation make it a durable, long-service drop-in repair part. Also catalogued under NBK Parts number 12170.
A failing draft inducer motor is one of the most common causes of furnace lockout, pressure switch faults, and incomplete ignition sequences. This Fasco A217 motor pulls combustion gases through the heat exchanger and out the flue before and during burner operation -- a critical function in induced-draft and direct-vent gas furnace designs.
Designed to match the original Fasco OEM motor used in Lennox furnaces, this replacement restores correct airflow rates, pressure switch operation, and venting efficiency without modification. The 15-inch leads with spade terminals connect directly to existing furnace wiring harnesses on the models listed below.
Ball bearings provide longer service life and quieter operation compared to sleeve bearing alternatives, especially in continuous or high-cycle furnace duty.
Integrated thermal overload protection automatically shuts the motor down if it overheats, protecting the furnace control board and heat exchanger.
Class B winding insulation is rated for continuous operation in furnace environments up to 130 deg C winding temperature rise, well suited to hot-area mounting.
15-inch leads with spade terminals match OEM wiring length and connector style, making reconnection straightforward on covered models.
This motor is a verified direct replacement for the following part numbers:
Always verify your existing motor's voltage, RPM, rotation direction, and mounting configuration against the specs listed here before ordering. Lennox and Fasco furnaces using this inducer motor are typically found in the G series and related single-stage upflow and horizontal configurations -- confirm your model number against the part numbers above.
Draft inducer motors are mounted to the inducer housing assembly, which is secured to the furnace vestibule panel. On most Lennox applications using this motor:
