Lennox Furnace Draft Inducer Motor Parts
The draft inducer motor is the first part to fire during a Lennox furnace heating cycle. It creates negative pressure in the heat exchanger and venting system, allowing fuel and air to mix safely for ignition. When the inducer motor fails, your furnace won't start — or it starts, then immediately shuts down when the pressure switch detects insufficient draft.
Common signs of inducer motor failure: rattling or grinding noise from the furnace, a brief startup attempt followed by shutdown, or complete no-heat condition with no blower action. The inducer assembly includes the motor, wheel/impeller, and housing. Always match the horsepower (HP) rating and mounting flange dimensions to your Lennox model using your serial number. Lennox furnace draft inducer motors are model-specific — aftermarket substitutes often have incorrect pressure curves and won't satisfy the pressure switch.
- Furnace starts then shuts down after 10-30 seconds: Inducer motor not reaching full speed; pressure switch trips
- Rattling or grinding noise from furnace cabinet: Motor bearing failure or damaged wheel/impeller inside housing
- No furnace response when thermostat calls for heat: Inducer motor dead; furnace safety prevents ignition without draft
- Error code on Lennox iComfort board: Pressure switch fault; often caused by weak inducer motor performance
- Whistling or high-pitched noise during operation: Bent or damaged impeller blade; full assembly replacement needed

Lennox Draft Inducer Motor FAQ
How do I know if my Lennox furnace inducer motor has failed?
The most telling sign is a furnace that starts, runs for 5 to 30 seconds, then shuts down automatically. You may also hear grinding, rattling, or squealing from inside the furnace cabinet. If the pressure switch is continuously tripping (error codes on iComfort boards), the inducer motor is often the culprit. A failed inducer won't create enough negative pressure to satisfy the safety interlock.
What's the difference between Lennox inducer motors by model?
Lennox uses different motor assemblies across their product lines — especially between the Dave Lennox Signature series (SLP98V) and the Elite/Merit models. Motor horsepower, voltage (most are 115V, some 230V), and the impeller/wheel configuration vary significantly. Enter your exact Lennox model number and serial number to get the OEM-correct assembly. Using a generic or cross-brand motor will likely fail the pressure switch test and leave you with a non-functional furnace.
Can I replace just the motor shaft or bearing?
No. The inducer motor assembly is sealed and not field-serviceable. When the motor bearing fails or the shaft bends, the entire assembly — motor, wheel, housing, and mounting bracket — must be replaced as one unit. OEM replacement assemblies are tested to exact pressure and airflow specifications for your Lennox model.
Why is an OEM Lennox inducer motor more expensive than aftermarket options?
OEM Lennox motors are engineered to produce specific pressure curves and airflow volumes. Aftermarket or generic motors may physically fit the mounting flange but generate insufficient draft — causing the pressure switch to misfire, furnace lockouts, and service issues. Lennox iComfort communicating controls are especially sensitive to pressure switch timing. Always use the OEM assembly.
