Lennox 99C33 Inducer Blower Assembly

The Lennox 99C33 Inducer Blower Assembly is a direct OEM replacement engineered for high-efficiency furnace combustion systems. Designed to facilitate the precise venting of flue gases, this assembly ensures the pressure switch closes correctly to initiate the ignition sequence. This furnace draft inducer motor is critical for maintaining proper air-to-fuel ratios and preventing the buildup of combustion byproducts within the heat exchanger. It serves as a direct replacement for 99C3301, offering a drop-in fit that reduces labor time during emergency service calls. The unit features a durable housing and a precision-balanced impeller to minimize vibration and harmonic noise during the heating cycle. For technicians troubleshooting Lennox furnace pressure switch errors or bearing failure, the 99C33 provides the specified CFM and static pressure required to meet factory performance curves. Its robust motor windings are built to withstand the high ambient temperatures common in confined mechanical rooms and attic installations.

• OEM Compatibility: Exact replacement for Lennox 99C33 and 99C3301, ensuring electrical and mounting alignment.
• Optimized Airflow: Engineered to provide the specific static pressure required for safe venting and flue gas evacuation.
• Streamlined Installation: Features the standard wiring harness and mounting footprint for rapid field replacement.
• Operational Efficiency: Balanced blower wheel assembly reduces mechanical stress on the motor, extending the component lifecycle.

Does this assembly include the integrated cooling fan for the motor?
Yes, the 99C33 assembly includes the internal cooling fan designed to dissipate heat from the motor windings during extended run cycles.

Will this resolve a 'Pressure Switch Stuck Open' fault?
If the existing motor is failing to reach the necessary RPM or the housing is compromised, replacing it with this assembly will restore the required vacuum to close the pressure switch.

Is the mounting gasket included with this part?
This kit typically includes the necessary hardware and seals required for a standard installation, though verifying the condition of the existing collector box port is recommended.
