Lennox 43K30 Vent Motor Assembly

The Lennox 43K30 Vent Motor Assembly is a high-performance direct replacement draft inducer blower engineered for specific Lennox unit heaters and furnace models. Operating at 120V with a fixed speed of 3000 RPM, this 0.017 HP shaded pole motor is designed to meet strict OEM draft inducer specs for safe combustion byproduct extraction. It features a counter-clockwise opposite shaft end (CWOSE) rotation and is officially cross-referenced with Lennox part number 43K3001 and 65238200.

Built for durability in demanding HVAC environments, the 43K30 ensures consistent static pressure and airflow, preventing nuisance pressure switch trips and maintaining peak system efficiency. This assembly typically services Lennox LF24 series unit heaters, including popular models like the LF24-50, LF24-75, and UHPA090AE-5. Verified as a genuine Lennox OEM replacement part, this 60Hz assembly provides a precise fit without the need for field modifications, ensuring reliable ignition and safe venting throughout the heating cycle.

• Precision Airflow: Maintains the exact 3000 RPM required for proper heat exchanger drafting.
• OEM Compatibility: A drop-in replacement for Lennox 43K3001 and 65238200, ensuring zero-clearance mounting issues.
• Enhanced Safety: Engineered to effectively exhaust carbon monoxide and combustion gases from the furnace.
• Application Versatility: Widely used in LF24-75A-02, LF24-50A-02, and LF24-50S-02 unit heaters.

Is the 43K30 compatible with the older 43K3001?
Yes, the 43K30 is the direct, identical successor to the 43K3001. It shares the same electrical specifications and mounting footprint.

Will this motor fix a furnace that keeps tripping the pressure switch?
If the existing vent motor assembly is failing to reach its rated 3000 RPM or the inducer wheel is clogged, replacing it with the Lennox 43K30 will restore the necessary draft to close the pressure switch and allow the ignition sequence to complete.

Can this be used for 208-230V applications?
No, this specific assembly is rated for 120V operation only. Using it with higher voltage will result in immediate motor failure.
