Lennox LB-29333BJ – Genuine OEM Replacement Direct Drive Blower Wheel

The Lennox LB-29333BJ (also identified by catalog number 21708) is a high-quality direct drive blower wheel (also known as a "squirrel cage") engineered for use in a vast range of Lennox, Armstrong, and Ducane HVAC systems, including furnaces and air handlers. This wheel is the heart of your HVAC system's airflow, responsible for circulating large volumes of conditioned air through the home’s ductwork. By maintaining the correct static pressure, this wheel ensures efficient operation and protects critical components like the heat exchanger.

As a Genuine OEM part, the LB-29333BJ is constructed from heavy-duty galvanized steel and factory-balanced to ensure quiet, vibration-free operation. This is critical for protecting the blower motor's internal bearings and extending the overall life of the blower assembly. Designed with a 1/2" bore, this wheel offers a precision "direct-fit" solution that eliminates the alignment issues often found with universal aftermarket components, ensuring your system runs at peak factory efficiency.

Key Features and Function:

Feature 1: High-Efficiency Airflow Management – Designed with 48 blades and a specific pitch to move maximum air volume with minimal noise.
Feature 2: Genuine OEM Reliability/Fitment – Direct replacement for Lennox equipment, ensuring the wheel clears the housing perfectly.
Feature 3: Corrosion-Resistant Galvanized Steel – Built to withstand the humidity and temperature fluctuations within the HVAC cabinet.
Feature 4: Precision Balanced Hub – Reduces mechanical stress on the blower motor, preventing premature motor failure.

🛠️ HVAC Depot Pro Tip: The Set-Screw Alignment

When installing the LB-29333BJ, always ensure the motor shaft has a "flat" spot. Secure the set screw directly onto this flat section—never the rounded part of the shaft. This critical step prevents the wheel from slipping during high-speed operation, which causes loud noise and severe imbalance.

The LB-29333BJ is a direct OEM replacement for the following part numbers:

OEM Numbers:

Happy Shouts From Our Thrilled Customers

William Bartlett

Cecil really saved me with troubleshooting tips over the phone. Thought I was going to have to replace the blower motor and ended up only needing a motor run capcitor. Thank you and God bless!

Verified Buyer

Riley Connolly

Cecil and Fidel were absolutely amazing and so helpful. We were happy they were open on Sunday, but was impressed with their knowledge and willingness to make sure we had everything we needed. If you need parts or service or install, I would recommend.

Verified Buyer

Cole Meger

Our AC went out during the hottest stretch of summer, and with a one-year-old at home, we were desperate for a quick fix. These guys came through big time — not only did they source the part faster than anyone else in the area, they also walked me through DIY troubleshooting while I waited. Trustworthy, knowledgeable, and run by a solid local family. As someone who owns rental properties nearby, I’ll be sourcing all my HVAC parts from them moving forward. Highly recommend!

Verified Buyer

Carl T. Droste

Had a power outage last night and during the 100 degree heat today noticed that the AC was not blowing any cold air. Pulled the capacitors to have them checked and also took video of the relay making noise even with the breaker was off. The proprietor and her staff were very friendly and helpful. She had the video analyzed and confirmed something was wrong. She checked one of the capacitors was a little low. Capacitor replacement is the biggest ticket item for HVAC repair. It is hundreds of dollars with the a capacitor only about $20.

Fuzzy Wuzzy

Cecil and his family have been a life saver. I walked in with very little knowledge on parts let alone how to repair my unit. All I had was my brother in FL who knows more than I do and Cecil at HVAC Depot. With 2 young kids at home I couldn't afford to wait for a HVAC tech. Cecil walked me through what I needed to know, even after hours when the shop closed. I successfully repaired the fan motor and replaced the capacitor. Thank you HVAC team for being totally awesome. Prices were amazing and I'm forever going to support this small family business. You and your family are what Texas is all about!!!

Verified Buyer

Linda Robinson

I called HVAC Depot and was absolutely blown away by the fast, courteous and exceptional service. They were very knowledgeable about explaining what they were doing and what had happened to the ac system. If you ever need a HVAC team they are best and they won’t hesitate by coming out and they won’t leave until you are happy with the service. Thank you so much for your excellent service. Kudos to you Michelle for your amazing customer service.
