Lennox 100483-21 Condenser Fan Motor – Genuine OEM 1/5 HP 208-230V 1075 RPM 42 Frame

The Lennox 100483-21 (Catalog # 43W49) is a high-efficiency permanent split capacitor (PSC) condenser fan motor, acting as the primary heat-rejection "engine" for your outdoor cooling system. This 1/5 HP motor drives the fan blades that pull ambient air across the condenser coils, ensuring the refrigerant is cooled effectively to maintain indoor climate control. Specifically engineered for Lennox, Armstrong, and Ducane air conditioning and heat pump series, this motor features a compact 42-frame diameter. By maintaining a precise 1075 RPM, it ensures your outdoor unit stays within its engineered thermal limits, preventing compressor overheating and extending the life of your entire HVAC system.

Key Features and Function:

Precision Airflow Management: Calibrated to 1075 RPM to provide the exact CFM (Cubic Feet per Minute) required to shed heat from the outdoor coils without over-stressing the electrical circuit.
Genuine OEM Reliability/Fitment: Designed by Lennox as a direct "drop-in" replacement, ensuring the specialized 42-frame mounting and shaft length align perfectly with the original fan shroud.
Heavy-Duty Weatherproof Build: Features a "Totally Enclosed Air Over" (TEAO) enclosure and permanently lubricated bearings to resist rain, dust, and debris in harsh outdoor environments.
Direct-Fit Design/Plug-and-Play: Includes factory-coded wiring leads and an integrated plug system (where applicable) for a simplified installation that restores factory performance.

🛠️ HVAC Depot Pro Tip: The 42-Frame Check

When installing the 100483-21, verify your frame size. This is a 42-frame motor (5" diameter), which is smaller than the standard 48-frame (5-5/8"). Attempting to use a standard motor in a 42-frame bracket will not fit. During your Diagnostic Check, always replace the 5 MFD run capacitor at the same time; a weak capacitor is the leading cause of "thermal tripping" where the motor shuts off after running for only a few minutes. Always ensure the water slinger is positioned correctly to keep moisture out of the bearings.

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.

Verified Buyer

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.

Paul Hamer

My AC went out in our home on Friday night. I went out and got the capacitor details and took them here first thing Saturday morning. Lady at the counter was friendly and had the capacitor I needed! When I got home, I installed the capacitor and AC is all good!!
