Lennox 48L96 Inducer Assembly

The Lennox 48L96 Inducer Assembly is a high-performance direct replacement draft inducer engineered for precise flue gas evacuation in residential and commercial furnaces. Built by Fasco (Type U21B), this 115V, 3400 RPM motor assembly provides the specific static pressure required to maintain proper air-fuel ratios and clear combustion byproducts from the heat exchanger. This unit serves as a critical OEM furnace repair part for Lennox, Armstrong, and Ducane equipment, successfully superseding older versions including the LB-65734J, 7021-10721, and 7021-10893. The assembly features a 1.8A to 2.5A draw with a thermally protected motor and sealed ball bearings, ensuring long-term operational stability in high-heat environments. With a 2-inch outlet and inlet configuration, this centrifugal blower facilitates a seamless drop-in installation for technicians focused on restoring system efficiency. For HVAC professionals, the 48L96 is a standard-issue component for troubleshooting ignition failures and pressure switch circuit errors in compatible GHR26 and GHR32 series units.

• Optimized Flue Venting: High-speed 3400 RPM operation ensures consistent draft pressure to prevent pressure switch trips and combustion instability.
• Broad Compatibility: Serves as a direct cross-reference for multiple legacy Fasco inducer motor models across Lennox, Armstrong, and Magic-Pak lines.
• Industrial Grade Construction: Features sealed ball bearings and a thermally protected housing to withstand the rigorous cycling of modern high-efficiency furnaces.
• Streamlined Installation: Compact 2" inlet/outlet design allows for rapid replacement in the field, minimizing downtime for the end-user.

Which Lennox furnace models are compatible with the 48L96?
This Lennox inducer assembly is primarily compatible with GHR26Q, GHR32, and various Armstrong/Ducane models. Always verify the specific HVAC part number on the existing blower housing before installation.

Does the 48L96 include the necessary installation gasket?
Yes, this assembly typically includes the mounting gasket and hardware required to create an airtight seal against the collector box, ensuring no CO leakage into the mechanical room.

What are the signs that my current 48L96 inducer needs replacement?
Common indicators for technicians include excessive bearing noise (grinding/squealing), failure to close the pressure switch, or a complete seized motor resulting in a "No Heat" service call.
