Lennox 81W36 Motor
The Lennox 81W36 is a high-efficiency 3/4 HP X-13 programmed motor designed for constant torque performance in residential HVAC systems. Operating at 115V with a standard 1050 RPM rating, this ECM blower motor is a direct OEM replacement motor for several Lennox, Armstrong, and Ducane furnace models. Engineered by Genteq, it features an internal motor module that is factory-preprogrammed to match specific airflow requirements, ensuring seamless integration without the need for field programming. This 48-frame motor utilizes electronically commutated technology to provide multi-speed functionality and higher electrical efficiency compared to traditional PSC motors. For technicians performing a furnace motor replacement, the 81W36 offers a reliable solution for restoring precise static pressure compensation and consistent cubic feet per minute (CFM) delivery in units like the Lennox EL180 series.
Key Benefits- Optimized Efficiency: Features ECM technology that significantly reduces power consumption compared to standard induction motors.
- Broad Compatibility: Serving as a direct 81W36 replacement, it fits various Lennox furnaces and Allied Air equipment, including Armstrong Air and Ducane models.
- Plug-and-Play Installation: The motor comes pre-programmed with the correct torque parameters and airflow profiles for rapid deployment in the field.
- Quiet Operation: Designed to minimize vibration and audible noise during startup and high-speed operation cycles.
Is the Lennox 81W36 motor compatible with other brands?
Yes, while branded as Lennox, the 81W36 is an OEM part used across the Allied Air family, making it functionally identical for certain Armstrong Air and Ducane air handlers and furnaces.
What are the symptoms of a failing X-13 blower motor?
Technicians typically look for a failed ECM module, which often results in the motor "hunting" (rocking back and forth), intermittent operation, or a complete lack of airflow while the control board calls for fan speed.
Does this 115v 3/4HP motor require a capacitor?
No, X-13 programmed motors are brushless DC motors that do not utilize a traditional run capacitor, simplifying the electrical troubleshooting process.
