Lennox 42W47 Motor

The Lennox 42W47 is a high-performance OEM replacement blower motor engineered for precision airflow control in residential and light commercial HVAC systems. This 3/4 HP variable speed motor utilizes advanced ECM 3.0 technology to provide consistent torque and CFM delivery across varying static pressures. Operating on a dual voltage configuration of 120/240V at 50/60Hz, this Genteq constant torque motor is a direct replacement for Lennox part numbers 101564-03 and 72W43. With a nameplate speed of 1050 RPM, it integrates seamlessly with Lennox furnace and air handler control boards to optimize energy consumption and reduce operational noise. As a veteran technician knows, the integrated ECM control module is pre-programmed to handle ramping profiles, ensuring soft starts and stops that protect the blower wheel and ductwork. This 120/240v 3/4HP VAR SPD MOTOR is built for continuous air-over duty, featuring a 1/2-inch flat shaft for secure mounting in standard blower housings.

Key Benefits:
  • Precise Airflow Management: The variable speed ECM technology adjusts to system demand, maintaining optimal comfort and humidity control.
  • Dual Voltage Versatility: Compatible with both 120V and 240V power supplies, allowing for flexible installation across various equipment platforms.
  • Enhanced Efficiency: Reduces energy draw compared to traditional PSC motors, especially during partial-load conditions.
  • Universal Compatibility: Fits a broad range of Lennox, Allied, and Armstrong air handlers and furnaces requiring 3/4 HP output.
Common Questions:
  • Is the control module included? Yes, this is a complete 42W47 motor and module assembly, pre-programmed for immediate installation into compatible Lennox units.
  • What causes premature failure in these motors? Most ECM motor failures are caused by excessive static pressure or power surges; we recommend inspecting the blower wheel and installing an inline surge protector during replacement.
  • Can I use this to replace a 1/2 HP motor? No, you must match the horsepower and frame specifications 1:1 with the original OEM motor to prevent damage to the control board or blower assembly.
