Product Details

The Lennox 74W56 (Model LB-94724AB) is a genuine OEM combustion air blower assembly designed for Lennox, Armstrong, and Ducane gas furnaces. This critical component draws combustion air into the burner and safely exhausts flue gases through the venting system, ensuring proper furnace operation and preventing heating failures.

Key Specifications:

  • Motor Power: 1/40 HP
  • Operating Speed: 3250 RPM
  • Voltage: 120V AC, 60 Hz
  • Housing: Metal construction for durability
  • Single stage operation
  • Clockwise rotation (lead end viewing)

This draft inducer motor assembly is essential for maintaining safe and efficient combustion in your furnace. If your furnace fails to ignite, shuts down prematurely, or displays venting-related error codes, a faulty inducer motor may be the cause. The 74W56 provides reliable performance and is designed to meet Lennox's exacting quality standards for residential HVAC applications.
