Lennox 19J04 Inducer Assembly

The Lennox 19J04 Inducer Assembly is a high-performance shaded pole motor designed for critical venting in HVAC systems. Engineered for precision, this draft inducer assembly features a 1/65 HP motor operating at 3000 RPM on 115/120V, 60Hz power. As a direct replacement for Lennox 19J0401, it ensures seamless integration with models such as the LF24-150S-1 and LD24 series. The unit facilitates the mechanical draft necessary to purge heat exchangers of combustion gases, optimizing furnace efficiency and ensuring the pressure switch closes reliably for consistent ignition cycles. Built with durable metal housing and thermally protected windings, this assembly is the standard choice for contractors looking to resolve common furnace draft blower failures, loud bearing noise, or venting issues in residential and commercial Lennox units.

Key Benefits:

• Exact Compatibility: Replaces Lennox 19J04 and 19J0401, maintaining OEM performance levels.
• Enhanced Safety: High-velocity 3000 RPM draft motor effectively clears combustion byproducts through the flue.
• Durable Construction: Shaded-pole design with thermal protection prevents motor burnout in high-heat environments.
• Quiet Operation: Precision-balanced blower wheel reduces vibration and mechanical noise compared to worn aftermarket alternatives.

Common Questions:

Is the 19J04 identical to the 19J0401?
Yes, these part numbers are interchangeable. The 19J04 is the contemporary designation for the earlier 19J0401 assembly, featuring the same mounting footprint and electrical specifications.

What are the symptoms of a failing Lennox inducer assembly?
Technicians typically look for a "grinding" sound indicative of bearing failure, a "humming" motor that fails to spin, or a system lockout where the pressure switch fails to close due to inadequate draft.

Does this assembly include the gasket?
While the assembly is ready for installation, we recommend checking the existing collector box gasket. If it is brittle or cracked, use a new gasket or high-temperature silicone to ensure a gastight seal during replacement.
