Lennox 74W56 Inducer Assembly
The Lennox 74W56 Inducer Assembly is a critical OEM replacement part engineered for high-efficiency combustion air venting in specific residential gas furnaces. This assembly features a robust induced draft motor designed to facilitate the safe expulsion of flue gases through the heat exchanger, ensuring the system clears the pressure switch safety circuit during the ignition sequence. Operating at 120 volts and a high-speed rating of 3250 RPM, this Fasco 70581871 styled unit provides the necessary static pressure for 80% efficiency single-stage and two-stage downflow units. For technicians, this 74W56 furnace inducer is the direct solution for seized bearings, open windings, or failed exhaust blower wheels that result in system lockouts. The kit typically includes the necessary gasket material to maintain a gastight seal between the inducer housing and the collector box, preventing dangerous CO leakage into the cabinet. This high-performance draft inducer kit is essential for maintaining the operational integrity and AFUE ratings of compatible Lennox, Armstrong, and Ducane equipment.
Key Benefits:- Precision Engineering: Designed as a direct OEM replacement to ensure exact mounting alignment and electrical connector compatibility with the SureLight control board.
- Optimal Airflow: High-RPM output effectively purges the heat exchanger of combustion byproducts, preventing soot buildup and erratic pressure switch trips.
- Enhanced Durability: Features heavy-duty internal components built to withstand the high-heat cycles of downflow furnace configurations.
- Complete Assembly: Includes the blower wheel and motor housing, reducing installation time and ensuring the entire exhaust path is refreshed.
- Will this part fix a 'Pressure Switch Stuck Open' error? If the inducer motor fails to reach the required RPM or the wheel is damaged, it won't create enough vacuum to close the switch. This assembly is the primary fix for such mechanical failures.
- Does the kit include the mounting gasket? Yes, usually a new gasket is provided to ensure a proper seal against the flue collector box, which is a requirement for safe operation.
- Is this compatible with upflow models? This specific part number (74W56) is typically specked for downflow (DF) units; always verify your specific model number against the factory parts list.
