Lennox 11K98 Inducer Assembly

The Lennox 11K98 Inducer Assembly is a critical OEM replacement component designed for high-efficiency gas furnaces. This combustion blower kit includes the 11K9801 inducer motor and an integrated pressure switch kit, ensuring precise air pressure monitoring for safe ignition sequences. As a direct replacement for legacy part numbers like 68M93 and 100445-01, this assembly facilitates the removal of flue gases through the heat exchanger, maintaining the correct static pressure required by the ignition control board. The ball-bearing motor construction provides reliable operation under high thermal loads, preventing common furnace inducer motor noise or bearing failure. Whether you are performing a Lennox furnace repair or a preventative system overhaul, this assembly ensures the draft inducer meets the original equipment specifications for CFM output and electrical draw. Proper installation of this Lennox draft inducer is essential for resolving pressure switch lockout codes and restoring optimal furnace performance during peak heating cycles.
