Lennox 98G42 Inducer Motor Assembly

The 98G42 Inducer Motor Assembly is a factory-authorized Lennox 98G42 part engineered for high-efficiency draft induction in gas heating systems. This 1/10 HP, 208-230V furnace inducer motor replacement is a critical safety component designed to clear the heat exchanger of combustion gases before ignition and during the heating cycle. Utilizing a PSC motor design with a high-speed rating of 3300 RPM, it ensures consistent static pressure to keep internal safety switches engaged. This specific assembly is officially classified as a 1-phase HVAC draft inducer assembly and is commonly used in commercial and residential series like the GCS16 and GCS24. Technical field data confirms that the 98G42 is functionally 100% identical to the 98G4201, allowing for seamless integration without modifications to the existing mounting brackets or duct transitions.

Key Benefits:

• Direct OEM Fit: Replaces Lennox 98G4201 and other legacy Lennox furnace parts with zero gap at the collector box interface.
• Optimized Performance: Operates at 0.5 Amps and 60Hz, maintaining a counterclockwise (CCWLE) rotation for precise airflow management.
• Heavy-Duty Construction: Features sealed ball bearings and a thermally protected motor housing to withstand the high-temperature environment of an active flue system.
• Complete Assembly: Includes a factory-matched 2 MFD, 370 VAC capacitor to ensure high starting torque and efficient operational cycles.

Common Questions:

What are the signs that my current inducer motor is failing?
Technicians typically look for a loud buzzing or mechanical grinding noise upon startup. If the pressure switch fails to stay closed despite a clear flue, the motor may not be reaching its 3300 RPM threshold due to bearing resistance or windings degradation.

Is the 98G42 compatible with both 208V and 230V systems?
Yes, this assembly is rated for a 208-230V range, making it suitable for standard single-phase residential and commercial applications where Lennox equipment is installed.

Do I need to replace the gasket when installing this motor?
While the 98G42 is a drop-in replacement, it is professional best practice to inspect the existing seal. Any degradation in the gasket can cause air leaks, leading to erratic pressure switch readings and furnace lockout.
