Rheem-Ruud 70-42241-01 Inducer Motor Assembly

The Rheem-Ruud 70-42241-01 Inducer Motor Assembly is a high-performance induced draft blower designed for precise flue gas evacuation in residential and light commercial gas furnaces. Engineered for 208-230V applications, this 1/20 HP shaded pole motor operates at 3300 RPM to establish the necessary static pressure for the furnace pressure switch to prove the combustion cycle. This assembly features a durable polymeric inducer housing and a left-side discharge orientation, ensuring a direct fit for many weather king furnace inducer replacements and Rheem/Ruud platforms. A critical safety component, this furnace exhaust motor includes a centrifugal switch and high-grade ball bearings for sustained quiet operation and minimal vibration during peak heating cycles. Replacing a seized or noisy 70-42241-01 with this OEM-grade assembly restores the negative pressure draft required to pull combustion gases through the heat exchanger, preventing lockout codes and ensuring efficient thermal transfer.

• Direct OEM Compatibility: Engineered as a drop-in replacement for 70-42241-01 and 7021-6967, reducing time on the job site.
• Left Discharge Configuration: Precise discharge left housing design ensures exact alignment with existing flue venting.
• Industrial Build Quality: Features ball bearings and a polymeric housing for corrosion resistance and thermal stability.
• Integrated Safety: Includes a factory-calibrated centrifugal switch to verify motor speed and airflow for the control board sequence.
• Complete Assembly: Comes as a full draft inducer assembly with gasket to ensure a gas-tight seal at the mounting plate.

Is the 70-42241-01 compatible with 115V systems?
No, this specific assembly is rated for 208-230V at 60Hz. If your system supplies 115V, verify your part number as installing this motor on a lower voltage line will lead to failure and insufficient draft.

What are the symptoms of a failing inducer motor assembly?
Common indicators include a high-pitched grinding noise (bearing wear), a furnace that hums but won't start (seized shaft/bad capacitor), or the system throwing a pressure switch lockout code because the motor cannot reach the required 3300 RPM.

Does this unit come with the mounting gasket?
Yes, this 70-42241-01 inducer motor is typically supplied with the necessary gasket (Rheem 68-21812-04 or equivalent) to ensure a proper airtight seal against the collector box.
