Reznor 257461 Inducer Motor

The Reznor 257461 Inducer Motor is an essential OEM replacement component engineered for high-static combustion environments in commercial gas-fired unit heaters. This 1/3 HP venter motor operates at 208/230V, 60Hz, and single-phase power, delivering a consistent 3450 RPM to maintain the precise pressure differential required for safe burner ignition and flue gas evacuation. Designed with an Open Drip Proof (ODP) enclosure, this motor manages internal heat dissipation effectively during continuous duty cycles, ensuring the draft fan pulls air through the heat exchanger without stalling or RPM fluctuations.

When diagnosing Reznor HVAC equipment, a failing inducer often presents as a pressure switch fault or excessive vibration. The Reznor 257461 features a precision-balanced rotor and heavy-duty bearings to minimize harmonic noise and mechanical wear. As a genuine Reznor part, it ensures direct "drop-in" compatibility for models requiring a high-RPM induced draft motor, eliminating the mounting and wiring adjustments common with universal alternatives. This motor is typically used in larger Reznor units where airflow volume is critical for efficient thermal transfer and venting integrity.

• OEM Performance: Engineered specifically for Reznor unit heaters to match factory airflow and pressure specifications.
• High-Efficiency Combustion: Maintains 3450 RPM for stable flame signals and proper draft through the heat exchanger.
• Durable ODP Construction: Specifically built for commercial heating applications to withstand ambient temperature shifts.
• Simplified Installation: Direct-fit bolt pattern and electrical terminations reduce labor time for field service technicians.

Common Questions

What are the electrical requirements for the Reznor 257461?
This motor is rated for 208/230V, 60Hz, 1-phase operation. Ensure your supply voltage matches the motor nameplate to prevent winding burnout.

Can I use this motor to replace a 115V inducer?
No. The Reznor 257461 is a 230V component. Installing it on a 115V circuit will result in insufficient torque and motor failure. Always verify the voltage of the existing venter assembly before replacement.

Does this assembly include the blower wheel?
This specific part number refers to the 1/3 HP motor. It is standard practice to inspect the existing blower wheel for corrosion or imbalance when swapping the draft inducer motor.
