Nordyne 903413 Blower Assembly

The Nordyne 903413 Blower Assembly is a complete factory-spec air delivery solution designed for M1 series furnaces and gas/electric heat pump systems. Optimized for 2 to 4-ton AC capacities, this assembly features a 1/2 HP, 115V single-phase motor operating at 1075 RPM with a 4-speed configuration to handle diverse static pressure demands. The 11" x 8" direct drive Nordyne blower wheel ensures maximum cubic feet per minute (CFM) output, facilitating efficient heat exchange across the coil. As a drop-in replacement, it includes the 903433 4-speed motor, balanced blower wheel, and integrated 10 MFD run capacitor pre-mounted within a heavy-duty steel housing. This OEM Nordyne furnace part is engineered to eliminate common vibration issues and restore rated airflow to Intertherm, Miller, and Tappan HVAC units. For field technicians, the plug-and-play wiring leads simplify installation in tight cabinet clearances, ensuring reliable HVAC blower assembly performance under high-duty cycles.

• Multi-Speed Versatility: The 4-speed 1/2 HP motor allows for precise airflow adjustment to match 2-ton to 4-ton cooling requirements.
• Durable Construction: Multi-layer painted steel housing provides superior corrosion resistance in high-humidity plenum environments.
• Factory Balanced: The direct-drive 11" x 8" wheel is precision-balanced to minimize mechanical noise and bearing wear on the motor.
• Broad Compatibility: Direct fit for Nordyne M1G, M1M, M1S, M1B, and RG1 series furnaces without housing modifications.

Is this blower assembly compatible with 115V or 230V systems?
The Nordyne 903413 is strictly a 115V/60Hz component. It is designed for standard residential furnace circuits and should not be used with 230V air handlers.

Does this unit include the run capacitor?
Yes, this is a complete assembly that arrives with the motor, blower wheel, and the required 10 MFD 370V run capacitor already installed.

Can I use this for a 5-ton AC system?
This specific assembly is rated for 2 to 4-ton air conditioning capacities. For 5-ton systems, a higher-capacity blower assembly is typically required to maintain appropriate static pressure.
