Nordyne 901838 Motor

When you're out on a service call and find a failed blower, the Nordyne 901838 motor is the standard OEM replacement you need to get Intertherm, Miller, and Nordyne furnaces back in operation. As a 1/3 HP, 240V single-phase unit, this PSC blower motor is engineered for a 1050 RPM nominal speed, featuring a 4-speed tap configuration that allows for precise airflow balancing across heating and cooling cycles. This motor, which replaces the obsolete Genteq 5KCP39GGF654AS, features a standard 1/2-inch shaft and a rolled steel frame for heat dissipation. For a clean installation, verify your 7.5 MFD / 370V run capacitor, as a weak cap is a leading cause of premature winding failure. This direct drive blower motor includes the necessary plug harness to maintain the original molex connections, ensuring you aren't wasting time with field-splicing in tight closets.

• OEM Compatibility: Direct replacement for Nordyne part number 1050862 and various Intertherm furnace blower motors.
• Multi-Speed Versatility: 4-speed taps (High, Med-High, Med-Low, Low) provide flexibility for matching specific CFM requirements.
• Simplified Wiring: Equipped with a factory-integrated plug harness for a drop-in HVAC motor replacement.
• Reliable Construction: Built with an aluminum flange and rugged frame to handle high-static environments.

Is this a direct replacement for my older 2-speed motor?
Yes, the Nordyne 901838 can replace older 2-speed models. Ensure you cap off any unused speed taps and verify that the 240V single-phase motor wiring matches your control board's output.

Does this motor require a specific capacitor?
Technicians should always replace the run capacitor when installing a new motor. This unit typically requires a 7.5 MFD / 370VAC capacitor to ensure proper torque and amperage draw.

What causes this motor to hum but not start?
Check the run capacitor first. If the capacitor is within tolerance, check the blower wheel for obstructions or seized bearings. If the wheel spins freely by hand but the motor only hums under power, the internal windings are likely compromised.
