Fasco D1190 Motor
When you're on a service call for a failing draft inducer, the Fasco D1190 Motor is the industry-standard OEM replacement motor for Weil-McLain furnace systems and flue exhaust applications. This 1/30 HP unit is purpose-built to handle the high-static pressure demands of modern combustion cycles. Operating at a high-speed 3300 RPM with a 115V single-phase shaded pole design, this 3.3-inch diameter motor delivers consistent torque to ensure proper venting of combustion gases. The D1190 features a 5/16" x 1-3/4" shaft with a flat, designed specifically for a secure fit on blower wheels. It utilizes sleeve bearings for quiet operation and is thermally protected to prevent winding failure during extended run times. Its clockwise (CW) rotation and lug mounting configuration match original equipment specifications exactly, allowing for a drop-in installation that restores system pressure switch levels and prevents nuisance lockouts. For technicians, this direct replacement motor eliminates the guesswork of universal fitments, ensuring the flue exhaust operates within the manufacturer's specified CFM range.
Key Benefits for HVACR Technicians:
- Direct OEM Compatibility: Engineered as a drop-in replacement for Weil-McLain 7121-5750 and JA1N074, ensuring all mounting lugs and shaft dimensions align perfectly.
- High-Speed Performance: The 3300 RPM output provides the necessary static pressure to reliably close the draft prover switch and maintain safe flue velocities.
- Robust Construction: Features Class B insulation and a 40°C max ambient temperature rating, essential for the high-heat environment of a furnace cabinet.
- Reliable Starting: Shaded pole technology provides consistent starting torque without the need for external capacitors, simplifying the electrical troubleshooting process.
- Optimized Duty Cycle: Rated for Open Air Over (OAO) duty, utilizing the airstream for cooling to ensure long-term performance in draft booster applications.
Common Questions & Support:
- Does the Fasco D1190 replace Dayton 48GN78? Yes, the Fasco D1190 is a confirmed cross-reference for the Dayton 48GN78, as well as multiple Weil-McLain furnace inducer numbers.
- How do I verify the rotation? This motor is Clockwise (CW) rotation when viewed from the shaft end. Always verify rotation before mounting the blower wheel to avoid back-venting risks.
- What is the shaft size for wheel compatibility? The motor features a 5/16-inch diameter shaft with a flat side, which is standard for most 3.3" frame draft inducer wheels.
