Rated at 1\/100 HP, 115 volts, and 0.69 amps, it draws 37.25 watts and spins at 3000 RPM single speed. The skeleton motor construction uses a ball bearing design for reliable rotation under continuous-duty thermal cycling. A two-prong Molex plug is attached at the factory, and the motor is thermally protected. Licensed HVAC technicians replace this component when inducer motor failure prevents the furnace from completing its ignition sequence.\u003c\/p\u003e\n\u003cp\u003eThis motor fits Nordyne-manufactured furnace platforms sold under multiple brand labels. Compatible brand names documented in the manufacturer data include Broan, Frigidaire, Gibson, Intertherm, Mammoth, Maytag, Miller, Nutone, Reznor, and Westinghouse. It is a direct OEM-replacement style unit intended for residential gas furnace draft inducer assemblies. The 4-inch blade configuration installs one blade on each side of the motor, and the 7\/8-inch stack dimension is relevant for verifying physical fitment before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eShaded-pole skeleton motor rated 1\/100 HP at 115 volts, 3000 RPM\u003c\/li\u003e\n  \u003cli\u003eBall bearing construction for extended service life under heat and vibration\u003c\/li\u003e\n  \u003cli\u003eFactory-attached two-prong Molex plug for direct wiring connection\u003c\/li\u003e\n  \u003cli\u003eThermal overload protection built in to prevent motor burnout\u003c\/li\u003e\n  \u003cli\u003e4-inch blades (one on each side) matched to Nordyne inducer housing dimensions\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch stack height for physical fitment verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDirect replacement for Nordyne-manufactured furnace models sold under the Broan, Frigidaire, Gibson, Intertherm, Mammoth, Maytag, Miller, Nutone, Reznor, and Westinghouse brand names.

Shut off power at the disconnect and shut off the gas supply before removing the inducer assembly. Verify that the replacement motor stack height and blade diameter match the original before securing the assembly, as improper fitment will affect combustion airflow. Follow local mechanical codes and the furnace manufacturer service instructions when reinstalling the inducer housing and reconnecting the Molex plug.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Shaded Pole Skeleton Motor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 1\/100 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 0.69 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e: 37.25 watts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: 3000 RPM, Single Speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Diameter\u003c\/strong\u003e: 4 inches (one blade on each side)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStack Height\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball Bearing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector\u003c\/strong\u003e: Two-Prong Molex Plug, Factory Attached\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Protection\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.98 inches x 5.98 inches x 5.98 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Supco\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SM3404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HEATINGVARIOUSMFG-GENERIC","offers":[{"title":"Default Title","offer_id":51994930446642,"sku":"SM3404","price":120.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6aff12f3c7eddd14d8a3d05df7632df.jpg?v=1789992271","url":"https:\/\/voomisupply.com\/products\/supco-sm3404-draft-inducer-fan-motor-replaces-903404","provider":"Voomi Supply","version":"1.0","type":"link"}
