This genuine OEM component is responsible for creating the negative pressure required to pull combustion air through the heat exchanger and safely exhaust flue gases out of your home. Engineered specifically for \u003cstrong\u003eGoodman, Amana, and Janitrol\u003c\/strong\u003e furnace series, this 1\/48 HP motor acts as a safety gatekeeper; it must reach full speed to close the furnace pressure switch before the ignition sequence can begin. By replacing a failing inducer with this factory-authorized assembly, you ensure your heating system maintains the precise static pressure needed for a clean, safe, and efficient burn. \u003c\/p\u003e\n\u003ch2\u003eKey Features and Function:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Combustion Airflow:\u003c\/strong\u003e Calibrated to the exact RPM and static pressure requirements of 115V Goodman cabinets to ensure reliable venting and heat transfer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine OEM Reliability\/Fitment:\u003c\/strong\u003e Designed by Goodman Manufacturing as a direct-fit replacement, ensuring the mounting holes and gasket surfaces align perfectly with the collector box.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Class B Build:\u003c\/strong\u003e Features high-grade Class B insulation and permanently lubricated bearings to withstand the high ambient temperatures of the burner compartment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect-Fit Design\/Plug-and-Play:\u003c\/strong\u003e Includes factory-terminated wiring leads for a seamless connection to the integrated furnace control board, eliminating the need for wire splicing. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Details and Key Specifications:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1859005S (Replaces B1859005, 7021-9450, 7021-10023)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Goodman \/ Amana (Genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Induced Draft Motor \/ Combustion Blower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 115V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 1.5 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHP \/ RPM:\u003c\/strong\u003e 1\/48 HP @ 3000 RPM (Nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase \/ Hertz:\u003c\/strong\u003e Single-phase (1PH) \/ 60 Hz (Note: 3-wire lead configuration)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation:\u003c\/strong\u003e Class B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 3.1 lbs \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e🛠️ HVAC Depot Pro Tip: Check for Collector Box Rust \u003c\/h2\u003e\n\u003cp\u003eBefore installing your new \u003cstrong\u003eB1859005S\u003c\/strong\u003e, inspect the plastic collector box where the motor mounts. Rust or debris from the heat exchanger often settles here and can clog the small vacuum port leading to the pressure switch. During your \u003cstrong\u003eDiagnostic Check\u003c\/strong\u003e, verify that the inducer spins freely by hand before applying power. If the motor hums but doesn't turn, it is likely seized and must be replaced to prevent blowing the 3-amp fuse on your furnace control board. Always replace the mounting gasket to prevent carbon monoxide leaks. \u003c\/p\u003e\n\u003ch2\u003eCross-Reference \u0026amp; Compatibility:\u003c\/h2\u003e\n\u003cp\u003eThe B1859005S is a direct OEM replacement for the following part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e B1859005, B18590-05, B1859000S, B1859005S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFasco \/ Aftermarket:\u003c\/strong\u003e 7021-9450, 7021-10023, 7021-10141, 7021-8735\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJakel \/ Rotom:\u003c\/strong\u003e J238-150-1533, FB-RFB590 \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eExtensive Model Compatibility List:\u003c\/h2\u003e\n\u003cp\u003eNote: Use 'CTRL+F' to search for your specific model: \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGoodman GMS8 Series:\u003c\/strong\u003e GMS80403AN, GMS80603AN, GMS80804BN, GMS81005CN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGoodman GDS8 Series:\u003c\/strong\u003e GDS80403AX, GDS80603AX, GDS80804BX, GDS81005CX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmana AMES8 Series:\u003c\/strong\u003e AMES80403AN, AMES80603AN, AMES80804BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJanitrol GMP Series:\u003c\/strong\u003e GMP050-3, GMP075-3, GMP100-3, GMP100-4, GMP125-4, GMP150-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJanitrol GDT Series:\u003c\/strong\u003e GDT050-3, GDT075-3, GDT100-4, GDT115-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMC Units:\u003c\/strong\u003e Various legacy 80% AFUE furnace configurations. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":52237843530091,"sku":"B1859005S","price":293.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/IMG-B1859005S.webp?v=1753939328","url":"https:\/\/tophvacparts.com\/products\/goodman-b1859005s-induced-draft-motor-genuine-oem-1-48-hp-115v-1-5a-class-b","provider":"HVAC Parts and Equipment Depot: Homeowners \u0026 Contractors Welcome | Plano, TX","version":"1.0","type":"link"}
