The blower wheel is the heart of your air handler's airflow system — it pulls conditioned air across the coil and pushes it through your duct system. A cracked, warped, or out-of-balance wheel causes weak airflow, vibration, rattling, and uneven room temperatures, so replacing it with a precision-balanced OEM wheel restores quiet, efficient operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWheel diameter x width: 9 in. x 6 in.\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1368042S\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana compatible)\u003c\/li\u003e\n\u003cli\u003eEquipment: Air Handler\u003c\/li\u003e\n\u003cli\u003eFits Model: WAHMS1931P4ACA\u003c\/li\u003e\n\u003cli\u003eMaterial: Galvanized steel, factory-balanced\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the genuine OEM B1368042S. Because blower wheels are dimensionally and rotationally matched to the housing and motor shaft, an OEM wheel guarantees correct bore size, balance, and CFM output. Aftermarket wheels are rare for this size and often arrive unbalanced, leading to premature motor-bearing wear. We recommend OEM for blower-wheel replacements.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires removing the blower assembly, loosening the set screw on the motor shaft, and re-seating the new wheel flush with the shaft. Always disconnect power first. Most experienced DIYers complete this in 45–60 minutes; if you are unsure, a licensed HVAC technician can install it quickly.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Direct Replacement","offer_id":63032422465907,"sku":"B1368042S-GEN","price":34.95,"currency_code":"USD","in_stock":true},{"title":"OEM","offer_id":63048175780211,"sku":"B1368042S","price":45.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-blower-wheel-B1368042S_99c6cf47-8e66-4a6f-a873-9ba1556c469f.jpg?v=1782946177","url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-9-x-6-in-blower-wheel-for-wahms1931p4aca-b1368042s","provider":"National HVAC Parts","version":"1.0","type":"link"}
