This Original Equipment Manufacturer (OEM) motor functions as the primary driver for the indoor blower wheel. It pulls return air through your filter system and pushes conditioned air across the heat exchanger or evaporator coil and into your home's ductwork. Engineered specifically for Trane and American Standard furnaces and air handlers, this motor offers a multi-speed design that allows the system's control board to manage correct airflow cubic feet per minute (CFM) for both heating and cooling modes.\u003c\/p\u003e\n\u003ch2 class=\"MsoNormal\"\u003eKey Features:\u003c\/h2\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cbr\u003e• \u003cb\u003eFour-Speed Airflow Management:\u003c\/b\u003e Features a versatile 4-speed design that allows customized performance based on system demands, delivering balanced airflow and optimized noise levels.\u003cbr\u003e• \u003cb\u003eGenuine OEM Precision Fit:\u003c\/b\u003e Engineered as a direct mechanical drop-in for 48-frame blower assemblies, part number \u003cb\u003eMOT18949\u003c\/b\u003e ensures factory alignment without modifying bracket bands.\u003cbr\u003e• \u003cb\u003eNoise Reduction Design:\u003c\/b\u003e Operates at a standard 1075 RPM, specifically engineered to minimize operational air rush and fix the \"rushing wind\" or clicking relay noises common in older single-speed motors.\u003cbr\u003e• \u003cb\u003eAutomatic Thermal Overload:\u003c\/b\u003e Includes an internal thermal protector that safely shuts off the motor in case of overheating or restricted airflow, defending the sensitive windings from burnout.\u003cbr\u003e• \u003cb\u003eHeavy-Duty Construction:\u003c\/b\u003e Built with premium insulated windings and a robust housing to withstand continuous air-over duty in demanding residential environments.\u003c\/p\u003e\n\u003ch2 class=\"MsoNormal\"\u003eProduct Details:\u003c\/h2\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cbr\u003e• \u003cb\u003ePart Number:\u003c\/b\u003e MOT18949\u003cbr\u003e• \u003cb\u003eManufacturer:\u003c\/b\u003e Trane \/ American Standard (Genuine OEM)\u003cbr\u003e• \u003cb\u003ePart Type:\u003c\/b\u003e PSC Blower Motor\u003cbr\u003e• \u003cb\u003eVoltage:\u003c\/b\u003e 115V \/ 60 Hz\u003cbr\u003e• \u003cb\u003eHP \/ RPM:\u003c\/b\u003e 1\/2 HP \/ 1075 RPM\u003cbr\u003e• \u003cb\u003ePhase \/ Hertz:\u003c\/b\u003e Single-phase (1PH) \/ 60 Hz\u003cbr\u003e• \u003cb\u003eRotation:\u003c\/b\u003e Reversible (CW\/CCW) or CCW Lead End\u003cbr\u003e• \u003cb\u003eBore \/ Shaft:\u003c\/b\u003e 1\/2\" Diameter x 3.5\" Length\u003cbr\u003e• \u003cb\u003eShipping Weight:\u003c\/b\u003e Approx. 15.2 lbs\u003c\/p\u003e\n\u003ch2 class=\"MsoNormal\"\u003e\n\u003cspan style=\"font-family: 'Segoe UI Emoji',sans-serif; mso-bidi-font-family: 'Segoe UI Emoji';\"\u003e🛠️\u003c\/span\u003e HVAC Depot Pro Tip: Don't Forget the Capacitor!\u003c\/h2\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cbr\u003eWhen upgrading or replacing a PSC motor like the \u003cb\u003eMOT18949\u003c\/b\u003e, it is standard professional practice to replace the run capacitor at the exact same time. This motor typically requires a 5 MFD or 15 MFD run capacitor (verify your specific chassis plate). Operating a brand-new motor with an old, weak capacitor will cause it to run hotter than designed, significantly shortening the motor's operational life and voiding manufacturer coverage.\u003c\/p\u003e\n\u003ch2 class=\"MsoNormal\"\u003eCross-Reference \u0026amp; Compatibility:\u003c\/h2\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cbr\u003eThe MOT18949 is a direct OEM replacement for the following part numbers:\u003cbr\u003e• \u003cb\u003eOEM Numbers:\u003c\/b\u003e MOT08537, MOT11992, X70377592001\u003cbr\u003e• \u003cb\u003eProduction Numbers:\u003c\/b\u003e D340988P02, K55HXHKL-8719\u003cbr\u003e• \u003cb\u003eAftermarket Equivalent:\u003c\/b\u003e Emerson Model K55HXHKL-8719\u003c\/p\u003e\n\u003ch2 class=\"MsoNormal\"\u003eExtensive Model Compatibility List:\u003c\/h2\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cbr\u003e• \u003cb\u003eGas Furnaces:\u003c\/b\u003e ADC100C948B8, TUD120C954K1, TUD080, TUD100\u003cbr\u003e• \u003cb\u003eAir Handler Series:\u003c\/b\u003e TWE030, TWE036, TWE042\u003cbr\u003e• \u003cb\u003eAmerican Standard Equivalent:\u003c\/b\u003e Models requiring 1\/2 HP 115V 4-speed 48-frame motors\u003c\/p\u003e","brand":"Trane","offers":[{"title":"Default Title","offer_id":52229806457195,"sku":"MOT18949","price":444.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/MOT18949-2.jpg?v=1774971956","url":"https:\/\/tophvacparts.com\/products\/trane-mot18949-genuine-oem-1-2-hp-4-speed-blower-motor-115v-1075-rpm","provider":"HVAC Parts and Equipment Depot","version":"1.0","type":"link"}
