The mount arm holds the fan motor in correct position over the condenser coil, keeping the blade centered in the orifice and free of vibration. Over time these arms can fatigue, bend, or rust — leading to motor wobble, blade rub, and excess noise. Replacing the arm with the factory part restores proper alignment and protects the motor and blade.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1376857\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eComponent: Condenser fan motor mount arm \/ bracket\u003c\/li\u003e\n\u003cli\u003eFits Model: WGPH4549AMAB packaged unit\u003c\/li\u003e\n\u003cli\u003eMaterial: Coated\/galvanized steel\u003c\/li\u003e\n\u003cli\u003eMounting: Factory hole pattern — direct fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e mount arm matches the original length, bend geometry, and bolt spacing, so the motor sits at the correct height and the blade stays centered. Universal brackets often require field bending or re-drilling to position the motor, which risks misalignment and vibration. For a low-cost structural part, OEM fit saves time and avoids rework.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate\u003c\/strong\u003e — disconnect power, support the fan motor, unbolt the old arm, install the new arm, and re-mount the motor. About 20–30 minutes with basic hand tools. No refrigerant or wiring changes required, though motor alignment should be checked before restart.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057216242035,"sku":"GOODMAN-1057","price":9.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-motor-mount-arm-for-wgph4549amab-b1376857-1","provider":"National HVAC Parts","version":"1.0","type":"link"}
