The B1376853 is a genuine Goodman/Amana OEM fan motor mount arm engineered for the APH1642H41AA package heat pump. This stamped-steel support arm secures the condenser fan motor to the unit's top panel, holding the motor in precise alignment so the fan blade clears the shroud and the bearings run true. A bent, corroded, or fatigued mount arm is a common cause of fan wobble, rubbing, and premature motor failure — replacing it during any fan or motor service restores factory geometry.
This is a factory-original Goodman part with the exact bolt pattern, arm length, and offset the APH1642H41AA was built around. Generic or universal brackets often require drilling new holes or shimming, which throws off blade clearance and can void motor warranties. The OEM arm drops in with no modification.
Easy (1/5). A basic hand-tool job — disconnect power, remove the fan grille and old arm, transfer the motor, and reinstall. No electrical or refrigerant work required. Most techs and handy homeowners complete it in under 20 minutes.
Always disconnect power at the disconnect and breaker before servicing. If you are unsure of the part fit, contact us with your full unit model and serial number.
