The Goodman B1376853 Blower Motor Mount Arm is a genuine OEM replacement bracket engineered for AEPF426016AA air handlers. This stamped-steel arm secures the blower motor to the housing assembly, maintaining proper shaft alignment and dampening vibration so the blower wheel spins true and quiet. A worn, cracked, or corroded mount arm is a common cause of rattling, blower noise, and premature motor bearing failure — replacing it restores factory-spec support.
This is a genuine Goodman OEM part built to the exact dimensions and bolt pattern of the original. Generic or universal brackets often require drilling or shimming and can introduce misalignment that shortens motor life. The OEM arm bolts in directly with no modification.
Moderate — requires removing the blower assembly to access the mount. A nut driver and basic hand tools are sufficient; allow 30–45 minutes. Always disconnect power before servicing.
