The Goodman B1376857 Fan Motor Mount Arm is the OEM condenser fan-motor support bracket for APH1436M41AA packaged heat pumps and compatible 3-ton APH1436-series units. It secures the fan motor over the top-discharge condenser fan, holding the motor and blade in correct alignment within the orifice to minimize vibration, noise, and premature bearing wear.
This genuine OEM arm matches the factory motor bolt pattern and cabinet standoff locations exactly. Universal aftermarket brackets are cheaper but typically need field drilling and can throw off the factory blade-to-orifice depth. For an exact, rattle-free repair, the OEM part is the reliable choice.
Easy (1/5). Disconnect power, support the motor, transfer it to the new arm, and re-bolt. Hand tools only, roughly a 15–20 minute job. Verify fan-blade clearance in the orifice before restoring power.
Fitment note: confirm your model/serial before ordering. This is a mechanical bracket with no MFD/amp/HP rating.
