The Goodman B1376853 Motor Mount Arm is a genuine OEM structural bracket engineered for the APH1436H41DB Amana/Goodman package heat pump. This arm secures the motor assembly to the unit frame, holding critical alignment between the motor shaft and blower wheel or condenser fan. A worn, cracked, or corroded mount arm causes vibration, noise, and premature bearing wear — replacing it restores factory-spec support and quiet operation.
The OEM B1376853 matches the factory bolt pattern, gauge thickness, and vibration-damping geometry exactly, so the motor sits in its designed position with no re-drilling. Generic universal brackets often require field modification and can shift motor alignment, leading to belt/wheel rub and warranty-voiding stress on the motor. For a direct, no-guesswork repair, the OEM part is the safe choice.
Easy (1/5). Disconnect power, unbolt the motor from the old arm, swap the bracket, and re-torque. Typically a 15–20 minute job with basic hand tools. Always confirm power is off at the disconnect before servicing.
Fits Goodman/Amana APH1436H41DB. Verify your unit's model and serial before ordering. Questions? Contact info@nationalhvacparts.com.
