Carrier 310371-752 Assembly

The Carrier 310371-752 Inducer Motor Assembly is a critical OEM replacement component designed for high-efficiency draft induction in Carrier and Bryant residential furnaces. This 115V single-phase assembly features a high-torque shaded pole motor rated at approximately 3,300 RPM (full load 1.8A) to ensure optimal combustion airflow. Built for direct-drive reliability, this unit facilitates the safe expulsion of flue gases from the heat exchanger before the ignition cycle begins. The assembly comes pre-configured with the inducer housing, motor, and integrated wheel, eliminating the need for complex field balancing or alignment. It acts as a direct drop-in for worn-out draft inducer blowers in models such as the 375A series, frequently replacing legacy part numbers including 310371-751 and HC23UE121. For contractors performing preventative maintenance or emergency repairs, this factory-authorized part ensures technical compatibility with the existing wire harness and furnace pressure switch pneumatic connections, maintaining the factory-specified performance of the heating system.

Key Benefits

• Direct OEM Compatibility: Engineered specifically for Carrier and Bryant systems to match the original factory specifications for static pressure and airflow.
• Streamlined Installation: Features a quick-connect wire harness and includes necessary gaskets to prevent flue gas leakage at the collector box seal.
• Optimized Performance: The 3,300 RPM motor ensures consistent drafting, preventing pressure switch lockout codes and improving overall heat exchanger efficiency.
• Comprehensive Assembly: Includes the blower wheel and motor pre-mounted to the bracket, reducing field labor time and minimizing the risk of vibration issues.

Common Questions

• Will this assembly fix a 'Pressure Switch Did Not Close' error code? Yes, if the existing motor is failing to reach target RPM or the wheel is obstructed, this 310371-752 assembly provides the necessary draft to close the pressure switch and initiate the heating cycle.
• Is any additional hardware required for mounting? This unit is an integrated assembly that mounts directly to the collector box; however, technicians should always inspect the collector box gasket during replacement.
• Does this motor require a separate capacitor? No, this is a shaded pole motor design that does not utilize a separate run capacitor, simplifying the electrical troubleshooting process.
