Carrier 320725-756 Draft Inducer Assembly

For service technicians managing mid-efficiency Carrier, Bryant, or Payne gas furnaces, the Carrier 320725-756 Draft Inducer Assembly is a factory-specified replacement designed to restore proper venting and pressure switch circuit closure. This 115 V draft inducer motor features a 1/16 Horsepower permanent split capacitor (PSC) motor rated for 3300 RPM and 1.02 Amps. As a complete OEM draft inducer assembly, it includes the precisions-balanced blower wheel, plastic housing, and internal cooling fan, facilitating a fast drop-in installation compared to a motor-only swap. It is frequently employed in 40,000 to 100,000 BTU models to resolve common issues like furnace pressure switch faults, 31/32 code lockouts, and noisy inducer bearings. This heavy-duty furnace inducer blower is cross-compatible with several legacy part numbers, including 320725-751, 320725-752, and HC28CQ116. Proper installation ensures the furnace effectively evacuates combustion gases, maintaining the safe, high-performance operation required in HVAC ventilation systems.

• Precision Performance: The 1/16 HP motor is engineered for a consistent 3,300 RPM, providing the exact static pressure required to close the furnace pressure switch.
• OEM Compatibility: Replaces multiple previous versions including 320725-751 and HC27CB115, ensuring a direct mechanical fit without field modifications.
• Complete Kit: Features a factory-assembled housing and blower wheel, reducing labor time and eliminating the risks associated with reusing worn wheel components.
• Durable Construction: Built with a thermally protected motor and industrial-grade housing for reliable operation in high-heat environments.

Common Questions

Does this assembly include the necessary capacitor?
Yes, this 115V assembly comes with a pre-wired 3 MFD capacitor and the standard 5-wire harness used in compatible furnace models.

Will this resolve a furnace code 31 lockout?
A code 31 usually indicates a pressure switch did not close. If the existing inducer is drawing high amps, running slow, or has physical obstruction, replacing it with the Carrier 320725-756 often corrects the draft issue.

Is this inducer assembly compatible with high-efficiency condensing furnaces?
This specific unit is typically used in mid-efficiency (80% AFUE) induction-draft furnaces. Always verify your specific furnace model number against the factory parts list before installation.
