Carrier 319828-701 Wheel Assembly

For service technicians handling combustion air issues, the Carrier 319828-701 Wheel Assembly is the factory-authorized OEM solution for restoring proper pressure switch circuit operation. This 9-inch draft inducer blower wheel features a 5/16-inch bore and is precision-balanced to eliminate harmonic vibrations that can lead to premature motor bearing failure. Engineered for high-temperature furnace environments, this inducer wheel assembly maintains a consistent flue-venting draft, ensuring efficient combustion across Carrier, Bryant, and Payne models, including the 58MCA series.

When diagnosing a furnace that is failing to prove the inducer pressure switch, check for cracked fins or debris imbalance on the existing combustion inducer wheel. Replacing a damaged wheel with this genuine Carrier furnace part ensures an exact fit and restores the original CFM specifications required for safe exhaust gas removal. The durable plastic construction is specifically designed to resist the corrosive condensate found in high-efficiency heating systems.

• OEM Precision: Correct 9" diameter and 5/16" bore ensures a direct fit without shaft modifications.
• Vibration Reduction: Factory balancing prevents noise and extends the service life of the inducer motor.
• Optimized Airflow: Engineered blade pitch maintains the static pressure required for safe furnace ignition.
• Broad Compatibility: Replaces part numbers 319828-401, 319828-402, and 326547-401 in various residential units.

Is the set screw included with this assembly?
This assembly is typically supplied with the necessary hub components; however, it is standard practice to inspect the motor shaft for scoring before tightening the set screw to the required torque specifications found in the service literature.

Will this wheel resolve a whistling or rattling noise in the draft inducer?
Yes, those symptoms are often caused by a warped or unbalanced blower wheel. Replacing the assembly restores whisper-quiet operation and prevents lateral stress on the motor shaft.

What furnace models use this part?
This wheel is commonly found in the 58MCA, 58MXA, and 58MCB Carrier furnace lines, as well as equivalent Bryant and Payne crossover models.
