Carrier 305247-402 Housing

The Carrier 305247-402 Housing is a critical OEM draft inducer motor housing designed specifically for maintaining the structural integrity of the combustion assembly in Carrier, Bryant, and Payne gas furnaces. This factory-authorized component serves as the precise enclosure for the inducer blower wheel, ensuring optimal static pressure and exhaust gas flow within the venting system. Constructed to exact BDP specifications, the 305247-402 facilitates proper pressure switch activation by preventing air leaks and managing condensate drainage effectively. When servicing condensing furnaces, replacing a cracked or warped collector box or inducer housing with this genuine HVAC furnace replacement part is essential for preventing safety lockouts related to poor flue gas drafting.

• Direct OEM Fitment: Ensures seamless bolt-on alignment with existing motor mounts and flue pipes without field modifications.
• High-Temperature Durability: Engineered with composite materials designed to withstand cyclical thermal stress and acidic condensate exposure.
• Optimized Airflow: Precision-molded interior volute geometry maximizes induced draft blower efficiency and reduces vibration.
• System Safety: Restores factory-spec static pressure readings to ensure reliable operation of the furnace pressure switch.

Common Installation Questions

Is the 305247-402 compatible with high-efficiency condensing units?
Yes, this housing is specifically engineered for the secondary heat exchanger systems found in 90% AFUE and higher gas furnaces where moisture management is critical.

Does this housing include the blower wheel or motor?
No, this is the inducer housing only. If the motor or wheel is damaged, those components must be salvaged from the existing assembly or sourced separately for a complete vent motor repair.

Why is my furnace pressure switch not closing with the old housing?
Cracks in the housing or clogs in the integrated pressure ports are common failure points. Replacing the Carrier furnace inducer housing restores the vacuum signal required to close the safety circuit.
