Carrier 48TJ400431 Inducer Housing

The Carrier 48TJ400431 Inducer Housing is a critical OEM replacement component designed for high-performance gas-fired rooftop units. Engineered for precise fitment within the Carrier 48TJ series, this draft inducer blower housing manages combustion air flow and ensures the safe evacuation of flue gases. Use this heavy-duty housing to resolve issues related to vent motor vibration, housing cracks, or airflow restrictions that trigger pressure switch faults. Constructed from high-grade materials to withstand consistent thermal cycling, it maintains structural integrity under the high static pressures characteristic of commercial HVAC systems. Replacing a compromised housing is essential for maintaining AFUE ratings and preventing incomplete combustion. When performing a venter motor assembly repair, verifying the integrity of this housing ensures the blower wheel operates with minimal run-out, extending the service life of the motor and internal gaskets.

• OEM Compatibility: Direct-fit replacement for specified Carrier, Bryant, and Payne 48TJ gas/electric packaged units.
• Durable Construction: Engineered to resist warping and corrosion from acidic flue gas condensates.
• Optimized Airflow: Precision-molded internal geometry reduces turbulence for stable pressure switch readings.
• Simplified Installation: Standardized mounting points allow for rapid field replacement, reducing labor hours on the job site.

• Can I use this housing for different 48-series tonnages? While designed for the 48TJ line, always verify the specific model number and series version, as housing dimensions vary based on the inducer motor's RPM and static pressure requirements.
• Does this include the blower wheel or motor? This part number is for the inducer housing only; the motor and centrifugal wheel are typically sold separately unless specified in a full assembly kit.
• Why is my current housing leaking water? Condensation can collect if the furnace is not pitched correctly or if the secondary heat exchanger is restricted; ensure the housing gaskets are sealed to prevent flue gas leakage.
