Factory Authorized Parts™ 48GS400649 Inducer Blower Assembly | 115V / 60Hz | 0.8 Amps | OEM Draft Inducer Motor Kit

The Factory Authorized Parts™ 48GS400649 serves as the critical "lungs" of your furnace's combustion cycle, acting as the primary draft inducer for the heat exchanger. This OEM-focused assembly is the specific module responsible for pulling air through the burners and exhausting harmful flue gases safely out of the vent pipe. Designed specifically for Carrier, Bryant, and Payne 48/58 series rooftop units and furnaces, this assembly ensures the system's "brain" (the pressure switch) can maintain the precise negative pressure required for the ignition sequence to begin. Replacing a seized or noisy motor with this authorized assembly restores factory-spec airflow and prevents safety lockouts caused by inadequate draft.

Key Features

• Complete OEM Assembly: Specifically engineered to replace part number 48GS400649, featuring a pre-mounted blower wheel and motor for a high-precision, "drop-in" installation.
• Corrosion-Resistant Housing: Built with high-temperature galvanized steel to withstand the acidic condensate and extreme heat produced during the gas combustion process.
• Dynamic Vibration Resolution: Every assembly is factory-balanced to eliminate the loud screeching, grinding, or vibrating noises that indicate a failing bearing or warped impeller.
• Sealed Ball Bearing Design: Features a permanently lubricated motor designed for continuous operation, reducing mechanical friction and extending the life of the internal components.
• Safety & Draft Monitoring: Calibrated to generate the exact static pressure needed to close the furnace pressure switch, ensuring the "brain" of the unit allows the gas valve to open safely.

🛠️ HVAC Depot Pro Tip

Take a Picture First: Before removing the old inducer, photograph the orientation of the exhaust outlet and the exact location of the pressure switch tubing. If the new 48GS400649 is installed without a tight seal, you will experience "nuisance trips" on the pressure switch. Conduct a diagnostic check by verifying the integrity of the fiberglass gasket; always replace or apply high-temp RTV silicone to the mounting flange to ensure an airtight seal between the inducer and the collector box.
