Carrier 326627-757 Housing Assembly

The Carrier 326627-757 Housing Assembly is a precision-engineered OEM inducer housing kit designed for direct field replacement of the 326627-707 component. As a veteran technician knows, maintaining the integrity of the combustion blower assembly is critical for safe flue gas venting and pressure switch calibration. This housing is constructed from high-grade, heat-resistant polymers to withstand the thermal stresses of continuous furnace cycles. It features integrated mounting holes and is supplied with the necessary fasteners to ensure a sealed fit against the collector box. Specifically designed for 58STA and 58STX series units, this direct-drive inducer housing ensures optimal static pressure and prevents the common "pressure switch stuck open" errors associated with cracked or warped aftermarket housings. Rigorous factory testing guarantees exact tolerances for the inducer wheel clearance, maximizing HVAC blower airflow efficiency and reducing vibration noise in high-efficiency gas furnaces.

• Direct OEM Substitute: Specifically engineered to replace the legacy 326627-707, ensuring total compatibility with the existing motor mount and venting.
• Enhanced Thermal Stability: Built with robust materials that resist warping under high localized temperatures near the heat exchanger.
• Rapid Field Installation: Includes pre-drilled alignment holes and mounting hardware, reducing downtime during emergency service calls.
• Optimized Flue Logistics: Precisely molded internal air paths maintain the required CFM for proper draft and combustion safety.

Is this a direct fit for the older 326627-707 housing?
Yes, the Carrier 326627-757 is the official manufacturer-designated replacement for the 707 series, utilizing the same footprint and bolt pattern.

Does this assembly include the inducer motor or wheel?
This part is the housing assembly only. It is designed to house your existing or new motor and wheel while providing the essential seal and airflow channel for the combustion process.

Will this resolve vacuum pressure switch issues?
If the diagnostic fault is caused by a cracked housing, air leakage at the gasket, or structural failure of the draft inducer casing, this OEM replacement will restore the necessary vacuum levels for the pressure switch to close.
