The Goodman 10324248 Blower Housing is a genuine OEM replacement scroll and housing assembly engineered specifically for the WPH4436AHAA series and compatible Goodman/Amana package units. The blower housing channels and directs airflow off the blower wheel into the supply duct, and a cracked, corroded, or deformed housing causes air leaks, restricted CFM, and excessive noise. Installing the correct OEM housing restores rated airflow and keeps the blower wheel properly centered.
OEM vs. Generic: The genuine OEM 10324248 housing is stamped to factory tolerances so the blower wheel and motor mount line up on the first try, preserving the balance and clearance the unit was designed around. Generic or universal housings often require re-drilling mounting holes and can leave the wheel off-center, which shortens bearing life and creates vibration. For a package unit exposed to weather, the OEM galvanized finish also holds up better against rust.
Install Difficulty: Moderate — typically 45 to 90 minutes. Requires pulling the blower assembly, transferring the wheel and motor, and re-squaring the housing in the cabinet. Basic hand tools and HVAC service experience recommended. Always disconnect power before servicing.
Every part is inspected before shipment. Confirm your model and serial number match before ordering to guarantee an exact fit.
