The Goodman 0154F00003 14 inch Vent Motor Gasket is the OEM seal that fits between the inducer/vent motor housing and the flue collector on the ACES800403ANAA furnace and compatible Goodman and Amana gas furnace platforms. A cracked, hardened, or missing vent gasket is one of the most common causes of flue gas leakage, inducer noise, and pressure-switch faults — replacing it restores a tight, code-compliant draft path.
This is the genuine factory gasket, die-cut to the exact bolt pattern and port geometry of the original. Generic universal gaskets often require trimming and can leave gaps that let combustion byproducts escape. For a safety-critical flue seal, the OEM part is the recommended choice and protects any remaining manufacturer warranty.
Easy — typically a 15–20 minute job. Power down the furnace at the disconnect, remove the inducer/vent motor fasteners, scrape away the old gasket, set the new 0154F00003 in place, and reassemble. No special tools beyond a nut driver are required. If you are unsure about combustion-side service, contact a licensed HVAC technician.
