The Goodman 0154F00003 14-inch Vent Motor Gasket is the genuine OEM seal that mounts between the draft inducer (vent) motor assembly and the heat exchanger collector box on the ADSH800403AXAA gas furnace and compatible Goodman/Amana models. A flattened, hardened, or torn gasket is one of the most common causes of a flue-gas leak, a tripped pressure switch, or a noisy inducer — replacing it restores a positive, airtight seal so the furnace drafts correctly and safely.
This is a genuine OEM Goodman gasket cut to the exact bolt pattern and thickness of the original. Generic universal gasket material can be trimmed to fit but rarely seats evenly on the collector box flange, which risks a slow flue-gas leak. For a safety-critical combustion seal we recommend the OEM part.
Easy (1/5). Power off, remove the inducer mounting screws, peel the old gasket, clean the flange, set the new gasket, and reassemble. Typically a 10–15 minute job with a nut driver. Always verify proper draft after install.
