Keep your Goodman ADSS800804BXAD furnace firing cleanly and efficiently with this genuine OEM natural gas burner orifice (spud). The orifice meters the precise volume of natural gas delivered into each burner, setting the furnace's BTU input and combustion quality. A worn, corroded, or incorrectly sized orifice causes lazy yellow flames, sooting, delayed ignition, and reduced heating capacity.
Orifice drill size directly controls your furnace's firing rate and safety. Our OEM Goodman orifice is machined to the exact bore diameter specified for this furnace's manifold pressure, guaranteeing the rated BTU input and a clean blue flame. Generic orifices with off-spec bores can over- or under-fire the unit, risking incomplete combustion and carbon monoxide. Match OEM every time.
Easy–Moderate (2/5). Shut off gas and power, remove the burner assembly access, and unthread the old orifice from the manifold with a deep socket. Thread in the new orifice, reassemble, and verify flame appearance and manifold pressure. Roughly 20–30 minutes. If you are not comfortable working on the gas train, have a licensed HVAC technician perform the swap and confirm combustion.
