This genuine OEM Goodman natural gas burner orifice (spud) is a direct-fit replacement for the WFD195090S5DAA gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, setting the flame size and combustion quality. A worn, corroded, or incorrectly drilled orifice causes poor flame, sooting, delayed ignition, or reduced efficiency. Using the correctly sized OEM orifice keeps combustion clean, safe, and to specification.
The OEM orifice is drilled to Goodman's exact bore size for this furnace's BTU rating — critical for safe combustion and correct gas pressure. A Generic equivalent may match the thread but can vary in bore, risking over/under-firing. For a fuel-metering component, OEM is strongly recommended.
Moderate (2/5). Shut off gas and power, remove the burner assembly or manifold as needed, unthread the old orifice, and install the new one to spec. Verify manifold pressure after install. Best performed by an HVAC technician. Typical install time: 20–30 minutes.
