Each in-shot burner directs a precise, focused flame into its heat-exchanger tube for efficient, clean combustion. Over time burners can corrode, clog with rust flakes, or develop flame-rollout and delayed-ignition issues — replacing them restores smooth lighting, even flame carryover, and full heating output.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMS81405DNA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Delivers a focused flame into the heat-exchanger tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-resistant aluminized\/coated steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e burners are venturi-matched to your furnace's manifold pressure and orifice sizing, ensuring proper air-fuel mixing and clean blue flame.
