The Goodman B4022700 3-inch In-Shot Burner is a genuine OEM replacement for the Amana/Goodman AMH80905CXAA 80% AFUE gas furnace. Each in-shot burner directs the gas/air mixture into a corresponding heat-exchanger tube, producing the clean, stable blue flame required for efficient combustion. Furnaces of this size typically use several burners in a rack — replace any that are cracked, rusted, or producing an uneven flame.
The genuine B4022700 is stamped and slotted to Goodman's exact port geometry, ensuring correct flame carryover and combustion. Aftermarket burners can differ subtly in port spacing and orifice alignment, causing rough ignition, delayed lightoff, or sooting. Because burner performance directly affects safety and heat-exchanger life, OEM is strongly recommended.
Rated 3 of 5. Replacing a burner requires removing the gas manifold and burner assembly, then reseating the burner over its orifice and aligning it with the flame sensor and igniter. Basic hand tools and care during reassembly are needed. Always shut off gas and power, and verify proper flame after service.
