The Goodman B4022700 is a genuine OEM 3-inch in-shot burner for the Goodman / Amana ACVC80603BXBC gas furnace. In-shot burners deliver the gas/air mixture into the heat exchanger tubes, producing the clean, stable blue flame your furnace needs for efficient, safe heating. Over time burners can rust, clog, or distort, causing rough ignition, delayed light-off, sooting, or uneven heat. Replacing worn burners restores reliable combustion.
The factory B4022700 is shaped and ported to match your furnace's manifold spacing and orifice alignment exactly, ensuring proper flame carryover between burners. Generic burners can misalign with the orifice, throwing off the air-fuel mix and tripping flame-sensing faults. OEM guarantees correct combustion geometry.
Moderate (2/5). Shut off gas and power, remove the burner assembly, swap the burner(s), and verify proper flame on relight. Budget 30–45 minutes. Replace burners as a matched set for even firing when possible.
