The Goodman B1822508S 5-Cell Burner Assembly is a genuine OEM replacement burner set for the Goodman GUPS120-5 gas furnace and compatible Goodman/Amana models. This complete assembly delivers a clean, properly shaped flame to each of the five heat exchanger cells, ensuring efficient, reliable combustion. Rusted, cracked, or misaligned burners cause poor ignition, delayed light-off (rollout risk), sooting, and reduced efficiency — replacing the full assembly restores factory combustion performance.
This genuine Goodman OEM assembly is engineered to the furnace's exact firing rate, port geometry, and flame-sensor placement. Aftermarket or mismatched burners can shift flame characteristics enough to trip the flame sensor, cause delayed ignition, or burn improperly. For a combustion component, OEM is strongly recommended for safety and performance.
Rated 4 of 5. Best performed by an HVAC professional. Plan for 1–2 hours: shut off gas and power, remove the burner compartment door, disconnect the gas manifold, igniter, flame sensor, and rollout switches, then remove and replace the burner assembly. Inspect the heat exchanger and orifices during service and verify flame color and sensor microamps on restart. Always confirm no gas leaks before returning to service.
