The Goodman B1822508S is a genuine OEM 5-cell burner assembly engineered specifically for the GUP100-5 gas furnace. As the component that mixes fuel and air for combustion, the burner assembly is critical to safe, efficient, and even heating. This factory-matched unit bolts directly into the burner box, aligning cell spacing to the heat exchanger for clean flame carryover across all five cells.
The OEM B1822508S guarantees exact cell geometry and mounting alignment, preserving factory flame patterns and safety certifications. Generic multi-cell burners can misalign flame carryover, causing delayed ignition, sooting, or nuisance flame-sensor lockouts. For a combustion component, OEM is the safe choice.
Moderate–Advanced. Requires shutting off gas and power, removing the gas valve/manifold, and swapping the burner assembly with correct orifice alignment. Combustion work should be performed by a qualified HVAC technician, and the furnace should be leak- and flame-tested after service.
