The 0154F00004 is a genuine OEM sealing gasket cut and rated for the Goodman/Amana AMS80804BXAB gas furnace. It maintains an airtight seal between the combustion/collector assembly and the furnace cabinet, preventing flue-gas leakage and ensuring the induced-draft system pulls the correct pressure for clean, efficient burner operation.
A gasket's dimensions and temperature rating must match the mating surface exactly. This OEM gasket is die-cut to the factory footprint and rated for sustained furnace heat. Generic sheet-gasket substitutes risk incorrect thickness, premature breakdown, and CO/flue leaks — never worth the small savings on a combustion seal.
Requires partial disassembly of the affected panel or collector box, removal of the old gasket residue, and careful realignment. Budget 45–60 minutes. Recommended for experienced DIYers or a licensed HVAC technician. Always shut off power and gas, and pressure/leak-test the seal after reassembly.
Compatible with model AMS80804BXAB. Genuine OEM replacement, ready to ship.
