Maintain a leak-free combustion seal on your Amana AMVC800604BNAB furnace with the genuine Goodman 0154F00004 gasket. This high-temperature seal is used at the burner, collector box, or heat-exchanger interface to prevent flue-gas and combustion-air leakage. Whenever these assemblies are opened for cleaning or heat-exchanger inspection, the original gasket should be replaced — reusing a compressed or torn gasket risks flue leakage and reduced combustion efficiency.
A generic sheet-gasket cut to approximate size rarely matches the exact bolt pattern and thickness, and off-spec material can break down or off-gas at combustion temperatures. This factory OEM gasket is die-cut to the precise footprint and thickness the assembly requires, ensuring a proper crush and a durable, code-compliant seal.
This is a 30-60 minute job that involves opening a sealed combustion assembly. Shut off gas and power, scrape all old gasket material from both mating surfaces, seat the new gasket without distorting it, and torque the fasteners evenly in a cross pattern. Because it involves the combustion path, homeowners uncomfortable with furnace disassembly should have a licensed HVAC technician perform the replacement.
