The Goodman 0154F00004 Gasket is a genuine OEM sealing component for the WGFM28070V4BXAB gas furnace and related Goodman/Amana models. This gasket maintains an airtight, heat-resistant seal between furnace assemblies — such as the burner box, collector box, or inducer housing — preventing flue-gas leakage and pressure loss that can trip pressure switches or degrade combustion efficiency.
OEM gaskets are die-cut to the precise dimensions and bolt-hole pattern of your furnace, ensuring a leak-free seal on the first fit. Trimming a generic sheet gasket risks gaps, blow-out under pressure, and failed combustion-safety checks. This factory part removes the guesswork.
Because a compromised seal can cause draft and pressure-switch faults, the OEM gasket is the reliable long-term choice.
Moderate (3/5). Requires partial disassembly of the affected furnace section, careful removal of old gasket residue, and proper reseating of the mating surfaces. Disconnect power and gas before service. Budget 30–60 minutes; verify for leaks after reassembly.
