The Goodman 0154F00004 Gasket is a genuine OEM sealing component engineered as a direct-fit replacement for the WFM18090S4BXCC furnace. This heat-resistant gasket maintains an airtight seal between mating surfaces of the blower housing, burner box, or vestibule panel, preventing air leakage, flue-gas escape, and efficiency loss during operation.
This genuine OEM gasket is die-cut to the exact dimensions and material spec of the original, ensuring a proper compression seal on the first fit. Universal or trimmed generic gasket material can leave gaps, degrade faster under heat, and compromise combustion sealing. For safe, efficient operation, OEM is the reliable choice.
Easy to Moderate (2/5). Installation involves removing the panel or component, scraping away old gasket residue, cleaning the surface, and seating the new gasket before reassembly. Power should be off and, on gas units, verify no combustion leaks after service. Professional installation is advised for combustion-side seals.
