This small but essential grommet seals the sight-glass opening on the burner compartment, letting a technician safely observe flame ignition while keeping the combustion area properly enclosed. A missing or degraded bushing can allow air infiltration that disrupts the flame pattern and combustion pressure.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: B1392139\u003c\/li\u003e\n\u003cli\u003eComponent: View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80403AXBA furnace\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded polymer\u003c\/li\u003e\n\u003cli\u003eType: OEM exact-fit replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\n\u003cp\u003eThe genuine OEM B1392139 is molded to the precise diameter of the Goodman view-port cutout, so it snaps in flush and holds a clean seal.
