This bushing seals the sight-glass inspection opening on the burner\/combustion compartment, letting a technician safely observe the burner flame while keeping the combustion area sealed against air leaks. A brittle, cracked, or missing bushing can allow drafts that disrupt the flame pattern and trip the flame sensor — a small part that protects reliable ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1392139\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e View Port Bushing \/ Sight-Glass Grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas Furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Fit:\u003c\/strong\u003e Goodman AMVC80604BNBD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso Fits:\u003c\/strong\u003e Select Goodman \u0026amp; Amana furnace models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temperature molded grommet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM ensures the bushing matches the port diameter exactly for a snug, sealed press-fit.
