It seals the inspection port in the burner compartment door so you can safely watch the flame during a service check while maintaining the correct combustion-chamber pressure boundary. Over time the original bushing can dry out, crack, or fall out, leaving an open port that disrupts the sealed-combustion envelope. This OEM bushing restores a clean, tight fit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eType: View \/ sight port bushing (grommet)\u003c\/li\u003e\n\u003cli\u003eFits: AMVC81005CXBD and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Seals and frames the burner observation window\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat-resistant molded bushing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1392139\u003c\/strong\u003e is molded to the exact port diameter so it snaps in and holds the sight glass without gaps.
