It seals the burner observation (sight-glass) opening on the combustion enclosure, letting technicians inspect the flame while maintaining a proper seal against air infiltration. A cracked or missing bushing can disturb combustion-chamber pressure and allow air leakage that affects flame quality and pressure-switch operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eType: View-port \/ sight-glass bushing (grommet)\u003c\/li\u003e\n\u003cli\u003eFunction: Seals the burner observation opening\u003c\/li\u003e\n\u003cli\u003eCompatibility: AMVC960804CNBA and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana-compatible)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1392139 is sized to the exact port bore on this furnace's burner enclosure, giving an air-tight fit that generic grommets rarely match. Because it seats on a combustion-side opening, an imprecise seal can subtly affect flame and pressure readings — making the correct OEM bushing the reliable choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eVery Easy (1\/5).\u003c\/strong\u003e Disconnect power, remove the burner\/combustion cover if needed, press out the old bushing, and push the new one into the port until fully seated.
