This small but important fitting seats in the burner compartment door and holds the sight-glass window that lets a technician observe the burner flame during operation. It also seals the opening, maintaining proper combustion-chamber pressure and keeping the burner box closed to code. A cracked, missing, or brittle bushing can allow air leakage, flame-signal problems, or a rattling access panel.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: View port \/ sight-glass bushing (grommet)\u003c\/li\u003e\n\u003cli\u003eFunction: Retains burner viewport window and seals opening\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80903BNAA gas furnace\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded polymer\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eInstallation: Snap-fit into door opening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e bushing is molded to the exact diameter and profile of your furnace's viewport cutout, ensuring a snug, sealed fit.
