This small but important component seals and frames the burner observation (sight) port on the furnace cabinet, allowing technicians to view flame color and ignition while keeping the combustion area properly enclosed. A cracked, missing, or brittle bushing can allow air leakage around the port and make flame inspection difficult.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1392139\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temperature molded polymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Seals and frames the burner observation port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS80704BNAA and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Because it is molded to the exact port diameter and cabinet thickness of the AMS80704BNAA, the OEM B1392139 snaps in cleanly and holds its seal under repeated heat cycling. Generic grommets rarely match the port geometry and can fall out or degrade quickly. At this price point, buying the correct OEM part is a simple, low-cost way to keep the furnace factory-correct.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Very easy (1\/5).
