This small but important fitting seals the burner-observation port on the blower\/burner access panel, letting a technician watch the flame during startup while keeping the combustion area properly closed. A cracked, brittle, or missing view-port bushing can allow air leakage around the inspection window and affect combustion sealing — an inexpensive part worth replacing whenever it shows wear.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e View-port \/ sight-glass bushing (grommet seal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Seals the burner-flame observation port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temperature molded bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Press-fit into the panel port opening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e B1392139\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMH80905CNAB and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman B1392139\u003c\/strong\u003e is molded to the exact port diameter of the AMH80905CNAB access panel, so it snaps in flush and holds its seal at furnace operating temperatures.
