This small but essential bushing seats in the burner-compartment access opening, forming the sight-glass port that lets a technician safely observe the burner flame and ignition sequence without opening the sealed combustion area. It also helps maintain proper compartment sealing and appearance.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent type:\u003c\/strong\u003e View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocation:\u003c\/strong\u003e Burner compartment access panel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-tolerant molded bushing\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 AMH80904BNAB and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (Daikin family)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM B1392139\u003c\/strong\u003e is molded to the exact diameter and depth of the furnace's access opening, so it snaps in securely and seals correctly.
