This small grommet-style bushing seals the burner-compartment sight port, letting a technician visually confirm the flame while maintaining the cabinet seal on high-efficiency furnaces. Over time the bushing can become brittle, cracked, or lost, which allows air leakage around the inspection port and can affect combustion-air balance. Replacing it restores a clean, sealed viewing window.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eType: View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFM18090S5CXCC and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded bushing\u003c\/li\u003e\n\u003cli\u003eFunction: Seals and frames the burner inspection port\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this bushing seats into a precise opening in the burner box, the OEM part guarantees a correct, airtight press fit. Generic grommets rarely match the diameter and depth, leading to air leaks or a bushing that falls out. For such an inexpensive part, the genuine OEM piece is always the right call.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Very Easy (DIY-friendly)\u003c\/h3\u003e\u003cp\u003eNo tools required in most cases — simply press the old bushing out and snap the new one into the port opening. A 2-minute replacement.
