This small bushing\/grommet seals and finishes the burner-compartment view (sight) port — the window a technician uses to observe the flame during startup. It keeps the combustion compartment properly sealed while allowing safe visual inspection, and prevents the sight-glass or port cover from rattling or leaking air.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1392139\u003c\/li\u003e\n\u003cli\u003eApplication: Burner view \/ sight port bushing\u003c\/li\u003e\n\u003cli\u003eCompatibility: Amana\/Goodman AMH80403AXBD and related 80% furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Seals and secures the flame-inspection port\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana family)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThough inexpensive, this bushing must match the port diameter and material to maintain a proper seal on the combustion compartment. The OEM B1392139 snaps into the factory opening precisely. A loose or ill-fitting generic grommet can allow air leakage that upsets the pressure switch or lets conditioned\/combustion air escape. For a few cents more, the exact-fit OEM part is the sensible choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eVery Easy (1\/5).\u003c\/strong\u003e Power off the furnace, pop out the old bushing, and press the new one into the port opening — a 5-minute job with no tools required. Confirm it seats fully and flush for a clean seal. As always, shut off power before opening the furnace, and consult a licensed HVAC technician if you're unsure.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057601528179,"sku":"GOODMAN-4994","price":0.85,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-view-port-bushing-for-amh80403axbd-furnace-b1392139","provider":"National HVAC Parts","version":"1.0","type":"link"}
