This small but essential component seals the burner inspection port on the combustion cover, letting a technician safely observe the burner flame while keeping the combustion chamber properly sealed. A missing or degraded bushing can cause air leaks that disturb the flame pattern and trigger pressure-switch or flame-sensing faults.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Seals the burner observation port on the combustion cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temperature molded grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS80704BXA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1392139\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine B1392139 is molded to the exact port diameter and heat rating of the original, ensuring a tight, lasting seal. Generic grommets often fit loosely or harden and shrink near the combustion area, breaking the seal and inviting the very air leaks this part is meant to prevent.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy (DIY-friendly). The bushing simply presses into the port opening — no tools required beyond removing the burner cover. Shut off power and gas first, seat the new bushing fully, and confirm it sits flush for a complete seal. If you notice flame disturbances or combustion issues afterward, consult a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057691476339,"sku":"GOODMAN-6934","price":6.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-view-port-bushing-for-ams80704bxa-b1392139","provider":"National HVAC Parts","version":"1.0","type":"link"}
