This bushing frames and seals the burner observation (sight) port, allowing a technician to visually inspect the flame while keeping the combustion chamber sealed against air leaks. A cracked or missing bushing can disturb the combustion-air balance and pressure-switch reference, and lets flame-viewing light and heat escape improperly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1392139\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e View \/ sight port bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMSS960402BNAA and matching Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-temperature molded grommet\/bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The factory bushing is molded from a heat-rated material sized to the exact view-port cutout on Goodman burner assemblies.
