It seals the inspection port on the burner compartment, letting a technician safely observe the flame during operation while maintaining the furnace's sealed-combustion integrity. A cracked, missing, or hardened bushing can allow flue-gas leakage and heat loss around the viewing window, so a factory-spec replacement is the correct fix.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B1392139\u003c\/li\u003e\n\u003cli\u003eType: View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003eFits: AMEC961004CNAC gas furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature molded grommet\u003c\/li\u003e\n\u003cli\u003eApplication: Burner compartment inspection port\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1392139 is molded to the exact port diameter and heat rating specified by Goodman, ensuring a tight seal and long service life at combustion-chamber temperatures. Aftermarket grommets often use lower-temperature rubber that hardens and shrinks, leading to repeat failures. For a sealed-combustion appliance, we recommend the genuine OEM part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e No tools required in most cases — power down the furnace, remove the old bushing, and press the replacement into the port.
