It seals the inspection port in the burner compartment door so a technician can observe the flame during operation while keeping combustion air and flue gases properly contained. A cracked, missing, or hardened bushing lets ambient air leak into the sealed combustion path, which can trip the pressure switch or cause nuisance lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: View port bushing \/ sight-glass grommet\u003c\/li\u003e\n\u003cli\u003eMaterial: High-temperature rated elastomer\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMVC8 series (AMVC81005CXBC and related 80% AFUE models)\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1392139\u003c\/li\u003e\n\u003cli\u003eEquipment: Two-stage variable-speed furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the \u003cstrong\u003efactory OEM Goodman\u003c\/strong\u003e component, molded to the exact port diameter and temperature rating specified for the AMVC8 cabinet.
