The genuine Goodman B1392139 View Port Bushing is the direct-fit grommet that frames and seals the burner viewing port on the Goodman/Amana AMVC80805CXBC gas furnace. This small but important component lets a technician safely watch the burner flame during service while maintaining the sealed integrity of the combustion compartment. A cracked or missing bushing can allow air leakage that upsets combustion and flame-sense readings.
Because this bushing seals a combustion-area opening, the material must withstand sustained heat without hardening or shrinking. Generic grommets often degrade quickly and fall out. The inexpensive OEM Goodman part is molded to the exact port diameter and heat rating for a lasting, airtight fit.
Easy — a 5-minute snap-in job. With power off, press the old bushing out and seat the new one into the port opening. No tools typically required. An ideal add-on part when servicing the burners or flame sensor.
Inspect and replace whenever it shows cracking or hardening.
