The Goodman B1392139 View Port Bushing is a genuine OEM sight-glass grommet for the AMS80453ANA furnace and compatible Goodman/Amana gas models. It seals the burner-observation port on the vestibule panel, letting a technician safely view flame ignition and rollout while maintaining the airtight integrity of the combustion compartment. Over time the original bushing can harden, crack, or fall out—allowing air leaks that affect combustion and draft.

Specifications

Type: View port / sight-glass bushing (grommet)
Function: Seals burner observation port on vestibule panel
Material: High-temperature molded grommet
Fits: Goodman/Amana AMS80453ANA and compatible furnaces
OEM Part #: B1392139

OEM vs. Generic

The OEM Goodman B1392139 is molded to the exact panel-hole diameter and high-temp material spec for a proper airtight seal. Our generic equivalent fits the same port at a lower price for routine service. Both are new, heat-rated parts—don't substitute a standard rubber grommet, which can't handle vestibule temperatures.

Installation Difficulty

Very easy (1/5). With the furnace powered off, press the old bushing out of the panel and snap the new one into place by hand. A 2-minute, tool-free replacement.
