Goodman B1392139 View Port Bushing

The B1392139 is a genuine Goodman/Amana view port bushing used on the AMH80704BXCA 80% AFUE gas furnace and other compatible models. This bushing surrounds the burner sight/view port, giving technicians a clean, sealed opening to observe the flame during operation while helping maintain the integrity of the burner compartment. A cracked or missing bushing can allow the sight glass to loosen or admit air where it shouldn't.

Specifications

Part number: B1392139
Type: OEM view port / sight-glass bushing (grommet)
Function: Seats and seals the burner observation port
Material: Heat-resistant molded bushing
Fits: Goodman & Amana gas furnaces including AMH80704BXCA

OEM vs. Generic

This OEM bushing is molded to the furnace's exact port diameter for a snug, rattle-free fit. Off-brand grommets are frequently the wrong size or made from material that hardens near the burner heat, leading to a loose sight glass or air leaks. For a small part in a hot area, the exact-fit OEM piece is worth it.

Installation Difficulty: Easy

Replacement is straightforward: shut off power, remove the burner access panel, pop out the old bushing, and press the new one into the view port opening until it seats fully. It typically takes only a few minutes with no special tools. Reinstall the panel and confirm the sight port is secure.
