Goodman B1392139 View Port Bushing

The B1392139 is a genuine Goodman view port bushing for the AMES921004CNAA furnace. It seals and finishes the sight-glass/inspection port on the burner or heat-exchanger cabinet, maintaining the correct opening while protecting surrounding sheet metal edges. A missing or degraded bushing can allow air leakage around the port and compromise safe combustion observation.

Specifications

Part number: B1392139
Type: View port bushing / grommet fitting
Function: Seals the furnace inspection/sight port
Fits: Amana/Goodman AMES921004CNAA furnace
Sold individually

OEM vs. Generic

OEM bushings are molded to the exact port diameter for a leak-tight press fit. Universal grommets in the wrong size can fall out or leave gaps that affect draft. For a part governing combustion-area sealing, the OEM fit is worth it.

Installation Difficulty

Easy (1/5). Press-fit by hand into the port opening; no tools required. A few-minute job during routine service.
