Goodman B1392139 View Port Bushing

This genuine OEM Goodman B1392139 view port bushing is the small sealing grommet that frames the combustion sight-glass opening on the AMVC800805CNAB 80% AFUE two-stage furnace. It lets a technician observe the burner flame while keeping the burner compartment sealed against air leaks, and it protects the surrounding sheet metal from chafing. A hardened, cracked, or missing bushing can allow air infiltration that upsets the pressure-switch signal or the flame view, so this inexpensive part keeps the combustion area buttoned up correctly.

Specifications

OEM Part Number: B1392139
Category: Fittings / Grommets
Compatible Model: AMVC800805CNAB (Goodman/Amana 80% two-stage furnace)
Function: Sight-glass / view-port sealing bushing
Fit Type: Direct OEM snap-in replacement

OEM vs. Generic

The OEM B1392139 is molded to the exact bore and panel thickness of the AMVC8 cabinet, so it snaps in and seals without fuss. A generic grommet that is a hair too large or small either falls out or will not seat, defeating the seal. At this price, matching the factory part is the obvious call.

Installation Difficulty

Easy — a simple push-in replacement requiring no tools in most cases. Shut off power, pop out the old bushing, and press the new one fully into the panel opening until it seats. Confirm the burner door reseals properly afterward.
