The Goodman B1392139 is a genuine OEM view port bushing (sight-glass grommet) for the AMS81155CXA gas furnace and compatible Goodman/Amana models. This small but important component seals the burner-compartment inspection port, allowing a technician to visually confirm flame quality and burner ignition while keeping the combustion chamber sealed against air leaks.

A cracked, melted, or missing view port bushing can allow air infiltration that affects combustion and draft, or simply obscures the inspection window. Replacing it with the correct OEM part restores a clean, sealed sight port.

  • Type: View port / sight-glass bushing
  • Material: Heat-resistant grommet
  • Function: Seals the burner inspection window
  • Fits: Goodman AMS81155CXA and compatible furnaces
  • OEM Part #: B1392139

OEM vs. Generic: The genuine Goodman bushing is molded to the exact bore diameter and thickness of the furnace panel opening for a snug, sealed press fit. Generic grommets are available at a lower cost, but diameter and heat rating can vary, risking a loose fit. For a proper seal, OEM is recommended.

Install Difficulty: Very Easy (1/5). Pop the old bushing out of the panel opening and press the new one in by hand—no tools required. Ensure power and gas are off before opening the furnace cabinet.

What symptoms mean I need a new fitting?
Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this fitting compatible with Bryant or Payne too?

To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman fitting?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
