The Goodman B1392139 View Port Bushing is a genuine OEM grommet that seals the flame-observation (sight) port on the AMVC81005CXCA furnace and compatible Goodman/Amana models. This small but important fitting maintains the sealed integrity of the burner compartment while letting a technician visually confirm flame quality during service. A cracked, brittle, or missing bushing lets combustion air leak and can affect pressure-switch and flame-sensor readings.

OEM Part Number: B1392139
Type: View-port bushing / sight-glass grommet
Material: High-temperature-rated grommet
Function: Seals the flame-observation port in the burner box
Fits: Goodman & Amana AMVC81005CXCA furnaces
Brand: Goodman (OEM)

OEM vs. Generic

The OEM B1392139 is molded to the precise port diameter and rated for burner-compartment temperatures, so it seats fully and holds its seal over years of heat cycling. Generic grommets of the wrong size or a lower temperature rating can shrink, harden, and fall out. It's an inexpensive genuine part — no reason to substitute.

Installation Difficulty

Very Easy (1/5). Cut power, press out the old bushing, and press the new one into the port until it seats. Under 10 minutes with no tools required. A quick, worthwhile fix to keep the burner compartment properly sealed.
