Goodman B1392139 View Port Bushing

The B1392139 is a genuine OEM view port (sight glass) bushing engineered for the Goodman/Amana AMH80805CXBA gas furnace. It press-fits into the burner compartment panel and holds the flame-observation window in place, letting a technician safely watch burner ignition and flame quality without opening the cabinet. A cracked or missing bushing can allow combustion air leakage and inaccurate flame readings, so a proper OEM replacement matters.

Specifications

Part type: View port / sight-glass bushing
OEM part number: B1392139
Compatible model: AMH80805CXBA (Goodman & Amana equivalent)
Material: High-temperature molded polymer
Fit: Direct OEM press-fit, no modification required

OEM vs. Generic

Our OEM B1392139 is molded to the exact diameter and heat rating Goodman specifies, so it seats flush and holds the sight glass without gaps. Generic bushings often run undersized or use lower-temp plastic that warps near the burner box, leading to a loose window and false flame readings. For a $10 part next to a combustion chamber, OEM is the safe choice.

Installation Difficulty

Easy (1/5). Power down the furnace, pop the old bushing out, and press the new one in — typically a two-minute job with no tools. Always confirm the furnace is off and cool before working near the burner compartment.
