The Goodman B1392139 View Port Bushing is a genuine OEM fitting for the AMEC960402BNAB gas furnace. This bushing frames and seals the flame-inspection view port on the burner or blower compartment, providing a clean opening for observing the burner flame while protecting the surrounding sheet-metal edge and helping maintain proper compartment sealing.

Specifications

Part Number: B1392139
Part Type: View port / sight-glass bushing
Material: Heat-resistant molded polymer
Equipment: Gas Furnace
Fit: Direct OEM replacement for AMEC960402BNAB

OEM vs. Generic

The genuine OEM bushing is sized to the furnace's exact port cutout and rated for the elevated temperatures near the combustion area. Generic substitutes may not seat flush or may use lower-temperature plastics that discolor, warp, or fail near the heat exchanger. For a component so close to the burner, the OEM part is the safe, correct choice.

Installation Difficulty

Very Easy (1/5). The bushing snaps into the port opening by hand and requires no tools. Always shut off power and gas before opening the furnace. When in doubt about any combustion-area service, consult a licensed HVAC professional.
