The Goodman B1392139 is a genuine OEM view port bushing for the AMH80704BXCB gas furnace. This small grommet seats in the burner-compartment sight/view port, providing a clean, sealed opening that lets a technician observe the burner flame while keeping the compartment properly closed. Though inexpensive, a correctly-fitted bushing helps maintain the intended airflow and appearance of the burner box.

Specifications

Type: View port bushing / grommet
Function: Seats and seals the burner viewing port
Material: Heat-resistant OEM material
Brand fit: Goodman & Amana furnaces
Primary model: AMH80704BXCB
OEM Part #: B1392139

OEM vs. Generic

The OEM B1392139 is molded to the exact diameter of the factory view port, so it snaps in and stays put. Off-size generic grommets tend to fall out or fit loosely, leaving a gap in the burner compartment. For a clean fit, use the genuine part.

Installation

Difficulty: Very easy. This is a tool-free, 5-minute replacement for most homeowners. Turn off power to the furnace, remove the old or missing bushing from the view port opening, and press the new bushing firmly into place until it seats around the rim. No wiring or gas work is involved.
