The Goodman B1392139 is a genuine OEM view port bushing for the AMEC800803BNAA furnace. This small but important component frames and seals the burner-compartment sight port, letting a technician safely observe the flame and burner ignition while maintaining the compartment's air seal. A missing or damaged bushing can disrupt combustion airflow and allow flame-rollout inspection to be inaccurate.
Because this bushing controls a sealed opening in the combustion area, OEM fit matters — the correct diameter and heat rating keep the port sealed and safe. Generic grommets may not match the port size or tolerate the heat, compromising the seal. OEM is recommended.
Very Easy (1/5). A quick press-in/snap replacement, typically under 10 minutes. Shut off power and gas before opening the burner compartment.
Confirm your model and serial before ordering. Genuine Goodman OEM part.
