The Goodman B1392139 View Port Bushing is a genuine OEM part for the ADSH801005CXAB gas furnace and related Goodman/Amana models. This bushing seals and frames the burner sight (view) port, letting a technician safely observe the flame while keeping the combustion chamber sealed against air leaks.
The OEM bushing is molded to match the exact port diameter on the ADSH801005CXAB, maintaining the combustion seal and heat resistance rating. Generic substitutes may not sit flush or withstand chamber temperatures, allowing air infiltration that affects flame stability. Choose OEM for a proper seal.
Easy — A simple press-fit replacement into the burner viewing port. Power down the furnace, remove the old bushing, and seat the new one. Typical service time: under 10 minutes. No special tools required.
