The Goodman M0570808 Button Plug is a genuine OEM snap-in hole cap used to seal unused knockouts and access holes in the sheet-metal cabinet of the AMES920603BNAA gas furnace and compatible Goodman/Amana units. Sealing these openings keeps conditioned air, combustion air, and debris where they belong and preserves the furnace's rated airflow and efficiency.
The OEM Goodman plug matches the factory knockout diameter and retention flange so it snaps in flush and stays put. Off-brand plugs are often loose or oversized, leading to air leaks and rattles. For a clean, permanent seal, use the OEM cap.
Difficulty: Easy (1/5). No tools required — align the plug with the open knockout and press until the flange snaps home. Under 5 minutes. Ideal for closing off holes left after removing an accessory or wiring pass-through.
