The Goodman M0570808 is a genuine OEM button (hole) plug engineered for the Amana/Goodman AMVC960804CNAA variable-speed communicating gas furnace. This small but essential fitting seals an unused knockout or access hole in the furnace cabinet, preventing air leakage and maintaining the sealed-combustion airflow your furnace relies on for safe, efficient operation. A missing or damaged plug can allow conditioned air to escape and combustion air to be drawn from the wrong location.
Generic plugs are often sold by approximate diameter and may not seat fully in Goodman cabinet openings, leaving gaps. The OEM M0570808 is molded to the exact knockout dimension for a flush, airtight snap fit — no rattles, no leaks, and a factory-correct appearance.
Rating: Easy (1/5). No tools required. Simply press the plug into the open cabinet hole until it snaps flush. Always disconnect power before opening the furnace panel.
Fits the AMVC960804CNAA. If your unit differs, verify the model tag before ordering.
