The Goodman M0570808 button plug is a genuine OEM cabinet fitting designed for the Goodman ACSS960402BNAA 96% AFUE gas furnace and many compatible Goodman/Amana models. This snap-in plug seals unused knockout and access openings in the furnace cabinet, keeping out dust, debris, and conditioned-air leakage so your furnace runs clean and efficiently.
This is the genuine Goodman OEM part, molded to the exact knockout diameter for a flush, rattle-free seal. Universal generic plugs often sit loose or fall out over time; the OEM M0570808 locks in on the first push and is the part your furnace was built with.
Easy (1/5). No tools required — simply press the plug into the open knockout until it snaps flush. Always disconnect power before opening the furnace cabinet.
