The Goodman M0570808 Button Plug is a genuine OEM cabinet fitting designed to seal unused knockouts and access openings on the AMEC960603ANAA gas furnace and other compatible Goodman/Amana models. Though small, this snap-in plug plays an important role in maintaining proper combustion airflow, blocking drafts, and keeping debris and pests out of the furnace cabinet.
This is the genuine Goodman OEM plug, molded to the exact diameter and retention-tab geometry of the factory knockout. Universal generic grommets are cheaper but frequently sit loose or pop out, allowing air leakage that can affect combustion and efficiency. Choosing the OEM part guarantees a flush, secure, permanent fit.
Rating: Very Easy (1/5). No tools required — align the plug with the open hole and press firmly until the retention tabs snap into place. Always shut off gas and power before servicing the furnace cabinet. Typical replacement time is under one minute.
Backed by our OEM guarantee and fast shipping, the M0570808 keeps your furnace cabinet properly sealed the way the factory intended.
