The Goodman M0570808 Button Plug is a genuine OEM snap-in plug used to seal unused knockout or access holes in the sheet-metal cabinet of your AMES961205DNAA 96% AFUE two-stage gas furnace. It keeps conditioned air, dust, and combustion air where they belong by closing off factory knockouts left open after wiring, venting, or accessory installation. A missing button plug can cause air leaks, whistling noise, and reduced blower efficiency.
The genuine OEM M0570808 is sized to the exact knockout diameter used on Goodman/Amana cabinets, so it snaps in flush and locks securely. Generic plugs are often the wrong diameter and either fall through or won't seat, leaving a persistent air gap. Buy the OEM plug for a guaranteed tight fit.
Easy (1/5). Push the plug into the open knockout until it snaps flush — no tools needed. Under 2 minutes. Turn off power to the furnace before opening any panels.
