The Goodman M0570808 button plug is a genuine OEM snap-in plug for the AMEC961005CNAB gas furnace. Button plugs seal off unused knockouts, wiring holes, and access openings in the furnace cabinet and sheet metal, keeping the enclosure air-tight and free of dust, debris, and pests. On a sealed-combustion furnace, closing these openings helps maintain correct static pressure and efficiency.
This OEM Goodman button plug matches the exact knockout diameter used in the factory cabinet, so it snaps in flush and stays put. Generic plugs are often the wrong size and work loose over time. For a clean, secure seal, choose OEM.
Very Easy (1/5). Press the plug into the open hole until it snaps flush with the panel. No tools required; under 1 minute.
