The Goodman M0570808 Button Plug is a genuine OEM snap-in plug for the AMVC961205DNBA gas furnace and compatible Goodman/Amana models. It seals unused knockouts, mounting holes, and access openings in the furnace cabinet or blower deck, keeping the enclosure sealed against air leakage, dust, and pests. On a sealed-combustion condensing furnace, maintaining a tight cabinet is essential for correct airflow and pressure-switch operation.
OEM vs. Generic: Off-the-shelf plugs often don't match the knockout diameter and can fall out or leave gaps that compromise the cabinet seal. This OEM plug is molded to the factory opening for a positive, lasting snap fit.
Installation difficulty: Very easy (DIY-friendly). No tools required — align the plug with the opening and press until it snaps flush and locks in place. Confirm it's fully seated for a complete seal.
Genuine Goodman OEM quality. Handy to keep on hand as a spare. Questions on fitment? Contact info@nationalhvacparts.com.
