The Goodman M0570808 Button Plug is a genuine OEM snap-in plug for the AMSS961205DNAA furnace. It seals unused knockouts and access holes in the furnace cabinet, blocking dust, air leakage, and pests while maintaining the intended airflow and combustion sealing of the unit.
Genuine M0570808 plugs match the exact knockout diameter for a flush, positive snap fit. Generic plugs may be undersized and fall out, or oversized and refuse to seat — compromising the cabinet seal. The OEM part restores the factory-tight enclosure.
Difficulty: Very Easy (1/5). Push the plug into the open knockout until it snaps flush — no tools needed. De-energize the furnace before servicing.
