The Goodman M0570808 Button Plug is a genuine OEM component for the AMSS921005CNAA gas furnace and compatible Goodman/Amana models. This snap-in plug seals unused knockouts, wiring-access holes, and cabinet openings to block air leaks, dust, and rodents while keeping the furnace jacket clean and correctly pressurized.
This factory OEM plug is dimensioned to your furnace's standard knockout size for a tight, flush snap-in fit. Generic plugs are frequently the wrong diameter and either fall out or won't seat, leaving gaps that undermine cabinet sealing and airflow. The genuine part ensures a clean, secure result.
Very Easy (1 of 5). No tools required — align the plug with the open knockout and press until it snaps flush. A quick, one-minute installation.
