The Goodman M0570808 Button Plug is a genuine OEM snap-in closure used to seal unused knockout holes on the burner box, control panel, or cabinet of Goodman and Amana gas furnaces, including the AMVC960803BNBA modulating variable-speed 96% AFUE furnace. Though small, this plug maintains proper cabinet sealing and airflow integrity, which is essential for safe combustion and correct blower performance.
The genuine Goodman part guarantees an exact snap fit in the factory knockout diameter. Universal plugs often sit loose or fail to seat fully, allowing air leakage that can affect furnace efficiency and safety-switch operation. For a component this inexpensive, OEM is always the smart choice.
Easy (1/5). No tools required — simply press the plug into the open knockout until it snaps flush. Always disconnect power before opening the furnace cabinet.
Fitment note: Verify your furnace model and the location of the plug before ordering. Compatible with a wide range of Goodman and Amana furnace platforms.
