The Goodman M0570808 Button Plug is a genuine OEM snap-in plug used to seal unused knockouts and access holes on the AMSS920402BNAA gas furnace cabinet and compatible Goodman/Amana models. Keeping these openings sealed preserves proper cabinet pressure, blocks conditioned-air leakage, and keeps dust, insects, and debris out of the blower and control areas.

Specifications

Part Type: Button / Hole Plug
OEM Part Number: M0570808
Fits: Goodman & Amana AMSS920402BNAA and related furnaces

OEM vs. Generic

Genuine Goodman plugs are sized precisely to factory knockout diameters so they seat flush and lock securely. Generic plugs often fit loosely, pop out during blower cycling, or fail to seal — undermining the cabinet's pressure balance. The OEM M0570808 guarantees a tight, lasting fit.

Installation Difficulty

Easy (1/5). Press firmly into the open knockout until the locking flange snaps home — no tools required. Cut power and gas before opening the cabinet. When in doubt, use a licensed HVAC professional.

Shipped fast with a 30-day return policy. Order the genuine Goodman M0570808 button plug to keep your furnace cabinet sealed and efficient.
