The M0570808 is a genuine Goodman/Amana OEM button plug engineered for the AMEC960803BNAC 96% AFUE gas furnace. This snap-in plug seals unused knockout holes and access openings in the furnace cabinet, blocking air leakage, dust, and pests while giving the panel a finished, factory appearance. It's a common part to replace after wiring or venting reconfigurations leave an open hole.
Universal plugs often fit loosely and pop out, defeating the air seal and letting conditioned air escape. This genuine OEM button plug is molded to the exact knockout diameter, snapping in tight and staying put. OEM ensures a proper seal and preserves your equipment warranty.
Easy (1/5). Push the plug into the open knockout until it snaps flush — no tools required, under a minute to install. Shut off power and gas before servicing the cabinet.
