The Goodman M0570808 is a genuine OEM button plug used to seal unused knockouts and access holes on the AMEC960303ANAB gas furnace cabinet. It snaps into the sheet-metal opening to block air bypass, insulation shedding, and small-debris intrusion, helping the furnace hold its rated efficiency. As a shared Goodman/Amana component, it is a factory-correct fit for the AMEC-series cabinet.
The OEM M0570808 is sized to the exact knockout diameter so it locks in flush and stays put under blower pressure. Universal plugs frequently fit loosely, back out over time, or leave a gap that whistles. Choose the genuine Goodman plug for a clean, secure, leak-tight seal.
Easy — DIY friendly (1/5). No tools required; align the plug with the open knockout and press until it snaps home. Turn off power and gas to the furnace before servicing. If unsure which opening the plug belongs to, refer to the furnace parts diagram.
