The Goodman M0570808 Button Plug is a genuine OEM fitting designed for the Amana/Goodman AMEC960403ANAA gas furnace. This snap-in plug seals unused knockout holes and cabinet openings, keeping conditioned airflow inside the furnace and blocking dust, debris, and pests. A missing or damaged plug can create air leaks that reduce heating efficiency and trip pressure-related lockouts.
Genuine OEM plugs are molded to the exact hole diameter of your furnace cabinet, guaranteeing a flush, airtight snap fit. Generic universal plugs are cheaper but often loosen or fall out over time, reintroducing the air leak you were trying to fix. For a fitting this inexpensive, OEM is always the smarter buy.
Beginner (1/5). No tools required — simply press the plug into the open hole until it seats. Always shut off power and gas before working on your furnace.
