The Goodman M0570808 button plug is a genuine OEM cabinet fitting engineered for the ACES960403BNAA gas furnace and other compatible Goodman/Amana 96% AFUE models. This small but essential component snaps into unused knockout and access holes in the furnace cabinet, blanking off openings that are not in use for a given installation configuration. Properly plugged openings maintain the sealed cabinet integrity the furnace was designed around — preventing air leakage, blocking debris and pests, and helping the unit hold rated combustion-air and blower performance.
This is a factory OEM Goodman plug machined to the exact knockout diameter, so it seats flush and locks without gaps. Generic plugs are often undersized or oversized, leading to rattles, fall-out, or air leaks. For a part this inexpensive, the OEM fit guarantees a clean, permanent seal.
Very Easy (1/5). No tools required — align the plug with the open hole and press until it snaps into place. A typical install takes under a minute.
