The Goodman M0570808 button plug is a genuine OEM cabinet fitting engineered for the VCSS961005CNAA gas furnace. This snap-in plug seals unused knockouts and access holes in the furnace cabinet, preventing air leakage, pest intrusion, and heat loss around the burner and control compartments. Manufactured to Goodman's exact tolerances, it seats flush and stays put through years of thermal cycling.
Our OEM M0570808 is molded to the precise diameter of Goodman's cabinet openings, so it snaps in and stays sealed. Generic universal plugs are often mis-sized, back out under vibration, and can whistle or leak conditioned air. For a clean, permanent seal, the factory part is the reliable choice.
No tools required. Simply press the plug into the open knockout until it seats flush. Always disconnect power before opening the furnace cabinet. Typical replacement time is under one minute.
