The Goodman M0570808 Button Plug is a genuine OEM snap-in cap that seals unused knockout holes on the cabinet or burner panel of the AMEC960603BNBB furnace and compatible Goodman/Amana units. When an accessory, wiring pass-through, or gauge port is not in use, this plug closes the opening to prevent air infiltration, dust intrusion, and combustion-air imbalance. Missing button plugs are a common cause of whistling, reduced efficiency, and nuisance draft-pressure faults.
OEM vs. Generic: The OEM M0570808 is sized precisely to Goodman's panel knockout diameter so its barbs lock without cracking the plug or leaving gaps. Generic plugs in an approximate size tend to pop out under blower pressure or fail to seal, undermining the sealed-combustion design. The genuine OEM plug guarantees a tight, permanent snap fit.
Install difficulty: Easy (1/5). With the furnace powered off, press the button plug firmly into the open knockout until the retaining barbs seat and it sits flush with the panel. No tools required; installation takes under a minute.
