Just went out and looked. Can't get to the buzzer from under it. Plate goes all the way up can see it from the front, but can't get a hand in there. Would like to put some tape on it like you said to quiet it. You can see the wires for it in one of the pics. Thing is laughing at me just out of reach.
Wires look alot closer in this pic than they are. About 6 or so inches from that hole.
