Holding the 2 button for about 5 seconds works for me. You should hear an initial chirp after pressing 2 and then another short series of 3 chirps after holding for 5 seconds. You can then release and try it out. I have a 2005 1800W Whirlpool model. It works like a toggle so you can undo this as needed/desired. It may not be universal but I have tried this on a few other microwaves and it has worked.

How do you turn the "beep" back on?
