Quoted from awassig:Anybody's ACNC make a coil buzzing sound when holding in a flipper button? I've read alot of stern machines have this issue. Is there a fix?
My left flipper was insanely loud and the right wasn't all that much better. I changed out the coil stops even though they didn't look all that bad. The left flipper is perfect now. I can still hear a faint buzzing on the right flipper but not like it was.
