The contactor in the unit,(the thing that's buzzing), has an electromagnetic
coil that pulls the contacts together. If it doesn't seat properly, it will
buzz. Sometimes it's a matter of insect debris, or oxidation causing this.
Kill the power to the unit, open it up, look at it and see if you can clean
it up and stop the buzz. A little WD-40 may help, but don't get it on the
electrical contacts
