After only 3 weeks the beverage center got really loud. I hope it was because something in the motor or fan got frozen.  I turned the unit off and let it thaw for a day (as there was frost build-up along the inside back wall )and last night plugged it back in. It seems to be running fine although I have the thermostat set at 40 instead of 37 as I has before.  If this grinding noise starts up again, Frigidaire, you must do better and I will be calling...
