B-room A?C humm

I have a 2013 Columbus 320 that has had the front A/C replaced due to the vibration problem. My problem now is the A/C works fine but when it cycles off the A/C has a fairly loud humming noise coming from it (this happens about 5 minutes after unit cycles off. I then have to switch breaker off and turn on and the humming goes away. Any thoughts??
