An AC relay can occasionally buzz somewhat if it pulls in for some reason just a little out of its normal position. My Clipper Creek has not done that (yet), but if it does I would not worry unless it becomes regular.

240v charger was buzzing like a transformer...
Went out to my garage and heard a buzzing sound coming from my Sun Country (Clipper Creek) 240v charger. It sounded very much like a transformer buzz you hear from a large transformer, not real loud but loud enough to hear it in the hallway beside the attached garage. I unplugged the charger from the car, waited a few seconds, plugged the charger back into the car and all is normal again.
Has anyone else experienced this and could this be a sign of imminent failure? The charger is about 3 years old and is used daily. I guess time will tell but I have never heard any sounds from the unit other than when the relay operates to start the high voltage charging.
