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.

I am going to keep an eye on it. It may have done it in the past but this is the first time I have noticed it buzzing. It did not get hot and it was charging normally and no error lights. I will keep using it until it breaks and I am pretty sure it would be out of warranty being just over 3 years old. When I touched the unit I could not feel any vibration so it is nothing loose in the unit.

Probably similar to what a florescent fixture does to make its buzzing sound.
