My Openevse charger is about 16 months old. It has just started producing a loud noise when charging. Apparently 366Hz. It's charging ok and not getting noticeably warm. If I stop and restart charging the noise goes away, at least for a while. It sounds like a buzzer but I don't think there's a buzzer? "Safety" menu shows "No Ground" count of 1. Everything else 0/ok.
