Buzzes like an alarm clock when door is opened or any button is pushed; cook, fan, clock, etc.
The buzz comes from behind the control panel from a component (RY04) on the board. Its a short black rectangular block. One of 4. Also the large component that looks like a motor winding gets warm.
Things seems to function (sort of). The microwave seems to turn on, the plate rotates, but the buzzing is always there.
Do I need to replace the entire board?
