• ** REMEMBER! **The microwave can still shock you even unplugged!!

    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

JVM3160RF2SS GE Over Range Microwave buzzes when door is closed

This GE microwave had blown a fuse and when it was replaced it blew again. I replaced the latch board assembly and switches. The microwave no longer blows the fuse but now makes a buzzing noise when the door is closed everything else is working. I saw one post which suggested replacing the circuit board but since the microwave is over ten years old it is probably not worth it. If it is a stuck relay is it possible to tap on it. Or if there is any other suggestion it would be appreciated. Thank you
I’ve seen a few do this and it was the board. Is there any way you can remove the user interface and let it dangle, shut the door and see if the sound is coming from the board? It will be quite obvious.
I let the interface dangle. When the door is closed the microwave is now operating even though I did not press start it is starting on its on when I plug it in. No noise is coming from the circuit board. When the door is open there is no noise and the microwave stops operating like it should normally.
