My microwave sparked I put my mug which has a golden handle by mistake in the microwave. Then the microwave sparked so I disconnected the microwave. Is the microwave still safe to use? The microwave is only 3 months old.
In the past I made such a mistake multiple times with the same microwave... the one I still use to this day.
So if the sparks from the golden part of your mug was the only incident, I believe your microwave is just fine.
