So i was in my kitchen cleaning with earphones on. I was cleaning the inside of my microwave out with a wet rag, it was pretty dirty so i was workin' it pretty good. About a minute later I'm cleaning my oven right next to my microwave and i start to hear a weird noise over the music i was listening too on my earphone. Looked around didn't know what is was, pulled out my earphones and it was my microwave? pushed the open button it stopped and a few seconds later flashed F4. Now it doesn't work, and a couple lights remain on constantly on the display. Any one had this problem before, with either the weird noise or problem's after cleaning? Thanks Matthew
