Loss of Shore Power

Thanks all for your input. As it worked out the 50 amp shore power was miss-wired. There was power at the pedestal and I assumed it was clean power. It was not. The miss-wiring caused an over-voltage to the system which fried an alarm clock, a personal fan, and most importantly the installed microwave. The microwave is now acting really strange. There is no "display" illuminated and the buttons do not respond but when I open the door, the interior light comes on and the turntable rotates... No trouble shooting information provided by the manufacture. I'm hoping there is a blown fuse internal to the microwave. I will have to remove it to find out.
