Okay this is my fault I was reheating some fast food and did not realize the sandwich was wrapped in foil paper. It looks like the microwave completed the reheat cycle and died. yes it sparked and there a small amount of black smoke inside the unit. there is no power to the unit but I do have power coming out of the wall. no lights or lcd on microwave. I took the control panel off the front and remove the small white ceramic fuse and verified that it is good it has continuity so it's not the fuse. whats next to check.... thanks
