Power outage occurred and now the machine does not operate. Is there an internal fuse?

There are two fuses, checked them both and they are both OK, the machine still does not work. Any other suggestions?

It is not just that the microwave doesn't work. When the machine is plugged in the panel lights do not go on. Would the door microswitch effect that function?

The switch does 2 functions:powers up the mag when the door is shut and turns the light on when you open the door. Since the control panel appears to be dead you need a schematic to see where the power comes from. There may be more fuses.
