So it's dead? (No display, no inside lights, no beeps?)
A microwave can be dead for many reasons.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.
If it's random, it may be a bad connection, usually on the control board or fuse holder.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

I have the same problem every time I use the oven for a long time and then use the micro.
Solution is simple, yet unbelieveable.
This is a toggle switch. It is located on TOP of the oven box.
It is almost impossible to reach...but once reached, all you have to do is push it and it resets the micro.
1-remove the "frame" around the micro.
2-pull the micro out (use 2 people) far enough so that you can reach your hand - or I use a wooden yardstick- to toggle the thing. It is VERY tiny.

It's either the fuse or the thermostat on the magnetron.
