It was getting overly hot before the fuse first blew out, someone mentioned a magnetron?
Just to clarify: With the door closed, the fuse will blow as soon as you plug the unit in? Have you checked all three microswitches? One acts as a crowbar.

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.

SOURCE: top of over-the-range microwave hot to touch; normal?
A little over 100F is hotter than most folks can stand to touch, so it may not be seriously hot.
But if you're concerned, you might see if your dealer will let you test another one or a similar model at the store to see if it also gets that hot.
Otherwise, you can return it to be safe or you can contact Panasonic consumer electronics support here or at 1-800-211-7262 to ask them about it.

The light is the only thing that comes on when you open door. You either have a shorted door switch (Micro switch) or a shorted bulb. You have either a shorted bulb or bad socket. From my experience, it's the bulb. Just because it may seem to start to come on when you open the door, it's most likely bad. At least it not expensive.
