SOURCE: Panasonic Dimension 4 Turbo Bake
Your Magnatron is most likely to have failed, its an expensive part and on a turbo 4 could be 2M236-M42. Unfortunatly this appears to fail due to reduced air flow. So if you do replace it I would clean the rear grills completely to increase the airflow within the oven.

SOURCE: Microwave won't heat food.
My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help

With the symptoms you
have, I would most strongly suspect a shorted high voltage rectifier
diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.
The diode is a fairly cheap fix, and the mag will cost more.
If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.
Here are some links you or someone you know can use for test help, but read their safety warnings first:

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
