Could be the magnetron, I suppose..
Why is my microwave not heating up?
This high voltage powers the magnetron to heat the food. If the diode burns out, the magnetron won't receive enough voltage to operate, preventing the microwave from heating. When the diode fails, it is often visibly burned out. Inspect the diode and if the diode is burned out, replace it.
Test the Magnetron:

It is normal to have a moderate sound, but if extremely loud it indicates trouble with the magnetron, should be returned for a replacement.

You need to remove the cover from the oven. Pull the plug first! Remove the Philips Screws. There are two special screws that are meant to prevent your proceeding further. No standard driver will fit these screws. You can remove them with small pliers gripping the outer edge of the screw and turning counter clockwise. If you are not familiar with capacitors, get somebody who is familiar. The light socket snaps in. Unsnap it. The lamp is taped to the socket with cellophane tape. I have never removed the lamp nor do I know the number. Do not plug in the oven with out the cover!!!!!
