The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck

With the symptoms you
have, I would most strongly suspect a shorted high voltage rectifier
diode, a bad magnetron, or a bad high voltage diode.
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.
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.
Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted, it's probably okay)
You can contact your manufacturer about parts by consulting the contact information in your owner's manual.
If you have no manual, I would suggest calling the dealer where you bought it to see if they have a number for the mnaufacturer.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: Food won't heat up
Hello, I had the same problem, and just fixed mine. Start by turning on your microwave (on mine, the light turned on and timer worked, but the fan nor the plate turned)... push the door upward and see if the microwave turns on... (mine did). so far so good. open the door and take the upper hinge cap off with flat head screwdrive. take the door off and place a small washer on the bottom hinge, put the door back on. your microwave should be good now. essentially, the door just needs to be pushed up a bit so it will work.
good luck, hope that works for you...

When the microwave works properly but just doesn't heat, then the magnetron is bad and will need to be replaced. You can get the part and the diagram at partselect . com or repairclinic . com
