    I have the same, all the key pads and timers work it lights up, spins but does not heat up food it is only 2 years old.  I had a repair man look at it but he could not find problem without taking it off wall which he does'nt do and my wife had to let him go without resolution.

    When you hit Start to
    cook, do the inside light and turntable come on?




    Any unusual noises? Is
    it louder or quieter than usual?




    Do you have the model number?



    These answers will help
    me judge whether it's in the high voltage
    section (magnetron, transformer, or diode) or the control section
    (door switch or control board relay or connection).

With the symptoms you mention, I would suspect:

- loose or corroded connection at the magnetron
- bad magnetron
- shorted high voltage diode

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

SOURCE: microwave works but is not heating up food

can you hear the magnetron operate i.e. light dims,transformer has a louder hum,if so more than likely either the H.v. diode or H.V. capacitor is bad or worst case scenario the mag tube has failed.....costly

Food in microwave is burning on edge and cold in the center


you may find the old unit was lower watts so took longer & cooked/heated better all the way through. a way to fix this is lower temp settings or pause and stir the food to help heat it up more even.

I have kitchen aid microwave modelkcms185jss starts runs fine but does not heat food at all.


Does not heat food means a problem on magnetron tube and fuse blown in high voltage area. Have it replaced and it will heat again.
I hope I answer your problem.

Perhaps the "repairman" should take another look at it. A lot of microwave ovens have an aerial that directs the energy out to the load or food to be heated.
Maybe...maybe not but worth a look behind the waveguide cover I would say.
