My microwave is not heating--

Question

My microwave is not heating-- the control panel seems to work-- you punch in the buttons and it starts counting down the minutes, but nothing happens except for the clock to count down. The model # is JES1358WL 01. The serial # is TL 923197 U. I do not give my permission to use my email address for anything other than advice for this problem --thank you---mtopper
