JennAir Microwave worked one minute then won't the...

Question

My JennAir just quit working last night. The control panel still works. The time is displayed and you can select a cook time but the microwave never comes on when you hit the start button. The timer begins counting down the time and the light comes on, but nothing happens. Any advice would be much appreciated. I saw someone else had this probloem but I didn't see any answer. I would greatly appreciate any suggestions you could give me. My husband put in a new timer when it went out but neither of us know what this could be. Thank you for any help you might could give us.
