My microwave stopped heating. Everything works except for the heat. Time, clock and the timer works as though the heat is on. Do I need a fuse?

All basic function seem to work except when I select the time and press start it starts but it will not heat up anything. I let it set for a few minutes before trying it again. When I set the time and press start I heard a click from inside behind the panel but it continued to run until the time expired. GE SpacemakerXL Microwave Oven, Purchased in 2005
