Why is my electric Dacor ER30DSRSCH/NG oven not heating up?

Why is my electric Dacor ER30DSRSCH/NG oven not heating up? My model# is ER30DSRSCH/NG. I got it brand-new, but an old stock. Just right after 1 year, the oven doesn't heat up. I tried both bake and cleaning mode. I can hear the clicking sound every 1-2 mins. I tried to reset the fuse by pushing the red button. It didn’t have the click sound. So, I bought the same fuse thermostat from Ebay. Unfortunatley, it didn’t fix the problem. What is the possible issue here? Please help. Thanks
