all 4 electric burners getting too hot

When putting my electric coil type burners on high all the sudden they are making the top of the stove so scorching hot that it burnt me. The oven fan even came on!
I thought that maybe it was just the one burner but last night I went to boil spaghetti on the smaller burner and it got the stove top so hot I had to shut down the stove as I was afraid of a fire. Thank you for any help you can give me.
