Morison,
The same thing happened to me about a week ago. I was preheating our electric oven, heard a very loud bang/pop. Checked and the oven had PF (power failure) I went downstairs and the breaker was tripped. Came back upstairs and to look at stove, the burners are working fine so I continued to preheat oven after a half an hour the oven was only slightly warm. Did you ever find out what was wrong?
