Kenmore range made loud bang and now no power to the oven elements

Last night my Kenmore range made a loud bang and blew the breaker to the range. I reset the breaker and the stove top works but not the elements in the oven. The light comes on saying the oven is heating up but the elements never heat up. I have been on the phone with Sears and what a joke. I cannot find a model number anywhere on my range. The one woman told me I purchased it in March of 04 and the model number is 79072682300. I tried using that model number and couldn’t find anything online.
