Question

l have a siemens oven which stopped working yesterday.I don't have a model make for you but what happened was the oven was on then the electricity tripped.I think it was the oven that did it because now there is no heat coming from it but the light inside the oven is working and also the smaller oven/grill is still working above.Please could you advise me on a solution.
