Oven light trips electric?

My samsung electric oven operates in all ways except that when the oven light comes on (either by switch or by opening door) it trips out the electric in my house. I have a new fuse box in the house (only 2 weeks older than the oven) so I am sure its not that as it worked fine till this week now I can't cook. Is there anything I can do or do I HAVE to pay the ridicules call out fee for a samsung engineer to fix a light???
