Will you please send me the complete model number, so I can get information for you? It's printed on an i.d. plate that's located near the oven door, or behind the kick plate beneath the door.
OK. This is a problem that needs the attention of a professional service person, or an electrician. The breaker is tripping due to an over current condition, and the source of that will need to be diagnosed by someone who can be there with test equipment.
