Electrolux Double Oven "Bangs" and trips Cooker sw

[gerokinn]

When our Double Oven heats up it is causing a loud bang just under the hob and trips the cooker trip switch....the oven is about 3 years old.
Wanted advise whether it is actually the cooker ie element or whether its the cooker switch on the wall that is causing the issue. Not sure whether to get an electrician or a service guy for the cooker ?
Any advise please ?

I imagine from what you describe a service guy will be a better port of call.
