The main oven on by Belling dual oven elec cooker appears to cook at max temperature only - all food is burned. Is it the thermostat? Its a bit pricey to change if that is not the problem!
most likely your thermostat causing your problem.
google your make and model number and you should find a supplier who can get one for less than belling will charge.
hope this helps :)
