Re: faulty double oven
The fan oven part of my AEG Competence 3210BU no longer heats up (the fan and light still work). Previously it was temperamental in that a dial setting of 200C took the temperature to 325C and a dial of 100C took it to 200C!!
Sounds like you element has burnt out due to a faulty thermostat, you could try repairs@ for a cost of the repair, or check the price of the parts using shop@. This may help you to decide what is the best options but I think without doubt the cost of repair will be a lot cheaper that replacing you oven, being that you would pay a minumum of £450 + to replace it
Hope This Helps
