I bought this model to replace my previous Inverter which lasted 17 years.  I had used it regularly to bake cakes and was so pleased with it but the new one starts to burn the top of cakes within 10 minutes. Seems to me that it was a mistake to remove the rear element and use the grill with fan instead as heat coming from above is too intense.  Has anyone found a solution to this?  I am disappointed as I now have to use my conventional oven for baking cakes.
