If it’s like mine then it’s a low speed fan on “bake” mode which has little impact on cakes. If you have a convection option, don’t use it when baking.
The only options are fan forced, grill with fan and grill without fan. I might try the grill option and put some foil on a rack above the cake to stop the top from burning. I’ve had to do this for many years as my last two ovens only had functioning grills.
I have never had a properly functioning oven before and now my brand new one is still wrong. :(
What is the model number? So I know what not to get.
