Oven temperature fisher paykel

Question

Hi

I have a fairly newest electric oven fisher and paykell, it has two k***s a temperature k**b and select your bake k**b. (2.5 years old)

The fan force and fan bake doesn't heat up at all, although the grill seems to work and the bake.

I do recall seeing a blue flash one night when my husband was cooking, could that have been a fuse or something?

Thanks
