Koshering an air fryer convection oven

Pesach

I have an air fryer / convection oven that I use mostly as a toaster and to air fry strictly veggies. I know the normal way to kosher a toaster is to put it on highest setting and let it get hot But there are different settings on it for different things. Would I just put it at highest temp on bake? For how long?

Also asking for a friend- if someone uses the air fry basket for meat or dairy, after they kosher it can they choose to cook either meat or dairy in it as if it was new?

Yes. Put on highest for fifteen twenty minutes. Until you know it reached the hottest.

And yes, once you kasher it, you can also switch between meat and dairy.
