Can you post the full model number please. It should be on a sticker on the oven cavity when you open the door.

Ok thanks for that.
Yes you should feel a draft from the top of the door on this oven when its in use. As the draft is the cooling fan blowing air around the oven and doors to keep it cool while the oven is in use. Otherwise what happens is the oven controls over heat and cut out stopping the oven from working.
So that's normal what you feel when its on.
If you need anymore info just get back to me.
when i put things in the oven to cook it always takes longer 10 to 30 mins over recomended time
What oven setting do you use?
Is it fan assist or convection mode?
