If you notice vapor being exerted from the top sides of the oven near the vents, that is most likely steam. If you notice a vapor that is much darker and has no opacity (meaning more difficult to see through), that is most likely smoke.
Sometimes food smokes when being overcooked or when a lot of oil is used.
We recommend reducing the oven temperature, opening your windows, and let the fans in your oven cool it down. Once your oven cools down, use a warm damp cloth to clean the interior walls, ceiling, and floor.
