Query: Very Dangerous Appliance

Do not buy this appliance. Even one star is over-rated. My wife has already burned herslf several times as the hot wire rack literally flew out of the oven. This happens if you pull the rack about 1/3 of the way out of the oven to remove hot food. Also, when non-convection baking for longer than 20 minutes, the convection fan comes on by itself, but the fans blades sound like a scraping on something, making a ringing noise. We bought this oven to replace a DeLonghi that failed after 2 years, big, big, mistake in not buying another DeLonghi.
