I love my new oven.  Once you get to know which “buttons” to hit it very easy to work. Heats to the right temperature.  It could have come with an owners manual, then it would have been easier to figure out how to work.  I downloaded from the Internet, but miss the ones we use to get with appliances.  Had to search  for what I wanted to know.
Steam cleaning should only be used for things not baked on.
