This range was delivered on 01/07/2021 (brand new in the box).  If the electricity goes out, you cannot use the oven. I clean my range daily.  I also clean under to range top just in case grease or food falls under there.  I NOW have to replace the left & right front burner tubes because they broke in half.  These parts are not cheap at all.  I would recommend another range that has copper tubing.
