My maytag combination gas/convection range is an inferior product. The aquafor cleaning system does not work and you must manually clean with baking soda and a lot of work. Additionally as I was preheating the convection to 375 degrees at 275 degrees the interior of the oven door (glass) splintered into thousands of pieces. In talking to customer service and a supervisor, a three year old pricey range is not waranteed for a splintering glass oven door -talk about pride in a product. I've decided to scrap it rather than repair as the next thing that it blows up might be my house and me.
Don't buy a Maytag or Whirlpool appliance unless you're masochistic!
