Product review (1 stars): Stainless Stains -AND- Bad Burner Valves
We bought this model in August of last year (2011), so tomorrow the warranty regular warranty runs out. I already have an extended warranty from the dealer where I bought the range. The first problem we had with this range occurred about a week after installation. The cooktop grates started rusting. There were rust spots on all three grates. They were replaced within a week. However, two of the replacements had to be returned because of cracks along several of the grate bars. They were actually broken and had to be returned. The next problem occurred about a month ago in July when the right burner got stuck and wouldn't turn on. The authorized repair company had to order the part and we had to wait a week. In the meantime, we could still use the range. Yesterday the left burner valve wouldn't turn off after cooking food. I tried to jar it loose, then tried to turn the stem with a pliers, but it would NOT turn off at all. With gas shooting out the burner, I had to pull the range away from the wall and turn the main gas valve off, now rendering the entire range useless. The repair guy can't get out for another week, and then it'll take another week to order and get the parts. That means we can't cook for two more weeks.
  I have the same problem as RJ of Cambridge with stains on the stainless steel. None of the stainless steel cleaners available seem to work.
  This range has been a big disappointment, which is a shame because Kitchen Aid is supposed to have a good rep. I expect more problems in the future, so the extended warranty will come in handy.
