I have a 30" KitchenAid gas range and am having trouble after trouble with the oven. The "factory approved" technician has made 5 trips so far, even took the thing away and gave me a loaner (cheap version that worked! I wish I had that now). The thermometer, control board, relay switch, and overlay to name a few items were replaced to no avail. After they brought it back from the shop because they could find nothing wrong with it, I reluctantly tried to bake something and the same thing happened again: The oven goes into pre-heat mode, should pre-heat in 6 to 7 minutes but after 1.5 hours, was at 290. Obviously I am sick of this. The usual lousy service from KitchenAid who does not stand behind their products combined with the inability of the technician to do anything about it has me sick and tired of this beast. I am ready to get rid of it and look for something else. Unfortunately I'm restricted to a 30" gas range. Please let me know what you might recommend.
