I have a Whirlpool electric range RF263LXTQ2- 2 yrs old-it gets so hot that the large burner pans are both charred black. Had it looked at about a year ago and couldn't find any problem-top and front of stove get so hot when the oven is on you can't touch the stove-large burners are tipped to the center of the stove so any liquid runs to that side of the pan-for the past two weeks the large front burner control has a sparking sound when you turn the knob to start the burner-the two small burners seem to work fine and the drip pans are not burned like the large ones--today I was going to take the stove apart to clean it and had the oven on before-I couldn't even take the burners off the stove because they were so hot and the top of the stove was so hot. I would appreciate any help in figuring out why this stove gets so hot-I am afraid it can cause a fire.
