Removed burner, drip pan and lifted top. Noticed one of the wires in the receptacle had burned. Ordered new receptacle and replaced. Still did not work. So I just ordered an infinite switch hoping this fixes the problem. Also ordered 4 new drip pans and they fit like a glove...stove top looks like new. If the infinite switch does not fix the problem then I'll just have to purchase a new stove. I love this Whirlpool stove. It has a stainless steel cook top but it is 16 years old.
