I hope that the photo shows up on this post, because it shows the problem better than a written description could do. Two of my stove dials,when turned off, and locked into the "off" position, the word, "off" on the dials, do not align with the vertical marker above the dial. One dial, when locked in the off position aligns midway between High and Off. And, the other one aligns with Lo under the vertical indicator mark above the dial. How can I get this problem corrected?
