My 20+ year old range no longer would light the stove-top burners - no clicking or spark. I resorted to lighting them with a handheld lighter. I could tell that the igniters were in bad shape; burned-on debris and some cracked. I took a chance and ordered 4 new igniters and installed them, replacing each of the old wires. The new wires were all the same color and length, but I made sure they plugged back in to the original location in the back. After reassembling and plugging it in, now all 4 burners click and ignite - no new range!!!
