Ignitor 'Spark' knob not lighting stove
We have a 2003 Jayco Feather 23B. It has a stove with three burners. Since we bought it, we've had no problem getting the stove to light using the 'Spark' knob. Of course we first get the air out of the lines, turn the burner to 'Lite', and then turn the Spark knob until it lights. This last trip, though, it wasn't lighting. You could see a small spark at each burner but none of them would light. Gas is definitely coming out and we eventually just grabbed our BBQ lighter and lit it that way, but I'm curious why the 'Spark' knob would just stop working. Anyone run into this before? I'm guessing there's a contact that's dirty or something out of alignment somewhere, but before I started taking things apart, I figured I'd ask here as I'm guessing someone has had to have had this problem at some point.
Thanks in advance.
