Hi, we have a GE Profile 5-burner gas cooktop. The front left-hand burner is having some sort of ignition problem. The gas turns on, but the burner won't light on it's own. However, when you turn on the burner directly behind it and at the same time turn on that front burner, they will both light up. But when you only turn on the problem burner, no clicking sound and no lighting up, just gas is on. I either have to turn on the 2 burners at once or use a lighter to get the burner to light up.

Any ideas as to what is the problem?
