We have a 4 burner Viking gas stove with griddle that is 7 years old. There is no oven or broiler with is unit. In past week we have had a problem with the right front and rear burners, but NO problem at all with the left front and rear burners. When you tuRn the knob on the front burner it clicks and lights right away, but when you try to light the right ear burner while the right front is lit and burning - no click or spark and the burner will not light. The same in happens when you just light the right rear burner, it clicks and ignites but when you then try to light the front right burner, no clicking or ignition. Again, the left front and rear burners do not have this problem and it only began to be a problem about a week ago.
