Igniter engages (clicking), but doesnt light burner. Why?
Of the 4 burners on our stovetop only 1 will still ignite properly when the corresponding knob is turned to light it; we use a trigger lighter to light the rest. The electric igniters are all firing great (clicking is uniform and constant), but the burner will not light. Replacement parts for our Sterling GCT360 are not available I'm told.
