Spark is arriving; gas or the burner cap is not.
If the igniter is clicking, the spark module and the switch under the knob are both alive. Nine times out of ten it is a burner cap sat a millimetre off its seat, a blocked port ring after a boil-over, or a clogged igniter tip. Pull the cap, line it up square, and dry everything properly. If it still clicks with no flame and the other burners light, the fault is at that burner orifice or the valve behind it.
- Check first
- Lift the cap, check the ports are clear, seat it flat and dry.
- Call us if
- All burners click at once, or you can smell gas with nothing lit.
