To ignite your gas BBQ, push in the button and turn it to high (while keeping the button pushed in), hold it for a few seconds to let the gas flow find the spark. Then let go of the button.
It could be 3 things:
1. The Gas
Make sure it is turned on and that your gas bottle is not empty.
2. The igniter
If you can light the grill with a match you may have an ignition switch problem.
- Check to see if the igniter wires are loose.
- Check if the probe is dirty, clean it with a sanding sponge.
- Check if the probe is wet. In this case light the BBQ with a match, the heat will dry the probe and fix the problem.
3. Snap Jet Igniters
When the control knob is turned from off to high, a spark is created. This may need to be repeated 3 or more times to ensure ignition. If the igniter has a spark, but the burner tube will not light try removing the grates to see if the igniter is sparking. If a spark can be seen, but the burner tube still will not ignite, the electrodes may be dirty. Gently clean the electrodes with a tissue. If igniter does not spark check to be sure all the wires are hooked up properly.
If you cannot light the grill with a match you may have a gas flow problem. Have you cleaned your burner tubes recently? It is very important that the portholes of the burner tubes are clear of any blockage. If the gas flow is restricted, the igniter will struggle to light. To clean your tubes, brush the portholes with a steel wire brush in an up and down motion. This cleaning should be part of your routine maintenance.
