If you can light the barbecue with a match you may have an ignition switch problem. Check your igniter switch. Is it making a clicking noise? If the igniter does not click, it is not aligned correctly with the grey rocker switch. To align it, remove the control panel (consult your owner’s manual for instructions). Once the control panel is removed, check the position of the igniter. It should be tightly secured with the lock nut in the smaller hole of the keyhole frame. If the igniter is aligned properly, make sure the control panel is not loose. There should be two fasteners holding the panel in place.
Next, check to see if the igniter wires are loose. The white and black wires should be secured at both ends. Then check the position of the metal tab protruding from the cooking box where the white wire attaches. This tab must be 45 degrees away from the cooking box to avoid a shorted spark.
Finally, very humid or rainy weather can cause moisture to collect on the end of the probe and make the igniter unable to spark. To remedy this condition, light the barbecue with a match. The heat from the barbecue will warm the probe and should fix the problem.
If you cannot light the barbecue with a match you probably 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.
