Gas BurnerNo burner will light with a match or ignition

Check the LP gas bottle:  It may be empty or have a faulty connection.  A bottle with gas normally makes a liquid sound when shaken.  Otherwise, try another full gas bottle.

Check the regulator:  Particularly if the barbecue has not been used since the last season.  It may have an obstruction such as a spider nest or debris inside.  Otherwise have the regulator checked or replaced.

Inspect the burners:  Remove the burners and check inside them for any obstruction.  Insects and spiders are known to hide or even nest inside the burners or venturi tubes.

Check the gas jets and hose:  There could be obstructions in the gas jets or hose.  Check the hose is clear of insects, water and debris, particularly if the hose was detached from the barbecue or regulator since its last use.  Remove the burners to reveal the jets and push a pin into each jet hole to clear any obstruction.

Control knobBurner will light with a match, but not using the ignition system

Check electrode wiring:  Check that all the electrode wires are attached and firmly connected.  Check the instruction manual for the correct wiring, especially if multiple wires are disconnected or the barbecue was just assembled.

Does it use a battery?  If the barbecue does not make a loud thud sound when the ignition button is pushed, then it uses a battery.  Replace the battery with a fresh battery as follows:  If the electrode wires come into an area behind the cabinet door, the unit takes a 9V battery as used in smoke alarms.  Otherwise it uses an AA or AAA battery that is located behind the ignition button, which be accessed by unscrewing the base section of the button.

No ignition button:  Try different control knobs, as the intra-spark ignition may only apply to certain burners.  On a few models such as the Companion series, only the far left control knob lights the burner.  Once one burner is lit, the rest are lit by turning on each control knob in sequence from the burner that is already lit.

Gas RegulatorLow flame or flashback

(fire in burner tube – a hissing or roaring noise may be heard)

The LP gas bottle may be too small:  If the bottle is too small, it will not provide enough flow to run all the burners, particularly when using butane gas and the outdoor temperature falls below 10°C.  Use a larger bottle or consider switching to propane gas (requires a propane regulator.)

The burners may have obstructions:  Remove each burner and use a pipe cleaner to ensure the burner and its port holes are clear of any insects or debris.  Insects and spiders are known to hide or nest inside burners, particularly when not used since the previous season.

Check the gas hose and jets for obstructions:  If the gas hose was disconnected from the barbecue or regulator since its last use, it may have debris, condensation or an insect inside that is obstructing the gas flow.  Clear the gas jets by removing the burners and inserting a pin into the hole of each jet.

It may be too windy:  Move the barbecue to a more sheltered position.  A strong breeze may also lead to uneven cooking or poor heat retention while roasting meat.

Gas valve knob difficult to turn

The gas valve (or integral ignition) is jammed:  The gas valve needs to be replaced.

Excessive flame size, burners do not extinguish when the gas valve knobs are turned off

Check the regulator:  It may have frost damage.  Have the regulator checked or replaced.

If the barbecue has not been used since the last season, moisture may have frozen inside the regulator.  Frost damage can lead to the intense gas bottle pressure being delivered to the barbecue, which the gas valves and seals may not withstand.

Problem prevention

Check the instruction manual for advice on operating and maintaining barbecue, particularly the section “Care and Maintenance“, as most faults are caused by improper care or storage, particularly when stored over an extended period of time.
