Gas burner clicking but not lighting: causes and fixes

Few kitchen sounds are more irritating than a burner clicking over and over without lighting. The upside is that this particular symptom is one of the more homeowner-friendly problems on a gas range, because the most common causes are dirt and moisture rather than failed parts. Work through these in order before assuming something is broken.

Dry everything thoroughly after cleaning

Water in or around the spark electrode is the number one cause of continuous clicking, especially after a spill or a wipe-down. Turn all knobs off, remove the burner cap and head, and let the parts air dry completely or use a hair dryer on low for a few minutes. Many ranges start behaving normally within an hour once moisture evaporates.

Reseat the burner cap correctly

Burner caps sit in a specific orientation, usually with a notch or pin that keys into the burner head. A cap that is rotated slightly or riding up on a food crumb puts the gas ports out of line with the spark gap. Lift the cap, wipe the mating surfaces clean, and set it back down so it sits flat and does not rock when nudged.

Clear the burner ports

Boil-overs bake into the small holes around the burner head. Soak the head in hot soapy water, then clear each port with a straightened paperclip or a sewing needle. Do not use a toothpick, since the tip can break off inside the port. Never use a drill bit or anything that could enlarge the port, which changes the flame characteristics.

Inspect the spark electrode

The electrode is the small white ceramic post beside each burner with a metal tip. Look for a cracked ceramic body, a carbon-fouled tip, or a bent electrode that has moved too far from the burner head. The spark gap should be roughly an eighth of an inch. A cracked electrode leaks its spark to ground and needs replacement, typically $150 to $250 installed.

When one burner clicks, they all click

On most ranges, a single spark module fires all electrodes at once, so a fault on one burner makes every burner click. If the clicking continues even with all knobs off, a switch is stuck closed or the module has failed. Unplug the range to stop the clicking, then call for service, since a continuously sparking module is a real hazard around gas.

Gas supply and burner valve issues

If the burner clicks with a good strong spark but no gas ever ignites, and other burners work, suspect a clogged orifice or a valve that is not opening. If no burner lights, confirm the range shutoff valve is fully open and that other gas appliances in the home still work. A range that was recently moved may have a kinked connector.

Know when to stop

Cleaning, drying, and reseating are safe DIY work. Removing the cooktop to access the spark module, replacing electrodes, changing orifices, or adjusting anything on the gas manifold is technician territory. Any of those tasks involves live gas connections and a spark source in close proximity.
