A gas stove that clicks and will not light has a spark and no flame, which means the gas is not meeting the spark. The usual reasons are a burner cap that is not seated, a burner that is wet or dirty, blocked ports, or no gas arriving. A stove that does not click at all has lost its ignition power. A stove that will not stop clicking has moisture in its switches. Those are three different faults, and telling them apart is the first step.
This guide starts with safety, because clicking without a flame can mean unburnt gas. It then sorts the fault by pattern, gives the checks you can do safely in order, and explains what each part does so that you know where to stop. It covers gas hobs, freestanding gas cookers, table-top stoves and gas ovens, on cylinders or piped gas. For a repair, see gas stove repair in Dubai.

If you smell gas at any point, go to the next section before anything else.
Each press of the igniter with the knob open releases gas. If it does not light, that gas is in your kitchen.
1
Stop. Do not click againAnd do not touch light switches, the extractor, sockets or anything else electrical. A switch can spark.
3
Close the gas at the sourceThe cylinder valve, turned clockwise until it stops, or the isolation valve on a piped supply.
4
Open windows and doorsLPG is heavier than air. It sinks and collects at floor level and in low cupboards, so open low as well as high.
5
Leave the kitchenAnd use your phone outside it.
6
Do not go back to the stove until the smell has clearedAnd do not reopen the gas until the cause has been found.
Try to light a burner for a few seconds only. If it has not lit after two or three attempts, turn the knob off and wait at least a minute before trying again.
Never look for a leak with a flame.
Never tape, wedge or hold down a knob to defeat a safety device.
Work on burners only when they are completely cold.
Unplug the stove, or switch off its socket, before you clean round the igniters or the knobs.
A yellow, sooty flame means poor combustion. Do not use that burner until it has been put right.
Home checks stop at the removable burner parts. Jets, valves, igniter wiring, thermocouples and regulators are not home repairs.
Most stoves that click without lighting have a harmless cause. The danger is in the habit of clicking again and again with the gas on, then reaching for a lighter.
PartWhat it doesWhere it isHome part?

Regulator and hose, or the piped supplyDeliver gas at the right pressureAt the cylinder or the wallCheck only
For a burner to light, gas has to leave the jet, mix with air in the burner, come out of the ports nearest the igniter, and meet a spark there. Take any one away and you get a click and no flame. On most stoves, pressing one knob makes every igniter spark together, since they share one generator. That is normal.
Before touching anything, try each burner in turn for three seconds and note four things: does it click, do you see a spark, do you hear or smell gas, and does it light.

One burner affected. the fault is local to that burner.
All burners affected. the fault is shared, which means gas supply or ignition power.
Works with a match. the gas side is sound.
Fault appeared straight after cleaning or a spill. moisture or a misplaced part.
In a dim kitchen you can see the spark clearly. It should be a crisp blue-white tick from the igniter tip to the metal edge of the burner cap or ring. A spark jumping sideways to the hob top, or along the ceramic, is in the wrong place.
If no burner lights and you neither hear nor smell gas, there is none arriving.
SupplyCheckFix
LPG cylinderIs the valve on top fully open? Is the cylinder empty? Lift or rock it: an empty one is light. Frost or sweating low on the cylinder shows the liquid levelOpen the valve. Change the cylinder
Is the regulator seated and locked on? Clip-on types have a lever or switch that must be in the on positionReseat it. Switch it on
Is the hose kinked, trapped behind the cooker or crushed?Free it
Has the regulator's safety cut-off tripped? Some shut off if the hose is disconnected or the flow is too highClose everything, wait, reopen slowly. Follow the regulator's instructions
Piped gasIs the isolation valve by the cooker open? The handle lies along the pipe when openOpen it
Is the building's gas on? Ask a neighbour or the building security. Supplies are shut for maintenance or after an alarmWait, or contact the building's gas company
Has a gas detector or safety shut-off valve in the kitchen tripped?Follow the building's procedure. Do not force it
EitherAfter a cylinder change or a shut-off, air in the lineHold a burner on for a few seconds longer than usual, two or three times, with a window open
If the others work and one gives a click and nothing else, with no hiss at all, its jet is blocked or its valve has failed. A blocked jet usually follows a boil-over that carried food down into the burner base. That needs the jet removed and cleaned, which is a technician's job, because the jet's hole is a calibrated size.
Small flames on every burner, slow to light, point to low pressure: a cylinder nearly empty, a failing regulator or a kinked hose. Try a full cylinder before anything else.
Check 2: burner cap and ring
This is the fix more often than any other. After cleaning, the ring and cap go back slightly wrong, the gas comes out in the wrong place, and the spark has nothing to light.
1
Wait until the burner is cold, and turn the knob off
2
Lift off the pan support, then the cap, then the ringThe cap is the flat enamelled disc. The ring, or crown, is the aluminium or brass piece beneath it with the slots round its edge.
3
Look at the baseYou will see the igniter, perhaps a thermocouple, and locating pegs or notches.
4
Refit the ringIts notches or pegs must drop into their slots. There is only one correct position. It should sit flat and not rock. The gap in the ring usually goes round the igniter.
5
Refit the capCentred, flat, not tilted. Run a finger round its edge. It should be the same height all the way.
6
Check you have the right parts on the right burnerCaps and rings come in sizes. A small cap on a medium ring, swapped during washing, looks nearly right and will not light properly.
FaultEffect
Cap tilted or off centreGas escapes on one side, away from the spark. Lopsided flame or none
Ring not on its pegsRocks. Ports not aligned with the igniter
Ring upside downPorts blocked against the base
Cap and ring from different-sized burnersPoor seal, yellow uneven flame, hard to light
Cap warped or enamel chipped at the edgeGas leaks under the cap. Replace it
Wok burner inner and outer parts mixed upInner ring will not light
Take a photo of each burner before you lift it apart to clean. It settles any doubt about which part goes where.
Water is the commonest reason a stove stops lighting straight after it has been cleaned, or after a pan has boiled over. A wet igniter shorts its spark away, and water in the burner ring blocks the ports.
1
Switch off the socket or unplug the stove
2
Take off the cap and ringShake them dry and wipe them.
3
Blot the burner base and the igniter with kitchen paperGet into the well round the igniter.
4
Leave everything apart to air-dryAn hour in a warm kitchen. Longer if a lot of water went in. A hair dryer on a low, cool setting speeds it up. Not a heat gun.
5
Refit carefully and try again
If the burner lights after drying, that was the whole fault.
If it lights weakly with a spluttering or hissing flame, there is still water in the ring. Let it burn off on a low setting, or dry it again.
After a sugary or starchy boil-over, drying is not enough. The residue blocks the ports as it hardens. Go to the next check.
Clean a hob with a wrung-out cloth, not a wet one, and keep liquid away from the base of the knobs.
Check 4: blocked ports and a dirty burner
The ports are the small slots or holes round the edge of the burner ring where the flame comes out. If the ones nearest the igniter are blocked, the spark has no gas to light even though the rest of the ring is clear.
1
With the burner cold and the gas off, remove the cap and ring
2
Soak them in hot water and washing-up liquid for 20 minutesLonger for burnt-on deposits.
3
Scrub with a nylon brush or an old toothbrushNot a steel scourer on aluminium rings.
4
Clear each portWith a wooden toothpick, a pipe cleaner or a soft brush. Work from the inside outward so debris leaves the ring.
5
Rinse and dry completely
6
Wipe the burner base with a barely damp clothDo not flood it. Keep water out of the central hole, which is the jet.
7
Refit and testThe flame should be blue and even all the way round.
Flame after cleaningMeaning
Blue, even, quietGood
Gaps in the ring of flamePorts still blocked at those points
Yellow tips, soot on pansStill dirty, cap misplaced, or the burner is on the wrong jets for the gas
Flame lifting off the ports with a roarPressure too high or wrong jets. Technician
Small flame, clean burnerJet partly blocked, or low gas pressure
Lights at one point and creeps slowly roundPorts partly blocked, or a cross-lighting slot blocked
Do not push pins, needles or wire into the jet hole. It is a precise size and is easily damaged or enlarged.
Do not use oven cleaner on aluminium burner parts.
Do not put caps and rings in the dishwasher unless the manual says you may.
The igniter is the small metal pin sticking up beside the burner in a white ceramic collar. It needs to be clean, dry, intact and pointing at the burner.
2
Look at the tipIt should be bare metal. A crust of burnt food or a film of grease insulates it.
3
Clean it gentlyWith a dry toothbrush or a cloth with a drop of rubbing alcohol. Brush upward. Do not bend it.
4
Look at the ceramicA hairline crack lets the spark escape sideways into the hob. A cracked igniter needs replacing.
5
Check its positionThe tip should sit close to the burner ring, typically a few millimetres from it, level with the ports. If it has been knocked over or pushed down, do not force it back. Ceramic snaps.
6
Switch on and watch the spark in dim light
What you seeMeaning
Crisp spark from tip to burnerIgniter is fine
Spark jumping from the side of the ceramic to the hobCracked ceramic, or a track of dirt or moisture down it
Weak orange sparkDirty tip, low battery on battery stoves, or a failing generator
No spark at this burner, others sparkThis igniter, or its lead, has failed
Spark at every burner except with one knobThat knob's switch
No spark anywhereNext section
Igniters and their leads are replaced from underneath the hob top, which means lifting it or removing it. That is a technician's job.
If pressing or turning the knob gives no sound and no spark at any burner, the ignition has no power or its generator has failed. The gas side may be perfectly good. Try lighting a burner with a match or a long lighter held at the ports before you turn the gas on.
Stove typeCheckFix
Mains-powered ignitionIs the plug in and the socket on? Test the socket with something else. Has a breaker tripped?Restore power
Is there a separate fused switch for the cooker's ignition?Switch on. Check the fuse
Battery ignitionFind the battery holder: under the hob front, behind the kick panel, in the oven drawer or beside the cylinder compartment. Usually one AA or a D cellFit a new battery the right way round. Clean the contacts
Piezo ignition, on table-top stovesA mechanical click from the knob itself with no electricity. If the knob turns with no snap, the piezo has worn outA repair, or light by hand
Separate ignition buttonPress it while turning the knob. Some stoves need bothUse both
AnyAfter a spill or wet cleaning, the generator may have shut down or shortedLeave unplugged to dry for a day
AnyPower proven, still silentSpark generator or the switch harness: technician
A battery that is low gives a slow, tired click before it gives none. If the clicking has been getting slower for weeks, change the battery.
Igniters that carry on clicking with every knob off are being told to spark by a switch that has stuck closed. The cause is nearly always moisture or sticky residue in a switch under one of the knobs, after cleaning or a boil-over.
1
Switch off the socket or unplug the stoveThe clicking stops, and so does the wear on the generator.
2
Pull the knobs off, if they pull off easilyMost do, straight toward you.
3
Dry round each spindle with kitchen paperAnd wipe away any spilled food.
4
Leave the knobs off and the power offOvernight, or for a day in humid weather. A fan or a hair dryer on cool, aimed at the spindles, helps.
5
Refit the knobs, switch on and test
ResultMeaning
Clicking has stoppedIt was moisture. Clean with a drier cloth in future
Stops, returns the next time the hob is wipedLiquid is still getting in. Use less water round the knobs
Still clicking after a full day's dryingA switch has failed or residue has set inside it. The switch harness needs replacing
Clicks only when one particular knob is touched or wiggledThat knob's switch
Clicks continuously and one burner will not lightPossibly a cracked igniter shorting as well
Do not leave a stove clicking for hours. It wears out the spark generator and the igniter tips. Leave it switched off at the socket and light with a match until it is dry or repaired.
On stoves with flame failure devices, you have to hold the knob in for a few seconds after the burner lights. That gives the thermocouple time to heat up and hold the gas valve open. If the flame dies when you release, the device is not holding.
1
Hold the knob fully pressed for ten to fifteen seconds after lightingThen release slowly. This is normal operation, and many no-light complaints are simply a knob released too soon.
2
Check the flame is touching the thermocoupleThe probe should be in the flame. A misplaced cap or blocked ports on that side leave it cold.
3
Clean the thermocouple tip gentlyBurner cold, with a dry cloth. Soot and residue insulate it.
4
Check for a draughtA fan or an open window can blow the flame off the probe.
Still goes outLikely cause
However long the knob is heldThermocouple worn out, or the magnet in the gas valve has failed
Holds some days and not othersLoose thermocouple connection at the valve
Only on the lowest settingSimmer flame too small to keep the probe hot. Needs adjusting
On every burner at onceLow gas pressure
Thermocouples are a routine replacement for a technician. Never defeat one. It is what stops gas flowing from a burner that has blown out.

A gas oven lights in the same way, with its burner hidden under the oven floor and usually a longer hold time.

When lighting a gas oven, keep the door open until the burner is lit. If it does not light within a few seconds, turn off, leave the door open for a minute and try again.
If the gas side is sound and only the ignition has failed, a hob burner can be lit by hand until it is repaired. Do it in this order.
1
Light the match or a long-reach lighter first
2
Hold the flame at the edge of the burner, by the ports
3
Then turn the knob to a low settingThe burner should catch at once.
4
On stoves with flame failure devices, keep the knob held in for ten seconds
5
If it does not light within three seconds, turn off and wait a minute
Flame first, gas second. Never the other way round.
Keep your face and sleeves back.
Do not light an oven by hand unless the manual describes how.
If a burner will not light with a match either, the problem is gas, not ignition. Go back to check 1.
This is a stopgap. A stove whose igniters have failed should be repaired.
StoveIgnitionCommonest reasons it will not light
Built-in gas hobMains spark, from the knobCap misplaced, wet after cleaning, igniter dirty, switch harness
Gas-on-glass hobMains sparkAs above. Spills run straight to the burner bases
Freestanding gas cookerMains or battery spark, sometimes a separate buttonBattery flat, plug out, cap misplaced, regulator
Range cookerMains spark, many burners on one generatorOne wet switch makes every burner click. Wok burner parts mixed up
Table-top two or three-burner stovePiezo in the knob, or batteryPiezo worn out, burner ports clogged, cylinder or regulator
Commercial rangeStanding pilot or electronicPilot blocked or out, flame sensor, interlock with the extraction fan
On a table-top stove with piezo ignition, each knob makes its own spark by a spring-loaded hammer. A knob that has lost its snap has a worn piezo. The burner will still light with a match.
Do not keep clicking with the gas on. Two or three short tries, then stop and wait.
Do not use a lighter to find out whether gas is coming.
Do not poke the jet with a pin.
Do not bend or twist the igniter.
Do not pour water over the hob to clean it.
Do not wedge a knob in to keep a burner alight.
Do not use a burner that burns yellow or lifts off its ports.
Do not dismantle valves, the hob top or the gas connection.
Do not ignore a smell of gas because the stove seems to be working.
You smell gas and cannot find an obvious cause such as an unlit burner.
One burner gets no gas with the others working.
There is no spark at one burner, or at any burner with the power proven.
The clicking continues after a full day's drying.
A flame will not hold however long the knob is pressed.
The flame is yellow, sooty, lifting or uneven after cleaning.
An igniter's ceramic is cracked.
The oven or grill will not light.
A knob is stiff, loose or will not turn off cleanly.
The hose is cracked, stiff or past its date, or the regulator is hissing.

Why is my gas stove clicking but not lighting?
+
The spark is not meeting gas. The burner cap is misplaced, the burner is wet or dirty, the ports by the igniter are blocked, or there is no gas because the cylinder is empty or a valve is closed.
Why is my gas stove igniter not clicking?
+
The ignition has no power. Check the plug, the socket and, on battery stoves, the battery. If power is present, the spark generator or switch has failed.
Why won't my gas stove stop clicking?
+
Water or grease has got into a switch under a knob. Switch off at the socket and let it dry for a day. If it continues, the switch harness needs replacing.
Why does my gas burner go out when I release the knob?
+
The thermocouple has not heated enough to hold the valve open. Hold the knob for ten to fifteen seconds. If it still goes out, the thermocouple needs replacing.
Can I light my gas stove with a match?
+
Yes, on the hob. Light the match first, hold it at the burner, then turn on the gas at a low setting.
Why will only one burner not light?
+
The fault is local: its cap or ring is misplaced, it is wet or blocked, or its igniter or jet is at fault.
Why will none of my burners light?
+
A shared fault: no gas, or no power to the ignition. Check the cylinder, the regulator and the valves, then the plug or battery.
How do I clean a gas stove igniter?
+
With the power off and the burner cold, brush the metal tip gently with a dry toothbrush. Do not bend it or soak it.
Is it dangerous if the stove clicks and does not light?
+
It can be, because gas is being released. Try for a few seconds only, then turn off and wait. If you smell gas, ventilate and close the supply.
Why does my burner light with a pop?
+
Gas is building up before it catches, because the ports near the igniter are blocked or the spark is weak. Clean the burner and do not keep trying.
Where is the battery on a gas cooker?
+
On battery-ignition cookers, usually in a holder under the front edge, behind the lower panel or in the storage drawer. Check the manual.
