Gas stove won't light: what the clicking is telling you
A burner that clicks is generating spark and not receiving gas. A burner that is silent has a different problem entirely. That one distinction sorts almost every case.
A gas stove won't light for one of two reasons: the spark is not being generated, or the gas is not reaching it. The sound the burner makes tells you which within a second, and the most common cause of all costs nothing to fix.
If you smell gas, stop and leave
This comes before every fix on this page, and it is not a formality.
Leave the building without operating any switch, including light switches and extractor fans. Call your gas utility or 911 from outside. Do not go back in to open windows and do not keep clicking an igniter in a room that smells of gas.
Clicking an igniter is generating sparks
The reason this warning belongs above the troubleshooting is that the troubleshooting itself involves making sparks. If there is gas in the room, that is precisely the wrong thing to do. Smell first, diagnose second, and if there is any doubt, leave.
Safety, then diagnosis
Four steps in the right order
01
Smell gas? Leave first
Do not operate any switch, do not keep clicking the igniter, and do not investigate. Leave the building and call the gas utility or 911 from outside.
02
Listen: clicking or silent?
Clicking means the spark is being generated and the gas is not arriving. Silence means the igniter, the spark module or the power supply.
03
Lift the cap and clear the port
Remove the grate and burner cap, then clear the small gas port beside the igniter with a pin or a straightened paper clip. Never a toothpick.
04
Dry everything thoroughly
Moisture in the ceramic igniter base grounds the spark. If this started right after cleaning, drying it out for several hours is the fix.
Gas stove won't light: clicking or silent?
What does the clicking actually mean?
That the spark module is working and delivering a spark to the electrode. If a burner clicks and does not light, the electrical half of the system is fine and the gas is not arriving at the spark gap. That points at the port, the cap or the supply.
Silence is the opposite signal. No clicking means no spark, which points at the igniter itself, the spark module, or the fact that the stove has no power at all.
Most pages on this topic list every cause together. Splitting them first removes half the list, which is why a gas stove won't light diagnosis should start with the sound rather than with a parts catalogue.
The blocked port: the most common cause
Beside each igniter is a small gas port, and it is exactly the size and location to collect grease and boil-over.
Lift the grate and the burner cap off. Find the small hole or slot facing the igniter and clear it with a pin or a straightened paper clip. Never use a toothpick, because a snapped tip inside a gas port is a worse problem than the one you started with.
Why cleaning the stove breaks the ignition
The most searched version of this problem is a stove that worked yesterday and stopped after a thorough clean.
Water in the ceramic base of the igniter grounds the spark so it never jumps the gap. Water trapped under the burner cap blocks the gas path. Neither is damage and both look identical to failure.
Dry everything properly and give it several hours if it got genuinely wet. Patience is the entire repair.
The burner cap has to sit flat
Seated flat: a cap that rocks or sits proud misdirects the gas away from the spark.
Correct cap: caps for different burner sizes are frequently not interchangeable.
Clean underside: carbon on the underside changes how the cap seats.
Right way up: some caps have an orientation notch that is easy to miss.
This is the free fix people skip because the cap looks fine from above. Lift it, look at the seat, and put it back deliberately.
One burner or all of them?
This is the question that decides who you should be calling.
One burner misbehaving points at that burner: its cap, its port, its electrode. All burners failing at once points at the spark module or at the gas supply itself. If none of your gas appliances are working, including a water heater or furnace, that is a supply question for the utility rather than a stove question.
The igniter that clicks and will not stop
Continuous clicking after a burner has lit is a distinct and very common complaint.
Moisture bridging the spark gap is the usual cause, particularly after cleaning or a boil-over. Turn every knob to off, dry the area thoroughly and give it time. Clicking that persists once everything is genuinely dry usually means a cracked ceramic igniter, which is a replacement rather than a clean.
Where the licensed work line sits
Who handles which part of a gas stove?
You handle caps, ports and drying. An appliance technician handles igniters, electrodes, spark modules and burner assemblies. A licensed gas fitter or your utility handles supply lines, regulators and valves. Those boundaries are not negotiable.
Our page on gas appliances and carbon monoxide covers why the utility takes a suspected leak seriously and why calling them costs nothing.
If you smell gas, stop. Turn the burner off, ventilate, leave, and call the gas utility from outside. Do not test switches or use a phone indoors.

“LPT: If your gas stove fails to light despite the igniter...”
SourceThread title, the number one organic result for this query. The advice centres on the small gas port beside the igniter clogging with grease and food debris.
“How to fix stove burners that will not light after cleaning?”
SourceThread title from a community discussion on this SERP. The consistent answer is moisture rather than damage, and the fix is time rather than parts.
“Gas range clicks but does not ignite”
SourceThread title, diy.stackexchange.com. Useful because the replies separate a spark problem from a gas delivery problem in the first few comments.

The after-cleaning thread is the one worth reading twice, because the natural assumption is that something broke and the actual answer is that something is wet.
How the matching works, and what we do not do
Emergency Services 24H is a referral service. We do not employ appliance technicians or gas fitters, and we do not sell parts.
Your request routes by ZIP code to licensed, insured technicians covering your area, and they contact you directly. For a suspected gas leak, your utility comes first and we are not a substitute for that call.

Straight answers
Frequently asked questions
The questions homeowners actually search for on this problem, answered in plain language.
Because the gas is not reaching the spark. The small port beside the igniter clogs with grease and food debris, and a burner cap that sits proud of its seat sends gas away from the spark gap. Clear the port with a pin and reseat the cap flat.
What is the most common reason a gas stove won't ignite?
A blocked burner port, followed closely by a misaligned burner cap and moisture after cleaning. Genuine igniter failure is less common than the search results imply, which matters because the first three cost nothing to fix and the fourth is a part and a service call.
My stove stopped working right after I cleaned it. Why?
Moisture. Water in the ceramic igniter base grounds the spark, and water trapped under the burner cap blocks gas from reaching the spark gap. Dry everything thoroughly and give it several hours before deciding anything has failed.
Why does the igniter keep clicking after the burner lights?
Usually moisture bridging the spark gap, or a cracked ceramic igniter. Turn every knob to off, dry the area around the burner and let it sit. If the clicking continues once everything is dry, the igniter itself needs replacing.
I smell gas and the burner will not light. What do I do?
Leave the building immediately without operating any switches, and call your gas utility or 911 from outside. Do not keep clicking the igniter, do not open windows on your way past, and do not go back in until you have been told it is safe.
Do I need a gas fitter or an appliance technician?
An appliance technician handles igniters, spark modules and burner assemblies. A licensed gas fitter or your utility handles supply lines, regulators and valves. If none of your gas appliances are working, that is a supply question and it starts with the utility.
