A gas stove won’t light for one of two reasons: no spark, or no gas reaching it. A gas burner clicks but no flame means the spark is fine and the port is blocked, which costs nothing and is done well inside an hour. A technician measures a round igniter at about 2.5 to 3.0 amps.
Two reasons, and the sound tells you which
A gas stove won’t light for one of two reasons: no spark, or no gas reaching it. The sound tells you which. The appliance repair guide covers the other machines, including a fridge that stops cooling.
If you smell gas, stop and leave
This comes before every fix on this page, and it is not a formality.
Leave, then call from outside
Leave the building without operating any switch, including lights and extractor fans, and call your gas utility or 911 from outside. Do not go back in to open windows.
Safety, then diagnosis
Four steps in the right order
01
Smell gas? Leave first
Do not operate any switch or keep clicking the igniter. Leave and call the utility or 911 from outside.
02
Listen: clicking or silent?
Clicking means spark without gas. 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 it started after cleaning, several hours of drying is the fix.

Silence is the opposite: no spark, so the igniter, the module, or no power.
Most pages list every cause together. Splitting them removes half the list, which is why a gas stove won’t light diagnosis starts with sound.
The blocked port: the most common cause
Beside each igniter is a small gas port, exactly sized and placed to collect grease and boil-over.
Lift the grate and cap off, find the port facing the igniter, and clear it with a pin. Never a toothpick: a snapped tip inside a gas port is worse than the fault.
Why cleaning the stove breaks the ignition
The most searched version is a stove that worked yesterday and stopped after a clean.
Water in the ceramic base grounds the spark; water under the cap blocks the gas path. Neither is damage.
Drying is the whole repair
Dry everything and give it several hours. 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.
People skip this because the cap looks fine from above. Lift it and check.
One burner or all of them?
This is the question that decides who you should be calling.
One burner misbehaving points at its cap, port or electrode. All of them at once points at the spark module or the gas supply.
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, especially after a clean or a boil-over.
Why a weak oven igniter is the usual smell
If the smell comes from the oven, AppliancePartsPros, whose technicians work through this on camera, name the oven igniter as the most common source.
The igniter does two jobs: it glows to light the gas, and the current it draws holds the safety valve open. As it weakens it can crack that valve without getting hot enough to ignite, which is delayed ignition.
The amp test
Their technicians measure with a clamp meter: round igniters draw about 2.5 to 3.0 amps, square ones 3.3 to 3.6. Below 3.0 on a square or 2.2 on a round, the part gets replaced.
Where the igniter checks out, suspicion runs to cracked burner tubes, leaking manifold valves and the regulator. None is homeowner territory.
Burner cap seating and port blockage
The igniter electrode
Aluminum foil is not a harmless shortcut
Lining an oven or wrapping grates in foil is common advice and a bad idea.
Why foil backfires
AppliancePartsPros set out both. Under drip pans, foil traps moisture and rusts them out. On a cooktop it blocks the air passages the burners need, and incomplete combustion makes carbon monoxide.
The same source cites kitchen-fire statistics we could not trace to an originating authority, so we do not repeat them.
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.

These are not reviews of this site, and no names or ratings have been invented.
“LPT: If your gas stove fails to light despite the igniter...”
SourceThread title, the the most-read thread on this problem. The advice centers on the clogged gas port beside the igniter.
“How to fix stove burners that will not light after cleaning?”
SourceThread title from a public homeowner discussion forum. The answer is moisture rather than damage, and time rather than parts.
“Gas range clicks but does not ignite”
SourceThread title, diy.stackexchange.com. The replies separate a spark problem from a gas delivery problem immediately.
1 / 3
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.

Straight answers
Frequently asked questions
Short, plain answers to the questions people ask us most about this page.
What does it mean when a gas burner clicks but no flame appears?
The spark works and the gas is not arriving: a port blocked with grease, or a cap sitting proud of its seat. Both are free to fix.
Is it safe to keep clicking the igniter?
Only briefly, and never if you can smell gas: clicking with gas flowing builds an unburnt charge. Turn the knob off and check the port.
Why is my gas stove getting gas but not lighting?
The gas is not reaching the spark: a clogged port, or a cap sitting proud. Clear the port and reseat the cap flat.
What is the most common reason a gas stove won’t ignite?
A blocked burner port, then a misaligned cap, then moisture after cleaning.
My stove stopped working right after I cleaned it. Why?
Moisture. Water in the ceramic base grounds the spark; water under the cap blocks the gas. Dry it and wait.
Why does the igniter keep clicking after the burner lights?
Usually moisture bridging the spark gap, or a cracked ceramic igniter. Dry the area and let it sit; clicking that continues when dry means replacement.
I smell gas and the burner will not light. What do I do?
Leave immediately without operating any switch and call your gas utility or 911 from outside. Do not go back in until you are told it is safe.
Do I need a gas fitter or an appliance technician?
An appliance technician handles igniters and burner assemblies; a gas fitter or your utility handles supply, regulators and valves.
Blocked ports are the most common cause and clear with a pin and a brush. Everything below that row needs a technician.
