Clicks repeatedly but never lights
You hear the normal ticking sound and may smell a little gas, but the burner does not catch.
Start here: Start with burner cap alignment, blocked burner ports, and a wet or dirty igniter area.
Cooktop ignition problem
Gas Cooktop Burner Won’t Ignite
Direct answer: Most gas cooktop burners that will not ignite have a simple top-side issue first: the burner cap is out of position, the burner ports are clogged, or the igniter area is wet or dirty. If you hear clicking but do not get flame, start there before assuming a bad part.
Most likely: The most likely cause is a misaligned burner cap or debris around the burner head and igniter that keeps gas from catching at the spark.
First separate the symptom: does the burner click with no flame, light with a match but not on its own, or stay completely silent? That tells you whether you are dealing with a burner-top problem, an ignition problem, or a gas supply issue. Reality check: on gas cooktops, the fix is often right under the grate. Common wrong move: scrubbing the igniter hard or poking burner ports with something that enlarges them.
Don’t start with: Do not start by buying a cooktop igniter or switch because one dead burner is often a cleaning or alignment problem, not a failed part.

What the burner is doing tells you where to start
Lights with a match but not from the igniter
Gas is reaching the burner, but the built-in spark is not lighting it.
Start here: Look closely for a weak, off-target, or missing spark at that burner and inspect the cooktop igniter electrode.
One burner is dead but the others work
The problem stays at one spot while the rest of the cooktop behaves normally.
Start here: Focus on that burner’s cap, burner head, and cooktop igniter electrode before anything else.
No click and no ignition
Turning the knob gives you no ticking sound and no flame.
Start here: Check for power loss to the cooktop first, then consider a cooktop ignition switch or spark module problem if multiple burners are affected.
Most likely causes
1. Burner cap is off-center or seated wrong
A gas burner needs the cap and head lined up so gas flows evenly to the spark point. Even a slight tilt can keep it from catching.
Quick check: Lift the grate, let the burner cool, and make sure the cap sits flat without rocking.
2. Burner ports or burner head are clogged with food residue
Grease boilovers and crumbs block the small gas openings, so the spark clicks but the gas never reaches the flame edge cleanly.
Quick check: Look for blocked slots or holes around the burner head, especially near the igniter side.
3. Cooktop igniter electrode is wet, dirty, cracked, or sparking to the wrong spot
If the spark is weak, hidden, or jumping to metal instead of the burner, the gas will not light reliably.
Quick check: In a dim room, turn the burner briefly and watch for a strong blue-white spark at the electrode tip.
4. Cooktop ignition switch or spark module is failing
If there is no spark, weak spark on one burner, or erratic clicking across several burners, the ignition circuit may be the problem.
Quick check: See whether other burners spark normally and whether the bad burner ever clicks at all.
Step-by-step fix
Step 1: Make sure this is not a simple burner-top issue
Most single-burner ignition complaints come from a cap that shifted during cleaning or a burner top that is not sitting together correctly.
- Turn the burner knob off and let the cooktop cool fully.
- Remove the grate and lift off the burner cap.
- Set the burner cap back in place so it sits flat and centered with no wobble.
- If the burner head is removable on your cooktop, make sure it is seated correctly on its base and not cocked to one side.
- Try ignition again with the grate back in place.
Next move: You had a cap or burner-head alignment problem. No parts needed. Move on to cleaning the burner ports and igniter area.
What to conclude: When the cap is out of position, gas misses the spark path and the burner will click without lighting.
Stop if:
- You smell strong gas that does not clear quickly after turning the knob off.
- The burner parts are stuck and would need prying or force to remove.
- The cooktop surface is cracked or damaged around the burner.
Step 2: Clean the burner ports and dry the igniter area
Food residue and moisture are the next most common reasons a burner clicks but will not light, especially after a spill or recent cleaning.
- Turn the burner off and confirm all surfaces are cool.
- Remove the grate and burner cap again.
- Wipe the burner cap, burner head, and area around the cooktop igniter electrode with a damp cloth and a little mild soap if greasy.
- Dry everything thoroughly with a clean towel.
- Use a wooden toothpick or soft nonmetal pick to clear visible debris from the burner ports without enlarging them.
- Do not scrape the igniter tip with heavy force and do not flood the area with cleaner or water.
Next move: The burner was blocked or damp. Keep using it and watch for repeat boilover buildup. Check whether the burner has gas flow and whether the spark is actually reaching the gas.
What to conclude: A clean, dry burner should light quickly if gas flow and spark are both present.
Step 3: Separate gas-flow problems from spark problems
If the burner lights with a match, gas is present and the ignition side is the issue. If it does not light even with a match, the problem is farther upstream at that burner.
- With ventilation on and your face back, turn the burner briefly and listen for gas flow.
- If you are comfortable doing so, use a long match or long lighter to test whether the burner lights manually while the knob is in the light position.
- If it lights manually but not with the built-in spark, focus on the cooktop igniter electrode or ignition circuit.
- If it does not light manually and other burners do work, suspect a blocked burner head or burner base path at that burner.
- If no burners have gas, check that the appliance gas supply is on, but do not work on house gas piping.
Next move: If manual lighting works, you have narrowed it to the ignition side rather than the gas side. If the burner still will not light manually, stop at burner-top cleaning and call for service if the gas path inside the cooktop needs deeper work.
Step 4: Watch the spark closely and inspect the burner-specific ignition parts
Once you know gas is present, the next question is whether the spark is strong and landing where it should.
- Darken the room slightly and turn the problem burner on for a brief test.
- Look for a sharp spark at the cooktop igniter electrode tip aimed toward the burner edge.
- If the spark is weak, intermittent, or jumping to the cooktop frame, inspect the electrode for cracks, carbon tracking, or a bent tip.
- Compare the bad burner to a working burner if the layout is similar.
- If only one burner fails and the electrode is visibly damaged, that is the strongest part-failure clue on this page.
Next move: If you spot a damaged or misfiring electrode, replacing the cooktop igniter electrode is the most likely repair. If the electrode looks normal but there is still no reliable spark, the fault may be in the cooktop ignition switch or spark module.
Step 5: Decide whether this is a burner part repair or a service call
By now you should know whether the problem stayed at the burner top, the burner-specific igniter, or the shared ignition controls.
- If the burner now lights normally, reassemble everything and test ignition several times from cold.
- If one burner still has a weak or missing spark and the cooktop igniter electrode is cracked or clearly misfiring, replace that cooktop igniter electrode.
- If the burner cap or burner head is warped, damaged, or badly corroded and cleaning did not help, replace the affected cooktop burner cap or cooktop burner head as needed.
- If there is no clicking on one burner when the knob is turned, or clicking is erratic across several burners, schedule repair for a cooktop ignition switch or cooktop spark module.
- If gas flow to one burner seems restricted inside the cooktop body, stop DIY and have it serviced rather than opening gas components further.
A good result: You have a solid next action instead of guessing at parts.
If not: If the symptoms still do not line up cleanly, stop before buying parts and get a technician to test the ignition circuit safely.
What to conclude: Single-burner visible damage supports a burner-specific part. Multi-burner or no-click issues usually point to shared ignition components.

FAQ
Why does my gas cooktop burner click but not light?
Usually the burner cap is out of place, the burner ports are clogged, or the igniter area is wet or dirty. If you hear clicking, the cooktop is at least trying to spark, so start with the burner top before replacing parts.
If the burner lights with a match, what does that tell me?
That usually means gas is reaching the burner and the problem is on the ignition side. The most likely causes are a dirty, cracked, or misfiring cooktop igniter electrode, or less often an ignition switch issue.
Can moisture keep a gas burner from igniting?
Yes. After cleaning or a boilover, moisture around the igniter or burner head can short the spark or keep gas from catching cleanly. Drying the burner parts thoroughly often fixes it.
Why does only one burner fail when the others work?
That points first to a problem local to that burner: cap alignment, clogged ports, a damaged burner head, or a bad cooktop igniter electrode. Shared ignition parts become more likely when several burners act up together.
Should I replace the spark module if one burner will not ignite?
Not first. One dead burner is more often a burner-top issue or a single bad electrode. A cooktop spark module is more suspect when several burners have weak or erratic spark behavior.
Is it safe to keep clicking the burner until it lights?
Not for long. A few clicks is normal, but repeated attempts can let gas build up. If it does not light promptly, turn it off, let the gas clear, and inspect the burner top before trying again.
