Stove Burner Won’t Light? Here’s What to Check
Click. Click. Click. Click. And no flame.
It is one of the most irritating sounds in a kitchen, and here’s the good news: most of the time, this is not a broken stove. It’s a dirty one. The most common cause of a gas burner that won’t light is food debris or moisture in the burner head, and the fix is free and takes about fifteen minutes.
People replace whole ranges over what was a wet burner cap. Let’s not do that.
Gas safety, first and non-negotiable. If you smell gas when everything is switched off, this is not a troubleshooting problem. Do not flip switches, do not light anything, do not use your phone indoors. Turn off the gas at the shutoff valve if you can reach it safely, open windows, get everyone out of the house, and call your gas utility or 911 from outside. A brief whiff as a burner ignites is normal. A persistent smell, or any smell with the appliance off, is not. Gas line work belongs to a licensed professional, always.
Gas burners: work through these in order
1. Is the burner cap on straight?
Absurdly simple, and it’s the answer more often than anyone admits. The burner cap has to sit flat and correctly seated on the burner head. Knock it while cleaning, or reassemble it slightly off, and the burner won’t light properly, or will light unevenly.
Lift it off and reseat it. It should sit flush with no wobble.
2. Is anything wet?
If this started right after you cleaned the stove or after a pot boiled over, it’s moisture. Water in or around the igniter stops it sparking properly.
The fix: take the burner cap and head off, dry everything thoroughly, and leave it to air out for an hour or two. A hair dryer on a low setting speeds this up. Then reassemble. This resolves an enormous share of "my burner suddenly stopped working" calls.
3. Are the burner ports clogged?
The burner head has a ring of small holes (ports) that the gas comes out of. Food, grease, and boiled-over sauce block them. Symptoms: no flame, a weak flame, or a flame on only part of the ring.
The fix:
- Turn the burner off and let everything cool completely.
- Lift off the grate, cap, and burner head, they usually come off by hand.
- Wash the cap and head in warm soapy water. Scrub the crust.
- Clear each port with a straightened paperclip, a pin, or a stiff brush. Never use a toothpick, it can snap off inside and block the port permanently.
- Dry everything completely. This step is not optional.
- Reassemble, making sure the cap is seated properly.
Do this every month or two and you will essentially never have this problem.
4. Is the igniter dirty or failing?
The igniter is the small ceramic-and-metal nub next to the burner that makes the clicking. If it’s coated in grease or food, it can’t spark properly.
Clean it gently with a toothbrush and a little rubbing alcohol (with the stove off and cool). Be careful, it’s ceramic and it’s brittle.
How to read the clicking:
- Clicking, but no spark visible at the igniter → the igniter or the spark module has failed.
- Sparking, but no flame → gas isn’t reaching the burner. Clogged ports, or a gas supply issue.
- All burners clicking constantly, even when off → usually moisture, or a stuck/failing switch. Very often it clears once everything dries out.
- Only one burner is dead, the rest are fine → almost certainly that burner’s cap, ports, or igniter. Good news, this is the easy case.
- No burner works at all → check the gas supply first. Is the shutoff valve open? Is the gas on elsewhere in the house?
Electric coil burners
Electrical safety first: unplug the range, or switch off its breaker, before you pull coils or touch a socket. An electric range runs on 240V, and that is not a circuit to be casual around. Everything below is done with the power off.
Different machine, much simpler diagnosis.
- Is the coil seated properly in its socket? They work loose. Pull it out and push it firmly back in.
- Swap the coil with a working one of the same size. If the problem follows the coil, the coil is dead ($20–$50). If the problem stays with the socket, the socket or its wiring is the issue.
- Check for burn marks in the socket, that’s a bad connection and it needs attention.
This swap test is the single most useful thing you can do on a coil range, and it costs nothing.
Electric smooth-top burners
Less DIY-friendly, because the elements live under the glass.
- Does the element heat at all? If nothing happens, it’s likely the element or the switch.
- Does it heat only on high? That’s usually the infinite switch (the control), not the element.
- Cracked glass? Stop using that zone immediately. The elements underneath are live, and moisture reaching them is a shock hazard. This is a replace-or-repair decision, not a wait-and-see one.
These repairs generally mean calling someone.
What it costs
| Cause | Cost | Verdict |
|---|---|---|
| Burner cap misaligned | $0 | Reseat it |
| Moisture after cleaning / boil-over | $0 | Dry it out completely |
| Clogged burner ports | $0 | Clean them. The most common cause |
| Dirty igniter | $0 | Clean gently |
| Failed igniter | $70–$200 fitted | Repair |
| Spark module | $100–$250 | Repair |
| Electric coil element | $20–$50 | Repair. Easy |
| Coil socket / receptacle | $60–$150 | Repair |
| Smooth-top element | $150–$350 | Repair if under ~10 years |
| Infinite switch | $100–$250 | Repair |
| Cracked glass cooktop | $250–$500 | Usually replace the range |
| Gas leak inside the range | Varies | Replace on an older unit |
Notice how much of that column is $0. That’s the point of this article.
When to stop and call someone
- You smell gas. Stop. Follow the safety steps above. This is not a DIY situation.
- The knob doesn’t shut the burner off reliably. A gas burner you can’t turn off is a safety issue, not an inconvenience.
- Multiple burners have failed at once, which points at the spark module or wiring.
- The glass cooktop is cracked.
- You’ve cleaned everything thoroughly, dried it, and it still won’t light.
When to replace the range instead
A range lasts 13–15 years, and gas ones often longer because they’re mechanically simpler. Nearly every fault on this page is worth repairing, the parts are cheap and the labor is straightforward.
Replace when: the glass cooktop is cracked (the glass alone often costs as much as a better range), the control board has failed on an older unit, there’s a gas leak inside the range body, or you’re looking at several failures at once.

Prevention
- Pull the burner caps and heads off and wash them monthly. They lift right out.
- Wipe spills once the surface cools, before they carbonize.
- Dry everything completely after cleaning. Most "suddenly broken" burners are just wet.
- Don’t spray cleaner directly at the igniter or the control panel. Spray the cloth, not the appliance, liquid wicks in behind and kills electronics.

Frequently asked questions
Why does my gas burner click but not light?
The igniter is sparking but the gas isn’t catching, and the usual reason is debris or moisture. Take off the burner cap and head, wash them, clear each gas port with a pin or paperclip (never a toothpick, it can snap off inside), dry everything completely, and reseat the cap flat. This resolves the large majority of cases.
Why did my burner stop working right after I cleaned the stove?
Moisture. Water around the igniter or in the burner head stops it sparking or the gas catching. Remove the cap and head, dry everything thoroughly, and let it air out for an hour or two, a hair dryer on low speeds it up. Then reassemble. This is an extremely common and completely free fix.
Why do all my stove burners keep clicking?
Usually moisture, often after a boil-over or a clean, and it typically stops once everything dries out completely. If it persists, a stuck or failing switch or spark module is the likely cause. Note that the clicking itself isn’t dangerous, but you should turn the burners off while you sort it out.
How much does it cost to fix a burner that won’t light?
Very often nothing, because it’s debris or moisture. If the igniter itself has failed, expect roughly $70 to $200 fitted. A spark module is $100 to $250. An electric coil element is only $20 to $50 and is one of the easiest repairs there is.
Can I use a toothpick to clean burner ports?
No. A toothpick can snap off inside a port and block it permanently, which turns a free fix into a repair. Use a straightened paperclip, a pin, or a stiff brush instead, and make sure everything is bone dry before you reassemble.
When should I replace my stove instead of repairing a burner?
Most burner faults are worth repairing, the parts are cheap. Replace the range if the glass cooktop is cracked (the replacement glass often costs as much as a better range, and it’s a shock hazard), if the control board has failed on an older unit, if there’s a gas leak inside the range body, or if several things have failed at once.
