Clicks normally but never lights
You hear the rapid clicking and may smell a little gas, but the flame never catches.
Start here: Look for a crooked burner cap, blocked burner ports, or a dirty/wet igniter area.
Direct answer: If one burner will not light but the others do, the usual cause is a misseated burner cap, clogged burner ports, or a wet/dirty burner head blocking gas from reaching the spark. If you hear clicking but never get flame, stay with the burner parts first. If there is no spark at all, the igniter path is more likely.
Most likely: Start with the burner cap and burner head. On gas cooktops, a cap sitting crooked by even a little can keep the flame from catching where the spark lands.
First separate the symptom: one burner dead, several burners dead, or no spark anywhere. That keeps you from chasing the wrong fix. Reality check: a burner that worked yesterday can quit today just from a boilover or a cap put back slightly off-center after cleaning. Common wrong move: scrubbing the igniter hard or poking burner holes with something that enlarges them.
Don’t start with: Do not start by buying a spark module or taking apart gas tubing. Most no-light complaints are at the burner top where you can see the problem.

Turning that knob does nothing while other burners still spark and light.
Start here: Check for a stuck or damaged burner knob stem, then inspect the burner igniter at that position.
Gas is reaching the burner, but the built-in spark is not lighting it.
Start here: Focus on the burner igniter tip, burner grounding through the cap and head, and debris around the spark path.
More than one surface burner is dead, weak to spark, or completely silent.
Start here: Check for power loss to the range first, then stop DIY if the ignition system appears dead across the cooktop.
The spark has to land in the right spot relative to the gas flow. If the cap is cocked or the head is not seated, the burner may click all day and never catch.
Quick check: With the burner off and cool, lift the cap and set it back so it sits flat with no rocking.
Food residue blocks the gas path around the burner ring, so gas does not reach the spark evenly.
Quick check: Look for plugged holes, sticky residue, or a section of the burner ring that looks crusted over.
After cleaning or a spill, the spark can short to the wrong spot or weaken enough that it will not jump where it should.
Quick check: If the problem started right after cleaning or a boilover, let the burner dry fully and wipe the igniter area clean.
If gas is present and the burner lights with a match but that burner has weak spark or no spark, the igniter at that burner is a strong suspect.
Quick check: Watch in a dim room for a strong blue-white spark at the igniter tip while turning the knob to light.
One dead burner usually points to burner-top parts. Several dead burners or no spark anywhere points to power or a larger ignition fault, which changes the repair path and the risk.
Next move: If the other burners spark and light normally, stay focused on the bad burner itself. If none of the burners spark, or several burners are acting up the same way, stop after basic power checks and arrange service for the ignition system.
What to conclude: A single-burner failure is usually local to that burner cap, burner head, or igniter. A cooktop-wide failure is less likely to be a simple top-side cleaning issue.
This is the most common fix and costs nothing. A cap that is just slightly off-center can keep the flame from catching even when spark is present.
Next move: If the burner lights right away now, the cap or head was out of position. Keep using it, but make sure it goes back the same way after cleaning. If it still clicks without lighting, move on to cleaning the gas ports and igniter area.
What to conclude: Good spark with bad cap alignment is a very common no-light complaint, especially after wiping the cooktop or removing caps for cleaning.
Grease, sauce, and cleaning moisture are the next most common reasons a gas burner will not light. You want the gas path open and the spark path dry.
Next move: If the burner lights normally now, the issue was blockage or moisture. That is a finished repair unless the problem keeps returning. If you still have gas but no ignition, check whether the burner lights with a match to separate gas flow from spark failure.
This tells you whether the problem is ignition only or whether that burner is not getting usable gas flow at the top.
Next move: If it lights with a match, gas flow is present and the built-in ignition at that burner is the likely problem. If there is no flame even with a match, or gas flow seems weak and uneven, the burner head or top-side gas path may still be blocked or misassembled. If it is already clean and seated correctly, call for service.
By now you have narrowed it down. If the burner lights with a match but not from its own spark, the surface burner igniter is the strongest supported part call. If the burner top is damaged and will not seat correctly, the cap or head is the better fix. If several burners are dead, this is no longer a simple burner-top repair.
A good result: If the burner now lights within a few clicks and the flame ring is even, the repair is complete.
If not: If a new burner-top part does not fix a proven ignition problem, the fault is likely deeper in the range ignition circuit and is better handled by a tech.
What to conclude: This is where you stop replacing obvious burner-top parts and avoid chasing larger gas or electrical faults without proper testing.

Most of the time the burner cap is not seated right, the burner holes are clogged, or the igniter area is wet or dirty. If the burner lights with a match, gas is present and the spark side is the problem.
That usually means the problem is local to that burner, not the whole range. Start with the cap, burner head, and igniter at that spot before suspecting a larger ignition failure.
Yes, but only as a brief controlled test if you are comfortable around gas appliances. It helps confirm whether gas is reaching the burner. Stop immediately if gas odor gets strong or ignition is delayed.
Not first. Burner cap alignment, clogged ports, and moisture cause a lot of no-light complaints and are much more common. Replace the range surface burner igniter only after those checks and after manual lighting shows gas is present.
Usually because the cap went back slightly crooked or moisture got around the igniter and burner head. Dry everything thoroughly, reseat the parts carefully, and try again.
That points away from a single burner problem. Check that the range has power, then stop DIY if the whole ignition system stays dead. A cooktop-wide ignition fault is not a good guess-and-buy repair.
