Direct answer: If a range burner clicks but does not light, the usual causes are a misseated burner cap, clogged burner ports, moisture around the igniter, or no gas reaching that burner. Start with the burner head and cap before assuming the igniter itself is bad.
Most likely: On most gas ranges, this turns out to be a dirty or wet burner assembly, or a cap that is slightly off-center so the spark never catches the gas at the right spot.
Separate one-burner trouble from all-burner trouble right away. If only one burner clicks with no flame, stay at that burner and check cap fit, port blockage, and moisture first. If every burner clicks and none light, think gas supply or a broader range issue before you chase individual parts. Reality check: a burner can click strongly and still fail to light if the gas never reaches the spark. Common wrong move: scrubbing the igniter hard with something abrasive and cracking the ceramic.
Don’t start with: Do not start by buying a range spark igniter or taking apart gas tubing. A steady click means the spark side is often still working.
You hear rapid clicking at one burner, may smell a little gas, but that burner never catches while the others work normally.
Start here: Start with burner cap position, blocked burner ports, and moisture on that one burner.
The burner clicks for several seconds before finally lighting all at once.
Start here: Check for partially clogged burner ports or a cap that is not seated flat.
Every burner sparks, but no burner gets flame.
Start here: Check that the gas supply is on and that the range is actually getting gas.
The problem started right after wiping the cooktop, a spill, or a pot boiling over.
Start here: Let the burner dry fully, then clean and re-seat the cap and burner head.
The spark may be present, but the gas stream is not meeting it where it should. Even a small tilt can stop ignition.
Quick check: Lift the cool cap, set it back into its locating notch or tabs, and make sure it does not rock.
Gas cannot flow evenly across the burner, so the spark clicks without finding enough fuel at the ignition point.
Quick check: Look for blocked slots or holes near the igniter side of the burner head.
Water from cleaning or a spill can short the spark path or keep the flame from catching cleanly.
Quick check: If the problem started after cleaning, let the burner air-dry completely and try again later.
A clicking igniter with no flame on every burner usually points to supply, while one dead burner can point to a burner valve issue.
Quick check: Try another top burner and, if safe, check whether another gas appliance in the home is working.
This separates a simple burner-top problem from a gas supply problem before you waste time cleaning or replacing the wrong part.
Next move: If other burners light normally, stay focused on the one bad burner. The problem is usually local to that burner assembly. If no burners light, treat this as a gas supply or broader range problem, not a single igniter problem.
What to conclude: One-burner failure usually means cap alignment, clogged ports, moisture, or a burner-specific ignition or valve issue. All-burner failure points higher up the chain.
This is the most common fix, especially after cleaning, moving grates, or lifting the cap to wipe underneath.
Next move: If the burner lights right away now, the spark was fine and the cap or head was simply out of position. If it still clicks with no flame or lights very late, move on to cleaning the burner ports and drying the area.
What to conclude: A burner that starts working after re-seating had a spark-to-gas alignment problem, not necessarily a failed part.
Grease, boilover residue, and moisture are the next most common reasons a clicking burner will not catch.
Next move: If the burner now lights quickly and evenly, the issue was blockage or moisture. If you still get a healthy click but no flame on that one burner, the burner may not be getting gas correctly or the spark may be jumping in the wrong place.
A visible spark in the wrong spot, or gas that reaches the burner too weakly, tells you which part is more likely at fault.
Next move: If you see a clean spark at the right spot and smell a little gas but still get no ignition until after cleaning and re-seating, the burner head or cap may still be damaged or not passing gas evenly. If there is weak, erratic, or misdirected spark on the bad burner, or no gas smell at that burner while others work, you have a stronger case for a burner-specific part failure.
By now you should know whether this is still a simple burner-top issue, a likely igniter problem, or a gas-delivery problem that should not be guessed at.
A good result: If the burner lights within a click or two and burns evenly around the ring, the repair path was correct.
If not: If a new burner-top part does not change the symptom, the problem is likely deeper in the range ignition or gas valve system and is no longer a good guess-and-buy repair.
What to conclude: The safe homeowner fixes here are burner-top parts. Once the diagnosis points into internal gas control or wiring, professional service is the right next move.

Most often the burner cap is out of place, the burner ports are clogged, or the burner is still damp from cleaning. If every burner clicks but none light, check gas supply before blaming the igniters.
Yes. A range spark igniter can click but still be weak, cracked, or sparking to the wrong spot. That said, cap alignment and clogged ports are more common than a failed igniter on a single burner.
Moisture around the igniter and burner base is a very common cause. Let the burner dry fully, then re-seat the cap and try again.
Turn the knob off right away. A faint whiff during a brief test can happen, but a strong or lingering gas smell means stop, ventilate, and do not keep clicking the burner.
Stay focused on that burner. The usual suspects are that burner's cap, burner head, igniter, or burner-specific gas delivery. Start with the cap and ports before considering parts.
Not for this symptom. A clicking burner means the ignition system is at least trying to fire. On a one-burner problem, burner-top parts are far more likely than a broader control failure.
