Direct answer: If your LG stove burner keeps clicking, the usual cause is moisture, grease, or a burner cap that is slightly out of place around the surface burner igniter. If the clicking continues after the burner is dry and seated correctly, the next likely problem is a stuck range burner spark switch or a failing surface burner igniter.
Most likely: Start with the burner that was just used, boiled over, or cleaned. On these ranges, one wet or dirty burner area can keep the igniter system snapping even when the flame looks normal.
First figure out whether only one burner clicks or every burner clicks, and whether it stops when the burner lights. That split tells you a lot. Reality check: a simple boil-over is more common than a failed part here. Common wrong move: scrubbing the igniter tip hard or flooding the burner with cleaner, which can make the clicking worse.
Don’t start with: Do not start by ordering a control board. Continuous clicking is much more often a wet burner, dirty igniter area, or a bad burner switch at the knob stem.
Usually one burner keeps snapping while the others act normal. It may light late, light unevenly, or keep clicking after the flame is on.
Start here: Check that burner's cap position, ports, and igniter area for moisture, grease, or food crust.
You hear rapid clicking from more than one burner, often even though you only touched one knob.
Start here: Look for a wet or stuck range burner spark switch behind one knob, especially the burner that was just used or cleaned.
The cooktop was wiped down or sprayed, and now the igniters keep snapping longer than normal or with the knobs off.
Start here: Let the burner area dry fully, remove and dry the burner caps, and avoid more cleaner until the igniter area is dry.
The flame comes on, but the snapping sound keeps going instead of stopping right away.
Start here: Focus on burner cap alignment and flame contact at the igniter. If the flame looks normal and clicking still continues, move to the spark switch check.
This is the most common cause after wiping the cooktop, a boil-over, or heavy steam from cooking. The spark tracks where it should not and keeps firing.
Quick check: With the burner cool, remove the cap and let the area air-dry. Blot around the igniter and burner base, then try again later.
If the cap sits crooked, the flame may not ground and wrap correctly at the igniter, so the module keeps clicking even though gas is lighting.
Quick check: Lift the cap, clear crumbs, and set it back so it sits flat without rocking.
A dirty burner can light unevenly or away from the igniter, which causes repeated snapping and delayed ignition.
Quick check: Look for clogged flame ports, sticky residue, or charred food around the burner head and igniter tip.
If clicking continues with all knobs off, or all burners click together, one switch may be wet, sticky, or shorted at the valve stem.
Quick check: Turn each knob gently off and on one at a time. If one knob feels sticky or makes the clicking change, that switch path is the lead suspect.
You do not troubleshoot a single wet burner the same way you troubleshoot all burners clicking with the knobs off.
Next move: If you can tie the problem to one burner, stay focused there first. That is the most common and least expensive fix path. If the clicking seems random, continues with all knobs off, or involves several burners together, move quickly to the switch and safety checks.
What to conclude: One-burner clicking usually points to moisture, dirt, cap alignment, or that burner's igniter area. Whole-cooktop clicking points more toward a wet or stuck range burner spark switch.
This solves a large share of continuous clicking calls, especially after cleaning or a pot boiling over.
Next move: If the clicking stops or returns to a brief normal spark, the issue was moisture or cap alignment. If the burner still clicks constantly, lights late, or keeps clicking after ignition, clean the burner head and igniter area next.
What to conclude: A burner that improves after drying almost always had moisture or a slightly misaligned cap, not a failed major component.
Grease film and food crust can throw the flame pattern off just enough to keep the igniter snapping.
Next move: If the flame now lights evenly and the clicking stops right away, the problem was poor flame carry from dirt or grease. If the burner lights but keeps clicking, or if all burners still click with knobs off, check the knob and spark switch behavior next.
When all burners click together or clicking continues with the knobs off, one switch at a valve stem is often the culprit.
Next move: If the clicking stops after drying the knob area, you likely had moisture or residue at the spark switch stem. If one knob clearly affects the clicking and the problem keeps returning, plan on replacing that range burner spark switch. If no knob stands out but one burner still misbehaves, the surface burner igniter is more likely.
By this point you should have ruled out the easy fixes and narrowed it to the main likely component.
A good result: If the clicking is gone and each burner lights promptly, the repair path was correct.
If not: If the clicking remains after the obvious switch or igniter fix, the problem may be in the ignition harness or spark module, which is a better pro repair on a gas range.
What to conclude: Most homeowners can solve this with drying, cleaning, cap alignment, or a burner switch or igniter replacement. Persistent unexplained clicking needs a technician before it turns into a gas-lighting problem.

Most of the time the burner cap is slightly out of place, the burner ports are dirty, or moisture is still around the surface burner igniter. The flame lights, but it is not reaching the igniter the way it should, so the clicking keeps going.
On many gas ranges, one wet or stuck range burner spark switch can make the whole ignition system click together. If all burners click with the knobs off, look hard at the knob area for moisture or a sticky switch.
Often, yes. If the problem started after cleaning or a spill, drying the burner cap, burner head, and knob area can solve it. Give it time to air-dry fully before assuming a part has failed.
If the burner lights quickly and the clicking stops right away, that is normal. If it keeps clicking, lights late, or clicks with the knobs off, stop using it until you fix the cause. Continuous clicking can turn into a no-light or gas-odor problem.
If only one burner acts up, start with that burner's cap, ports, and surface burner igniter. If all burners click together or the clicking continues with all knobs off, the range burner spark switch is the stronger suspect.
