Direct answer
For the LG LSGL6335 gas range, a wet/dirty or mis-seated cap, blocked ports and ignition/supply faults should be separated. First, turn controls off, cool, then clean/dry and seat approved burner parts.
What this covers
- LG LSGL6335 gas range (LSGL6335F)
- LG range/oven; gas, electric, induction, ProBake, InstaView and ThinQ equipment vary.
- The specific fault this record addresses: gas burner clicks but will not light
What it does not cover
- ×The same symptom on a different LG product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The burner cap or head is wet, greasy or misseated
What separates it Clicking or a glow-bar sound continues without a flame, often after the cooktop was recently cleaned or something spilled and dried around the burner.
How to confirm Turn the control off, let everything cool, then remove and thoroughly dry the burner cap and head, seating it exactly as the manual shows — misalignment by even a small amount can block the spark-to-port path.
- 2
The burner ports are blocked with food residue
What separates it Weak, orange, or uneven flame once lit, or ignition that only succeeds on some ports around the ring.
How to confirm Clean the ports with a fine wire or the manufacturer's specified tool, never widening them with anything metal.
- 3
The igniter module or spark electrode has failed on that specific burner
What separates it No clicking sound at all from that burner while adjacent burners click normally.
How to confirm Compare the same test across all burners — a single silent burner with others working normally isolates that burner's igniter, not the whole range.
- 4
The gas supply itself is restricted or the shutoff is only partly open
What separates it All burners struggle equally, or the range was recently serviced, moved, or had gas lines worked on.
How to confirm Confirm the manual shutoff valve is fully open before assuming any single-burner part has failed.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether clicking or a glow-bar sound is present at all, and whether it's isolated to one burner or affects all of them.
- Whether the cooktop was recently cleaned, or anything spilled around the affected burner.
- The flame color and evenness once lit, if it does eventually light.
Turn off, cool, then clean and dry the affected burner cap and head
ReversibleReseat exactly per the manual — misalignment is the most common cause of this exact symptom.
Compare spark/click behavior across all burners
ReversibleIsolates a single failed igniter from a supply-wide problem.
Clean visibly blocked ports with the specified tool
ReversibleNever widen ports with metal tools not intended for this.
Confirm stable, even ignition and flame on the repaired burner
ReversibleTest more than once to confirm it wasn't a one-time fluke.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- LSGL6335F. LG range/oven; gas, electric, induction, ProBake, InstaView and ThinQ equipment vary.
- Cooktop — GAS (igniter + flame)
- A GAS cooktop — burners click to ignite. A burner that clicks but will not light is usually a wet/misaligned cap or clogged ports; dry, clean and reseat it. No click means the igniter or power. The gas supply must be on.
- Oven — gas
- Gas oven with a glow-bar igniter. A gas oven that will not heat is usually a weakening oven igniter (glows but cannot open the gas valve) — a common wear part.
- Features
- ProBake convection and Air Fry on most builds, ThinQ Wi-Fi on smart builds.
- Symptom boundary
- This record covers LG LSGL6335 gas range when it gas burner clicks but will not light. A different symptom on the same hardware, or this symptom on a different LG product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !A strong gas odor or repeated clicking with no flame across multiple burners: turn off the gas supply, ventilate, and do not attempt further troubleshooting yourself — call for service or the gas utility.
Evidence ledger
Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. LG publishes this as "LG Range - Troubleshooting a Burner Not Igniting On My LG Range". Surface burner that clicks/sparks but does not light. What that article does not carry is the model boundary — it is written for a product line, and LSGL6335F is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
My LG LSGL6335 gas oven won't get hot.+
The most common cause is a weak oven igniter. The glow-bar igniter must heat enough to open the safety gas valve; as it ages it still glows but no longer draws enough current to open the valve, so the oven never lights. If the igniter glows dull orange and no flame follows within a minute or two, it likely needs replacing. Confirm the gas supply is on first; the cooktop burners lighting does not prove the oven igniter is good.
One burner clicks but won't light, and I just cleaned the stovetop.+
This is almost always a wet, greasy or misseated burner cap after cleaning. Turn it off, let it cool, dry the cap and head completely, and reseat it exactly as the manual shows — misalignment by even a small amount blocks the spark from reaching the gas port.
A burner doesn't even click, but the others do.+
That isolates the fault to that single burner's igniter or spark electrode rather than the whole range's ignition system or gas supply.
Does this answer apply to every LG model?+
No. It is scoped to LSGL6335F. LG range/oven; gas, electric, induction, ProBake, InstaView and ThinQ equipment vary.
What should I record before troubleshooting burner won't light or clicking?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing burner won't light, clicking. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Turn off gas and ventilate for strong odor or repeated clicking without flame.
