Direct answer
For the LG LSGL6335 gas range, new-appliance curing, food residue, foil, grease and electrical/gas faults require different action. First, turn off heat and identify food/grease smoke versus electrical or gas odor.
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: smokes or smells during use
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
A new range is curing its factory protective coating
What separates it A distinct smell, sometimes with light smoke, occurring only in the first few uses of a brand-new range.
How to confirm Run a short, ventilated empty bake cycle per the manufacturer's break-in guidance — this typically resolves within the first few uses.
- 2
Food residue, grease or foil is burning off
What separates it A cooking-related smell tracing to visible spills, grease buildup, or foil accidentally left in contact with a heating surface.
How to confirm Turn off heat, let cool, and inspect for and remove the specific residue or foil.
- 3
An electrical component is overheating
What separates it A sharp, acrid smell distinct from food or new-appliance odor, possibly present even without active cooking.
How to confirm This calls for stopping use and having it inspected rather than continued troubleshooting by smell alone.
- 4
A gas leak or incomplete combustion
What separates it A gas-specific odor, or smoke and a smell that appears specifically when gas burners or the gas oven are in use.
How to confirm Any suspicion of a gas smell overrides all other troubleshooting — treat it as an emergency, not a diagnostic puzzle.
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.
- The precise character of the smell — new-appliance curing, food/grease, sharp electrical, or gas — since each has a different urgency.
- Whether the smell/smoke is present only during active cooking, or also when the appliance is off.
- Whether the range is new, or this is a sudden change on a range that's been in use for a while.
Turn off heat immediately and identify the smell's character
ReversibleDistinguish food/grease from electrical or gas before any further action.
Inspect the cooled oven and cooktop for spills, foil or grease residue
ReversibleClean by the approved method for visible causes.
For a new range, run the manufacturer's documented break-in cycle with ventilation
ReversibleResolves curing-coating odor, typically within the first few uses.
Do not resume use for an electrical or gas odor until the cause is professionally identified
ReversibleThis is not a self-diagnosable category.
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 smokes or smells during use. 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.
- !For fire: turn off heat, keep the door closed if it's contained inside the oven, and call emergency services immediately.
- !Any gas odor: leave the area, do not operate any switch, and call the gas utility or emergency services from outside.
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 New Range - Strong Odor or Smoke". Smoke and strong smells during range use, including the break-in burn-off. 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.
My brand-new range smells and smokes a little when I first use it.+
This is normal for many new ranges — it's the factory protective coating curing off, and it typically clears within the first few uses. Run it ventilated per the manufacturer's break-in guidance rather than assuming a fault.
There's a sharp smell that isn't like food, even when nothing's cooking.+
That character of smell — not food-related, present even without active cooking — is exactly the case to stop using the range and have it inspected rather than continuing to troubleshoot by smell.
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 smoke or odor?+
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 smoke, odor. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
For fire, turn off heat, keep the door closed and call emergency services; leave for strong gas odor.
