LG Ovens & Ranges Gas Range Burners Won't Ignite: How to Fix It Yourself
When LG gas range burners click but won't light, or won't click at all, the most common cause is food or grease clogging the igniter or burner ports. A thorough cleaning fixes this about 80% of the time. It's free and takes 15 minutes.

- If you smell gas when no burners are on, leave the house immediately and call your gas company. Do not flip light switches or use your phone inside.
- Never use matches or lighters as a permanent fix for a burner that won't spark — find and fix the real problem.
- Make sure all burner knobs are in the off position before cleaning.

Step-by-Step Repair
- Step 1 of 51
Make sure the burner parts are seated correctly
Remove the burner grate, burner cap, and burner head. These come apart easily — just lift them off. Check that nothing is misaligned. When people clean the stove and put these parts back on crooked, the burner won't light. Reposition them properly.

Clean the igniter
The igniter is a small white or gray ceramic nub near the burner. Use an old toothbrush to gently scrub food residue and grease off it. Be gentle — the ceramic is fragile. Wipe with a dry cloth. Even a thin film of grease on the igniter can prevent it from sparking.

Clear the burner ports
Look at the small holes around the burner head where the flame comes out. Use a sewing needle or straightened paperclip to poke out any clogged ports. Don't use a toothpick — it can break off inside. Brush away any loosened debris.

Dry everything thoroughly
If the burners got wet from cleaning or a boil-over, they won't ignite until dry. Wipe every component with a dry towel. You can speed up drying by turning on a working burner nearby (the heat helps), or use a hair dryer on a low setting. Wait until everything is completely dry before testing.

Test the igniter spark
Turn the burner knob to the Lite position. You should see a small blue spark at the igniter. If you see a spark but the gas doesn't light, the burner ports are still clogged. If there's no spark at all on any burner, the spark module may be faulty. If only one burner has no spark, the igniter wire for that burner may be loose or damaged.

If That Didn't Work
- A faulty spark module (the box that powers all the igniters) can stop all burners from sparking at once.
- A loose or damaged igniter wire connection can affect individual burners.
- The gas supply valve under the stove or at the wall may not be fully open.
When to Call a Professional
If you smell gas but the burner won't light even with a match, turn off the gas and call a professional. If the spark module has failed, replacement costs $50–$100 with labor. If you're not comfortable working around gas connections, always call a pro.
