LG Ovens & Ranges Gas Burner Won't Light: How to Fix It Yourself

An LG gas burner that clicks but does not light is almost always caused by a clogged igniter port or a wet igniter. Spilled food or moisture from cleaning blocks the spark from reaching the gas. A quick cleaning fixes it in most cases.

⚡ Difficulty: Easy⏱ 10-20 minutes💰 Parts cost: $0–$15🔧 Tools: Toothbrush or small brush, Sewing needle or straight pin, Towels

⚠️ Safety First

  • If you smell gas and the burner will not light, turn off the gas and ventilate the room immediately.
  • Do not use a lighter to ignite a burner that is clicking but not lighting — fix the root cause.
  • Never spray cleaners directly onto the igniter.

Step-by-Step Repair

  1. 1

    Check if gas is reaching the burner

    Turn the burner knob and listen. You should hear the clicking of the igniter and smell a faint gas odor. If there is no gas smell, the gas supply may be off. Check the gas shutoff valve behind the range and make sure it is open.

  2. 2

    Remove the burner cap and grate

    Lift off the grate and the burner cap (the round disc on top of the burner base). The cap just sits on top and lifts straight off. Set them aside.

  3. 3

    Clean the igniter electrode

    Locate the small white ceramic igniter next to the burner. Use a dry toothbrush to gently clean around the igniter tip. Remove any food debris or grease. Use a sewing needle to clear the tiny port holes in the burner base where gas comes out.

  4. 4

    Dry everything thoroughly

    If the burner was recently cleaned or a spill occurred, moisture on the igniter prevents sparking. Wipe the igniter and burner base with a dry cloth. You can use a hair dryer on low to speed up drying. Make sure no water remains in the burner ports.

  5. 5

    Realign the burner cap and test

    Place the burner cap back on the base. It must sit flat and aligned properly — a tilted cap directs gas away from the igniter. Replace the grate, turn the knob, and the burner should light. If it clicks but still does not light, the igniter switch itself may need replacing.

If That Didn't Work

  • Faulty spark module (all burners not clicking)
  • Damaged igniter wire connection
  • Gas regulator issue (weak flame on all burners)

When to Call a Professional

If none of the burners will click or light, the spark module may be dead. If you smell gas but no burners light after cleaning, call a technician or gas company immediately for safety. Spark module replacement costs $80–$150.
