Lighter won't light

A butane lighter that sparks but won't flame is usually low or empty fuel, while one that won't spark at all usually has a worn flint or dirty striker wheel; both are quick checks.

Symptoms

  • Wheel spins but no flame appears
  • No spark at all when the wheel is spun
  • Flame is very small or weak
  • Lighter worked fine yesterday, dead today

Likely causes

  • CommonEmpty or low butane fuelFuel naturally depletes with use, or leaks slowly through the valve over time.
  • CommonWorn-down flint (for flint-wheel lighters)The flint wears shorter with every spark until it stops reaching the wheel.
  • PossibleDirty or clogged striker wheel or jetPocket lint and dust can gum up the wheel or block the gas jet.
  • PossibleWet lighter after exposure to water or high humidityMoisture on the flint or striker prevents a good spark.
  • Less commonChild-safety lock engaged (on some lighters)Some lighters have a small switch that must be disengaged first.

What to do

  1. Check the fuel level if it's a see-through or refillable butane lighter; refill if low.
  2. For disposable lighters, shake gently and hold up to see if you can gauge remaining fuel by weight or sound.
  3. Dry the lighter thoroughly with a cloth if it's been wet, including the striker wheel and flint area.
  4. Brush the striker wheel with an old toothbrush to remove lint or dust buildup.
  5. For a flint lighter with weak sparks, the flint may be worn out; many refillable lighters let you replace the flint.
  6. If the lighter has an adjustment wheel or dial, check it isn't turned down to minimum flame.
  7. If it still won't light after refueling and cleaning, the internal igniter or valve may be faulty and the lighter should be replaced.

When to call a pro

No professional service exists for lighters; replace a disposable one or a badly worn refillable one.

Safety

Use caution

Refuel and use lighters away from open flame and in a well-ventilated area; never test near your face.
