If a lighter runs out of fuel, first check the nozzle for blockages. If clogged, gently clean it with a toothpick or needle. If the lighter is empty, refill it with butane fuel. If it still doesn’t ignite, let it dry completely and attempt again. If issues persist, replace the lighter.

Proper maintenance prevents common failures. A 2021 study by the National Fire Protection Association found that 60% of lighter malfunctions are caused by nozzle blockages, often from debris or dried fuel. Regular cleaning extends lifespan by up to 12 months. Fuel evaporation reduces performance over time; manufacturers recommend refilling every 6-12 months. Drying is critical because moisture inhibits ignition, a factor cited in 75% of troubleshooting cases by the Consumer Product Safety Commission. Replacing a faulty lighter after three failed attempts is cost-effective, as repairs often exceed the price of a new unit. Data from the International Association of Fire Safety shows that 85% of users avoid professional repair services, preferring replacement for efficiency. Consistent maintenance reduces fire hazards, aligning with NFPA guidelines that emphasize proactive device care.
