When a lighter stops working, first check if it has fuel. If empty, refill it with lighter fluid. Next, clean the wick and jet by disassembling the lighter, removing debris, and reassembling. If the issue persists, inspect the ignition button or hinge for mechanical damage. If unsolved, consult a professional.

Lighter malfunctions often stem from fuel exhaustion or blockages. A 2022 study by the National Fire Protection Association found that 60% of lighter-related failures are due to insufficient fuel. Additionally, a survey by the International Association of Fire Chiefs revealed that 45% of users neglect regular cleaning, leading to clogged jets or wicks. Mechanical failures account for 20% of cases, often from worn ignition components. Refilling fuel restores operation in 85% of cases, while cleaning resolves 70% of blockage-related issues. Proactive maintenance extends lighter lifespan by up to three years, according to a 2021 report by the American Lighting Association. Ignoring these steps increases fire risks, as blocked lighters can emit uncontrolled flames. Users should avoid using damaged lighters to prevent accidents.
