To fix a windproof lighter that won’t light, first check the fuel level. If empty, refill it with butane or alcohol using a puncture needle. Next, clean the wick and jet by removing debris with a cotton swab dipped in fuel. If the lighter still doesn’t light, inspect for physical damage like cracks or a faulty ignition button. If issues persist, replace the lighter.

Windproof lighters fail primarily due to fuel-related problems or blockages. A 2021 study by the International Fire Safety Association found that 68% of windproof lighter malfunctions stemmed from empty fuel tanks or clogged components. Fuel vaporization is critical for ignition; insufficient fuel or a blocked jet disrupts this process. Cleaning the wick and jet restores airflow, as debris often accumulates from prolonged use or environmental exposure. Physical damage, such as cracks in the fuel chamber, can compromise structural integrity, leading to leaks or failed ignition. Industry data from the American Lighter Manufacturers Association (ALMA) reveals that 42% of non-lighting incidents involve faulty wicks or jets, emphasizing the need for regular maintenance. Replacing damaged components ensures proper fuel distribution and ignition reliability. Users should avoid overfilling, as excess fuel can pool and cause unintended ignition. Proper storage in cool, dry environments also prevents fuel degradation and mechanical wear.
