What should I do if my S.T. Dupont Lighter is not igniting post-refill?

If your S.T. Dupont Lighter is not igniting after a refill, don’t worry; it’s a common issue and can usually be resolved with some troubleshooting. Here are steps to take:

1. Check the Valve: Ensure that the filling valve hasn’t been inadvertently damaged or blocked. A malfunctioning valve can impede the flow of gas, preventing ignition. Gently examine the valve for any obstructions or damage.
2. Gas Quality: Always remember that the purity of the gas matters. Using non-recommended or low-quality gas can clog the lighter’s mechanism. Ensure you’ve used the recommended S.T. Dupont butane gas for a clean and reliable burn.
3. Seal Check: Examine the seal. It might not be correctly placed or could be compromised, leading to gas leakage. If the seal is damaged or misaligned, it may be time for a replacement.
4. Ignition Mechanism: The problem might not be with the gas or its flow but with the ignition mechanism itself. Check to see if it’s producing a spark when you attempt to light the lighter. If there’s no spark, the ignition mechanism may require servicing.
5. Pressure Check: Refilling with too much or too little pressure can cause issues. Ensure that the pressure during refilling was within the lighter’s specifications. Overfilling can lead to pressure-related problems.

By systematically going through these checks, you can often pinpoint the issue and take appropriate action to get your S.T. Dupont Lighter to ignite. If the problem persists, it’s advisable to contact an authorized S.T. Dupont service center for professional inspection and servicing. These experts have the knowledge and tools to diagnose and resolve more complex issues, ensuring that your cherished lighter functions flawlessly once again.
