How Do You Fix a Gas Fireplace That Keeps Going Out

A gas fireplace can be a cozy and convenient addition to your home, providing warmth and ambiance during the colder months. However, if your gas fireplace keeps going out, it can quickly become frustrating and even potentially dangerous. Here are some common causes and solutions to fix a gas fireplace that keeps going out.

1. Check the Pilot Light: The pilot light is a small flame that ignites the gas in your fireplace. If it goes out, the fireplace will not stay lit. Make sure the pilot light is lit and burning steadily. If it is not, follow the manufacturer’s instructions to relight it. If the pilot light keeps going out, it may be due to a dirty or faulty thermocouple.

2. Clean the Thermocouple: The thermocouple is a safety device that detects if the pilot light is burning. If it senses that the pilot light is not on, it will automatically shut off the gas supply to prevent a dangerous gas buildup. A dirty or faulty thermocouple can cause the gas fireplace to keep going out. Gently clean the thermocouple with a soft brush or replace it if necessary.

3. Check the Gas Supply: A gas fireplace that keeps going out may have an issue with the gas supply. Check that the gas valve is fully open and that there are no obstructions or leaks in the gas line. If you suspect a gas leak, immediately turn off the gas supply to the fireplace and contact a professional technician.

4. Inspect the Venting System: Improper venting can cause the gas fireplace to go out. Check that the venting system is not blocked or obstructed by debris, animals, or other objects. Ensure that the chimney or flue is clear and functioning correctly. If you notice any issues with the venting system, consult a professional for assistance.

5. Clean the Burners and Logs: Over time, dust, debris, and soot can accumulate on the burners and logs of your gas fireplace, causing them to not function properly. Clean these components regularly with a soft brush or vacuum to ensure optimal performance. Follow the manufacturer’s instructions for cleaning and maintenance.

6. Adjust the Flame Sensor: The flame sensor is another safety device that detects whether the gas is burning. If it does not sense a flame, it will shut off the gas supply. A misaligned or dirty flame sensor can cause the gas fireplace to keep going out. Adjust the position of the flame sensor or clean it gently with a soft cloth to fix the issue.
