Why Do My Gas Logs Keep Going Out? Causes & Solutions

Is your cozy evening by the fireplace constantly interrupted by flickering gas logs? It's frustrating when your gas fireplace keeps shutting off unexpectedly. 

Don't worry, though. This common issue often has simple solutions. Let's explore why your gas logs might be going out and how to keep that warm glow burning steadily.

Why do my gas logs keep going out?

Gas logs may go out due to an insufficient gas supply, a dirty or blocked pilot light, or a faulty thermocouple. Regular cleaning and inspection can usually resolve these issues.

Key Takeaways:

• Common Issues: Gas logs may go out due to insufficient gas supply, a dirty or blocked pilot light, or a faulty thermocouple.
• Solutions: Check the gas supply, clean the pilot light, and inspect or replace the thermocouple.
• When to Call a Professional: Persistent problems, safety concerns, or complex repairs require expert attention.
• Preventive Maintenance: Regular inspections, annual servicing, and keeping the area clean help maintain consistent performance.

Common Causes of Gas Logs Going Out

Insufficient Gas Supply: 

If your gas logs keep going out, it might be due to a lack of gas or an issue with the appliance. First, check if your gas supply is low or if there's an interruption in the line.

Ensure all valves are open and your tank isn't empty. If the problem persists, you may need to fix a gas burner or reset the ignition switch.

Sometimes, the issue lies with the thermopile or sensor in the chimney. For those comfortable with DIY projects, you can try to reset the system, but if you're unsure, it's best to call a professional to inspect and repair your gas log appliance.

Blocked or Dirty Pilot Light:

A dirty or blocked pilot light can cause your logs to extinguish. Dust and debris can accumulate over time, preventing the flame from staying lit. Cleaning the pilot light with a soft brush can usually solve this issue.

Faulty Thermocouple:

The thermocouple is a safety device that shuts off the gas if the pilot light goes out. If it's faulty, it might mistakenly cut off the gas supply, preventing your gas fireplace from staying lit.

To keep your gas fireplace going consistently, you may need to address issues with the thermocouple and pilot flame.

Replacing a worn-out thermocouple is a simple fix that can prevent your logs from going out unexpectedly and ensure your gas fireplace keeps turning on reliably.

Troubleshooting Your Gas Logs

Checking the Gas Supply: 

Start by ensuring your gas supply is sufficient. Make sure the gas valve is fully open and that there’s enough gas in the tank. If you suspect a problem with the gas line, contact your provider to check for any issues.

Cleaning the Pilot Light: 

A dirty pilot light can cause your gas logs to go out frequently. Turn off the gas and allow the pilot light to cool. Then, use a soft brush to gently clean away any dust or debris. Once clean, relight the pilot and observe if the flame stays steady.

Inspecting the Thermocouple:  

The thermocouple is a critical component that senses whether the pilot light is lit. If it’s faulty, your logs may go out even if everything else is working.

To check it, look for a small metal rod near the pilot light. If it’s damaged or worn out, you’ll need to replace it. This is usually a straightforward task, but if you’re unsure, a professional can help.

Relighting the Pilot Light:  

If the pilot light goes out, try relighting it following your fireplace’s instructions. Hold the control knob in the pilot position and use a lighter to ignite the pilot. Once it’s lit, keep the knob pressed for about 30 seconds to ensure the flame stays on.

These troubleshooting steps should help you identify and resolve common issues with your gas logs.

When to Call a Professional

Persistent Issues:  

If you’ve tried troubleshooting but your gas logs still keep going out, it’s time to call a professional. Ongoing problems may indicate a deeper issue with your gas line or fireplace components.

A technician can diagnose and fix problems that aren’t easily visible or accessible.

Safety Concerns: 

Safety should always be your top priority. If you smell gas, hear unusual noises, or notice soot buildup, don’t attempt to fix it yourself.

These could be signs of a serious problem that requires immediate attention. A professional will ensure your fireplace is safe to use and functioning correctly.

Complex Repairs:  

Some repairs, like replacing a thermocouple or fixing gas leaks, are best left to experts. Attempting these on your own can lead to more damage or even dangerous situations.

A certified technician has the tools and knowledge to handle complex repairs safely and effectively.

Preventive Maintenance Tips

Regular Inspection:  

Make it a habit to inspect your gas logs and fireplace regularly. Check for signs of wear, debris buildup, or any issues with the pilot light.

Catching problems early can prevent your logs from going out unexpectedly.

Annual Servicing:  

Schedule an annual service with a professional to keep your fireplace in top condition. A technician can clean components, check gas lines, and ensure everything is working properly.

Regular servicing can extend the life of your fireplace and reduce the chances of unexpected outages.

It doesn't matter If you have vented model or vent free model such as this model, don't forget to service at least once a year.

Keeping the Area Clean:  

Keep the area around your gas logs clean and free from dust and debris. Dirt can clog the pilot light and other components, causing your logs to go out. A quick wipe-down and occasional vacuuming can help maintain a consistent flame.
