9 Reasons Why Gas Fireplace Keep Going Out & How to Fix Them

A gas fireplace is a great way to create a cozy atmosphere in your home. They are generally easy to maintain and use. You can enjoy the winter with aesthetics all around. However, sometimes a gas fireplace can suddenly refuse to ignite, or if ignited, it may refuse to remain lit. 

Since the gas fireplace is connected with a gas line and electric wire from the back end, it may get into a few technical glitches. So if this happens, you don’t have to worry.

There are a few common reasons why the gas fireplace might not be staying lit; they are listed below;

  • Thermostat issue
  • Pilot light issue
  • Blocked vent
  • Thermocouple issue
  • Defective burner
  • Damaged chimney liner
  • Dirty filters
  • Exhaust fan issue
  • Defective electrical wires

It’s important to troubleshoot and diagnose the issue to ensure the safe functioning of your fireplace. If you cannot identify the problem’s source, it’s best to contact a professional fireplace sweeper for help.

Now, we will explore the most common reasons for a gas fireplace going out in detail and how to fix them.

  • Thermostat Issue

If the thermostat is not set to the correct temperature, the gas lines will not ignite. To fix this, reset the thermostat and check the right temperature. Resetting the thermostat may help your gas fireplace stay lit and run properly.

  • Pilot Light Issue

The pilot light is an essential part of the ignition process; if it’s not working correctly, the fire won’t ignite. To fix this issue, you will have to replace the pilot light and check that it is functioning properly. If your gas fireplace isn’t staying lit, the issue could be related to the pilot light. Fortunately, this is a relatively easy problem to fix, as you can easily replace the pilot light inside the gas fireplace.

  • Blocked Vent 

If debris or dirt is blocking one of the gas lines, it will prevent heat from reaching the thermocouple, a safety mechanism that turns off the gas flow if the appliance is not hot enough. And this blocked vent can obstruct a gas fireplace from working. Additionally, ensure that the vent is not blocked by furniture, curtains, or other objects. If your issue is not due to a blocked vent, it might be time to call in a gas-log fireplace maintenance expert to look at your appliance.

  • Thermocouple Issue

The thermocouple is a safety device that detects the presence of a flame and will shut off the gas flow if it is not present. If there is an issue with the thermocouple, it won’t trigger the ignition of the gas lines and, thus, cause the fireplace to go out. It’s important to remember that this should only be done by a qualified professional, as it can be dangerous if done incorrectly.

  • Defective Burner 

A gas fireplace burner needs to be checked if the burner or igniter is not functioning properly. A defective burner will simply stop the gas supply to the fireplace, and the absence of gas will not allow the fireplace to burn. You’ll need to replace the burner or igniter to fix this problem. It is essential to identify the issue correctly and replace the part causing it, as this will ensure that your gas fireplace continues to function properly.

  • Damaged Chimney Liner 

If the chimney liner is damaged, heat will not be able to escape the home. This can cause a dangerous heat buildup, and a gas fireplace will eventually go out. Replacing the chimney liner or getting the right drafty fireplace solutions would help to fix this issue. Also, ensure that if you’re experiencing issues with your gas fireplace, it’s essential to troubleshoot and diagnose the issue. If you need help finding the solution to your problem, don’t hesitate to reach out for assistance.

  • Dirty Filters 

If the filters are not cleaned regularly, they will become clogged with debris. This will prevent heat from reaching the thermocouple, and the gas fireplace will go out. This is why it is certainly imperative to clean the filters regularly. 

  • Exhaust Fan Issue 

If the exhaust fan is not working, heat will not be able to escape the home. This can cause a dangerous heat buildup, and a gas fireplace will eventually go out. To fix this problem, you’ll need to replace the exhaust fan.  

  • Defective Electrical Wires or Circuit Breaker 

If the electrical wires or circuit breaker are not functioning properly, heat will not be able to reach the gas fireplace properly, and the fireplace will go out. You must replace the electrical wires or circuit breaker to make it work properly. Please note that electricity and gas checking is dangerous, so be sure you get the service from any professional fireplace repairman.  

Other reasons your gas fireplace may keep going out include a cracked gas line, a faulty thermopile, or a blocked chimney. 

A cracked gas line may be caused by corrosion of the pipe material to the line. A faulty thermocouple may need to be replaced if it is not sending the correct signals to your gas valve. 

A blocked chimney can cause a dangerous buildup of combustible gasses in the house and should be checked by a professional fireplace insert repair service immediately.
