Why Does My Gas Fireplace Keep Going Out? 

If you’re having trouble keeping your gas fireplace going, there are several things to check. One of the more important is the pilot light. It’s one of the main components of the fireplace and can be the culprit for a faulty burner assembly. You’ll want to keep it clear of dust and debris to avoid a fire in your house. 

Another oomph is the thermopile. This component controls the flow of gas into the burner ports. When the pilot is lit, the thermopile is heated, allowing gas to pass through. The thermopile is responsible for monitoring the heat produced by the flame and providing the correct amount of gas to the pilot light. 

A good thermopile can last for decades, but normal wear and tear can leave it vulnerable to carbon deposits and other debris. Cleaning it will restore its functionality. However, you should be aware that messing with the gas lines is not recommended unless you’re an experienced professional. 

While it’s possible to fix your own gas fireplace, it’s better to hire a company that can do the work for you. Gas fireplace problems can range from a dirty pilot to a faulty thermostat and more. An experienced technician can pinpoint the source of your trouble and suggest a solution. 

Checking the pilot is the first step in fixing a faulty gas fireplace. The pilot light is an integral part of the unit. When it is working properly, you’ll see a blue glow. You’ll also be able to light the burner. But if the light doesn’t seem to be getting any brighter, it’s time for a more advanced examination. 

A multimeter may be the tool for the job. Ideally, you’ll place the multimeter’s leads on the TH and TP terminals on the main gas control valve. With the multimeter in place, you’ll be able to find out if the thermopile’s output is the right size to get the pilot lit. 

You can test this by running a pilot light for a few minutes. The thermopile will be triggered and you’ll see what you’re looking for. During this time, you’ll also be able to see if the tiniest bit of gas is getting into the pilot light. 

There are more than a few things to check and a little testing can help you to figure out why your gas fireplace isn’t heating up. Taking the time to look into the details can help you to save money and to be more prepared when the flue or valve isn’t working correctly. 

To be sure that the thermopile is the problem, you might want to consider replacing it. Using a company that specializes in fireplaces can make the task easier. They can also help you identify any other issues you might have, and recommend a solution. 

Finally, check the valve to ensure that it is properly set. Having the correct gas pressure is essential to keeping your fireplace working. Otherwise, it could stay on and not burn efficiently.
