Gas fireplaces have recently become more and more popular among homeowners, and for good reason. They are incredibly easy to operate, as they do not require all the labor of a wood fireplace. Gone are the days of chopping and storing wood, hauling it inside, lighting the fire, and waiting impatiently for the fire to extinguish…gas fireplaces turn on and off at the push of a button! Many gas fireplaces used to look very clunky and fake, which deterred homeowners. However, newer enhanced designs look identical to their traditional wood counterparts! They also produce fewer emissions than other gas lightfireplaces, which significantly reduces the size of your carbon footprint.

Despite their many benefits, gas fireplaces are not immune to the occasional problem and breakdown. Fortunately, homeowners can fix many gas fireplace problems through simple troubleshooting. But when these problems persist and troubleshooting is not enough, it’s time to call a professional. That’s where we come in! SirVent Chimney & Venting Service can fix any gas fireplace problems in the Lexington area! Read below to learn more, then give us a call to schedule an appointment!

Pilot Light

Some of the most common gas fireplace problems involve the pilot light, which is a small gas flame that serves as the fireplace’s primary fuel source. Sometimes this light can go out for a variety of reasons. To check your fireplace’s pilot light, open the vent. A properly functioning pilot light is bright blue, and anything else is cause for concern. If it is another color or extinguished entirely, consult your fireplace’s manual for re-lighting instructions. This is usually fairly simple and can be completed with a match or lighter.

If the pilot light keeps going out after re-lighting, there are other troubleshooting options. You could check the drip loop, which is responsible for catching extra moisture when your fireplace is in use. When it overflows, moisture or condensation leaks onto the gas line and extinguishes the pilot light.

You should also check the vent cap if your pilot light keeps extinguishing. A damaged, loose, or broken vent cap allows drafts to blow out the pilot light, so make sure it’s functional and present.

Thermocouple and Thermopile

The thermocouple and thermopile are two other gas fireplace components prone to malfunctioning. The thermocouple is a small metal sensor that heats up when in direct contact with the pilot light. When the pilot light is turned on and reaches the optimal temperature for a fire, the thermocouple is responsible for telling the gas valve to open. It must be perfectly placed and stable for your fireplace to function properly. A common sign of a thermocouple problem is your pilot light ignites fine but does not stay lit for long. Fortunately, most thermocouple fixes are quite simple. Try cleaning it off and making sure it is tightly screwed in and positioned so it can directly contact the pilot light. You should also check on the wiring.

The thermophile is a metal component that turns heat from the pilot light into electricity. The fireplace not starting despite a lit pilot light is a common sign of a thermophile issue. Similar to the thermocouple, troubleshooting includes cleaning, making sure it is properly positioned, and checking the wiring.


Troubleshooting with the burner can also help solve gas fireplace problems. The burner sits below the pilot light and thermocouple, and it allows gas to flow towards the pilot. Its many small holes become clogged and dirty over time, so start by cleaning them out with soap and water or an air compressor if you notice a weak stream.
