Fortunately, most gas fireplace issues are easy to fix! You can check the breaker box and reset any tripped breakers to see if it’s an electrical problem. If it’s not, you can open the gas valve to restore gas flow before calling a professional. 

Pilot Light Not Staying Lit

One of the most common reasons that your gas fireplace won’t stay lit is due to a pilot light that isn’t able to stay on. This can be caused by a number of different things, including a strong draft in your chimney or a pilot light that is clogged with dirt and soot. To avoid this problem in the future, it’s important to follow your manufacturer’s instructions on how to light the pilot and clean the orifice every year. 

Test Your Pilotlight

First, try to manually ignite your pilot light. To do this, simply turn on the switch and hold it for 60 seconds. If you hear a click when the switch is turned on, your pilot light has likely failed. 

If the pilot light doesn’t work, it could be because your thermocouple or thermostat isn’t functioning correctly. These two components are vital to the ignition system in your fireplace, and a bad or damaged one can cause your pilot light to not light. 

A thermocouple is a small piece of heat-sensitive metal that acts as a bridge between your pilot light and the gas valve. It senses when the pilot light is on, and if it detects that no flame is present, it sends an electrical signal to the gas valve. This opens the gas valve, allowing gas to enter the burner ports and start burning. 

Another possible issue is that your thermostat or timer has stopped regulating your gas fireplace. This can cause your fire to run out of fuel before it can burn completely, making your gas fireplace fail to light. 

If you’re sure that your thermostat and timer are both working correctly, you can try raising the temperature of your gas fireplace to see if it will ignite again. A higher temperature will help your burner to burn more efficiently and can make it easier for you to get a fire started in the future. 

Lastly, if your thermostat is set to a setting that is too low for the flame in your gas fireplace to start, it can also be the cause of your gas fireplace’s failure to light. This is especially true if you use a propane-fueled fireplace, as the lower temperatures cause your propane to burn more slowly and less efficiently than natural gas. 

If you’ve tried all of these solutions, and your gas fireplace still won’t light, it may be time to call a professional for help. A technician can test your circuitry, remove any obstructions in the chimney, and replace parts that aren’t functioning properly. They can even repair your gas fireplace if you need to replace the wiring or thermopile.
