Kime Brittain, Owner — NOVA Gas Works | Licensed Master Gasfitter, VA & MD • September 17, 2025

Having a gas fireplace can be a great way to add warmth and ambiance to your home. But it can be frustrating if you have a gas fireplace (that is) not turning on. There are several common reasons why a gas fireplace may not ignite, and fortunately, there are also solutions to these problems. 


Here, we will explore some of the most common reasons why gas fireplaces fail to turn on and provide some solutions to help get your fireplace up and running again.

Common Gas Fireplace Problems

Gas fireplaces are complex systems that require a number of components to work together in order for the fireplace to function properly. There are a variety of issues that can cause a gas fireplace to fail to ignite. Here are some of the most common problems:

Pilot Light Issues

One of the most common reasons why a gas fireplace won’t turn on is a problem with the pilot light. The pilot light is a small flame that ignites the main burner of the fireplace. If the pilot light is out or not functioning properly, the fireplace will not ignite. There are several potential reasons why the pilot light may not be working, including a clogged pilot tube, a faulty thermocouple, or a gas supply issue. It is important to inspect the pilot light and make sure it is clean and properly aligned. If you are unsure of how to do this, it is recommended to contact a professional gas service provider like NOVA Gas for assistance.

Gas Supply Issues

Another common reason why a gas fireplace may not turn on is a gas supply issue. If there is a problem with the gas supply to the fireplace, it will not ignite. This can be caused by a variety of things, such as a gas leak, a closed gas valve, or an issue with the gas line. It is important to check the valve and make sure it is fully open. If there is a gas leak or an issue with the gas line, it is recommended to contact a professional gas service provider like NOVA Gas for repairs.

Electrical Issues

Some gas fireplaces rely on electricity to ignite and operate. If there is an electrical issue, like a blown fuse or a tripped circuit breaker, the fireplace may not turn on. It is important to check the electrical connections and make sure that all components are receiving power. If there is an electrical issue you are unable to resolve, it is recommended to contact an electrician or professional gas service provider like NOVA Gas for assistance.

Faulty Igniter or Control Panel

In some cases, the issue may be related to a faulty igniter or control panel. If the igniter or control panel is not working properly, the fireplace will not ignite. This can be caused by normal wear and tear, a manufacturing defect, or other factors. It is recommended to contact a professional gas service provider like NOVA Gas to diagnose and repair any issues with the igniter or control panel.



If your gas fireplace is not turning on, there are several solutions you can try before contacting a professional gas service provider like NOVA Gas.

Check the Gas Supply

First, check the gas supply to make sure the valve for the gas is fully open. If the valve is closed, open it and try turning on the fireplace again. If the valve is free but there is still no gas flowing to the fireplace, there may be a gas supply problem that requires professional attention.

Inspect the Pilot Light

If the gas supply is not the issue, inspect the pilot light. Make sure the pilot light is clean and properly aligned. If the pilot light is out, try relighting it. If it still does not ignite, the pilot tube, thermocouple, or gas supply may require professional repair.

Check the Electrical Connections

If your gas fireplace relies on electricity, check the electrical connections and make sure that all components are receiving power. If there is an electrical problem, such as a blown fuse or a tripped circuit breaker, resolve the issue and try turning on the fireplace again. If the electrical problem persists, it is recommended to contact a professional gas service provider for further assistance.
