Gas Fireplace Won’t Turn On? Common Issues & Fixes

When colder weather arrives in Rochester, NY, turning on your gas fireplace for the first time of the season should be simple. But after sitting unused for several months, your fireplace may not start as expected. If your gas fireplace won’t turn on, a few common issues could be behind the problem.

Why Won't My Gas Fireplace Turn On?

From a simple control issue to a problem that needs professional attention, there are several reasons your gas fireplace might not start at the beginning of the colder season.

• Pilot light is out: If your fireplace has a standing pilot light, it may have gone out while the fireplace wasn't being used. Without a working pilot light, the main burner won't ignite.

• Remote or switch issue: Dead remote batteries, incorrect settings, or a problem with the wall switch can prevent the fireplace from receiving the signal to turn on.

• Gas supply problem: If the gas supply is turned off or interrupted, your fireplace won't have the fuel it needs to ignite.

• Dirty fireplace components: Dust, dirt, and debris can collect around the pilot assembly, burner, or other components while your fireplace sits unused and may interfere with ignition.

• Ignition or component failure: Problems with the igniter, thermocouple, thermopile, or another internal component can keep an older gas fireplace from starting properly.

How to Troubleshoot a Gas Fireplace That Won't Turn On

Before scheduling gas fireplace service, there are a few basic troubleshooting steps you can try. If you smell gas, notice damaged components, or aren't comfortable inspecting your fireplace, stop using it and contact a professional rather than attempting repairs yourself.

1. Check the Fireplace Controls

Start by checking that the fireplace's wall switch, remote, thermostat, or control panel is set correctly. If you use a remote, try replacing the batteries and make sure the receiver has power.

2. Check the Pilot Light

If your fireplace uses a standing pilot light, look to see whether it's lit. Follow the manufacturer's instructions for your specific fireplace if you need to relight it. If the pilot won't light or repeatedly goes out, it may be time to have the fireplace inspected.

3. Make Sure the Gas Supply Is On

Check whether the fireplace's gas supply valve is in the correct position. If you're unsure how to check the gas supply or suspect there's a problem with the gas line, don't try to repair it yourself. Contact a qualified professional.

4. Look for Visible Dirt or Debris

After months without use, dust and debris may have collected around your fireplace. You can check for obvious buildup around accessible areas, but avoid taking apart the burner, pilot assembly, or other gas components to clean them yourself.

5. Schedule a Professional Fireplace Inspection

If you've checked the basic controls and your gas fireplace still won't turn on, the problem may involve an internal component. Professional fireplace maintenance can help identify issues with the fireplace, determine what's preventing it from starting, and address problems before you use it throughout the colder months.
