What Causes A Gas Fireplace to Shut Off?

You probably use a gas fireplace because you enjoy the convenience, beauty, warmth and reliability. But occasionally, you may experience the appliance simply shutting down for no apparent reason.

gas fireplaces in Myrtle Grove, FLDoodlebuggers Fireplace, Grill & Outdoor Store of Pensacola, FL, and Destin, FL, does a lot of installation and repair work on various models of gas fireplaces, and we can tell you that if your fireplace just stops on its own, there’s definitely a reason for it. Here are some of the possibilities.

Thermostat setting

You may need to turn your fireplace thermostat up to engage the fire.

Burner malfunction

A damaged burner or igniter will cause the fireplace to shut down by stopping the flow of gas. Burner malfunction is a common reason for a gas fireplace to shut off on its own.

Pilot light issues

If the pilot light keeps going out, it will cause the fireplace to stop and start. Your owner’s manual may cover some pilot light troubleshooting basics. If you can’t resolve the problem, have the issue looked at by your fireplace technician.

Vent blockage

If the fireplace’s vent is blocked, the thermocouple will turn off the appliance as a safety measure. Make sure nothing is blocking the vent opening. If the problem persists, have your vent system inspected for particulate buildup, which can be cleaned out.

Too little oxygen

The oxypilot in your fireplace will shut the system down if too little oxygen is present in the burning environment. Oxygen allows gas to burn safely; without enough of it, deadly carbon monoxide is created.

Buildup on filters

Dirty gas fireplace filters can keep heat from getting to the thermocouple and cause the fireplace to stop working. Check your owner’s manual for the optimal filter cleaning schedule.

Trouble with the thermocouple

A damaged thermocouple will shut down the appliance if it doesn’t detect a flame. This component should only be inspected and repaired (or replaced) by a trained technician.

Damaged exhaust fan

If the exhaust fan can’t send heat away from the fireplace, heat will build up and cause the appliance to move into safety shutdown mode.

Problems with electrical wiring

A gas fireplace won’t work if there is damage to the electrical wiring or problems with the circuit breaker that serves the appliance.

Gas line issues

If your gas lines are leaking or obstructed, gas won’t reach your fireplace, causing it to stop working. A damaged thermopile, which regulates the flow of gas to the fireplace, can also cause a shutdown.

Gas fireplace inspections

While gas fireplaces are simple to use and easy to maintain, they do need professional inspections by a trained technician once a year. Your inspector will check all parts and components of the fireplace, looking for early signs of damage and malfunction.
