Why Does My Gas Fireplace Keep Going Out?

A gas fireplace is a cozier addition to a home, providing warmth and ambiance without the hassle of wood-burning alternatives. However, nothing can be more frustrating or concerning than a fireplace that suddenly goes out. If you’re experiencing this issue, we’re here to help! In this article, Chimney Doctors explains why your gas fireplace keeps going out.

Ignition Assembly Components

At the heart of most gas fireplace issues is the ignition assembly, which includes the pilot light assembly, thermocouple, and thermopile. These components are crucial for the ignition and functioning of your gas fireplace. Any issues with these units can prevent the fireplace from staying lit.

Pilot Light Issues

A frequent culprit for a gas fireplace that won’t stay lit is the pilot light. This small blue flame must be in proper contact with the sensors—namely, the thermocouple and thermopile—to ensure it ignites correctly. If you observe a weak, yellow, or red flame, the gas may be contaminated, or the pilot light may require cleaning or replacement.

Understanding the Thermocouple and Thermopile

The thermocouple and thermopile serve different but complementary functions. The thermocouple is a safety device that closes the gas valve if the pilot light goes out. On the other hand, the thermopile generates the voltage necessary to open the gas valve when the fireplace is turned on. Therefore, testing these components with a multimeter is essential. If their voltage is under the expected levels, cleaning or replacing them might be necessary.

Other Gas Fireplace Issues

If your fireplace is still turning off after checking the aforementioned and finding them in order, you may be experiencing other issues, such as:

• Gas Service Pressure. Incorrect gas service pressure could lead to your fireplace going out. Technicians can identify and rectify the pressure settings for you.
• Drip Loop Issues. Moisture in the gas line can affect the drip loop, diluting the natural gas and, consequently, the fireplace’s ability to stay lit.
• Faulty Gas Valve. Though rare, a faulty gas valve could cause the gas supply to be intermittent or cease altogether, affecting the fireplace’s operation.

Professional Inspection and Cleaning

Instead of attempting to fix your gas fireplace, consider a professional inspection and cleaning. A thorough inspection involves the technician evaluating all components, including flue liners and hidden areas. Proper cleaning is also vital in ensuring the safety and efficiency of your chimney system, which directly affects your gas fireplace’s performance.
