As temperatures in the Bay Area drop and your gas fireplace becomes a household staple, it can be easy to take this cozy convenience for granted. However, ignoring the signs of wear and tear on your beloved gas fireplace can not only compromise the comfort of your space but also pose potential safety risks. Use this guide to learn some of the biggest signs your gas fireplace needs maintenance, so you can enjoy safe and energy-efficient heating in your home with peace of mind all season long.

Pilot Light Isn’t Working

One of the most noticeable signs a gas fireplace needs professional maintenance is pilot light issues. Every gas fireplace has a built-in pilot light, which is a small flame that ignites when you turn the appliance on. When working properly, the small pilot light flame is designed to stay lit all the time. 

If your fireplace pilot light won’t stay lit, it may be due to a worn-out thermopile, which is an essential mechanism that controls the flow of gas. Wiring issues or a gas valve blockage could also cause issues with a gas fireplace pilot light. If you’ve already followed the manufacturing instructions and your pilot light still won’t stay lit, it’s time to call a professional fireplace service technician for maintenance.

Soot Buildup

Gas fireplaces are incredibly clean-burning and can run for hours and days at a time without producing any smoke, soot, or ash. Fireplace soot is a black powdery residue that accumulates on surrounding surfaces. A gas fireplace should never produce any kind of soot or other fuel byproduct.

Soot buildup on the glass doors of a gas fireplace means something is very wrong, and professional maintenance is required immediately. Soot in a gas fireplace typically indicates a problem with the gas fuel and oxygen mixture, which could be caused by a number of different things:

  • Incomplete combustion happens when there isn’t enough oxygen present to completely burn the fuel. As a result, carbon particles (soot) are produced instead of carbon dioxide. 
  • Faulty gas burners don’t provide enough gas to mix with the oxygen, which creates an imbalance that can eventually lead to incomplete combustion and soot formation. 
  • Obstructed ventilation such as a dirty or blocked flue can restrict the flow of gases and prevent proper circulation, causing soot to build up.

It’s important to address this issue promptly to ensure your gas fireplace is safe to use. If you notice soot buildup, contact a professional for gas fireplace maintenance as soon as possible.

Gas Fireplace Switches On and Off

If the flames in your gas fireplace won’t stay lit, the problem could be caused by a number of things that may be easy to troubleshoot using the manufacturer’s manual. However, if your gas fireplace continues to turn on and off this issue is most likely related to the ignition assembly. This typically includes the pilot light, a thermocouple, and a gas valve.

The thermocouple is a safety device designed to detect whether the fireplace pilot light is lit. If no flame is sensed, it sends a signal that shuts off the gas valve and cuts off the gas supply. This prevents potential gas leaks.

 If the thermocouple is damaged or incorrectly positioned, it won’t be able to detect the pilot light flame, causing the gas valve to close, which turns the fireplace off. A blockage in the fireplace gas valve might also be the issue. Without a consistent gas flow, the flame will go out.

Whatever the reason behind your gas fireplace switching on and off, call a professional for gas fireplace repair services to safely diagnose and fix the issue.

Rotten Egg Smell

Noticing a rotten egg smell coming from your gas fireplace is a sign of immediate danger– a gas leak. This odor is caused by a harmless but strong-smelling chemical called mercaptan, which is added to natural gas to act as a warning sign of a leak.

If you suddenly smell rotten eggs around a gas fireplace, evacuate the home immediately and call emergency services.
