A clogged or faulty burner can cause performance issues resulting in a low gas flame. In addition, carbon build-up, gas residue, and debris can inhibit the burner's ability to function correctly, leading to premature failure. If cleaning the burner doesn't solve the problem, it may need to be replaced.
You could be dealing with a bad thermo couple/ thermo pile. The thermo couple is a sensor that senses heat and allows the pilot light to remain lit, the thermo pile allows gas to pass through the burner system and provide light and heat. You could be dealing with a bad one or it could be shorting out some where.
One of the most common problems faced by homeowners with gas fireplaces is the pilot light going out or not staying lit. The pilot light is a small flame that ignites the gas burner, which produces the heat for your fireplace — if the pilot light goes out, your fireplace won't work.
If your gas fireplace refuses to turn on, begin to troubleshoot by checking that the gas supply valve is fully open. If it isn't, simply open it and try again. Then, ensure that the pilot light is lit – more on that soon. If the problem persists, examine the electrical components.
Thermocouple issues, pilot light problems, blocked venting systems, safety features, and gas supply issues are common reasons why gas fireplaces shut off. Regular maintenance, cleaning, and professional servicing are essential to prevent unexpected shut-offs.
Gas fireplaces have a fuse for the electronic ignition system, and a power surge may have tripped the circuit breaker preventing your gas fireplace from igniting.
But in general, an efficiently running modern gas fire kept clear of dust and debris should hit or exceed that 10 to 15-year mark before showing signs of wear. Older or cheaper models may start to struggle after 7–8 years. Regular servicing and maintenance will be essential to maximising lifespan potential.
Common causes include problems with the pilot light, thermocouple, gas supply, obstructions, ignition system, gas pressure, and weather conditions. While some issues can be resolved with basic troubleshooting, others may require professional assistance.
Gas fireplace repair costs can range significantly from $400 to $1500, depending on the problem you face.
Electrical Issues: Loose Wiring or Faulty Connections
Electrical problems are one of the most common causes of a gas fireplace switch not working. If the wiring is loose or corroded, the signal won't reach the ignition system.
Generally, the reset button can be found inside the air handler, which is either next to or above the furnace. To access it, you'll need to open the air handler compartment, which may pop off or require removing screws to take off the door.
Press the control knob down and hit the ignition switch.
To ignite the pilot light, press your finger into the center of the control knob and hold it in place. Then, hit the fireplace's ignition switch, which is typically a red button located near the control knob. Tap the switch until the pilot light ignites.
If your own troubleshooting fails to solve the problem, you should call a fireplace service company near you for help. Most service calls for gas fireplaces cost about $100, and repairs for pilot lights cost $150 on average.
You start smelling strange odors
This smell should go away after three to four hours of use. A dirty fireplace with excessive pet hair or dust can also produce an odor. If you smell rotten eggs, call for help immediately, as you likely have a gas leak.
Pilot Light: Start by checking the pilot light. If it is out, resetting it could be all you need to fix the problem. Thermocouple/Thermopile/Oxygen sensor: Next, check each of these sensors to make sure they are functioning properly. Start with the thermopile to see if the valve is letting gas in.
Fireplace thermocouple replacement costs $150 to $350 total. The thermocouple sends electrical signals that open and close the valve, which controls the flow of the gas.
The National Fire Protection Association (NFPA) recommends all fireplace owners with solid or liquid fuel appliances have annual safety & maintenance inspections. While gas fireplaces burn cleaner than wood, yearly safety and maintenance inspections are still essential to ensure they operate safely.
A quality gas fire will last years but over time our tastes change, and we want to update the fireplace with something more modern and in keeping with our current décor. The beauty of gas fires is that with the help of a Gas Safe engineer, they can be easily replaced for a newer model.
How Long Can a Gas Fireplace Last? Generally speaking, you can get a good ten to fifteen years of use before you need to replace your gas fireplace.
Many gas fireplaces rely on an electrical ignition. If your gas fireplace isn't lighting, it might be because the circuit breaker it is on has been tripped. Check the breaker box to make sure that none of the circuit breakers have flipped off. If any are, flip them back on.
It can be done, but it's worth looking at all options before committing to repair. Repairing your gas fireplace may be the better option if: The existing fireplace still fits your home aesthetically. There's a minor mechanical problem or broken part.
