The pilot lights. You think the fireplace is finally working. Then the flame disappears again.
Or maybe your fireplace has a pilot that won't light at all. Either way, it's frustrating to have a fireplace that's supposed to make your home comfortable but can't reliably start.
A pilot problem doesn't automatically mean you need a new gas fireplace. It also doesn't tell you which part has failed. Different ignition systems can produce similar symptoms, and replacing the wrong component won't solve the real problem.
Get the cause checked for $89 with Preston Home Services in Dallas–Fort Worth. If you move forward with a repair through Preston, that $89 diagnostic fee is credited toward the repair.
First, Which Pilot Problem Are You Having?
The pilot won't light at all
On a fireplace with a standing pilot, a failure to light may involve the pilot assembly, ignition component, gas supply or another part of the control system. On a fireplace with electronic ignition, you may not see a continuously burning pilot in normal operation at all.
That's why the model matters. A symptom that sounds like a bad pilot may actually originate elsewhere in the startup sequence.
The pilot lights but goes out
If a pilot flame appears and then disappears, the appliance may not be detecting or maintaining the flame correctly. A dirty or faulty sensing component, a pilot assembly problem or another system issue may be involved. Only a proper diagnosis can distinguish among them.
The pilot stays lit, but the burner won't ignite
This is not quite the same failure. The pilot is operating, but the main burner isn't being allowed to come on. The issue could involve the controls, switch, sensing circuit or gas valve rather than the pilot itself.
The pilot works sometimes and fails at other times
Intermittent failures can be particularly misleading. The fact that it lit yesterday doesn't prove the system is operating correctly today. Make a note of what happens and stop repeatedly trying to force a startup.
Is It the Thermocouple, Pilot Assembly or Igniter?
You may have seen those terms while searching online. They're real components, but not every fireplace uses the same arrangement. Older and newer units can have different ignition and sensing systems.
A diagnosis should start by identifying the exact model, listening to the symptoms and checking the appropriate components. Guessing based on an online video can lead to unnecessary replacement parts, especially if the real issue is in a different part of the control sequence.
What You Can Safely Do Before Scheduling Service
If you don't smell gas and there is no other sign of danger, look up your model's normal operation in the manufacturer's manual. Note whether it uses a standing pilot or electronic ignition, and describe exactly what you see.
You can also note whether your wall switch or remote responds normally. Do not take apart the pilot assembly, clean internal gas components, alter the gas valve, bypass flame-safety controls or repeatedly attempt to relight a malfunctioning unit.
Gas odor or suspected leak? Leave immediately. Do not operate switches or use a phone inside. Call 911 and your gas utility from a safe location. Do not schedule ordinary repair service as a substitute for emergency response.

Pilot Light Repair FAQs
Why does my gas fireplace pilot keep going out?
Several things can cause an unstable pilot or failed flame detection, depending on the ignition system. A professional diagnostic can identify the actual cause instead of replacing parts by guesswork.
Can a bad wall switch look like a pilot problem?
Sometimes a control fault can stop the main burner from starting even though the pilot appears normal. That is why the pilot and burner symptoms need to be distinguished.
How much does a pilot light repair cost?
The repair price depends on the failed component and the work required. Preston's diagnostic is $89, credited toward a repair completed by Preston if you approve that work. You receive repair pricing before additional work starts.
Should I keep trying to relight the pilot?
If the unit is repeatedly failing to light or stay lit, stop attempting to restart it and arrange service. Follow the manufacturer's safety instructions and never try to override a safety control.
