Gas Fireplace Repair — Pilots, Igniters, Valves, and Burners
Gas fireplace won't light, keeps going out, or burns wrong? Same-visit fixes and annual service by certified technicians.
Most dead gas fireplaces fail for one of four reasons: a thermocouple or thermopile that has worn out, a pilot assembly clogged with dust, an igniter that no longer sparks, or a wall switch or remote that has stopped responding. When these parts fail, the fix is straightforward and affordable—but only if your technician arrives with the right components on the truck. Ours do.
Chimney Pros handles all major gas fireplace brands: pilot and ignition systems, gas valves, burners, blowers, remotes, and glass doors. Every repair visit includes a burn test and a carbon monoxide safety check. If your unit hasn't been serviced in several years, we offer annual maintenance—burner and log cleaning, glass cleaning, and a complete safety inspection—to restore it to like-new operation.
Warning signs it can't wait
- Pilot light ignites but won't stay lit after you release the button
- Clicking or ticking sound from the control box when you try to light it
- Burner flames are yellow or orange instead of blue
- No spark at the electrode when the ignition switch is turned on
- Remote control doesn't respond even after fresh batteries
- Faint gas smell near the fireplace when the unit is off
- Blower motor runs but burner doesn't ignite
- Wall switch is unresponsive or the wall plate is cracked
Seeing two or more at once? Stop using the fireplace and call — that combination usually means the system is struggling or unsafe to run.
Common gas fireplace problems
- Thermocouple — the sensor that signals the gas valve; weakens with age and heat cycling
- Thermopile — generates its own electrical signal; fails after years of use and temperature stress
- Pilot assembly — becomes clogged with dust, pet hair, or spider webs that block gas flow
- Igniter electrode — corrodes or breaks, preventing spark at the burner or pilot
- Gas valve — controls gas flow; fails internally and may not respond to the thermocouple signal
- Burner — accumulates dust and soot that changes flame pattern and can cause incomplete combustion
- Wall switch — loose contacts or water damage inside the switch housing stops it from working
- Remote receiver — loses pairing or corrodes; no longer communicates with the handheld remote
- Blower motor — runs but fails to push heated air into the room; typically a bearing failure
What gas fireplace repair costs
Most gas fireplace repairs fall between $180–$450. The diagnostic is $99 and applies toward your repair if you move forward. One flat quote is approved before any work begins, and there are no trip fees.

| Thermocouple replacement | $195 – $265 |
| Thermopile replacement | $220 – $310 |
| Igniter electrode replacement | $185 – $250 |

What you get
Certified Gas Techs
Trained on gas hearth systems and carrying the common failure parts — thermocouples, thermopiles, igniters — on the truck.
Same-Visit Fixes
Most repairs are diagnosed and completed in one visit, because the parts came with us.
CO Safety Tested
Every repair and tune-up ends with a carbon monoxide and venting safety check.
Annual Maintenance
A yearly service keeps the flame pattern right, the glass clear, and the safety systems verified.
Gas fireplace tune-up
Burner and log cleaning, glass cleaning, and a full ignition + CO safety test — book it once a year and it lights every time.
How it works
Phone intake and scheduling
You describe the symptom—no spark, pilot won't hold, smell, remote dead. We ask a few follow-up questions and book you for same-week service, often same-day.
Technician arrives and inspects the unit
We examine the pilot assembly, igniter, gas valve, and control board. We look for visible soot, dust, loose connections, and corrosion that point to the root cause.
Diagnostic and safety test
We power on the system to watch what happens—or doesn't. We measure gas pressure, check electrical continuity, and test for carbon monoxide. The diagnostic fee is $99 and applies to your repair if you move forward.
Repair and parts replacement
We replace the failed component—thermocouple, valve, electrode, or other part—using quality replacements we carry on the truck. We reassemble and prepare for the test burn.
Burn test and CO check
We light the fireplace, watch the flame pattern and color, let it run for a few minutes, and measure carbon monoxide at the flue opening. We document the results in photos.
Walkthrough and invoice
We show you the before-and-after photos of the unit, explain what we repaired, review the one flat quote you approved at the start, and leave you with documentation of the service.
Gas Fireplace Repair questions
Why won't my pilot light stay lit?
In most cases, the thermocouple or thermopile—the sensor that tells the gas valve the pilot is burning—has reached the end of its life. It's one of the most common and least expensive repairs we make. Your technician carries replacements on the truck.
Does a gas fireplace really need annual maintenance?
Yes. Dust, pet hair, and spider webs collect in the pilot and burner ports, flame color drifts, and your safety systems stay untested. An annual cleaning and tune-up keeps the unit lighting reliably and catches venting or carbon monoxide issues before they become serious.
What should I do if I smell gas?
Don't investigate or troubleshoot—leave the house immediately and call your gas utility's emergency line from a neighbor's phone or outside. Once the utility confirms it's safe to return, we can diagnose and repair the problem.
My remote stopped working—is that worth a service call?
Often it's just dead batteries or a receiver that needs to be re-paired, and we're happy to walk you through that by phone first. If the receiver module or wall switch has actually failed, we replace it in one visit—usually paired with an annual tune-up so the trip covers both.
Who fixes gas fireplaces—plumbers, electricians, or chimney companies?
Gas fireplace repair lives at the intersection of gas, electrical, and venting—which is why a qualified fireplace or chimney company is your best choice. We understand the complete system: ignition, fuel delivery, combustion, and ventilation.
Can I replace a thermocouple myself?
Thermocouples are straightforward parts, but working inside the control assembly and gas lines requires care and proper tools. A service visit—$99 diagnostic, $195–$265 for replacement—is safer and faster than a DIY attempt that could damage nearby components.
How much does it cost to fix a gas fireplace?
Most repairs range from $180–$450, depending on the part. A pilot assembly cleaning runs $180–$220; a thermocouple replacement, $195–$265; a gas valve, $320–$450. Your diagnostic is $99 and rolls into the repair cost if you approve the work.
What if the pilot lights but the burner won't ignite?
The igniter electrode, gas valve, or burner itself could be the culprit. We run a diagnostic to isolate which component has failed—igniter replacement is typically $185–$250; burner cleaning, $180–$230.
Do you charge a trip fee if it's just a small fix?
No. There are no trip fees. You pay only the diagnostic ($99, credited if you proceed) and the repair itself. Same-day and emergency service are available, and we schedule suspected gas-smell calls first.
