A gas fireplace has a different set of problems from a wood one. Instead of creosote and brick, the failures are in the ignition and control system: a pilot that will not stay lit, a worn thermocouple or thermopile, a valve that does not open, a wall switch or remote that no longer talks to the unit, logs shifted off their marks, or glass that fogs and soots. These are the repairs our qualified gas fireplace technician handles, on direct-vent, B-vent and vent-free units, inserts, and gas log sets in a masonry fireplace.
This page is for homeowners whose gas fireplace will not light, will not stay lit, burns wrong, smells, or has not been serviced in years. If the problem is in the chimney or chase around a gas unit rather than the unit itself, see chase repair or chimney inspection.
We service gas fireplaces across Seattle, Tacoma, Everett and King, Pierce and Snohomish counties from our Renton office. The quote is free, and same-day service is often available.
Symptoms
Signs you need gas fireplace repair
- Pilot light goes out on its own, or will not light at all
- Pilot stays lit but the main burner will not come on
- Fireplace lights, then shuts off after a few seconds or minutes
- Wall switch, remote or thermostat no longer turns the fireplace on
- Flames mostly blue, lazy, lifting off the burner, or much smaller than before
- White haze or black soot on the inside of the glass
- Clicking from the igniter with no flame
Common causes
- A worn thermocouple or thermopile that no longer produces enough signal to hold the valve open
- A pilot assembly clogged with dust, spider webs or corrosion
- A gas valve, ignition module or switch that has failed or lost its connection
- Logs or embers placed out of position, which disrupts the flame and soots the glass
- A blocked or disconnected vent that trips the safety shutoff
How It Works
Our gas fireplace repair process
Our technician opens the control compartment and works through the system in order: gas supply, pilot flame, thermocouple or thermopile output, valve operation, wiring and switches, burner and log placement, glass gasket, and vent. Most no-light calls come down to one of the first four, and a meter reading tells us which. You get a plain-language explanation and a written quote before any part is replaced.
Free diagnostic quote
Our qualified technician tests the pilot, thermocouple or thermopile, valve and ignition circuit, and tells you which part has failed and what it costs to fix.
Clean the pilot and burner
The pilot assembly, burner ports and orifice are cleaned of dust and corrosion, which alone resolves many pilot and flame complaints.
Replace the failed part
Thermocouple, thermopile, igniter, receiver, switch or valve is replaced with the correct part for the unit.
Reset logs and clean the glass
Logs, embers and media are placed to the manufacturer's pattern, the glass cleaned, the gasket checked, and the vent confirmed clear.
Test and walkthrough
We run the fireplace through its full cycle, check for leaks at the connections we touched, and show you how to operate it.
Options
Repair and service options
Gas fireplace repairs are priced per component, and our technician tells you which apply before starting:
- Pilot and ignition service: cleaning the pilot assembly and replacing a worn thermocouple, thermopile or spark igniter. The most common fix for a fireplace that will not light or stay lit.
- Control repair: replacing a failed wall switch, remote receiver, ignition module or gas valve.
- Annual gas fireplace service: a full clean of the pilot, burner, logs and glass plus a safety check, for fireplaces that run but have not been opened in years.
- Log and media reset: repositioning or replacing logs and embers that have shifted or crumbled, which fixes sooty glass and lazy flames.
- Glass and gasket: cleaning hazed glass and replacing a worn gasket on a direct-vent unit so the sealed chamber stays sealed.
- Vent check: confirming the vent is clear, connected and terminated correctly, with chase and cap work quoted separately.
Every quote is free and in writing, and we price match any written quote plus 10-25% off.
Pricing
What affects the price
- Which component has failed: thermocouple, thermopile, igniter, receiver, switch or valve
- Make and model of the unit and whether parts are stock or must be ordered
- Direct-vent, B-vent or vent-free unit, or a log set in a masonry fireplace
- How long since the last service and how much cleaning the burner and pilot need
- Whether logs, embers or glass media need replacing
- Distance from Renton for outlying Pierce and Snohomish addresses

Safety & Seattle Conditions
Safety considerations
If you smell gas, do not try to find the source and do not operate the fireplace, any switch, or anything that could spark. Leave the house, and call your gas utility or 911 from outside. We will come once the utility has made the home safe.
For everything short of a gas smell, leave the gas side to our qualified technician. Do not open the valve, try to relight the pilot, adjust the logs or work on the gas line yourself. A gas fireplace that shuts itself off is usually a safety device doing its job; stop using it and have it looked at. NFPA 211 recommends an annual inspection of chimneys, fireplaces and vents, gas units included.
Seattle & Puget Sound conditions
Gas fireplaces run hardest in Puget Sound during the same months the rain does. Sea-Tac's NOAA 1991-2020 normals put October through March at about 29.65 inches of precipitation, roughly 73% of the 40.34-inch annual total, and many homeowners use a gas fireplace as daily heat through that stretch. A unit that has not been serviced is most likely to fail in November, the wettest month at 6.31 inches, when it is needed most.
The housing mix points the same way. Renton's median home dates to 1988, Redmond's to 1993 and Gig Harbor's to 1998, and factory-built fireplaces are common in homes from that era, so many fireplaces in newer neighborhoods are reaching the age where pilot and control parts wear out.

Gas Fireplace Repair FAQ
Why won't my gas fireplace pilot stay lit?
The most common reason is a worn thermocouple or thermopile. That small sensor sits in the pilot flame and generates the signal that holds the gas valve open; when it weakens, the valve closes and the pilot drops out. A clogged pilot assembly or a pilot flame that is too small does the same thing. Our technician tests the sensor, cleans the pilot, and replaces the part if it is out of range.
My gas fireplace lights but goes out after a few minutes. What is wrong?
A fireplace that lights and then shuts down is usually a safety device responding to something: a weak thermopile under load, a loose wire at the valve, a vent problem, or an overheating sensor. Stop using it and have it diagnosed rather than relighting it. The repair is often a single part once the cause is found.
What should I do if I smell gas near the fireplace?
Leave the house. Do not operate the fireplace, light switches or anything that could make a spark, and do not try to find the leak. From outside, call your gas utility or 911. Once the utility has checked and cleared the house, call us and we will find and fix the fault in the fireplace.
Why is the glass on my gas fireplace cloudy or black?
A white haze is mineral deposit from combustion and cleans off during a service. Black soot means the flame is touching something it should not, almost always logs or embers moved off their marked positions, or a burner that needs cleaning. We reset the logs to the manufacturer's pattern, clean the burner and glass, and check the gasket.
Do gas fireplaces need annual service?
NFPA 211 recommends an annual inspection of chimneys, fireplaces and vents, and that includes gas units. A yearly service keeps the pilot and burner clean, catches a weakening thermocouple before it strands you in November, and confirms the vent is clear. Most failures we see come from units that have not been opened in years.
Do you service gas fireplaces the same day, and is it guaranteed?
Often, yes. Pilot cleaning, thermocouple and thermopile replacement, receiver problems and log resets are usually finished on the first visit when the part is in stock; a valve or model-specific module may need ordering. If you are not happy, we are not done, and we re-do the repair at no charge. We also give free second-opinion quotes and price match plus 10-25% off.
