Gas Fireplace Repair Services in Dallas
Gas fireplaces are everywhere in Dallas, from townhomes in Uptown to newer houses in Plano and Richardson. They are easy to use, until the day the pilot will not light or the flame looks wrong. Most problems come from a few small parts that wear out over time.
We test the whole system: the pilot, the safety sensors, the igniter, the valve, the controls and the vent. Then we tell you what failed and what it costs to fix, before we replace anything.
Gas Fireplace Won’t Light? Common Causes
| What happens | Likely cause | What we do |
|---|---|---|
| No click or spark at all | Dead igniter battery or bad igniter | Replace battery or igniter |
| Pilot lights, goes out when you let go of the knob | Worn or dirty thermocouple | Clean or replace the thermocouple |
| Pilot stays lit, burner won’t come on | Weak thermopile, bad switch or wiring | Test and replace the failed part |
| Remote does nothing | Dead batteries in remote or receiver | Replace batteries, re-pair the remote |
| Small, weak or yellow flame | Dirty burner, logs out of place | Clean burner, set the logs right |
| Pilot will not light at all | Gas valve off, clogged pilot tube | Check the valve, clean the pilot |
Quick Checks Before You Call
You can try these safely before booking a gas fireplace repair:
- Make sure the gas valve near the fireplace is open (handle in line with the pipe).
- Replace the batteries in the remote, the receiver and the igniter.
- Check that the wall switch is on and the breaker has not tripped.
- Follow the lighting steps on the label inside the lower panel, exactly as written.
- If it still will not light, turn the valve off and call us. Do not keep trying to light it.
Gas Fireplace Parts We Repair
Most gas fireplace repairs come down to one of the parts below. We test before we replace, so you only pay for the part that failed.
Pilot Light, Thermocouple and Thermopile Repair
The pilot is the small flame that lights the main burner. Next to it sits a thermocouple, a safety sensor that tells the gas valve the pilot is lit. If the thermocouple gets dirty or wears out, the valve shuts the gas off and the pilot goes out.
Many gas fireplaces also have a thermopile. It turns pilot heat into a small electric charge that opens the valve when you flip the switch. A weak thermopile is a top reason a fireplace will not turn on even though the pilot is burning. We clean the pilot assembly, test both parts with a meter, and replace them when they read low.
Igniter and Electronic Ignition Repair
Newer gas fireplaces use an electronic igniter or a control module instead of a standing pilot. When the igniter clicks but nothing lights, the spark gap may be off or the pilot tube clogged. When nothing clicks at all, the battery, module or wiring is often the problem. We test each one and replace only what failed.
Gas Starter and Key Valve Repair
Many older Dallas wood fireplaces have a gas starter, a pipe under the grate that lights the wood. It is turned on with a key valve in the floor or wall. Over time the holes in the starter pipe clog with ash and the key valve gets stiff or leaks. We clean or replace the starter pipe and replace worn key valves at the fireplace. Repairs to the gas supply line feeding it are done by a licensed plumber.
Soot on the Glass and Flame Problems
A healthy gas flame is steady and mostly even across the logs. Black soot on the glass, a tall smoky flame or a flame that lifts off the burner means the fuel is not burning cleanly. Common causes are logs set in the wrong spots, burner ports clogged with dust or spider webs, a dirty air shutter or a vent that is not drawing. We clean the burner and pilot, reset the logs to the maker’s diagram and check the vent. Then we clean the glass with a product made for fireplace glass.
Gas Log Installation
Logs that are crumbling, faded or set in the wrong spots can block the flame and cause soot. We reset logs to the maker’s pattern, refurbish worn sets and install new ones. See our gas log installation page for vented and vent-free options.
Gas Fireplace Smells and Carbon Monoxide Safety
A new gas fireplace can smell like hot paint for the first few hours of use. That fades. A rotten-egg smell is different. That is the odor added to natural gas, so leave the house and call Atmos Energy or 911.
A blocked or cracked vent can push carbon monoxide into the room without any smell. The EPA lists leaking chimneys and fireplaces among the indoor sources of carbon monoxide, and notes the CPSC advice: CO alarms on every level and a yearly professional inspection of fuel-burning appliances. We check the vent, the flue and the cap on every gas fireplace repair. A yearly fireplace inspection or chimney sweep also catches nests and blockages.
Signs Your Gas Fireplace Needs Repair
- The pilot will not light or will not stay lit
- The burner lights with a loud pop or a delay
- Black soot on the glass, logs or the front of the unit
- A yellow, lazy or uneven flame
- The fireplace shuts off on its own after a few minutes
- A gas smell, or your CO alarm goes off
