Quick answerGas fireplace repair in Spokane usually traces a fireplace that will not light or stay lit to a dirty pilot, a worn thermocouple or thermopile, a failed igniter or remote receiver batteries. A technician tests the millivolt output, cleans the pilot assembly, checks gas pressure and venting, and cleans the glass and logs, most often in one visit.

How gas fireplaces fail
Most residential gas fireplaces and inserts run on a standing pilot or an intermittent pilot with an electronic igniter. The pilot flame heats a thermocouple or thermopile, which produces a small voltage that holds the gas valve open. When the pilot is dirty or the sensor is worn, the voltage drops and the fireplace shuts off, often a few minutes after lighting.
We also check the things that matter for safety: the vent termination outside, the glass gasket, carbon monoxide levels near the unit and the condition of the logs and burner. Sooty glass is usually a sign of a combustion problem, not just dirt.
Gas fireplace repairs we do
Pilot and igniter won't light
When you hear clicking but no pilot lights, or the pilot lights and goes out, we check the gas supply, the pilot orifice for dust and spider webs, the igniter spark and the wiring. On units with remotes, weak receiver batteries are a surprisingly common cause, and we check them first. We clean the pilot assembly so the flame hits the sensor properly, confirm the gas pressure at the valve, and run the unit through several start cycles before calling it fixed.
Thermocouple and thermopile replacement
The thermocouple proves the pilot is lit; the thermopile generates the power that runs the main valve on many millivolt fireplaces. Both wear out over years of heating. We measure their output with a meter under the manufacturer's test conditions, and replace whichever reads low with the correct part for the model. A fireplace that lights and then shuts off after a few minutes, or one where the main burner will not come on even though the pilot is lit, very often has a weak thermopile.
Annual gas fireplace cleaning
Once a year, we remove the glass, clean it with a fireplace-specific cleaner, inspect the gasket, and vacuum the firebox, burner and log set. We rearrange the logs to the manufacturer's diagram, because logs moved out of place cause flame impingement and sooting. We clean the pilot assembly, test the safety system, check the vent termination outside for blockage and verify the carbon monoxide reading near the unit. You get a note of anything worn, such as a gasket or thermopile, before it fails mid-winter.

Fireplace season in Spokane
Spokane homes lean on their gas fireplaces through a long, cold heating season, and many are used most on the coldest evenings, when a failure is least welcome. A unit that sat all summer collects dust and spider webs in the pilot, which is why the first cold week of fall brings a wave of fireplaces that click but will not stay lit. A cleaning before the season avoids most of those calls.
What you can check first
| Safe to check | Call us | |
|---|---|---|
| Remote and wall switch | Replace batteries in the remote and receiver | If it still will not respond |
| Gas valve | Confirm the fireplace shutoff is open | If gas is on but nothing lights |
| Glass | Wipe light haze when cool | Black soot or cracked glass |
| Gas smell | Leave and call the gas utility | After the utility clears it |

Gas fireplace questions
Why does my gas fireplace turn off after a few minutes?
Usually a weak thermopile or a dirty pilot that no longer heats the sensor properly.
Is black soot on the glass dangerous?
It points to a combustion problem. Have it checked before using the fireplace more.
How often should a gas fireplace be serviced?
Once a year, ideally before the heating season.
Can I leave the pilot on all summer?
You can, but turning it off saves gas on standing-pilot units. We show you how to relight it.
Do you service gas inserts in wood fireplaces?
Yes, along with built-in gas fireplaces and freestanding gas stoves.
