Pilot Light Repair Seattle, WA

Pilot light repair is the fix for one specific, very common gas fireplace complaint: the little standing flame at the burner either will not light at all, lights but dies the moment you let go of the knob, or stays lit for a while and then quits on its own. Almost every time, the cause is one of a short list of parts: a worn thermocouple or thermopile, a pilot orifice clogged with dust or spider webbing, a weak or drifting flame, or a draft that keeps blowing the pilot off its sensor. Our technicians diagnose which one it is and correct it.

This page is for homeowners whose fireplace has a pilot problem and little else. If the pilot lights and holds fine but the main burner is the trouble, that is the territory of our Gas Fireplace Repair service, which covers burners, switches, remotes, blowers and valve assemblies as a whole. If the unit has never been serviced and is simply coated in soot and dust, our Gas Fireplace Cleaning service may be the right first step. Pilot Light Repair is narrower and faster: we isolate the pilot system, test its components, and get it holding a steady, correct flame again.

One note before anything else: if you smell gas anywhere in the house, stop, leave the home, and call your gas utility or 911 from outside. Do not try to relight a pilot in that situation. Gas lines and valves are only serviced by a qualified technician.

Timing & Safety

When Pilot Light Repair Is Necessary vs. Optional

Call for repair when:

• The pilot drops out repeatedly during the season, even though it lights fine at first.
• The pilot is lit but the main burner will not respond to the switch, remote or thermostat.
• The pilot flame is yellow, sooty, or noticeably smaller than it used to be.
• The igniter clicks but never produces a spark.

Probably optional or not needed when:

• The pilot was turned off for the summer and relit without trouble using the steps on the unit. That is normal, not a fault.
• A single outage happened during a windstorm or when a window was open, and the pilot has held since.
• The whole fireplace is dirty and has not been serviced in years. In that case an annual Gas Fireplace Cleaning often resolves a sluggish pilot as part of the service.

Most manufacturers print relight instructions on a plate inside the lower control compartment. Following those steps exactly, including the waiting period after any gas smell clears, is reasonable for a homeowner. What is not reasonable is bending sensors, disassembling the pilot, or working on any gas line or valve. That is where a technician takes over.

Safety considerations

Gas appliances are safe when their safety systems work, and the pilot system is one of those safety systems. The thermocouple or thermopile exists so the valve cannot open unless a flame is present. A pilot that will not hold is the appliance doing its job; the fix is to repair the part, never to defeat it.

• If you smell gas, leave the house immediately and call your gas utility or 911 from outside. Do not light anything, flip switches, or try to relight the pilot.
• Follow only the relight steps printed on your fireplace. If the pilot does not light after the manufacturer's stated attempts, stop and call us.
• Never hold the pilot knob down with tape, a clamp or any other object to keep the flame on. Doing so removes the only safeguard against unburned gas.
• Gas lines, shutoffs and valves are serviced only by a qualified technician. Our Gas Valve Repair service handles those separately.
• Keep working carbon monoxide alarms on every level of the home and near sleeping areas.
• NFPA 211 recommends an annual inspection of fireplaces and venting; a pilot fault is a good reason to have the rest of the system looked at too.

Seattle & Puget Sound conditions

Pilot problems in the Seattle area have a seasonal rhythm. Most homeowners shut the pilot off in spring and do not touch the fireplace until the first damp, cold evening in October or November. Over those months, dust settles on the pilot hood, and spiders, which are drawn to the odorant in natural gas, are a well-known cause of plugged pilot orifices in Puget Sound homes. So the first relight of the season is when we get the most calls. Our long, wet heating season also means the fireplace runs for many more hours than in drier climates, which wears out thermocouples and thermopiles faster. Direct-vent units on windward walls in Tacoma, West Seattle, Everett and along the Sound see strong gusts pushing back through the vent termination, which can blow out a pilot that is already marginal. Older homes in King and Pierce counties with decades-old standing-pilot inserts are the most common case of a tired thermopile that holds the pilot but cannot open the main valve.
