My gas fireplace won't light in Seattle — what's causing it?

The most common causes are thermocouple or thermopile failure, a fouled pilot assembly, or a faulty igniter. If the pilot lights but the main burner won't stay on, a failing thermocouple is the most likely culprit — it signals the gas valve that the pilot is lit, and a worn-out one interrupts that signal. If the pilot won't light at all, the igniter, pilot orifice, or gas supply needs assessment. Both are typically same-visit fixes.

Should I repair or replace my gas fireplace?

If the unit is under 15 years old and the failure is a component — thermocouple, igniter, valve, remote receiver — repair is almost always the right call. Older inserts in Seattle homes with non-standard masonry venting may need venting corrections regardless of whether you repair or replace. We'll give you an honest read on both paths before you decide.

Is gas fireplace repair something I can DIY?

We strongly advise against it. Gas appliances combine combustible fuel, ignition sources, and ventilation — an improper repair creates gas leak and carbon monoxide risks. In Washington State, gas appliance work should be performed by a licensed technician. It also preserves your warranty and gives you a documented service record.

Can you repair my gas fireplace the same day?

In most cases, yes. We carry common parts — thermocouples, thermopiles, igniters, pilot assemblies, wall switch components, and glass gaskets — on every service vehicle. Most Seattle gas fireplace repair calls are resolved on the first visit. If a specific part needs sourcing, we'll schedule the follow-up promptly.

We serve all Seattle neighborhoods including Queen Anne, Magnolia, Ballard, Capitol Hill, Beacon Hill, Fremont, Wallingford, Phinney Ridge, Montlake, Columbia City, Rainier Valley, and West Seattle — plus Bellevue, Renton, Kirkland, and broader King County.

Common Symptoms That Need a Technician

Seattle gas fireplace problems we diagnose and fix most often

Pilot lights but won't stay on

Usually a failing thermocouple. It senses the pilot flame and holds the gas valve open — when it weakens, the valve shuts off. Thermocouple replacement is one of the most common same-visit repairs we do in Seattle.

Fireplace won't light at all

Could be the igniter, a blocked pilot orifice, or a gas supply issue at the fireplace valve. We test each element in sequence to isolate the fault before doing anything.

Clicks but no flame

The igniter is sparking but not igniting. This points to a gas flow issue at the pilot, a fouled pilot port, or an igniter that's sparking in the wrong position after component wear.

Wall switch or remote stopped working

Wiring faults, dead batteries in the receiver, and failed wall switch relays are common in Seattle homes — especially retrofitted systems. We test the full control chain.

Flame cuts out mid-burn

An intermittent shutoff mid-cycle usually means a thermopile generating insufficient voltage, a flame sensor coated in oxidation, or an overheating shutoff triggered by a blocked blower.

Gas fireplace smells like gas near the unit

Do not operate the fireplace. Leave the room, ventilate, and call. A gas odor near the unit requires immediate professional diagnosis — never a DIY repair.

Repair or Replace? An Honest Guide

We'll give you the same answer we'd give our own family

Repair Makes Sense When…

Unit is under 15 years old and the failure is a single component
Thermocouple, thermopile, igniter, or pilot assembly — parts are inexpensive and long-lasting
Wall switch or remote receiver failed — control system repairs are straightforward
Glass gasket or door seal worn — replacing the seal is simple and cost-effective
Blower or fan motor failed — motors can usually be sourced and swapped same-visit or next visit

Consider Replacement When…

Unit is 20+ years old and multiple components are failing simultaneously
The heat exchanger or firebox is cracked — structural damage is rarely worth repairing in old units
Parts are discontinued and can't be sourced for your model
Older gas insert in a masonry chimney with non-standard venting — replacement may allow proper relining
You want to upgrade to a higher-efficiency model, remote ignition, or thermostat control

We diagnose first, explain what we found in plain language, and give you both options if both apply. No pressure toward the higher-ticket outcome.

Gas Fireplace Brands We Repair in Seattle

We carry parts and have factory training or hands-on experience with all major brands found in Seattle homes. If your unit isn't listed, call — we service most makes.

Napoleon

IFC control board failures, thermopile voltage loss, and pilot assembly wear are the most common Napoleon repairs we see in Seattle. Parts are well-stocked and most repairs are same-visit.

Heat & Glo

SL-550TR and IntelliFire ignition faults are frequent in older Heat & Glo inserts. We also see glass gasket wear on high-cycle units. Remote receiver boards occasionally fail in humid Seattle conditions.

Heatilator

Heatilator units share a parts platform with Heat & Glo — common calls include IntelliFire IPI system faults, blower capacitor failure, and thermocouple replacement after dormant seasons.

Superior

Superior direct-vent inserts installed in Seattle masonry fireplaces sometimes develop venting seal issues that cause draft problems. We check both the unit and the liner connection on every Superior repair call.

Travis Industries

Fireplace Xtrordinair and Lopi units by Travis are reliable but have proprietary control boards. We stock common Travis components and can source less common parts within 1–2 business days.

Valor

Valor's thermostatic systems require specific OEM replacement parts. Pilot assembly and gas valve faults are most common. Valor units in Seattle often sit dormant for months — annual tune-up prevents most failures.

Montigo

Montigo units in Bellevue and Seattle's premium neighborhoods are typically newer direct-vent or see-through designs. Ignition module and valve faults are the most common repair calls.

Regency

Regency gas inserts are common in Eastside Seattle homes from the 2000s. Pilot assembly fouling after dormant seasons and thermopile wear are the most frequent calls.

Majestic

Older Majestic units sometimes have discontinued parts. We assess part availability upfront and give an honest view on repair vs. replacement if parts can't be sourced.

Don't see your brand? Call (206) 339-1919 — we service most residential gas fireplace brands.

How a Gas Fireplace Repair Call Works

Most Seattle repair visits are complete in 1–2 hours

Systematic Diagnosis

We test every element of the system — pilot, igniter, thermocouple or thermopile, gas valve, control board, wall switch, and blower — before drawing a conclusion. We don't guess.

Clear Written Quote

Once we know the cause, we give you a written quote before touching anything. No verbal estimates that change at invoice time.

On-Site Repair

We carry common parts on every vehicle. Thermocouples, thermopiles, igniters, pilot assemblies, wall switch components, and glass gaskets are available immediately in most cases.

Full System Test

After repair, we run the fireplace through a full ignition cycle and verify flame quality, shutoff behavior, control response, and CO levels before signing off.

“I found Genesis through Angi and could not be happier. They came out the next day for a chimney inspection before we started using our fireplace for the season. Technician was thorough, honest, and didn't try to upsell anything unnecessary. Will be booking them every year.”

“Amazing work from Genesis! They came in and worked with my vision to convert one of our fireplaces to gas log and retrofit the other with a gas fire starter. Not only did they take the time to understand exactly what I wanted and make a clear plan, but they even got up on the roof and found a few other critical issues that needed fixing. They handled a long list of items, coordinating and negotiating with other vendors to get everything done quickly and done right — from roof and chimney work to running new gas lines to sweeping. The end result was a custom solution that fit our home perfectly and looks incredible. I can't say enough about the quality of their work, timeliness, and professionalism. Highly recommend!”

David's ability to provide a swift diagnosis went above and beyond my expectations. It's rare to find a service that's both fast and thorough, and Genesis Home Services nailed it. Highly recommend Genesis Home Services to anyone in need.”
