Gas Fireplace Ignition Repair
Fireplace clicks but won't light? We diagnose and fix ignition failures — same-day service available.
Ignition System Components We Service
Gas fireplace ignition is a sequence — multiple components that have to work in order. A failure anywhere along that chain stops the whole thing. We diagnose and repair all of it.
Igniter Module & Spark Electrode
The igniter module generates the high-voltage spark, and the electrode is the physical tip that delivers it to the gas stream. Over time, electrodes develop hairline cracks, pick up carbon buildup, or drift out of the correct gap position — any of which can stop the spark from jumping reliably. That's the classic "clicking but no flame" call: you can hear the igniter working, but nothing lights because the spark isn't reaching the gas where it needs to.
Gas Valve & Solenoid
The gas valve controls fuel flow to the pilot and the main burner, with an internal solenoid that opens and closes based on signals from the control board. Solenoids fail mechanically, or the valve stops responding when it's getting a weak or missing voltage signal from something upstream. When the valve won't open, no gas reaches the burner — doesn't matter how good the igniter and electrode are. Valve diagnosis requires electrical testing, not just a look-see.
Control Board / IFC Module
The IFC board runs the whole show — it signals the valve to open, fires the igniter, monitors the flame sensor, and triggers safety lockouts when something doesn't complete right. Power surges, moisture, and plain old age can take out a board, and when that happens the symptoms can look like almost anything: no response at all, intermittent ignition, or a system locked out that won't reset. A lot of IFC boards store fault codes that tell us exactly which step in the sequence broke down, which speeds up diagnosis considerably.
Remote Control Receiver
The remote receiver sits between your wall switch or handheld remote and the control board, translating your input into something the fireplace can act on. Receivers fail from age, RF interference, or dead batteries in the remote — and when they do, no ignition command ever makes it to the hardware, even if the board, valve, and igniter are all working perfectly. It's one of the most overlooked failure points, because the fireplace looks fine and the problem is entirely in the signal path. We check it early.
How We Troubleshoot Ignition Failures
We don't start by swapping parts. We trace the full control chain from the switch to the flame — that way we know exactly what failed before we touch anything.
- 1Switch and power input — We confirm the wall switch or thermostat is sending a signal and that the receiver module is picking it up. This rules out control-side failures before we dig any deeper.
- 2Receiver and control board — We test the receiver output and pull any fault codes or lockout conditions stored on the IFC board. A lot of boards log exactly which step in the sequence failed and when, which saves a lot of guesswork.
- 3Gas valve signal and response — We verify the board is sending the right voltage to the valve solenoid and confirm the valve is actually opening. If it's getting a good signal but still won't open, that points to an internal valve failure.
- 4Igniter and electrode — We check the spark electrode for cracks, carbon tracking, or misalignment, and verify the igniter module is producing adequate voltage. If everything upstream checks out, this is the last place to look.
IPI vs. Millivolt vs. Standing Pilot — What You Have Matters
Gas fireplaces use three fundamentally different ignition approaches, and knowing which one you have matters a lot. The symptoms of a failed ignition can look identical on the surface — but the diagnosis and repair are completely different underneath.
Standing Pilot
A small pilot flame burns all the time, kept alive by a thermocouple that holds the gas valve open. Simple, mechanical design — very few electronic parts. The main failure points are the thermocouple, thermopile, and pilot orifice, and all of them are testable with a multimeter and replaceable in one visit. You can relight it manually when it goes out.
Millivolt System
The standing pilot heats a thermopile, which generates the millivoltage that runs the gas valve and the whole control system — no external power needed. Common in units from the '90s and early 2000s. When the thermopile output degrades, the valve loses power and the fireplace stops working. Output is easy to test with a multimeter, and replacement is straightforward.
Intermittent Pilot Ignition (IPI)
A circuit board fires a spark igniter on demand to light the pilot only when you want heat. More efficient than a standing pilot — no continuous gas use. But when the board, igniter, or flame sensor goes, you get nothing and there's no manual relight option. Diagnosis means tracing the full electronic control sequence from input to flame.

Frequently Asked Questions
Why won't my gas fireplace ignite?
Could be a faulty igniter module, a control board in safety lockout, a gas valve that won't open, dead batteries in the remote, or a pilot assembly that needs cleaning. The frustrating part is that several different failures can produce the same "nothing happens" symptom. That's why testing matters — the fix depends entirely on which link in the chain actually broke. Replacing parts without testing first is how you end up spending money on components that weren't the problem. We test before we replace anything.
My fireplace sparks but won't light — what's wrong?
Clicking with no flame means the igniter is doing its job — the problem is on the gas side or the signal side. Gas isn't reaching the burner, or it's getting there but not igniting. That usually points to a gas valve issue, a blocked pilot or burner orifice, or an overheat sensor that's tripped the system into safety lockout. It can also mean the pilot flame isn't establishing at all, which prevents the valve from opening to the main burner even with a good spark. We trace the gas path and control signals together rather than just guessing at the most likely part.
Can a remote control cause ignition failure?
Yes — and it's one of the first things we check. Dead batteries, a failed receiver module, or a faulty wall switch can all kill ignition even when the fireplace hardware is perfectly fine. The receiver sits between your input and the control board; if the signal never gets through, the board never starts the ignition sequence. We always start from the control side rather than heading straight to the fireplace components, because skipping that step wastes time and leads to replacing parts that were never the issue.
Is ignition repair covered under warranty?
It depends on your unit's age and what the manufacturer's warranty actually covers. Some components — control boards and gas valves in particular — carry multi-year warranties on certain brands; others don't. Coverage also varies depending on whether the failure counts as a manufacturing defect or normal wear. We document every repair with the parts replaced, root cause, and date of service in case you need to file a claim. If you think your unit might still be under warranty, mention it before we start and we'll keep that in mind.
How quickly can you get to me for an ignition repair?
We usually have same-day or next-day availability throughout King, Pierce, and Snohomish counties. Call or text and we'll give you a realistic arrival window — we don't book repair calls out weeks. We also stock common ignition parts on the truck, so if it turns out to be a standard component swap, we can typically finish the job the same day we diagnose it.
My fireplace worked fine last year — why won't it ignite now?
Things break down between seasons even when the fireplace isn't being used. Igniter tips oxidize over the summer, thermopile voltage drops gradually with age, and spider webs or debris blocking the pilot orifice is extremely common in units that sit unused for months — sometimes that's the entire problem. Control boards are also vulnerable to power surges while the fireplace is off, so a board that was fine in the spring might not come back to life in the fall. Honestly, seasonal first-use calls are among the most common we handle. We're not surprised by them.
