A pot boils over, water floods the burner cap, and suddenly the igniter clicks endlessly without producing a flame. That scenario accounts for the majority of “gas stove igniter won’t light” calls SureFit receives across Barrie, Newmarket, and Collingwood — and it is almost always a DIY-resolvable situation. The minority of cases involving cracked igniter ceramics, failed spark modules, or suspected gas supply problems require a technician. Knowing which situation you are in before touching anything is what this guide is for.

Why a Gas Stove Igniter Won’t Light — 6 Root Causes
Gas range ignition systems are intentionally simple: a spark module generates a high-voltage pulse, a ceramic igniter tip converts it to a visible spark, and the spark ignites gas flowing from the burner. Six failure modes interrupt this sequence.
1. Wet or Dirty Igniter Tip
The most common cause by a wide margin. Food boilovers, steam, and cleaning moisture saturate the ceramic igniter tip. The ceramic, which must be dry and clean to channel the spark correctly, conducts the electricity sideways instead of producing a visible arc. The stove clicks, but no spark reaches the gas. This resolves completely with cleaning and drying.
2. Cracked Igniter Ceramic
The ceramic insulator around the igniter tip can crack from physical impact (dropping a cast iron pan on the grate) or from thermal shock (cold water on a hot burner). A cracked ceramic bleeds the electrical spark to ground before it reaches the tip. Visual inspection under good lighting reveals hairline cracks; replacement of the ceramic igniter tip assembly is required.
3. Faulty Spark Module
The spark module is the electronic control board that generates the high-voltage ignition pulse and routes it to the correct burner’s igniter. When the module fails, one or all burners stop sparking. On most Samsung and LG gas ranges, the module is behind the control fascia. On Bosch ranges, accessing the module requires removing the entire rear panel — a more labour-intensive repair that accounts for Bosch’s higher igniter repair cost.
4. Burner Cap Misalignment
Every gas burner has a cap that must sit precisely centred over the burner base. When this cap is off by even a few millimetres — from cleaning, from being bumped, or from warping under sustained high heat — the gas ports do not align with the igniter tip’s spark path. The result is a spark that fires into open air rather than into the gas stream. Reseating the burner cap solves this in seconds.
5. Control Switch Failure
The igniter switch embedded in each burner’s control knob assembly sends the signal to the spark module when the knob is turned to the ignite position. When this switch fails, turning the knob produces no click at all — silence rather than continuous clicking. Switch failure is a part-and-labour repair; on most ranges the switch is brand-specific and costs $30–$70 + HST per burner position.
6. Gas Supply Issue
If the igniter sparks visibly but no flame appears and there is no smell of gas, the gas supply to that burner may be blocked. A blocked burner orifice (mineral or grease deposit), a closed gas shutoff valve, or a low-pressure supply from Enbridge Gas can all produce this symptom. Gas supply diagnostics beyond confirming the shutoff valve is open must be performed by a TSSA-licensed gas technician.
The Clicking Igniter — What That Sound Means
An igniter that clicks continuously without producing a flame is startling, but it is not inherently dangerous. The clicking means the spark module is functioning and sending pulses to the igniter — the problem is that the spark is not reaching the gas or the gas is not reaching the spark.
Continuous Clicking: Moisture or Misaligned Cap
Continuous clicking after a boilover almost always means moisture in the igniter assembly. The ceramic tip’s resistance has dropped enough that the spark module detects a completed circuit and keeps firing. In some cases the module gets stuck in a continuous-click loop even after the moisture dries — the fix is to turn the affected burner knob past ignition and back to off, which resets the module’s sensing circuit on most designs.
Gas Smell + Clicking: Evacuate Immediately
If you hear or smell gas AND the igniter is clicking, leave the house immediately. Do not operate any electrical switches, do not use your phone inside the building, and do not attempt to find the source. Call Enbridge Gas emergency line from outside: 1-877-969-0999 (24 hours, 7 days). Enbridge’s emergency response is free and they will dispatch a technician to confirm the leak is resolved before re-entering is safe. This is not a SureFit call — it is an Enbridge call first.
No Click at All: Switch or Module
If turning the burner knob produces complete silence — no click, no spark — the problem is upstream of the igniter tip: either the igniter switch in the knob assembly or the spark module itself. This is a diagnosis-and-replace scenario that does not involve any gas safety risk, but does require disassembly of the control panel.
TSSA Rules for Gas Stove Repair in Ontario
Ontario’s Technical Standards and Safety Authority (TSSA) regulates who may legally perform what types of gas appliance work. Understanding this framework protects you legally and ensures the work is performed safely.
What Requires a TSSA Licence
Under Ontario Regulation 212/01 (the Gas Distribution Act’s technical standards), any work involving a gas line, gas valve, gas orifice, or the gas supply connection to an appliance requires a TSSA-licensed gas technician. This includes: replacing a burner orifice, replacing the gas valve assembly inside the range, reconnecting a gas supply line, and converting a range from natural gas to propane (which changes orifice sizing). TSSA licences are issued at the G1, G2, and G3 levels — a G2 licence covers residential gas appliance work. Verify a contractor’s TSSA licence at TSSA.org before authorising any gas-side work.
What Does NOT Require a TSSA Licence
Electrical components on gas ranges — including igniter tips, ceramic igniters, spark modules, igniter switches, control boards, and oven igniters — are not gas components. Replacing these parts does not involve gas lines, gas valves, or gas pressure, and does not require TSSA certification. These are standard electrical appliance repairs. Similarly, cleaning burner caps, reseating burner components, and replacing knobs are maintenance tasks with no licensing requirement.
The Practical Line for Ontario Homeowners
If the repair involves touching anything through which gas flows, a TSSA licence is required. If the repair involves only the electrical spark generation and delivery system, no TSSA licence is required. SureFit technicians handle all electrical ignition repairs; for gas-side work, we can refer you to a TSSA-licensed gas fitter in your area.
Safe DIY Fixes for a Gas Stove Igniter
The following repairs are safe for homeowners to attempt without any special tools or certifications. In all cases, ensure the burner knobs are in the OFF position before starting.
Step 1: Turn Off the Burner (Not the Gas Main)
Turn the affected burner knob to OFF. You do not need to shut off the gas supply at the main for igniter cleaning — the knob in the OFF position closes the gas flow to that burner completely. Never use water for igniter cleaning, as this worsens moisture-related clicking problems.
Step 2: Clean the Igniter Tip
Use a dry toothbrush or stiff-bristle cleaning brush to remove food debris and residue from around the igniter tip and ceramic insulator. For stubborn deposits, dampen a cotton swab with isopropyl alcohol (70% or higher) and clean the ceramic surface. Allow the igniter to dry completely — at least 30 minutes at room temperature, or use a hair dryer on low heat held 15 cm away for 5 minutes.
Step 3: Reseat the Burner Cap
Lift the burner cap off and set it aside. Inspect the burner base for food debris in the gas ports — a toothpick or wooden skewer clears blocked ports safely without risk of damaging the orifice. Replace the burner cap and confirm it sits flat and centred, with no rocking motion. The cap’s alignment notch (present on most Samsung, LG, and Bosch ranges) must engage with the corresponding pin on the burner base.
Step 4: Test the Burner
Turn the burner knob to ignite. You should hear 1–3 clicks and see a flame. If the burner does not light within 4 seconds, turn the knob to OFF and wait 60 seconds before trying again to allow any accumulated gas to dissipate.
Samsung, LG, and Bosch Gas Range Igniter Differences
Each brand designs its ignition system differently, which affects both the failure modes you are likely to encounter and the labour time required for professional repair.
Samsung NX Series Gas Range
Samsung’s NX58 series (sold widely at Best Buy and The Brick in Ontario) uses a sealed burner design with a spark electrode mounted to a ceramic post directly beside each burner. The Samsung spark module is located under the cooktop, accessible after lifting the top panel. Samsung igniter switch failure is common on NX series ranges 5–7 years after installation — the switch part number varies by model year but typically runs $35–$55 + HST. Full igniter system repair on a Samsung NX range: $130–$195 + HST.
LG Gas Range Igniter
LG ranges use a separate igniter switch per burner (part EBF62172804 is the most commonly replaced switch on LG gas ranges in Ontario). Each switch is wired in parallel to a central spark module. LG’s sealed burner system makes burner cap reseating straightforward, but accessing the spark module requires removing the control panel fascia. LG igniter repairs typically run $125–$185 + HST depending on whether one switch or the full module needs replacement.
Bosch Gas Range Igniter
Bosch gas ranges — popular in Barrie and Newmarket high-end kitchen renovations — use an igniter module mounted behind the fascia at the rear of the range. Accessing the module requires removing the entire rear panel assembly, which adds 30–45 minutes of labour compared to Samsung or LG. Bosch igniter module repair runs $175–$250 + HST. The upside: Bosch igniter modules are significantly more durable than Samsung or LG equivalents, with typical service lives of 12–15 years versus 6–10 years.
Ontario-Specific: Propane Conversions in Collingwood and Grey County
Natural gas from Enbridge reaches most of Barrie, Newmarket, Bradford, and Keswick. However, many homes in Collingwood, Owen Sound, the Blue Mountain area, and rural Grey County rely on propane. Gas ranges manufactured for natural gas must be converted for propane use — a conversion that involves replacing the burner orifices with smaller-diameter propane orifices and re-adjusting the gas valve pressure regulator.
Why Orifice Size Matters for Ignition
Propane burns hotter than natural gas and is delivered at higher pressure, requiring smaller orifices. A range converted to propane with the wrong orifice size will either produce yellow-tipped, sooty flames (orifices too large — too much gas) or will be very difficult to light with the igniter (orifices too small — insufficient gas volume at the spark point). Either condition will cause igniter problems that cleaning and component replacement will not fix. Orifice replacement is gas-side work requiring TSSA certification under O. Reg. 212/01.
Identifying a Converted Range
If you purchase a home in Collingwood or Grey County with a gas range, check the conversion sticker — typically applied to the inside of the storage drawer or the back panel. It should list the technician’s TSSA licence number and the conversion date. An unconverted range on a propane line is a safety hazard regardless of whether the igniter is working correctly.
Gas Stove Igniter Repair Cost in Ontario
Understanding the cost breakdown for igniter repairs helps set expectations before a technician arrives and supports the repair-vs.-replace decision.
Ceramic Igniter Tip and Switch
Replacing one igniter tip and the associated igniter switch: $80–$140 + HST for parts and labour. This is the most common repair scenario — a single burner that won’t spark due to a failed switch or cracked ceramic.
Spark Module Replacement
Replacing the central spark module (which affects all burners): $130–$200 + HST. This repair is warranted when multiple burners lose spark simultaneously, which almost always indicates module failure rather than multiple simultaneous switch failures.
TSSA Gas-Side Work
Gas line reconnection, valve replacement, or orifice work starts at $200 + HST and varies significantly based on the scope of work and whether parts are required. Gas-side repairs require a separate TSSA-licensed gas fitter; SureFit handles the electrical ignition components and can refer you to licensed gas fitters in Simcoe County and York Region for gas-side work.
Frequently Asked Questions
Is it safe to light a gas stove burner with a lighter if the igniter isn’t working?
Yes, with one important procedure: turn the burner knob to low or medium and immediately hold a lit long-stem lighter or match at the burner before turning the knob — do not let gas flow for more than 2–3 seconds before attempting to light. The risk with lighting manually is accumulation of unlit gas if you hold the knob open while searching for your lighter. This is a temporary measure only; a non-functioning igniter should be repaired, as manually lighting a burner creates risk each time it is used.
Do I legally need a gas fitter for any gas stove repair in Ontario?
Not for all repairs — only for work involving gas-carrying components. Under Ontario Regulation 212/01, a TSSA-licensed gas technician is required for gas line work, gas valve replacement, burner orifice replacement, and propane conversion. Replacing igniters, spark modules, igniter switches, control boards, and other electrical components does not require TSSA certification. If a contractor claims TSSA licensing is required for an igniter switch replacement, that claim is incorrect — the Ontario gas code does not extend to electrical appliance components.
How long do gas stove igniters typically last?
Ceramic igniter tips last 8–12 years under normal use. Igniter switches — the most commonly replaced component — typically last 6–10 years, with failure accelerated by moisture exposure from frequent boilovers and aggressive cleaning with water. Spark modules last 10–15 years in most cases. In Ontario kitchens where hard-boiling and high-volume cooking is common, or in homes near Georgian Bay where humidity is seasonal, igniter switch life tends toward the lower end of these ranges.
