A gas burner that clicks endlessly without lighting is one of the more irritating kitchen problems — especially when you’re in the middle of cooking. But there’s a meaningful difference between “this burner is dirty” and “this stove has a gas problem.” One of those you fix with a paper clip. The other you stop using and call for help.
At Yanfix, gas stove ignition calls are some of the most common range repair requests we see in Ottawa. Six causes cover the vast majority of cases. Most of them are simple enough to diagnose yourself. A couple require a technician, and one of them — the smell of gas — needs immediate attention regardless of what else is going on.
Here’s how to work through the six causes in order, know what’s safe to handle yourself, and recognize when the stove should stay off.
Don’t wait for the problem to get worse — our trained technicians are ready to help today. We offer same-day appliance repair, transparent pricing, and a 90-day warranty on all work.
Before anything else: when to stop and call immediately
If you smell gas when the burner is off, stop everything. Don’t try to light anything. Don’t use any electrical switches. Open windows and doors, leave the house, and call your gas utility from outside. A persistent gas smell with no obvious source is a gas supply or valve issue and it needs emergency service, not DIY troubleshooting.
If the burner produces a yellow or orange flame instead of blue, or if there’s a sulphur-like smell only when the burner is lit, those are signs of incomplete combustion. The burner may need cleaning, but if cleaning doesn’t resolve it, a technician should check the gas-air mixture.
Everything below assumes the stove is not actively leaking gas. If there’s any doubt about that, the stove stays off until someone has looked at it.
The six most common reasons a gas burner won’t ignite
1. Food debris around the igniter or burner cap
This is the most common cause by a wide margin. The spark igniter sits at the base of each burner, and the burner cap sits directly above it. When cooking liquid boils over or food falls into the burner area, it can coat the igniter in grease or block the burner cap ports that the gas flows through. The igniter sparks, but either the gas can’t reach the flame, or the spark can’t cross the gap properly.
The fix: remove the burner grate, lift off the burner cap, and clean both the cap and the igniter with a dry toothbrush or a straightened paper clip. The burner cap ports are the small holes around the rim — make sure each one is clear. Dry everything completely before reassembling. Even a little moisture on the igniter causes it to keep clicking after you’ve lit the other burners.
2. Wet igniter
A wet igniter clicks continuously across all burners, not just the one you’re trying to use. This usually happens after a spill, a cleaning session with too much water, or in a very humid kitchen. The moisture creates a conductive path and the igniter sparks continuously looking for a flame that isn’t there.
The solution is drying time. Wipe the igniter area dry with a cloth, then let the stove air out for an hour. Running the stove on the lowest heat setting for a few minutes can help drive out moisture faster. If a specific burner keeps clicking after everything is dry, that igniter likely has a crack or internal fault.
3. Misaligned or damaged burner cap
Every burner has a cap that has to sit flat and centred on the burner base. If it’s slightly off-centre after cleaning or a spill, gas doesn’t distribute evenly and the burner either doesn’t light or lights unevenly. Some burner caps have a notch that aligns with a pin on the base — if yours does, check that it’s seated correctly.
Lift the cap, look at the base, and reseat the cap carefully. If the cap is warped or cracked from heat, it needs replacing. A damaged cap prevents even gas flow regardless of how the rest of the burner is functioning.
4. Faulty spark igniter
Igniters wear out. A burner that consistently takes many attempts to light, or one that produces a weak or intermittent spark, likely has a failing igniter. You can confirm this by watching the igniter in a dim room while pressing the ignition: a healthy igniter produces a sharp, bright blue spark. A failing one produces a weak orange spark or nothing at all.
Igniter replacement is a straightforward repair on most gas stoves. The component itself is usually inexpensive, and access varies by model — on some, it’s a ten-minute job; on others, you need to remove the stovetop. If multiple igniters are failing at the same time, the igniter switch module is more likely the culprit than the igniters themselves.
5. Clogged gas port or faulty igniter switch
The gas port is a small opening in the burner base that gas flows through before it hits the burner cap. A port that’s completely blocked by baked-on debris can prevent ignition even when the igniter is working. Use a fine needle or a thin piece of wire to clear each port — don’t use a toothpick, as it can break off inside.
The igniter switch is the component behind the knob that triggers the spark. If a burner ignites fine on one attempt but doesn’t respond reliably to the knob, or if the spark starts before the knob reaches the ignition position, the switch is the issue. This is a repair that involves taking apart the control panel and is best left to a technician.
6. Problem with the gas supply or valve
If none of the above applies and no burner on the stove will light, the issue is with the gas supply to the stove itself. The supply valve behind or beneath the stove may have been accidentally turned or may have failed. If you recently moved the stove for cleaning, check that the flexible gas connector isn’t kinked and the valve is fully open (handle parallel to the pipe).
A faulty gas valve inside the stove — the component that controls gas flow to individual burners — can also prevent ignition on one or more burners while leaving others unaffected. These valves can’t be safely cleaned or adjusted by a homeowner and need professional replacement.
Never attempt to repair or bypass a gas supply component yourself. If the supply valve or internal gas valve is suspected, leave the stove off and call a technician.

Quick diagnosis at a glance
What you see / hear | Most likely cause | What to do |
One burner won’t light, others fine | Debris on igniter or blocked cap ports | Clean igniter and burner cap, clear ports |
Clicking continues after burner lights | Moisture on igniter | Dry the igniter area, let air out |
All burners click but none light | Wet igniter module or power issue | Dry thoroughly, check circuit breaker |
Uneven or weak flame after lighting | Clogged cap ports or misaligned cap | Clean ports, reseat cap flat |
Burner lights slowly or inconsistently | Failing igniter or worn switch | Observe spark quality, call technician |
No burner on the stove lights | Gas supply or main valve issue | Check supply valve, call technician |
Smell of gas when burner is off | Gas leak | Leave house, call gas utility immediately |

What you can safely check yourself
- Turn off all burners and wait for the stove to cool completely.
- Remove the burner grates and lift off each burner cap.
- Inspect each igniter: it should be clean, dry, and white or cream-coloured. Anything coated in grease or discoloured needs cleaning.
- Use a dry toothbrush to clean debris from around each igniter. For stubborn buildup, use a paper clip or thin wire. Don’t use water directly on the igniter.
- Check the burner cap ports with a needle. Each small hole around the rim should be fully open.
- Reseat all burner caps flat and centred.
- Wipe down the entire burner area and let it dry completely before testing.
- Test each burner one at a time. A healthy ignition produces a flame within one or two clicks.
If cleaning doesn’t resolve it, the next step is watching the igniter spark in a dark kitchen. Weak, orange, or absent sparks mean the igniter has failed. Reliable sparks with no ignition usually point to a gas flow problem.

When to stop troubleshooting and call a technician
There are clear lines between what’s safe to handle yourself and what isn’t.
Call a technician if the igniter produces a good spark but the burner still doesn’t light after cleaning. That means gas isn’t reaching the burner, which is a valve or supply issue.
Call a technician if you need to access the igniter switch behind the control knob. This involves removing the control panel and working near gas connections.
Call a technician if multiple igniters fail around the same time. This usually points to the igniter module or the wiring, not the individual igniters.
Call a technician — or your gas utility first — any time you smell gas with the stove off. That’s not a cleaning problem.

How to avoid ignition problems in the first place
Most gas stove ignition problems are preventable. They’re almost always caused by boilovers that sit on the burner area long enough to bake onto the igniter and cap.
Clean spills quickly. A boilover that gets wiped up within a few minutes won’t cause problems. One that gets left and then cooked onto the burner area over the next few days will.
When you clean the stovetop, remove the burner caps and wipe them separately. The ports around the rim are small enough that buildup blocks them faster than it looks. A monthly wipe of the caps and a once-a-month check of the ports with a needle is enough for most households.
Let burner components dry completely after any wet cleaning. Water on an igniter causes the clicking issue described above, and it also accelerates corrosion on the igniter tip over time.
If a burner ever produces a yellow or orange flame instead of blue, clean the cap and ports before the next use. That colour means incomplete combustion, usually from blocked ports affecting the gas-air ratio.
Brand-specific notes for Ottawa homeowners
Brand | Common ignition issue |
Samsung | Igniter switches wear faster on slide-in models; control panel access required for replacement |
LG | Burner cap alignment is critical — small off-centre seating prevents ignition on ProBake models |
Whirlpool / Maytag | Igniter module failures tend to affect all burners simultaneously |
Bosch | Sealed burner caps are less prone to port blockage but harder to remove for cleaning |
GE / GE Cafe | Dual-ring burners have two sets of ports — both rings need cleaning when one fails |
Frigidaire | Igniter tip corrosion is more common; inspect tip condition when cleaning |

FAQ
Q: Why does my gas stove keep clicking even after the burner is lit?
Continuous clicking after ignition almost always means moisture on or around the igniter. A spill, a cleaning session that got water near the igniter, or even a very humid day can cause it. Dry the igniter area thoroughly with a cloth and let the stove air out. If one specific burner keeps clicking after everything is dry, that igniter may have a crack and needs replacing.
Q: My burner clicks and sparks but the gas won’t light. What’s wrong?
A good spark with no ignition means gas isn’t reaching the burner. The most likely causes in order: blocked burner cap ports (clean them with a needle), a misaligned burner cap (reseat it flat), or a gas supply issue. If the cap is clean and properly seated and the burner still won’t light, the gas valve or supply needs professional diagnosis.
Q: Can I use the oven if a stovetop burner won’t ignite?
Usually yes, since the oven and stovetop use separate ignition systems on most ranges. But if the problem is with the gas supply to the stove rather than an individual burner igniter, neither the stovetop nor the oven will work reliably. If you smell gas or multiple burners are affected, leave the whole stove off until it’s been checked.
Q: My gas stove burner ignites but the flame is uneven or weak. Is that an ignition problem?
An uneven flame is a gas flow problem, not an ignition problem. The burner cap ports are likely partially blocked, disrupting the gas-air mix. Remove the cap and clear each port with a needle. If the flame is consistently low across all burners, the gas supply pressure may be the issue, which needs a technician to check.
Q: How much does gas stove repair cost in Ottawa?
Igniter replacement typically runs $100-200 depending on the brand and how accessible the component is. Igniter module or switch replacement is usually $150-300. Gas valve work varies more and depends on the model. Yanfix provides an upfront price before any work begins, so there are no surprises. Call or book online for a same-day diagnosis.
Bottom line
Most gas burner ignition problems start with debris on the igniter or a blocked burner cap. Clean those first, dry everything completely, and test again. That resolves the majority of cases without any parts or service calls.
If the igniter sparks reliably but the burner still won’t light, the problem is with gas flow and needs a technician. And if you’re smelling gas when the stove is off, that’s the one situation where troubleshooting is the wrong move — leave the house and call your gas utility.
