Quick Answer
A gas cooktop igniter that clicks repeatedly without lighting is usually caused by one of five faults: a dirty or food-clogged igniter, a wet igniter after cleaning, a faulty igniter switch or module, a burner cap sitting incorrectly, or a gas supply issue. If you also smell gas, stop and treat it as a safety issue, not a troubleshooting one.
If you smell gas at any point — whether the igniter is clicking or not — turn off the cooktop's gas supply at the isolation valve, ventilate the area, and call a licensed gas fitter immediately. Do not attempt to keep lighting the burner.
A clicking igniter with no flame is one of the most common cooktop calls Melbourne technicians receive, and in a genuine majority of cases it's a simple, safe fix rather than a serious fault. The key is knowing which of the common causes applies, and recognising the small number of situations where it's a safety issue rather than a maintenance one.
Here's what usually causes it, and where the line sits between a homeowner-safe check and a job for a licensed cooktop repair technician.
The Most Common Cause: A Dirty or Wet Igniter
The igniter creates a small spark, and it needs a clear, dry gap to do so reliably. Food spills, grease, or moisture from recent cleaning are by far the most common reason a burner clicks but doesn't light — and it's also the easiest to fix yourself. If the cooktop was cleaned recently and this started right after, moisture is the most likely cause and often resolves within an hour of air-drying.
- Wipe the igniter electrode (the small spark point near the burner) dry and free of food debris
- Make sure the burner cap and base are correctly seated and aligned — a misaligned cap is a very common, easily missed cause
- Wait 15–30 minutes after cleaning before assuming a fault, in case moisture is still drying out
When It's the Switch or Module, Not the Igniter Itself
If the igniter is clean, dry, and the burner cap is correctly seated but the clicking still doesn't produce a flame — or the clicking sound itself is weak or intermittent — the fault is more likely in the ignition switch or the cooktop's ignition module rather than the physical spark point. This is common on cooktops several years old and isn't something to keep testing repeatedly, since prolonged clicking without ignition allows unburned gas to accumulate.
When It's a Gas Supply Issue
If every burner on the cooktop is affected at once, rather than just one, the cause is more likely upstream of the igniter altogether — a partially closed isolation valve, a supply line issue, or (for LPG) a low or empty bottle. A single burner affected on its own points more toward that specific burner's igniter, cap or injector rather than the gas supply. For general warning signs of a gas leak specifically, see our guide on gas cooktop leak signs.
The Safety Line: When to Stop and Call a Technician
Repeated clicking without ignition — more than roughly 10–15 seconds of continuous attempts — should be stopped rather than persisted with, because it allows gas to build up around the burner before it eventually lights, which can cause a small flare when it finally does. This is the point to turn the knob off, wait a minute for any gas to disperse, and either try once more briefly or call a technician if it recurs. Any smell of gas overrides every other step in this guide.
What's Safe to Check Yourself vs When to Call a Pro
Safe to Check Yourself
- Wipe the igniter electrode dry and clear of food debris
- Check the burner cap is correctly seated and aligned in its base
- Confirm the issue affects one burner (points to that burner) versus all burners (points to gas supply)
- For LPG cooktops, check the bottle isn't empty or very low
- Never attempt more than a few short lighting attempts in a row — turn off and pause if it doesn't light quickly
Always Call a Licensed Technician
- Diagnosing and replacing a faulty ignition switch or module
- Any work involving the gas supply line, isolation valve or regulator
- Replacing a damaged burner head, cap or injector
- Full safety inspection where a gas smell has been present
Frequently Asked Questions
Is it dangerous if my cooktop clicks but doesn't light?▼
A brief click-and-fail is usually just a maintenance issue, not dangerous. It becomes a safety concern if you keep trying repeatedly for an extended period (allowing gas to build up) or if you smell gas at any point — in either case, stop and call a licensed technician.
Why does only one burner click without lighting while the others work fine?▼
This points to something specific to that burner — most often a dirty or misaligned igniter or cap on that burner alone — rather than a gas supply issue, since a supply problem would typically affect all burners.
Can I clean the igniter myself?▼
Yes — wiping the igniter electrode dry and clear of debris with the cooktop off and cooled is a standard, safe homeowner task and resolves a large share of clicking-but-not-lighting cases.
How much does it cost to fix a cooktop igniter fault in Melbourne?▼
A switch or module replacement typically falls between $150 and $320 depending on the cooktop brand and model. We provide a fixed quote before any work begins.
What should I do if I smell gas near my cooktop?▼
Turn off the cooktop's gas supply at the isolation valve, open windows to ventilate, don't operate any electrical switches nearby, and call a licensed gas fitter immediately. Don't attempt to keep lighting the burner or diagnose the cause yourself.
