Why a Gas Burner Clicks but Does Not Light
The click and the flame are two different jobs.
When you turn a burner knob, the range does two things: it opens the gas valve and it sends sparks to an igniter near the burner. The clicking you hear is the spark. For a flame, gas must reach the burner and the spark must be able to light it.
If the gas path is blocked or the spark is weak, you hear clicking with no flame. If gas flows but nothing lights, the smell of gas can build, which is why it is important not to let a burner click for long.
Most of the time, the cause is simple: food or grease blocking the ports, or the burner cap sitting wrongly.
If you smell gas, do not keep trying to light the burner. Leave the home and see our guide on a gas smell from a stove.
Common Causes of a Gas Burner Not Lighting
From the easiest to check to those that need a technician.
Dirty burner ports
Spills and grease clog the small holes where the flame forms.
Burner cap not seated
A cap that is crooked or on the wrong burner can block gas or the spark.
A wet burner
After cleaning or a boil over, water can block the ports and stop lighting.
A dirty or damaged igniter
A coating of grease on the electrode weakens the spark.
A weak or failed spark module
The module that creates the spark may fail, so one or all burners will not light.
A faulty burner switch
The switch behind the knob may not send the spark signal.
A gas supply issue
A closed shutoff valve or a regulator problem may restrict gas. Do not investigate yourself.
A worn burner base
Heat and age can warp the base so the cap does not seat.
How to Fix a Gas Burner That Will Not Light: Six Safe Steps
All of these are done with the burners off and cool. If you smell gas at any point, stop and leave.
Turn everything off and let it cool
Make sure all knobs are off and the grates are cool.
Lift the grate and the cap
Remove the burner cap and look for food or grease. Wash the cap with soapy water and dry it fully.
Clean the ports
Use a straight pin or needle to clear the small holes in the burner head. Do not enlarge them.
Clean the igniter
Wipe the small ceramic electrode near the burner with a damp cloth, then dry it.
Reseat the cap
Place the cap so it sits flat and level. Check that it is on the right burner.
Test the burner
Turn the knob to light. If it clicks and lights within a few seconds, you are done. If it only clicks, turn it off.
Have ready
- A soft brush or old toothbrush
- A straight pin or needle
- A damp cloth
- A towel to dry parts

Burner Not Lighting FAQs: Quick Answers Before You Call
Short answers to the questions we hear most. If yours is missing, call and ask.
Why does my gas burner click but not light?
Dirty ports, a misaligned cap, a dirty or weak igniter, or a spark module issue are the usual causes.
How do I clean a gas burner?
With the burner off and cool, remove the cap, clear the ports with a pin, wipe the igniter, dry everything, and reseat the cap.
Is it safe to keep clicking the burner?
Not for long. If it does not light in a few seconds, turn it off. A smell of gas means leave and call from outside.
Why are all my burners not lighting?
A gas supply issue or a spark module fault is more likely than a dirty burner. This needs a technician.
Can a wet burner stop lighting?
Yes. Water in the ports can block the flame. Let it dry fully.
