Why Does My Gas Cooker Flame Keep Going Out? Common Causes and Fixes
A gas cooker flame should normally stay steady once the burner is lit. If the flame keeps going out, especially when you turn the heat down, there is usually a reason worth checking.
The cause may be something simple, such as a wet or poorly positioned burner cap. It can also point to an ignition, gas-supply or appliance problem that needs professional attention. Here is what to check safely.
Check the Burner First
A burner that has been cleaned recently may still have moisture around it. A burner cap that is not sitting correctly can also affect the flame. Turn the burner off and let it cool before checking these visible parts.
Keep the burner and cap clean and dry. Do not poke into gas openings with objects or try to enlarge them. If the burner remains difficult to light or keep lit, have it checked.
The Flame May Be Set Too Low
Some cookers can struggle to maintain a flame at an extremely low setting. If the flame disappears only when you turn the control down, the minimum setting or appliance adjustment may need attention.
Do not try to adjust internal gas controls yourself unless the appliance manufacturer specifically provides a safe user procedure. A qualified technician can determine whether the cooker needs adjustment or servicing.
Check the Gas Supply
A weak or unstable flame across several burners may indicate a gas-supply problem rather than one dirty burner. The cylinder, regulator, hose and connections all form part of the supply system.
If you recently changed or refilled the cylinder, make sure the regulator and connection are correctly fitted. Do not force a stiff valve or attempt to repair a damaged regulator yourself.
If you need help with the connection, see our guide on how to safely connect a gas cylinder to your cooker.
A Strong Draught Can Affect the Flame
A strong draught from an open window, fan or nearby ventilation point can disturb a small burner flame. Your kitchen still needs adequate ventilation, so do not block vents or close off required airflow just to keep a flame burning.
Instead, check whether the flame problem changes when ordinary cooking conditions are restored. If the flame continues to go out, stop using the affected burner and have the cooker checked.
Watch for an Abnormal Flame
A healthy LPG flame is generally steady and predominantly blue. Persistent yellow or orange flames, unusual noise, soot or repeated flame failure are signs that the cooker may need attention.
If the flame is yellow or orange, read our guide on why a gas flame can turn yellow instead of blue before continuing to use the cooker.
What to Do If You Smell Gas
If the flame goes out and you smell gas, do not try to relight it immediately. Turn the burner control off. If it is safe to do so, turn off the gas supply, avoid flames and other ignition sources, ventilate the area and seek appropriate help.
Never use a match or lighter to find a leak. If you notice a gas smell, our guide Why Does My Gas Smell? explains the next steps.
When You Should Stop Using the Cooker
Stop using the cooker if the flame repeatedly goes out, the hose or regulator appears damaged, you smell gas, the flame remains abnormal or the appliance behaves in a way you cannot explain.
Repeated flame failure is not something to ignore. A qualified gas-appliance professional can inspect the cooker and determine whether the burner, ignition system, regulator or another part needs attention.
Frequently Asked Questions
Why does my gas flame go out when I release the knob?
Some cookers use a flame-safety device that requires the control to be held briefly after ignition. If the flame goes out every time you release the knob, the safety system or appliance may need inspection.
Why does my gas cooker flame go out when I turn it low?
An extremely low setting, burner problem or appliance adjustment can cause this. If it happens repeatedly, have the cooker checked rather than trying to adjust internal gas controls yourself.
Can wind make a gas cooker flame go out?
Yes. A strong draught can disturb a small flame. Keep the required kitchen ventilation, but avoid placing the cooker where a strong direct draught repeatedly affects the burner.
Is it safe to keep relighting a burner that goes out?
No. If a burner repeatedly goes out, turn the control off and investigate the cause safely. If you smell gas or the problem continues, stop using the cooker and seek professional help.
The Bottom Line
A gas cooker flame that keeps going out should not simply be ignored. Start with safe, visible checks such as the burner cap, moisture and obvious supply issues. If the problem persists, let a qualified professional find the cause.
