Why Does My Gas Hob Flame Go Out?

Jul 29, 2023, 18:54pm

The gas hob is easy to use and, unlike an electric hob, the heat dissipates as soon as the appliance is switched off.

It happens that breakdowns occur: for example that the gas flame goes out just after it has ignited. In this case, it will be necessary to check:

  • the thermocouple
  • the burners
  • the injectors

If your hob is connected to gas bottles, first check that there is gas left in the bottle.

Gas hobs provide an excellent cooking experience, combining precision control and quick heating. However, one common issue faced by users is the hob flame going out during cooking. This can be an annoyance, but more importantly, it can pose a safety risk due to potential gas leaks. In this article, we’ll explore possible reasons why your gas hob flame might go out and how to troubleshoot them.

Why Does My Gas Hob Flame Go Out?

Unsteady Gas Supply

The flame on your gas hob may go out if there is an inconsistency in the supply of gas. This could be due to issues with the gas pipeline or the regulator.

Solution: Check the gas cylinder (if you’re using LPG) to ensure that it’s not empty. Also, inspect the regulator and the pipeline for any visible defects or damages. If you can’t identify any issues, you may need to call in a professional to examine your gas supply system.

Blocked Burner Cap

Over time, food particles and grime can accumulate and block the burner cap, causing irregularities in the flame and making it go out.

Solution: Regularly clean the burner cap and remove any food particles or residues. Be sure to follow your manufacturer’s instructions on cleaning to avoid causing any damage.

Faulty Thermocouple

A thermocouple is a safety device in gas hobs that stops the flow of gas if it doesn’t detect a flame, preventing a gas leak. If the thermocouple is faulty, it may misread the flame and cut off the gas supply.

Solution: If the flame goes out shortly after you release the control knob, it might be a thermocouple issue. This should be checked and replaced by a professional, as it involves dealing with the gas supply mechanism.

Why Does My Gas Hob Flame Go Out?

Drafts and Ventilation

If there’s a strong draft in your kitchen from an open window, door, or an air conditioning vent directed at the hob, it may cause the flame to go out.

Solution: Try to minimize drafts when using your gas hob. Adjust the direction of AC vents or close windows and doors to ensure steady airflow.

Low Flame Setting

If you have your flame set to a very low setting, it can go out, especially when cooking on larger pans that may cause the flame to spread and become too thin.

Solution: Increase the flame setting slightly to ensure that the flame is stable and adequately heats the pan without going out.

Conclusion

There are several reasons why your gas hob flame might go out, ranging from simple issues like drafts and blockages to more complex problems like a faulty thermocouple or an unsteady gas supply. Regular maintenance, including cleaning the burners and checking the gas connections, can help prevent many of these issues. However, always remember that gas appliances can be hazardous. If you’re uncertain or uncomfortable performing any of these tasks, don’t hesitate to call a professional technician to ensure your kitchen remains a safe space.
