Why Is My Gas Cooktop Noisy?

29 March

To be honest, it can be pretty scary to hear odd noises coming from your gas cooktop.

Like most other appliances at home, the gas cooktops also have some distinct sounds. You can always hear that initial hiss of gas after turning on the burner or the clicking sound made by the igniter.

There’s no need to worry if you’re concerned about them, as most gas cooktops emit these sounds. Having said that, things can take a turn for the worse when the hissing or clicking sound doesn’t seem to stop. Instances exist where the noises persist even when you aren’t cooking anything.

Therefore, to put your mind at ease, we have come up with this guide to let you know what might cause these noises in your gas cooktop. We have also tried to provide the best possible solutions to deal with your issues. Please remember that you must practice caution when dealing with gas appliances.

So, let’s get started!

Reasons Behind Your Gas Cooktop Being Noisy

1. Issue In The Fuel To Air Ratio

Is a hissing sound coming out of your gas cooktop? If yes, it might be because of an imbalance in the fuel to air ratio. As you may know, the fuel needs to mix with the air for the burners to ignite, giving rise to the initial hissing sound we hear after turning on the burner.

However, this sound shouldn’t be too irritating or go on for a long time. The incorrect fuel to air ratio might be very prominent when the cooktop starts making a louder hissing noise. On top of that, an imbalance in the ratio often gives you flames that have yellow tips instead of the typical blue hue.

You don’t have to worry much about this loud hissing sound as you can easily fix it with a few things. Even though you won’t need to work with the gas line, it’s always recommended to turn off the fuel supply before working on the cooktop.


All that needs to be done is to remove the burner caps, burner heads, and even the top cover of your stove till you expose the air shutter. Have a look at your gas cooktop’s manual if you aren’t sure about where the air shutter is situated. It’s usually close to the burner tube, and you’ll notice a screw nearby.

Use the screwdriver to adjust this screw and make the slot smaller or larger. When yellow-tipped flames accompany the hissing sound, make the slot smaller as it’s usually a sign of too much air in the gas.

One thing to note is that you might need to do the adjustments a couple of times to finally get the hang of it. Be patient and check the flames for a bluish hue after the adjustments to ensure that the ratio is perfect.

2. Problems With The Igniter

As we said already, a typical sound associated with a gas cooktop is the click made by the igniter. It should last for about three seconds after you have turned the knob to ignite the burner because it lights the burner with a spark.

However, it’s a common complaint of many that the igniter may make the clicking sound for a long time without turning on the burner. This might be due to a faulty switch or a broken spark electrode that helps the igniter to light the gas.

The igniter may also start making a clicking noise if something boils over and spills on the burner. As a result, the igniter will attempt to start the burner but will not succeed due to the excess moisture. Due to this problem, an igniter may still make the clicking noise when the knob is turned off.


When the burner is wet because you spilled something over it, all you need to do is let it dry out for a few hours. Make sure to turn off the electricity for the igniter before you leave the stove to dry. If there’s too much spillover liquid on the cooktop, try switching on your oven at 175°C for 30 minutes to help it dry out.

In other cases, you may take off the burner cap and clean the igniter by rubbing a little bit of alcohol on the dirty area. Ensure that the liquid has dried off completely before putting back the burner cap, and it should be good to go.

3. Problem With The Gas Regulator

One sound that does call for trouble is when the gas cooktop makes a whining sound due to a problem maintaining proper gas pressure. This usually points to a fault in the gas regulator, and in most instances, it needs to be fixed by a professional.

Even without the sound, you may notice issues with the regulator, as the burners give out a weak flame. We recommend contacting the brand’s customer care to book an appointment with them to fix your gas cooktop. They usually replace the faulty regulator with a new one to ensure no gas leakage while maintaining uniform pressure.
