Gas Stove Noises When It’s Off: Complete Guide to Causes and Fixes

According to recent data, over 40 million Americans own a gas stove. It would be an understatement to say that it’s an item that modern households almost can’t do without. And if you use a gas stove frequently, chances are that you might hear it make some noise, even when it’s off.

Of course, the noise you hear may be nothing serious, but it may also be a sign of a much larger problem. So, in this article, you’ll learn what type of noises a switched-off gas stove tends to make. In addition, you’ll find some common methods on how to get rid of them.

Different Types of Noise

Much like microwaves and refrigerators, gas stoves can produce various types of sounds when they’re off. Listed below are the most common ones you’ll come across.

Clicking

There can be one of two possible causes when you hear a clicking noise coming from your stove.

The first of the two is the igniter that’s just under the burner. More often than not, this noise is harmless, and you’ll learn how to deal with it a little further down the article.

However, sometimes the clicking can come from the thermostat, i.e., the temperature control knob. If there’s an issue with the thermostat, it will make a clicking noise when you try to turn it. The second you hear that kind of noise from this source, contact a professional.

Buzzing

If a part of your oven is loose, you can hear a buzzing noise coming from it. At times, it can be a low, droning kind of buzz. But there are times when it can be extremely loud and obstructive.

Sparking

Hearing a sparking noise when the oven is off is usually fairly harmless. That’s only the sound of the electronic ignition system since it uses a spark to light the burners. However, if this sound persists once the oven is on, it’s time to seek professional help.

Ticking

Different oven parts, such as the burner head, base, and gas valve, are made of metal. These parts tend to contract and expand due to extreme temperature changes such as heating and cooling. As they do, they often make ticking sounds.

These ticks are fairly common with every gas stove, both old and new. And considering where they come from, they are not a cause for alarm.

Humming

The final type of noise you may come across when your gas stove is off is humming or even whistling. This type of noise tends to be caused by a malfunctioning regulator valve. The hums can be low and droning, but sometimes, they can have a high pitch and sound like whistling from a tea kettle.

What Causes the Noise in Your Gas Stove?

Now that you know what kind of sounds you can expect, let’s focus on what the main culprit behind them can be.

Expanding and Contracting Metal Parts

As stated earlier, there are several components to each gas stove that are made of metal. The most common ones are burner heads, bases, gas valves, and pan support.

When we use the gas stove, these are the sections that will heat up, and they will stay hot for a while even after we switch the stove off. As they cool, the metal slowly contracts, making light noise as it normally does during this process.

Regulator Valve

In both gas stoves and ovens, a regulator valve is a device that controls how much gas flows to the burners. If the valve itself malfunctions or if there’s an issue with gas pressure, it will make a whistling or humming noise, even when the stove isn’t in use.

Igniters

Normally, a gas stove would have an electronic ignition system. It uses a spark to light the burners, and the noise it makes comes from grime and grease build-up 90% of the time.

Air in the Gas Line

If you don’t use the stove for a little while, air can get stuck in the gas line. That can also happen if the line has a leak somewhere that’s letting the air inside. Interestingly enough, trapped air is a fairly common issue that all gas stoves have at some point.

Loose or Worn-Out Parts

With age, as well as frequent use, it’s expected for certain parts to wear out. As such, they will be loose and wobbly, and that can cause some minor noise.

What Can You Do About It?

Humming Noise Fix

As stated earlier, the humming can come from either the regulator valve or the gas line. If the former is the issue, it’s best to call a professional to look it over.

On the other hand, if the gas line has a leak, you can replace it yourself. All you need to do is purchase a new gas line that fits your specific stove model and follow the instructions laid out in the product manual.

Ticking Noise Fix

Slight ticking after using the stove is normal. However, if it continues to tick for a long time after use, you can either replace the old metal parts or call a technician to check it. There might be an underlying problem that requires a professional approach.

Sparking Noise Fix

Once again, there could be multiple reasons behind this noise. One of the most common ones is the spark module. If that’s the source of the noise, you can easily get rid of it by simply replacing the old module with a new one. Alternatively, you can replace the entire electrode.

At times, merely cleaning the igniter will do the trick. You can do it by using a cotton swab or a paper towel. It’s also a good idea to clean the area directly underneath the igniter so that no debris can catch fire or cause the sparking.

Buzzing Noise Fix

With buzzing noises, all it takes is some tightening or realigning. More than likely, the burners and the caps are not placed properly and just need to be moved a bit. If they are too loose, consider buying and installing new caps and burners.

Clicking Noise Fix

Since clicking is linked to the thermostat, you can’t exactly do a DIY on it. That will require a professional, so we recommend giving them a call the second you hear this type of noise coming from the temperature regulator.

Additional Noises Fix

When you use your stove, and there’s some residual gas, it will normally pop when it gets ignited. However, that’s nothing to worry about, considering the noise is short-lasting.

However, the situation can be more dangerous if the popping is the result of a faulty valve or improper venting. With a faulty valve, gas can leak out of the line. Alternatively, should you forget to vent the stove properly, gas fumes will accumulate.

In both cases, the popping noise will be loud and sudden, both when it’s off and when you switch it on again later. It’s also a massive hazard, so make sure to get the repairs done as quickly as possible.

Gas Stove Noise, Summed Up

Sometimes, the sounds that your stove produces while it’s off can be harmless, and other times, they can be life-threatening. Whatever the case may be, and no matter how safe you think it is, it’s always a good idea to talk to an expert and have the stove looked at.
