A gas oven basically works by letting a controlled explosion to take place in the burner. When you turn the knob of a gas oven, the gas valve allows a small amount of gas to flow through a burner tube. After that, an igniter ignites the gas causing it to light up in flames. Noise coming from the gas oven can frighten many people.
Gas ovens can naturally produce some distinctive sounds. But gas oven sounding like a blow torch is not a natural sound. Gas oven making this type of sound indicates some kind of mechanical malfunction with the oven. There are many crucial parts in a gas oven. As a result, it is very difficult to determine which part is responsible for the noise.
In this article, we will discuss and find solutions to why a gas oven makes a noise similar to a blowtorch. We will also discuss and solve other noise problems of gas ovens as well.
Why Does A Gas Oven Sound Like A Blowtorch?
Your gas oven can sound like a blow torch because of the following reasons:
A Defective Igniter
As mentioned above, the igniter helps to ignite the gas coming from the gas valve. A faulty igniter can be the reason for your gas oven to sound like a blowtorch. An ignitor can go bad because of being used for a long time or because of being too dirty. We can solve this problem by changing the igniter.
We will discuss the process of changing an igniter later in this article. Unfortunately, changing the igniter requires very high technical skills. So do not attempt this process if you do not have the required skills.
A Fault In Regulator Valve
A regulator valve dictates the amount of gas that will flow to the burners. Having a very high rate of gas flow can make your gas burner sound like a blowtorch. Adjusting the regulator valve should stop the high rate of gas flow. You can adjust the regulator valve by watching a video on YouTube.
But if your burner still sounds like a blowtorch even after adjusting the regulator valve, then you may have to call in professionals for a complete replacement of the regulator valve.
A Problem in FSD
An FSD or Flame Supervisory Device is a device that completely disconnects the flow of gas to the burner if it senses the flame on the burner has been extinguished. A malfunctioning FSD can cause the burner to sound like a blowtorch. Therefore, by replacing the FSD you can eliminate the noise issue.
Additionally, a misaligned ignitor can cause your gas stove to sound like a blowtorch. A delayed ignition can also cause this problem as well.
Different Gas Oven Related Sound
Now we will discuss different noise problems with the gas oven. These Problems are Mainly:
- Whooshing Sound
- Puffing Sound
- Booming Sound
- Clicking Sound
Gas Oven Making Whooshing Sound
If you hear a gas oven whooshing sound, then you need to deal with it urgently. Whooshing noise made by your gas oven is definitely not a good sign. The sound is an indication of a failing glow bar.
The glow bar or igniter is a device that helps to ignite an oven when gas is supplied. The glow bar is generally seen in gas-range electric ovens. It functions almost like an electric heating coil. The gas valve automatically opens up when the glow bar gets hot enough. Electric current helps the glow bar to reach the required temperature for the automatic gas valve opening.
The delayed ignition of the glow bar is the reason why whooshing noise happens. As a result of the delayed ignition, a small amount of gas builds up around the area of the glow bar. And when the glow bar finally reaches the ignition temperature, a whooshing noise is produced during the ignition process because of having to burn more gas around the ignitor.
In order to solve this problem, complete removal of the faulty glow-bar/ignitor is absolutely necessary. The steps by following which you can replace a glow bar are:
- Start by disconnecting the electrical power to the oven. Also, make sure to close the gas supply.
- Wear safety gloves because the parts inside the oven can be very sensitive and can get damaged because of the oil on your hands. Especially the carbide electrode.
- Remove the trays from the oven. After that, remove the bottom panel situated on the inside of the oven. The panels would be secured by screws and can be opened by a screwdriver.
- After removing the bottom panel, you can see the exposed glow bar. The glow bar would be connected to a wired harness secured in the bracket by a screw.
- Use a screwdriver to remove the screw and remove the glow bar from the bracket. After doing so, disconnect the glow bar from the wire harness.
- Reattach the wire harness with the new replaced glow bar and secure it in place with the screw.
- Close the bottom panel and reconnect the electrical power. Do not forget to turn the gas supply on as well.
Gas Oven Making Puffing Sound
A faulty gas valve can be the reason why your gas oven makes puffing sound. The gas valve is a device that regulates the flow of gas in the burner. Your gas oven can make a puffing noise if the gas valve sends too much gas to the igniter before the ignition takes place. You will definitely be needing an expert technician for the repair and possible replacement of the gas valve.
An unadjusted air shutter can also be the culprit behind this problem. An air shutter regulates the amount of oxygen that will be mixed with the supplied gas. Generally, gas stoves that make a puffing sound, also tend to produce a yellow flame while burning. An incomplete combustion of gas is the reason for yellow flame and this can also be the cause for puffing sound.
So, adjust the air shutter for proper combustion of gas. You will know a proper combustion is taking place in your burner if the flame produced by your burner is blue instead of being yellow. You should replace your gas stove if still makes a puffing sound even after replacing the gas valve and adjusting the air shutter.
Gas Oven Making Boom Noise
Just like the whooshing noise, the gas oven makes boom noise due to the delayed ignition of the gas. As mentioned earlier, whooshing noise happens because of the delayed ignition of a small amount of gas accumulated around the igniter. But, Boom noise happens when a large amount of gas is accumulated around the ignitor and is ignited because of the delayed ignition.
This issue mostly takes place because of a faulty igniter or because of the igniter being covered with dust and grime. Properly cleaning the ignitor solves this problem for most people. For cleaning the ignitor, you have to remove it first. And for removing the igniter, you need to follow some certain steps that have already been discussed previously in this article.
Use a stiff toothbrush for the cleaning process. Properly clean all the surfaces of the igniter and reconnect it with the oven. If the problem still persists, replace the ignitor with a new one.
Gas Oven Making Clicking Noise
Gas oven making clicking noise is actually a very common problem. Many people face this clicking noise problem after the burner is switched off. There are many reasons for a gas oven to make a clicking noise. The most common reason is because of the accumulation of food debris around the ignitor. A proper clean of the area around the ignitor can solve this problem.
Furthermore, the gas oven can make a clicking noise because of a misaligned burner cap. In order to properly align the burner cap, at first remove the burner grate. After doing so, give a gentle push to the burner cap. The cap should fall in its groove and should not move around even after applying force.
Moisture deposition can also aid the clicking noise problem. Moisture can accumulate around the igniter area because of a water spill or because of improper cleaning. You can get rid of the accumulated moisture by properly drying the stove. You can use a hairdryer or a paper towel to dry the stove.

Your gas oven can make many additional noises for many other reasons as well. For example, a roaring sound is produced by the gas oven when too much gas enters the oven. A malfunctioning venturi tube letting excessive secondary air into the burner can cause this problem. Furthermore, if your gas oven makes noise when heating, properly clean the igniter.
Many people tend to neglect different types of noises coming out of their burner. Doing such a thing is definitely not recommended. A noisy burner is the sign of a possible mechanical malfunction and raises health and safety concerns. That is why always deal such matters with maximum priority.
Try the fixes mentioned above all by yourself if and only if you have good mechanical skills. Do not forget to disconnect your oven from the gas and electricity supply before trying any of the above fixes. Do not hesitate to call in a professional technician for a proper inspection and repair of your gas oven.
