DIY Fixes: Gas Oven Sounds Like A Blowtorch in 2025

It’s not uncommon for people to be taken aback by the intense roaring sound of a gas oven. Sometimes gas oven sounds like a blowtorch and it can be startling when you’re trying to cook dinner, especially if you’re using one for the first time.

In a brief overview, there are three possible suspects. The first is that the ignition was delayed. The second is that there is too much air. And the third is that the ignitor probably isn’t lined up well.

The good news is that there are some DIY fixes that try to get rid of this sound.

How the Gas Oven Works

To know why your oven sounds like a blowtorch, you need to know how it works.

Firstly, you set up the oven temperature according to your desire.

When the ignitor is activated, it sends a signal to the gas valve which then increases in pressure.

The increased pressure causes an explosion of natural or liquefied petroleum gases that are used as fuel and burn instantly at high temperatures.

This process heats up the oven’s metal coils called burners, which transmit heat through radiation into the food inside; thus cooking your meal.

If you notice any unusual sound from your oven, it is likely to be related to the gas valve or any other part that regulates the pressure.

There are many different reasons why there is a sound in the oven. You need to take your time figuring out what the problem is.

Gas Oven Sounds Like a Blowtorch Causes

Different types of problems could be causing your gas oven to make sounds.

If you know what is wrong with your oven, then you can decide if you want to wait for a new one or if you want to fix it.

The reasons your gas oven sounds like a blowtorch are:

Faulty Ignitor

if the igniter has been working fine and suddenly it doesn’t work when you try to turn on the oven, first check if the igniter is lined up properly.

If that is not the case then there might be a problem with the gas pressure regulator adjustment or replacement (which requires professional service).

Some other potential problems could be: too much air in your home’s piping system and/or delayed ignition because of obstruction around the connector tube between burner and valve.

If the ignitor is the problem, this is a quick fix and you can save on the repair costs if you see a glow in your oven,  then that is a good sign that your oven is in a good shape.

In addition, If the ignitor is not working properly, then your gas oven may be making popping sounds or it could sound like an old-style blowtorch when you turn it on and off. 

Misaligned Ignition

The ignition may be working okay but not lined up properly, which can cause the blowtorch sound.

To check for this problem: remove one of the oven racks and insert a long-handled matchstick or other objects into the burner hole at an angle.

If it starts to flame, there’s no alignment issue.

If not, you’ll need service by a qualified appliance technician and they will correct any misalignment.

Flame Supervision Device (FSD)

a faulty flame supervision device (FSD) could be the cause of your gas oven sounding like a blowtorch problem. You can easily swap it out on your own, which is more cost-effective than hiring an appliance repairman to do so for you.

if the FSD is faulty, it could be caused by a dirty flame arrestor.

The following steps are how to replace the FSD:

Unplug your oven from its power source and shut off any gas valve on top of or near the oven area.

Remove all surface covering material on or in front of the unit cabinet doors to expose accessibility for changing out the device inside the vent panel.

Locate and remove screws holding down hinges of door panels, then take them apart by removing their rivets.

Take care not to damage these items while doing so (you might need them again).

Be sure that you disconnect wires attached to terminals at the back side before taking this step too; do not forget which wire goes where!

If it doesn’t work, let a professional do it for you.

 Regulator Valve

When you hear a lot of noise, it could be that there is something wrong with the regulator valve.

If there is no other problem, then you might need to adjust the valve or replace it.

Gas Pressure

A regulator valve is needed to regulate the flow of gas and that is what a pressure regulator does.

It means  that the pressure of each burner will be regulated to a fixed point

The regulator valve is what regulates how much gas gets into your oven.

The flow of gas from the tank into your appliance must equal that specific burner.

Therefore, if you notice that one side has too little fuel and another side may have an excess, this could cause blowtorch noise, when igniting the burners because it runs out and backfills with more air than necessary.

If the noise continues after you have replaced the regulator, you might need to check the pressure.

Other Gas oven related sounds

Many more interesting sounds could mean a severe problem.

These problems include:

Roaring Sounds

This type of noise is often produced when too much gas gets into the oven.

We can hear the sound of the gas burner.

The noise is usually a sign that there are problems with your oven’s burners or valves.

You need to call an expert immediately because it may be dangerous.

If you don’t want to wait, try turning off all of the gas and make sure not to use any appliance until it is fixed by professionals.

Popping Sound

if you hear some popping sound from your gas oven, this might be caused by a dirty flame sensor.

• Unplug the range and stove top for safety purposes
•  Disconnect the wires from the flame sensor. Take it out of its bracket with caution so you do not break any connections or bend any pins. Blow off all dust on both sides using compressed air if necessary
• Put back together in reverse order and plug appliance back in to test results

Some other common causes of this noise are a gas leak, a blocked injector nipple, and a damaged gasket.

Whooshing sound

The whooshing sound is the most common of all gas oven sounds.

If the glow bar does not light before the gas is released, you might hear a whooshing sound. This sound is produced when the glow bar eventually lights up.

The whooshing sound is not usually a sign of any problem with the oven.

However, it could be caused by using an old or worn-out glow bar.

A technician should examine this issue to determine if there is anything wrong with your gas oven.

Puffing Sound

The problem could be with how much gas is getting to the burner. You need to check the gas valve and get a replacement if it is not working correctly.

Booming Sound

When the oven is preheating you can hear the booming noise due to delayed ignition.

This is because the flame in the oven’s burner has not ignited.

The problem may be due to too much air or a faulty ignitor that can’t ignite the gas properly.

Fixing this issue will need some adjustments on your furnace settings, cleaning out accumulated dust from burners, etc., but it won’t cost you anything extra for professional help.

Clicking Noise

A clicking noise could be a warning sign that there is an issue with the gas oven. It could mean that you have too much pressure and need to address it by replacing or adjusting your regulator.

Clicking Noise can also be caused by other things like a problem with the burner cap.

Sometimes it happens because there’s some wetness left on the stove after something spills.

Other times, food might be blocking the igniter so it can’t start making heat.

Also, dryness in the air vents will clog up the pipes and cause them to vibrate when they heat up.

If the problem continues after you clean your cooktop and try to turn it on, you may need to replace the burner cap or the ignition switch.

Final thoughts on Gas Oven Sounds Like a Blowtorch

We hope this article has been helpful in helping you determine the cause of your oven’s noise.

If you have a gas oven that sounds like a blowtorch, then there are some simple things you can do to make it quieter.

You can try turning up the flame on low heat or use aluminum foil as an insulator for the fan and coils.

As always, if it persists or gets worse over time we recommend consulting with a professional who is knowledgeable about heating appliances so they can diagnose and fix any problems.
