If your gas oven sounds like a blowtorch, below are some of the best ways to fix this problem.

In a brief overview, the possible culprits, in this case, could be delayed ignition, too much air, the ignitor probably isn’t lined up well.

It could also mean that you need gas pressure regulator replacement or adjustment.

However, to fix this problem, we need to first understand how the gas oven works.

How the Gas Oven Works

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

First, you set the oven to your desired temperature.

The power is then sent to the ignitor, and once it is energized, the ignitor draws the necessary current.

Once the desired current is reached, the gas safety automatically opens, allowing gas to flow into the oven’s burner assembly.

The gas is ignited, and the oven starts to heat up.

As the oven temperature rises, the oven sensor converts it into an electrical signal, which you see on the temperature display.

Models with a dial thermostat often do not have a sensor but a metal wire connected to the thermostat.

If you notice any unusual sound from the oven, any of the above parts could be faulty. The gas pressure could also be off.

Given that there are many causes of different sounds in the oven, you have to take your time to figure out what is happening. 

Gas Oven Sounds Like a Blowtorch Causes

While you may not be in a position to fix the problem, knowing which part is faulty will help you make an informed decision on whether to repair or wait until you get a new oven.

There are many reasons why your gas oven sounds like a blowtorch. These include:

1. Faulty Ignitor

If the igniter is damaged, you have no choice but to replace it with a new one.

However, the process is straightforward, and you can fix the problem if you know your way around the oven.

Just ensure that you have the model number and oven manufacturer in mind when shopping for a replacement.

You can also call a professional to repair the oven and shop for the right ignitor for your oven.

To check whether the ignitor is the problem, turn on the oven and wait for about 20 seconds.

If you see a bright glow in the oven, then the ignitor is okay.

No gas will flow into your oven if the ignitor is faulty, so there will be no glow even when you have turned on the oven.

If you see a weak glow, there is a chance that the igniter is just dirty.

Check for food debris and use a toothbrush to remove any stubborn dirt stuck on the ignitor surface.

2. Misaligned Ignition

The ignition may be working okay, but you will hear the blowtorch noise if it is misaligned. This may not happen every time you light the oven.

Getting the ignition corrected will help resolve the problem.

Just call a professional and let them correct any misalignment.

3. Flame Supervisory Device (FSD)

A faulty Flame Supervisory Device could also be causing the blowtorch noises.

If the FSD is not opening correctly, it is starving the oven burner of gas, so the delayed ignition causes the noise.

It may be hard to diagnose an FSD problem, so it is always wise to engage a professional.

Just take the steps you can without having to open the oven and if it doesn’t work, let a professional troubleshoot and come up with a solution.

4. Regulator Valve

If you hear blowtorch noises, you could also be dealing with a regulator valve problem. Depending on the situation, you may need to adjust or replace the regulator valve.

5. Gas Pressure

A regulator valve works to ensure that just the right amount of gas is getting into the oven.

This means that you will never have to worry about the gas pressure with a good regulator valve.

However, if you get a new regulator and the blowtorch noise is still persistent, it may be time to check on the pressure.

Other Gas oven related sounds

Many more unusual sounds could indicate a more severe problem.

Some of these problems include:

Roaring Sounds

There are often produced when there is too much gas getting into the oven.

You can control this through the gas regulator in the oven or at the meter.

The venturi tube in the burner could also be allowing too much secondary air supply.

This can be easily regulated through the air shutter, but you should careful not to close it too much; otherwise, you will have yellow tips.

Popping Sound

If you hear some popping sound, the burner cap could be misaligned, or some liquid may have found its way into the burner cap or the burner.

You may also have some dirt blocking the burner orifices.

The popping sound could also indicate a damaged igniter or igniter wire.

Other common causes of this noise include leakage in the gas connections, blocked injector nipple, and a damaged gasket.

Whooshing sound

If the glow bar doesn’t get ignited before the gas is released, you may hear some whooshing sound. This sound is produced when the glow bar finally ignites.

Basically, this problem results in a minor explosion.

To solve this problem, just replace the glow bar ignitor.

The whooshing sound could also be coming from the top burners.

When the gas regulator is worn out, the top burner may start misbehaving.

Puffing Sound

This often happens if there is too much gas getting from the bake burner before it is ignited. Check the gas valve and get a replacement if it is faulty.

Booming Sound

If you hear some booming sound when the oven is pre-heating, delaying ignition could be the issue.

This boom is when the accumulated gas finally ignites.

When you experience the booming sound, remove any dirt, grime, and grease from the ignitor.

In most instances, a thorough clean is all it takes to resolve this problem.

Clicking Noise

A clicking noise is nothing to worry about. The oven can continue clicking even when you have shut the gas off.

The clicking can be caused by a misaligned burner cap, some moisture lingering mostly after a spill, and some food debris blocking the ignitor.

If the problem persists after realigning the burner cap and cleaning the cooktop, you may need to replace the ignition switch, the ignitor, or the spark module.

Final thoughts on Gas Oven Sounds Like a Blowtorch

If your gas oven sounds like a blowtorch, you can fix it by utilizing the above simple yet effective methods.

There’s no need for alarm as some of these noises are normal, but others are an indicator of an underlying problem.

If you’re worried that you got a serious problem to deal with, then you’d probably be better with calling a professional.
