Gas Oven Sounds Like A Blowtorch (Causes and How to Fix)

Imagine walking into your kitchen, ready to whip up a delicious meal or bake a batch of cookies, only to be greeted by a surprising and somewhat unsettling noise. Instead of the familiar hum or tick of your gas oven, it sounds like a blowtorch is raging within its depths. Your mind races with thoughts of potential dangers, wondering whether your kitchen is about to transform into a scene from a Hollywood action movie.

Fear not, for you’re not alone in experiencing this perplexing phenomenon. Many homeowners have encountered the unsettling issue of their gas ovens producing sounds reminiscent of a blowtorch. While it’s natural to be concerned about safety, it’s essential to understand that these sounds often have less dramatic explanations than one might think. In this blog post, we will delve into the world of gas ovens, exploring the reasons behind these blowtorch-like sounds and helping you determine whether they warrant a call to the repair technician or simply a deeper understanding of your kitchen’s quirks.

1. Igniter Issues

A faulty igniter is often the culprit behind the blowtorch-like sound in your gas oven. The igniter is responsible for initiating the gas combustion process. If it’s not functioning properly, gas can build up before igniting, resulting in a sudden burst of flames that produces the distinctive sound.

Troubleshooting:

• Turn off the oven and disconnect the power.
• Locate the igniter, usually located near the burner.
• Inspect the igniter for any cracks, discoloration, or visible damage.
• If damaged, replace the igniter with a compatible replacement part.
• If the igniter looks fine, use a multimeter to test its electrical continuity. If it’s not within the acceptable range, replace it.

2. Burner Obstructions

Obstructions in the burner ports can disrupt the flow of gas, leading to uneven combustion and the blowtorch-like sound.

Troubleshooting:

• Turn off the oven and ensure it’s cooled down.
• Remove the burner covers or grates to access the burners.
• Carefully inspect the burner ports for debris, grease, or food residue.
• Use a soft brush or compressed air to clean out any obstructions.
• Reassemble the burners and turn on the oven to check if the sound has resolved.

3. Gas Valve Issues

A malfunctioning gas valve can result in irregular gas flow, leading to uneven combustion and the blowtorch-like noise.

Troubleshooting:

• Turn off the gas supply to the oven.
• Consult the oven’s manual to locate the gas valve.
• Inspect the gas valve for visible damage or signs of leakage.
• If there’s damage, replace the gas valve with a compatible replacement.
• If no visible damage is present, turn the gas supply back on and observe the oven’s performance.

4. Gas Pressure Problems

Inadequate gas pressure can cause an uneven mixture of gas and air, leading to improper combustion and the characteristic blowtorch-like sound.

Troubleshooting:

• Check if other gas appliances in your home are functioning correctly. If they’re not, contact your gas provider.
• If other appliances are fine, consult a professional technician to measure and adjust the gas pressure for the oven.

5. Dirty Flame Sensor

A dirty or malfunctioning flame sensor may not detect the presence of a flame, causing the oven to release gas before ignition and creating the blowtorch-like noise.

Troubleshooting:

• Turn off the oven and disconnect the power.
• Locate the flame sensor, usually located near the burner assembly.
• Gently clean the flame sensor with a soft cloth or fine-grit sandpaper to remove any buildup.
• Reconnect the flame sensor and power, then turn on the oven to check if the sound has disappeared.

6. Improper Airflow

Insufficient airflow within the oven chamber can lead to an uneven mixture of gas and air, resulting in the blowtorch-like sound during combustion.

Troubleshooting:

• Ensure that there are no obstructions in the oven vents or exhaust.
• Avoid overcrowding the oven with cookware, as it can disrupt airflow.
• Use oven-safe cookware that allows proper circulation of air.
• Check if the oven’s internal fan (if applicable) is functioning correctly.

7. Incorrect Gas-Air Ratio

A skewed gas-to-air ratio can lead to incomplete combustion, causing the blowtorch-like noise.

Troubleshooting:

• This issue is best addressed by a professional technician, as adjusting the gas-to-air ratio requires specialized equipment and expertise.
• Contact a certified technician to diagnose and correct the gas-to-air ratio for optimal combustion.

8. Delayed Ignition

Delayed ignition occurs when the oven takes too long to ignite after the gas is released, resulting in a buildup of gas that ignites suddenly with a blowtorch-like sound.

Troubleshooting:

• Turn off the oven and disconnect the power.
• Check for any blockages in the burner assembly or igniter that might be causing the delay.
• Clean or replace any faulty components causing the delay, such as clogged burners or a malfunctioning igniter.
• Reassemble the oven and turn it on to observe if the ignition is happening promptly.

Other Gas Oven Sounds to Watch Out For!

Some of the noises you’re likely to face include: puffing sounds, roaring noises, popping noise, clicking noise, high pitched noise, boom noise, and whooshing sounds.

Puffing Sounds

Puffing sounds occurs when there’s delayed ignition resulting in too much gas escaping before ignition. The sound is often heard from the baker burner ignition located just under the floor of the oven. Several causes include weak glow bake ignitor, incorrect air mixture, or faulty gas valve. You can fix this problem by simply adjusting the air shutter or simply involving a technician.

Roaring Noises

There are several causes of roaring noises in a gas oven. They include: Over gassed gas oven- the orifice could be wide open or excess gas volume. You should contact the gas company to help fix the problem. On the other hand, roaring noises could be caused by secondary air supplying entering the burner venturi tube. You can fix this problem by simply adjusting the air shutter for less air intake- but do it carefully to avoid closing the air shutter completely.
