Why Does Oven Make Noise When Heating Up?

If you are an active cook, you must be aware of the different types of noises an oven is expected to make. Rattling, clicking, Popping, hissing, whirring, humming and boom sounds are quite common oven noises. Though these are commonly heard, no one would like the oven to make noises.

No matter what is the sound emitted by your oven, it’s a cause of concern. Though the above-mentioned sounds aren’t serious, homeowners are advised to find out the cause of the sound and take appropriate measures to fix it.

Is your oven making noise while heating up? If yes, you mustn’t neglect the matter. If you are unable to find out the main reason behind such sounds, you have come to the right place. Read below to know what causes an oven to make noise.

Why Does The Oven Make Noise When Heating Up?

Why Does Oven Make Noise When Heating Up

By now you must know that ovens, especially gas ovens are capable of emitting different noises. Each of them is caused by different reasons. Without knowing how the sound is caused, you wouldn’t be able to solve it. Therefore, without delaying any further let’s go through the reasons that contribute to the emission of these sounds.

Your Gas Igniters Are Dirty

If you own a gas oven at your place, you are likely to experience this. Have you ever tried to heat the oven, only to get a boom noise at the start? That’s caused when the oven igniter becomes clogged with dirt, dust, and food particles.

A boom noise isn’t an indication of something serious, but one shouldn’t neglect it too. A boom sound indicates that the igniter is slowly becoming old and weak. It’s functioning but not as fast enough the light up the gas instantly.

We have explained how to solve this issue later in this post. As of now, we would move on to the further reasons that can cause weird appliance noises.

The Electrical Circuit May Have Tripped A Circuit Breaker

Home appliances require electricity supply to perform some tasks. If your oven has a circuit breaker and it somehow trips, the oven wouldn’t function. Therefore, before applying any solution, make sure you check the circuit breaker.

An Interruption in Gas Supply

Before turning on the gas, check whether the gas valve is on. Sometimes, the connection is cut off, which prevents gas from reaching the oven. In such cases, the oven wouldn’t heat up.

Faulty Cooling System

No matter you use an electric oven or a gas oven, sometimes you hear noises that are caused due to a malfunctioning cooling system.

Gas ovens get heated up more evenly when used. They therefore hardly need fans for temperature regulation. On the other hand, electrical ovens gain heat rapidly.  Therefore they need a better functioning cooling system so that the heat is transferred evenly.

Like we already mentioned, it’s likely for ovens to produce a subtle humming sound. That’s because the fans are turned on after the oven is preheated. But if you turn on the fan right from the beginning and hear certain noises, it can be due to any of the below-mentioned reasons:

  • The fan blades have become loose and they are colliding against the surrounding surfaces.
  • The fan motor is malfunctioning. As a result, it screeches while the blades are spinning.
  • Shaky body panels that vibrate. As a result, the fan shakes the entire oven when turned on.

These are some cases when a faulty cooling system makes noises. However, there’s nothing to worry about. These come with simple solutions. If you don’t want to solve the issues alone, you can definitely ask for a professional’s help. The maximum you might have to do is replace the worn-out parts or repair the malfunctioning parts. That’s all.

Defective Motor

If you have an electric oven at home, always remember to inspect the motor from time to time. The motor often breaks and fails to function properly.

So, how would you identify a malfunctioning fan? Does your fan make a lot of noise while spinning? Or does it run very slowly? Look for these signs.

If you notice any of these signs, you should definitely replace the old motor with a new one. But before buying a new one, it’s always advisable to get the oven inspected by a professional.

Now that we have gone through the reasons that can cause noises in an oven when heating up, we would go over to the solutions. The solutions are overtly simple and can be done at home. Nevertheless, we advise our readers not to experiment with anything on their own. Without any further delays, let’s now get into the detail.

How to Stop Your Oven From Making Noise When Heating Up?

How to Stop Your Oven From Making Noise When Heating Up

It’s normal for anybody to look for solutions when one notices the oven making noises when heating up. Though it’s true that not solving these sounds wouldn’t cause a catastrophe but it’s advisable to keep your oven in proper condition. Therefore, without any further ado, we would go through the ways in which you can prevent your oven from making weird noises while heating up.

Readjust The Air Shutter Present on the Gas Oven

When the gas oven starts to get heated, and you hear hissing sounds, adjusting the air shutter might solve the issue. You don’t have to worry about your gas oven making a hissing sound. It’s pretty normal. But, if it’s too loud, it means either the gas is in excessive amount or the airflow to the burner is too much.

No matter what the reason for the hissing sound is, the solution is pretty simple. We believe, adjusting the shutter present right behind the gas valve would be enough. To adjust the shutter, loosen the screws that hold the sliding plate in position. Next, adjust the shutter until the gas flame turns blue.

Even after doing this, if the sound persists, check the gas valve too. The hissing sound might also indicate the flow of the gas through improper channels. In case, you can’t stop the sound, you must contact a professional.

Clean the Gas Igniter

Do you know what’s the purpose of the igniter? It lights a small amount of gas to allow the gas oven to get heated up. Now, if the gas igniter remains dirty, it has to work overtime to heat the oven. Now when the igniter is dirty, gas keeps accumulating in the chamber. Now when the igniter finally lights up the oven, you hear a boom noise, because the accumulated gas is finally released. 

This kind of noise doesn’t however occur daily. But, clean the igniters regularly.

The igniter usually doesn’t get too dirty, because it’s situated underneath the oven. With time, dirt and dust accumulate at its bottom, causing it to work overtime to do its job. After a few months, it’s likely to accumulate little amounts of food particles and grease into its chamber.

If the igniter has become old, we advise our readers not only to clean it from time to time but also replace it and bring a new one. Don’t try to do it by yourself. Call a professional to handle the matter.

Sometimes foods too can build up in stove igniters. Therefore you need to check the igniter from time to time. In case, food particles have accumulated use a toothbrush to brush off any residue.

Check Whether the Fan is Functioning

We have already mentioned earlier how a malfunctioning cooling system causes unnecessary gas oven noises. If you want to stop that, you must ensure the fan is working in proper order.

Unscrew the back panel. Check the fan blades. Now, with your hand, try to rotate them manually and see if they are facing any obstruction while spinning. If the blades are colliding with its vicinity push the surfaces away. If you don’t think this is the right option, you can take a plier and bend the ends of the fan blades.

If you see the fan blades have become stiff and not spinning even when turned manually, you might be having a motor problem. To fix this you have to take off the fan blade. Remove the nut and detach the fan. Check the components closely. If you see the shaft at the back of the oven is bare, and it’s loose, try replacing the old motor with a new one.

People are advised to not replace the old motor by themselves. Any kind of negligence or ignorance on the part of the user can cause a disaster. However, if you are confident and willing to do it on your own, do as directed.

At the oven’s back, unscrew the cover, to get hold of the motor. There’s a wire connecting the motor. Detach that. Unscrew whatever holds the motor in place. Bring the new motor, secure it with screws and follow the process in vice versa.

Check Whether the Heating Components must be Replaced

Just like the gas igniter, other heating elements also cause crackling or Popping sounds. Excessive such sounds create  quite a lot of disturbance. Therefore, if you want to cook in peace, you must fix these issues first.

Heating components too gather dirt and dust, and therefore have to be cleaned from time to time. To clean it, allow mild cleaning solution to sit on the component for some time. Meanwhile, remove the shelves from the oven. Next, remove the bottom panel. Now apply whatever cleaning solution you want to apply to the component. If you are wondering what solution to use to do the cleaning, you can use baking soda or vinegar for the purpose.

If you see that the heating component is in poor condition, you have to replace it. To do that follow the following steps:

  • Unscrew the plate that holds the heating element firmly.
  • Remove the wires first.
  • Now, place the new heating element in place of the old one. Attach the removed wires to the new component.
  • Push back the coil. Make sure the metal plate touches the back wall.
  • Screw the plate in position.

If you don’t think you would be able to do it, call a professional any day.
