Your oven is the centre piece of your kitchen. It’s where you grill fish, cook pizza, and heat up leftovers. As such, it’s important that it’s always functional, because without it, your kitchen simply isn’t complete. This fact causes many people to worry when they hear their oven fan making a lot of noise.

In this article, we’ll explore what your oven fan does, why it may be noisy, and how you can fix it.

What Does an Oven Fan Do?

An oven fan uses convection to maintain heat. The fan, situated at the back of the oven, helps to circulate air round the interior of the oven. This keeps a constant temperature within the oven, allowing for easy cooking and roasting.

If convection ovens didn’t have fans, you’d notice very uneven cooking. They’re ultimately a vital part of your oven, and if it becomes damaged, it can be a real cause for concern.

Is a Noisy Oven Fan Dangerous?

Many ovens make a variety of noises whilst they’re on, and they’re perfectly normal and no cause for concern. However, a noisy oven fan is particularly loud, and certainly not normal, which causes many people to worry.

However, a noisy oven fan isn’t dangerous. If your oven fan is damaged, it’s not going to increase the likelihood of fires, electric damage, or any other problems. Instead, a noisy oven fan is simply an indicator of a problem with your oven, that can normally be easily fixed.

The only real danger of a noisy oven fan is that your fan may not be working properly. This could cause your oven to overheat, damaging other areas of your oven and even hob. So, it’s best to address this problem as soon as you hear it, as it could save you a lot of time and money down the road.

3 Reasons Your Oven Fan Is Noisy

1. Faulty Fan Motor

One of the leading causes of oven fan noise is a faulty fan motor. The fan motor is what causes your fan to spin. So, if this becomes faulty, there’s a good chance your fan is going to get loud quickly.

You can fix the fan motor yourself. Firstly, turn off and unplug the oven. It’s imperative that you always turn off appliances when attempting to fix them. If you don’t, you could earn yourself a trip to hospital.

Next, remove the oven’s inner panel, using a screwdriver. This will give you access to the oven fan. Try spinning it by hand. If it feels stiff, this is a good indicator that you’ll need a new fan motor. You can attempt to fit one of these yourself, but it’s a complicated job, so you may want to call a professional for help.

This is one of the leading causes of fan noises, so should be the first thing you check when you try to diagnose the issue.

2. Loose Fan Blades

A loose fan blade is another very common, but thankfully easily fixable, reason why your oven fan is making lots of noise. If your oven fan is loose, then it may rattle a lot, or even hit the sides of the oven.

To fix a loose fan blade, turn off and unplug your oven. Next, tighten any loose bolts or nuts that are attached to the fan blade. Tighten them as much as you can but be careful not to split the fan blade or crack it- it’s very delicate and too much force could break it. This should stop your fan blade from making loud noises.

3. The Mechanism Is Faulty

There are a lot of things that can go wrong with your fan oven. One of the most common parts to break or become faulty is the bearings and spindle. When these become worn or damaged, they can rattle and produce a lot of noise. You can check if worn bearings are the cause of your noisy oven fan easily. Simply turn off the oven and unplug it.

Next, disconnect the fan’s connectors and insulate them with tape. Finally, turn on your oven. If there is still noise, then you’ve most likely got a problem with your bearings or spindle. Damage to these parts is normally irreversible and you’ll have to replace them altogether.

Why Is My Oven Rattling?

When your oven rattles, it can be one of the most annoying sounds you could imagine. But why does it rattle, and how can you fix this?

Your oven rattles because of loose screws and bolts within the mechanism. Loose bolts occur over time and are not a cause of concern. However, the more you leave them, the looser parts of your oven will become, which could result in some serious damage.

Luckily, fixing a rattling oven couldn’t be easier. Simply make sure that your oven is off and unplugged – you don’t want to harm yourself or others! Next, go around the oven and tighten all the bolts you see.

You’ll want to focus on the screws and bolts in and around the oven fan, as these tend to come loose over time. Once you’ve tightened all the screws and bolts, plug your oven back in, and you should find that it’s no longer making noise.

Why Is My Oven Buzzing?

When your oven makes a buzzing noise, it can be a major cause for concern. So, why does your oven buzz, and what can you do to fix this?

First, buzzing may just be a normal part of your oven. Some ovens are louder than others and depending on the brand and age of the oven, it may make a buzzing noise every time it’s on. This is no cause for concern, and more of an inconvenience than a fault.

Alternatively, a buzzing sound may mean that the cooling fan is operating. Cooling fans turn on after a cycle completes, and it’s perfectly normal to hear such noises when you turn your oven off.
So, your oven buzzing is perfectly normal, and you shouldn’t feel that you need to worry about it!

So, there’s pretty much all the information you’ll need to fix a noisy oven fan. Most problems are simple to fix, and by fixing them yourself, you’ll save a lot of money.

And, some noises, like buzzing, shouldn’t be a cause for concern. But, if you ever feel that your oven isn’t operating properly, and you don’t feel comfortable looking at it yourself, call a professional.
