Reasons Breville Toaster Oven Fan Making Noise?

Breville toaster ovens have conventional options too, that is their plus point. But it creates issues for users when they start hearing unusual noises and sounds from their Breville toaster oven.

There are several reasons why the conventional Breville toaster fan starts making noise. 

Reasons such as when the toaster oven has been used for more than two years, when it loses lubricant, stuck dirt particles in fan blades, and fan motor problems.

Let’s take a deeper look at these causes of conventional fan noise on a Breville toaster oven:

  • When the toaster oven has been used for more than two years: if you say that how much does a Breville toaster oven last? The answer is simple: as long as it works. 

On average Breville toaster ovens last more than 5 years. If by chance the unit has weakened for a few months, a lasting part such as a conventional fan. The fan will start to make noise due to overuse. 

However, it’s not overused by conventional fans if we talk about its lifespan. But nobody knows when malfunction gets created in a component.  In case the fan still works but only makes a humm or grinding noise, you can fix it easily.

  • When it loses lubricant: lubricant helps the fan shaft to rotate easily with zero friction and burden. It speeds up a slowly rotating shaft with its properties and grease. 

We have fixed some noisy convection fan problems of many toaster ovens, we just used lubricant spray to lubricate the fan to run properly like a new one. 

Sometimes rust or dust gets stuck in the motor where the shaft starts viewing from the motor side. Once you lubricate that part, it will prevent rush or dust from being stuck in. 

  • Stuck dirt particles on fan blades: Breville smart toaster oven has a  fan on the right side. The front cover of the fan has an open design on the body to circulate the airflow. 

As air mostly carries some invisible dust particles, they can easily get stuck on the fan blade when the fan runs. When the oven has been used in unfiltered air surroundings, there is much possibility of dust. 

If the dust or first particles are stuck on the fan blade, it creates load and Berdan on the fan motor which creates noise when the motor runs in load.  

  • Fan motor problem: As we know, a fan works when its motor rotates. If the motor has a problem when it rotates, you can hear some noise. 

Technically, this little fan motor cannot be repaired. It means if the malfunction is with the fan motor, you just have to replace it. It is not designed to be repaired. 

If the motor doesn’t make the sound when it rotates without the fan. It means the motor is okay. The problem is with its fan blades. In case the fan is broken, replace it.
