Why Is My Blender Smoking? The Correct Answer Is Here!

You expect your blender to make delicious, nutritious smoothies. But all you get is smoke and smell something burning suddenly. So what’s going on?

If you’ve noticed that your blender is smoking, it may be for several reasons. We will cover them in this article. So let’s read on to find out, “Why is my blender smoking?”

9 Reasons Why Your Blender Is Smoking?

There are many reasons why your machine is smoking, such as thick ingredients, overfilling, faulty blade assembly, food leftovers, weary gasket, and a worn-out coupler.

1. Thick ingredients

Avoid using your machine to blend your thick ingredients, such as nut butter, as it can overload the motor. Also, frozen fruits and ice in smoothies can put an extra load on your machine’s blades, resulting in the same thing.

We recommend always using pulse mode to blend heavy food. Also, you can put some liquid, such as milk, juice, or water, to thin your mixture.

2. Overfilling

Every blender jar has a limit on the ingredients you can put into it for each blending. 

Hence, if you insist on filling its container up to its lid, it will have to struggle to blend it all, leading to its motor overheating. In this case, smoke will come out from your blender base.

So if you want to minimize any severe damage to your blender, it’s essential to put slightly less than 3/4 of the ingredients inside your blender’s container per blend.

3. Faulty Blade Assembly

Once a bearing gets damaged, it will make your machine’s blades wobble. In this case, these wobbling blades will not be easy to run smoothly.

These blades can then be misaligned, damaging the plastic around them. When these blades rub against hard plastic, it can also create a screeching sound and cause smoke and a weird smell.

If that is the case for you, replacing the damaged blade assembly is essential.

4. Food leftovers

If you do not use this machine regularly, material and ingredients from the previous use may stick to its blades. As a result, these blades will not rotate freely, leading to overloading the motor and starting smoking.

So, after each use, it’s wise to soak your blender’s blades in white vinegar for several minutes before rinsing it with clean water and letting it dry.

5. Weary Gasket

Your machine’s gasket will prevent your ingredients from leaking to the motor base and coupler. So if you use your blender regularly, its O-rings or gasket can wear off quickly over time.

When your ingredients spill from the jar, they will start sticking inside the motor casing and under the coupler. Then, the coupler will likely jam, leading to a smoky blender.

6. Worn-out Coupler

The drive coupling is below the blade assembly, which is the rubber gear shape component. These couplers will connect your machine’s motor to its blades. Unfortunately, after a while, they may deteriorate.

Also, the friction between loosely coupled components may cause smoke and a burning smell. If your machine’s coupler is in bad condition, replacing it with the new one is essential.

7. High Voltage

In most cases, blenders work on 110-120V (in the US). Alternatively, it can also be 220-240V (for Sweden or the UK). 

There is no denying that overvoltage can cause damage to your blender motor. 

Then, your machine’s motor may be burnt, causing smoke from your blender.

You should have an adapter if the voltages on your power socket and your blender are different.

8. Worn-Out Motor Brushes

You will find two carbon brushes inside the base and around your machine’s motor shaft. If these brushes are damaged, you may end up with a smoking blender.

So if you detect any sparking along with the smoke inside your motor assembly, it’s the brushes.

In this case, all you need to do is call the support or get help from a skilled electrician to repair it.

9. Burnt Motor Coil

When you detect smoke from the motor’s bottom vent, it could indicate that the motor coil has been damaged. 

If you continue to use your blender, it will degrade insulation and may result in an electrical short. So we recommend stopping utilizing the unit immediately in this case.

Blenders have been known to explode due to:

  • Improper closing of the lid
  • Overheating

These causes are mainly a concern with older models as most modern ones, including those built by Ninja, now come with safety features that preclude these cases from being created.

2. Why Does My Nutribullet Smell Like Burning?

A burning smell coming from a Nutribullet may indicate a problem with the gasket.

If you blend for so long or do not add enough water, it will put too much pressure on the gasket. It should get hot and begin to smell like burning rubber.

3. How Can I Keep My Blender in Good Condition?

You should deep clean your blender each use if possible. If you’re busy, doing a deep clean after a few uses is okay.

Besides, you should not overburden your blender motor by blending hard content and ice. 

Last but not least, read your owner’s manual and follow the instructions from the manufacturer to use your machine.
