What causes blender to smoke?

I understand how disappointing it can be to find your blender smoking every time you try using it.

It had happened to me some years back, and I had to replace it as that was the only option in my case.

While you can fix some problems yourself, some will not have any proper fix, and replacement of the appliance will be the best thing to do.

So, let’s look at all the possible problems behind your blender giving a smokey or burning smell.

1. Leftover food

It is a common problem, especially if you don’t use the blender daily.

Sometimes, food material can get stored from the previous cycle and attach to the blades of your blender.

The blades become sticky and cannot function properly.

Due to this, the motor starts to get overheated, and you notice smoking.

Follow these steps if you think this is the problem with your blender:

  • Check the blades of your blender, especially the underparts, and check for leftover food particles.
  • If yes, clean the blender thoroughly with vinegar.
  • Do not leave your blender dirty after use. Clean it, rinse it, and let it dry after every use.

2. High voltage

High voltage can be very dangerous and can be the reason why your blender is smoking.

Most blenders are adapted to 120V.

However, if your power outlet uses a different or higher voltage, you should use an adapter.

If you haven’t been doing that, overvoltage might have harmed parts of your blender.

You can see smoke if the motor of your blender is burnt.

Avoid using the blender in such a case.

3. Gasket issues

Blenders don’t last you year after year, especially if you use them regularly.

It is not a problem, but this is how these appliances are designed.

So if you’ve been using your blender daily, the gasket will wear out eventually.

If you don’t know what the gasket is, it is the part that prevents ingredients from dripping into the coupler and motor.

If the food jams in the coupler or the motor, it leads to the smoking of your blender by causing electric short.

You will need to replace the gasket in such a condition.

How you replace the gasket will depend on the model of your blender.

You can take the help of the user manual or seek professional help to replace it.

But here are a few general steps, so you get an idea:

  • Take out the glass container and turn it upside down.
  • Wear gloves, so you don’t cut your hand.
  • Find the rubber seal.
  • Using a screwdriver, take the seal out of the container. Sometimes, the seal can stay stuck, and you might be unable to remove it. Heat some water and pour it on the seal. This will help you take it out easily.
  • Get the new seal and install it on the blade shaft.
  • After that, reassemble all the parts of the blender.

Test the blender by filling the glass container with water and leaving it for a while.

The water should not spill if the issue is fixed.

But, if this doesn’t fix the issue, you might need to buy a new blender or check if there’s any other issue.

4. Blade assembly issues

Either the blades or the bearing might be at fault and cause the smoking of your blender.

If the bearing is damaged, the blades will get imbalanced and fail to function properly.

To fix the issue, you might need to replace the bearing or the entire assembly.

The problem can also be with the blades of the blender.

The blades tend to get dull with regular or heavy use, so you must sharpen or replace them to keep the blender running without any fault.

Replacing the blades will depend on your blender model so check the user manual.

Here are the steps of how you can change the blade assembly or the blades on your blender:

  • Take the glass container out of the base.
  • Remove the container’s lid and turn the container upside down.
  • Hold the bottom part of the container and turn it in an anti-clockwise direction. This will help you detach that part from the blender.
  • Once you have access to the blades, you can replace them with new ones. Wear gloves, so you don’t hurt yourself.
  • Reassemble all the parts and try using the blender.

5. Overfilling the blender

Overfilling is a big no as it can damage your blender’s motor.

If you fill the blender to the brim, you will have a hard time closing the lid, and the blender will have difficulty rotating the blades.

This will cause the blender to overheat, leading to smoke coming out of it.

If you think you’ve been making this mistake, stop overfilling your blender.

You can clean the blender with vinegar to remove any food buildup.

This should fix the problem.

6. Faulty coupler

A coupler is that part of the blender which holds the container so it won’t get imbalanced.

If you overload the blender, the coupler will prevent the container from falling.

However, the couplers stop working when you overload the blender.

It can cause the smoke that you notice while using the blender.

If the coupler is damaged, you can replace it yourself.

  • Remove the blender container from the base.
  • Now using a screwdriver, lift the coupler from the base.
  • Keep doing this while turning the coupler every time.
  • The coupler will soon come out of the blender.
  • If you notice some threads on the motor, remove them using the screwdriver.
  • Now place the new coupler in place of the old one and screw it anti-clockwise.

7. Motor coil issues

A worn-out or defective motor can lead to your blender smoking.

Avoid using the blender, as using it in such a condition can make it explode!

Consider replacing the blender.

8. Faulty motor brushes

Damaged or weary motor brushes can cause the smoking of your blender.

You can find the motor brushes inside the base of the blender.

One easy way to identify this issue is if you notice sparkling inside the motor.

This indicates that the motor brushes are at fault.

If this is the case, consider seeking professional help.

9. Heavy and thick food materials

Ensure you are not using hard and thick food materials while blending, which puts an excess load on the blender.

This excess load can cause the blender to heat up and give out smoke.

Some food materials that people often use that overload the blender are:

  • Frozen fruits
  • Nut butter
  • Ice

Even if you need to put in these food items, use some liquid ingredients such as milk or water to avoid putting too much load on the blender.


Is it normal to smell smoke from the blender?

Many people reported getting a smokey smell from the blender when they used it for the first time.

It is fine if the blender is new and you are using it for the first time.

But, if you start getting a smokey smell or noticing smoke at a later stage, you need to inspect your blender and find the underlying cause.

Why did my Nutribullet start smoking?

A Nutribullet blender mostly starts smoking due to gasket or motor issues.

I have explained these issues in detail already.

If the gasket is at fault, you can try cleaning the blender or replacing it.

But if the motor is not working, you might need to replace the appliance.

There can be other reasons too that can cause your Nutribullet blender to smoke.

How do I fix my blender from overheating?

Since overheating leads to the smoking of your blender, you should understand how to use the blender the right way to prevent this from happening.

Here are a few tips to help you with that:

  • Avoid overfilling your blender.
  • Avoid putting too many thick and hard substances in the blender.
  • Clean the blender after every use, so food particles don’t get stuck anywhere.
  • Consider using an adapter if your electric outlet works at a higher voltage than 120V.
  • If the blender gets hot after use, let it cool down. Unplug it and let it cool down for 20-30 minutes before using it again.
  • Avoid using an overheated blender as it can cause an electrical short and even lead to the blender exploding.
