Ninja Blender Smells Like Burning? Top 8 Reasons Here

Last Updated on May 19, 2023 by River Tree Farms

Have you noticed a burning smell coming from your Ninja blender? It isn’t only annoying but also a sign of possible damage. Ninja blender burning smell usually results from hard items like ice. They increase the risk of Ninja blender smoking and damage to body parts. Ice and other hard substances can dull your blades and put unnecessary stress on your motor. If your Ninja blender smells like burning, here are a few potential problems and their solutions.

Ninja Blender Smells Like Burning | Reason:

Ninja Blender Smells Like Burning

1. Blending for too Long

If your Ninja blender has been working for too long, it may produce a burning smell. Ninja blenders are ideal for making quick smoothies. If you use them for prolonged periods, you are likely to run into problems.

The blades of your blender will overheat from the friction, especially when blending frozen fruits or vegetables. The solution is to let your blender run for about three minutes and give it a break. Turn it back on when it has cooled down. Stopping your machine every few minutes can prevent blender motor burnout.

2. Blending With No Liquid

Add some cold water to your blender jar when making smoothies. Avoid hot water as it could increase the temperatures in your blender and cause an explosion. With water up to the max line, the blades will spin, and there is minimal risk of the motor overheating.

3. Worn Out Parts

If you notice the smell of burning rubber from your blender, it is probably the result of worn-out parts. Check your rubber seal, blades, and motor. Any part of your blender that spins can malfunction and cause bad smells. Even the most powerful motor will malfunction at some point.

Fortunately, fixing the worn parts is pretty easy a professional should help you find high-quality parts. You can then get back to making your favorite smoothies without having to worry about foul smells. If, however, your motor is burned out and it was a cheap blender, replacing it makes more sense.

4. Failure to Clean the Blender Jar

Pay attention to the smell coming from your blender. Is it really a burning smell? Sometimes, your blender will retain the strong smells of garlic, onions, and other strong-smelling ingredients.

You can get rid of that smell by cleaning the blender thoroughly after every use. Pay attention to the blades and gasket as the gunk can stick to them. Use hot water and mild dish soap to remove strong smells.

5. Old Brushes

If the motor brushes on your blender are worn out, you may notice a strong burning smell. The brushes arc over time and may even produce some smoke. The carbon brushes that electric motors use transfer electricity to the armature. When these brushes are old, they can no longer come in contact with the armature.

Unplug your blender and replace the brushes. It is a simple process, and all you need to do is follow the owner’s manual. Ensure that your brush fits perfectly into the motor for efficient functioning.

6. Overloaded Blades

If your blender blades are overloaded, they could damage the couplers. Blender couplers come in various materials and shapes. While some can withstand more than others, they generally melt when the blades are overloaded. Sometimes, plastic couplers harden and overload the motor resulting in a burning smell.

The solution is to unplug your blender and replace the coupler. It is at the top of your blender base, and it easily pops out with a screwdriver. Avoid overloading your blender blades in the future to prevent possible problems.

7. Faulty Motor

When other parts of your blender are faulty, there is a high chance that they may also affect the motor. The result is a foul electrical smell that doesn’t seem to go away. If the seal of your blender is torn, it might allow liquid to get into the motor.

To preserve the integrity of your blender motor, do not blend ice or hard substances. In addition, you should replace the motor brushes when they get old.

8. Worn Rings and Gaskets

A lot of fluids go into your Ninja blender. It, therefore, makes sense that there are mechanisms to keep liquids away from the motor. Everything has to be sealed properly. This includes the sealing rings and the gaskets.

Unfortunately, the rings and gaskets wear out and crack with time. If they aren’t replaced, you may have liquid getting into the wrong places. Luckily, you can easily identify this issue.

Remove the blade assembly and take a look at the seals surrounding the blade. If they appear to be frayed or flimsy, you need to replace them. The seal between your blender jar and agitator assembly is one of the most significant ones. Pay attention to it.

Simple Tips to Care for your Ninja Blender:

Caring for your Ninja blender is easy. It could save you a lot of money and the headache of damaged parts. The most important tip is to follow the user manual strictly. When in doubt, always refer to it for guidance.

Clean it with warm soapy water after use and ensure that nothing sticks to the blades during storage.

If, when you turn the blender, there is a humming sound, but the blades won’t turn, reduce the load. Overloading your blender could damage the blade and motor. If anything appears to be jamming the blades, remove it carefully. Replace worn-out parts in time and get a professional opinion when you need it.


If your Ninja blender smells like burning, there are a few possible problems. While the smell is alarming, it isn’t impossible to fix. Common causes include leaving your blender on for too long, blending with no liquid, overloaded blades, and a faulty motor. Even though your motor can be fixed, there are instances when replacing the entire blender is a better idea. Get a new blender if the cost of repairs is unreasonable. Take care of your Ninja blender by cleaning it often and replacing worn-out parts. Avoid blending ice and other hard items.
