Why Does My NutriBullet Have a Burning Smell?

If your NutriBullet has a burning smell its probably because the blender is overheating. The blade assembly consists of several parts – the sealing rings, sealing plate, the blades, and the bearings. Any of these components could seize while blending, which causes the other parts to work overtime and cause a burning smell.

There could be a variety of reasons why your blender motor and blades are overworking and causing a burning smell. It could also be because you are blending foods that are inappropriate for your blender type or are overworking the blender.

Whenever you smell burning, shut off your blender and figure out what’s causing the machine to overheat.


6 Reasons Why Your NutriBullet Blender Smells Like Its Burning

I’m going to quickly walk through the six most common reasons why your NutriBullet blender might smell like its burning. Thankfully, you can fix or prevent all of these super easily.

1. New NutriBullets need to be broken in

If your blender is brand new, you can expect the drive socket and blender motor to heat up during the first few times you use the machine. The burning smell is caused by the base windings and is most likely nothing to worry about. Use it 2-3x and this should stop happening.

If you do notice your new blender smelling, turn it off and let it cool back down. A burning smell is to be expected as you break in your new machine.

2. Blending frozen fruit or ice

NutriBullets aren’t really designed to be used like a normal countertop blender. They’re intended to be used for more personal use and blending up smoothies.

Most NutriBullets have a wattage between 500 and 1000. This is much less than Vitamix wattage, which is around 1500.

They have enough watts for a good blender, but not enough to break down hard frozen fruit or ice. If you’re trying to blend ingredients like those it might be the reason your NutriBullet smells like its burning.

3. Not enough liquid

NutriBullets are meant to be filled with liquid along with whatever food/ingredients you want to blend up. This helps the blades moved quickly through the food so that they can get blended easily.

If you don’t use enough liquid then you might have a hard time blending up your food causing the NutriBullet to smell like it’s burning.

NutriBullet also advises you to not use hot liquid or carbonated beverages in their blenders.

4. Blending for too long

When you run a blender for too long it can start to overheat. That’s why NutriBullet recommends running their blenders in 60 second bursts.

You shouldn’t be blending anything that takes longer than that, but if you need more time, then let your blender rest for a minute before starting again.

You shouldn’t blend for more than three, 1-minute long sessions.

5. Overloading the blender

All NutriBullet blenders have a max capacity. Take a look on your container and you’ll see the max line on the blender jug.

If you overload your blender with too much food, it can cause the blades to slow down and be overworked. This will make your NutriBullet have a burning smell.

Avoid overloading the blender and you’ll be good to go.

Fill the cup to the max line or no more than 2/3 full

6. Worn out parts

Although most blenders should outlast the standard warranty period of one year, if you use it several times per day, it may not last as long. If you’re continually smelling burning coming from your blender, it could be a sign that the machine is being overused.

Over time, parts of the blender will begin to wear out. The blender blades won’t be as sharp, the motor won’t run as fast, and the ring might start to wear out.

This might be a sign that it’s time to get a new blender! If you’re still under warranty, then reach out to NutriBullet for a replacement.


How to Maintain Your NutriBullet Blender and Prevent a Burning Smell

On top of making sure that your blender isn’t overworked, it’s important to maintain your machine accordingly when not in use.

The best way to maintain your blender is to clean it every time you use it.

When you’ve finished using your blender, clean out the contents as best you can before filling it halfway with warm soapy water. Put the lid on and start the motor at a low speed. Gradually increase the speed over a minute, before rinsing out the blender with warm water.

The other key is to always remember the best practices we mentioned above:

  1. Use liquid
  2. No ice
  3. 60 second bursts
  4. Don’t overfill it
