This article will tell you what may cause your Ninja blender to stop working and how to fix it!

Why Did My Ninja Blender Stop Working?

There are a few reasons why your Ninja blender may stop working.

This may include:

  1. A build-up of food & dust in the bottom of gears/motor inside.
  2. A broken or loose wire.
  3. Having a cord that is too thin for the blender (using multiple extension cords).
  4. A lack of oil in the gears/motor (not running smoothly because there’s minimal lubrication).
  5. The pitcher being attached wrong or not on tight enough.
  6. A faulty switch or plug.
  7. It is possible that some features, such as the “pulse” button, are stuck on.
  8. The Ninja blender may have overheated from overuse and has stopped working for safety reasons. This is usually caused by adding too many frozen ingredients at once or processing for too long without a break to let it cool down.

How To Fix Ninja Blender Not Working Issue

1. Ninja Blender Stopped Working Due To Build Up Of Food Or Dust

If any dust/food is in the bottom of the gears or motor, try taking apart your blender and wiping it down with a damp cloth. 

Make sure to wipe off everything until there is no dust or food left in the gears so your Ninja blender will work properly.

2. Ninja Blender Not Working Because It Has A Broken Or Loose Wire

If the wire is broken or loose inside of the blender, you will need to take apart your blender and check if it has any visible wires that are broken. 

If there is a broken wire in your blender, you will need to contact customer service for replacement parts.

3. Ninja Blender Is Not Working Properly Because The Cord Is Too Thin

The cord on your Ninja blender should not be too thin for the appliance, as this could cause it to lose power while running and not start properly again once stopped (or stop working completely). 

To prevent this from happening, make sure you use an appropriate amount of cords when using multiple appliances at once with a single outlet. 

For example, using one heavy-duty cord for two or more appliances plugged in at the same time to prevent overloading and tripping on an extension cord.

4. Ninja Blender Stopped Working Because There’s Little Or No Oil Inside Of Gears/Motor

If there is not enough oil inside of your Ninja blender’s gears/motor, it will not run smoothly. 

To fix this, check if there is any oil in the gears by looking inside them (if you can see oily spots in either of your blender’s motors). 

If you notice that there is no oil at all in your blender, add a few drops of vegetable/mineral/coconut oil in each gear and turn the blender on the highest power setting for a few minutes. 

Repeat until you see an increase in oil throughout the gears (this could take 2-3 attempts).

5. Ninja Blender Not Working Because The Pitcher Is Attached Wrong/Not On Tight Enough

Make sure to double-check that your pitcher is connected properly and locked down tightly before turning on your blender, as this can cause it to not blend correctly or stop working completely. 

In addition, make sure that your pitcher is attached just right by checking if there are any gaps between where it’s supposed to attach and where it actually attaches. 

If you notice that there are gaps, adjust the two parts so they fit together better.

6. Ninja Blender Stopped Working Due To A Faulty Switch Or Plug

If the switch on your Ninja blender is faulty, it will not start when you push the button. 

To fix this problem, replace the faulty parts with new ones by contacting customer service or taking apart your blender and checking if there are any broken switches or loose cords inside that need to be replaced.

7. The “Pulse” Button On My Ninja Blender Is Stuck On/Not Working

It is possible for some features on your Ninja blender (such as the pulse function) to become stuck on after pressing a wrong button multiple times or accidentally touching something while blending. 

In either case, try turning off your blender and unplugging it from its power source for around 30 seconds before plugging it back in and turning it on.

8. Ninja Blender Not Working Or Spitting Out Liquid

If your blender is not working or spitting out liquid when you’re using it, there are a few simple reasons why this might be happening: the air gap between the lid and the container (or between blades) is too large, causing larger chunks to escape; further down toward the blade unit, food has collected around the blades; or lastly, there’s an issue with the motor itself.

9. My Ninja Blender Is Making A Loud Grinding Noise When I Turn It On

When a certain part of your blender is broken/grinding against another piece inside of it during use, this can cause it to make a loud grinding noise when turned on. 

To fix this problem, remove and replace the broken part by calling customer service or taking it apart yourself.

10. Ninja Blender Motor Is Too Hot/Is Not Turning On

If your motor is too hot to touch when you turn on your blender, it was most likely run for an extended period of time with a very low setting (or not started at all). 

This can cause the electric components inside of your blender to overheat, which often leads to malfunctioning or shutting down completely. 

If this is the case, try turning off your blender and unplugging it from its power source for around 30 seconds before plugging it back in and starting up again at a higher speed level.

11. Power Light On The Blender Is Not Lit Up

When the power light on your Ninja blender is off, it most likely means that it will not startup. 

If this is the case, check to make sure that the plug for your blender is in all of its respective sockets and the pitcher’s lid is closed correctly before turning it back on again.

12. My Blender Is Not Working And The Power Light Keeps Flashing On And Off

If your blender won’t start up or doesn’t stay powered on once you’ve started it, there are two possible reasons why: either a certain part inside of it has broken and needs to be replaced, or there has been an electrical issue somewhere along the line from where you’re using it to its power source (i.e. the power has been shut off or is unstable). 

In any case, call customer service or take apart your blender to see if there is anything that needs to be replaced before trying it again.

13. Not Enough Liquid

If your Ninja Pro Blender is not blending correctly and also making a loud noise when turned on, this may be because there isn’t enough liquid in the container for it to work efficiently (or at all). 

If you are using your blender for recipes with liquids such as smoothies and sauces, make sure that you put them in first instead of last so they can mix properly without just turning into a thick paste. 

14. The Base Of My Blender Is Hot/Is Not Turning On

If the base of your Ninja blender is hot, it was most likely run for an extended period of time with a very low setting (or not started at all). 

This can cause the electric components inside of your blender to overheat, which often leads to malfunctioning or shutting off completely. 

If this is the case, try turning off your blender and unplugging it from its power source for around 30 seconds before plugging it back in and starting up again at a higher speed level.

15. Blades Are Not In Place Correctly

When the blades are not in place correctly or are missing, it can stop your Ninja blender from working correctly. 

If this is the case, remove and replace them by calling customer service or taking apart your blender to see if anything needs replacing.

16. Blade Replacement Is Needed

Over time, your Ninja Pro blender’s blades may not work as well or may stop working completely. 

If this is the case, call customer service or take apart your blender to see if replacement blades are needed.

17. Water Has Been Added To The Container When Not Fully Disassembled

If you have added water to your container before it was fully disassembled without turning off the power and waiting for it to cool down first, this can damage the motor and cause your blender to stop working. 

To fix this, call customer service or take apart your blender to see if anything needs replacing.

18. Over Filling The Container

If there is too much liquid for what your Ninja blender can handle or if you have put in a lot of solids when blending liquids (or vice versa), it may stop working due to overflowing from the container. 

If this is the case, make sure that you only fill up at most two-thirds of it so there won’t be any issues. It will also help if you blend in batches rather than trying to do too much at once.

19. Too Many Hard Ingredients

If you’re trying to blend a tough or hard ingredient (such as nut butter), too many of them can cause your Ninja blender to stop working. 

If this is the case, don’t add any more than three tablespoons of it at a time and use the tamper regularly so that it doesn’t get stuck. 

Make sure that what you’re blending has been softened up beforehand and if none of this works, call customer service or take apart your blender to see if anything needs replacing.

20. Tamper Problems

Sometimes when using a tamper with certain recipes, it may not work correctly due to an attachment fault or something else completely. 

In either case, make sure that your container is locked in place properly/is in the right position for the tamper and call customer service or take apart your blender to see if anything needs replacing.

21. Broken Motor

If nothing seems to be helping, especially after checking all of the other reasons on here, your 

Ninja blender may have a broken motor which that will need to be replaced. If this is the case, call customer service or take apart your blender to see if anything needs replacing.

In some cases, your Ninja blender may be experiencing issues because of a faulty part. 

If this is the case, you will need to either remove and replace that faulty or broken part yourself by taking apart your blender or contacting customer service for further assistance.
