Ninja blender not working: Troubleshooting Ninja blender problems
Ninja blenders are one of the most versatile blenders on the market.
They’re also less expensive as compared to their counterparts, which means they are not super high-quality products and may not work for some time.
If you have had trouble with your ninja blender not working, there is no need to worry!
We’ve created this article for troubleshooting and fixing ninja blender issues.
How does the ninja blender work?
Before jumping into the issues, you must keep one thing in mind if you are new to Ninja blenders.
They are a bit complicated to use at first.
The assembling involves a bit of complexity. You will have to lock Lid through a proper mechanism before it could work. The pitcher would also need to click in place over the base or else you will not be able to work a Ninja blender.
The reason for all this fail-safe running is the unique stacked assembly of very sharp blades. The blades MUST not rotate with an open lid.
Most of the issues users face are likely due to improper assembly. But we have covered almost every issue you could possibly face while using a Ninja blender. So, give it a read.
Why won’t my ninja blender work? My Ninja blender stopped working.
There could be many simple or complicated reasons why the ninja blender won’t run. But you can easily fix ninja blender by following this post.
The simplest situation where a Ninja blender wouldn’t turn on is when the cord is not plugged into an electric socket.
Not plugged in
If your Ninja blender won’t start, check the power source first. This may seem an obvious step but usually, the plug is either loose or there is some issue with the socket that you may not be aware of. Try changing the power socket.
Tripped circuit breaker
This problem is also related to the power source to which the blender is being attached.
If for any reason, the circuit breaks and you do not get any electric power to your blender, it won’t work obviously.
Faulty power cord
Another reason that is hard to judge is a fault in the power cord. Your power plug could be working fine, and there could be no issue with the motor and the blender itself. But the cord may get damaged and may not supply electricity to the motor to run.
If you haven’t dealt with any electric equipment before, we suggest you take your blender to the repair service or the manufacturer to look into the issue.
The Ninja blender blade stuck
Another common problem that Ninja blender users face is having the stacked blade shaft stuck.
The issue occurs when you do not use your ninja blender regularly, or if there is some gunk left from previous blends.
The blade may also get stuck when you put it wrong and push it way harder than normal.
Overfilling blenders is dangerous and one of the main reasons why Ninja blender wont work. It results in many problems including stuck blades and overheating. Never fill the blender above recommended max level. Never put these items in your blender either.
Ninja blender broken
Ninja blender has many smaller components that need to work for Ninja to work.
If any of these components break, the blender is rendered useless.
These components are the little pins on the handle and at the bottom of the pitcher. The one on the handle is pushed by the lid and it then pushes the switch at the bottom below the pitcher and runs the blender.
In case these parts break you will need to replace the pitcher. As these parts are all connected to the Pitcher only.
In rare cases, the motor of the Ninja blender may burn out. Some people try to repair it at home but it is better to let a professional technician do the job for you.
My Ninja blender turns on but won’t blend.
When troubleshooting the Ninja blender that is unable to blend. You will sometimes come across situations where the blender’s power will be on but it won’t blend. Or even if the blades are turning, the products won’t blend well enough.
A few reasons for this are already covered above, but there is more to it.
Top 10 Reasons a Ninja Blender Won’t Turn on And How to make it work
Ninja Blenders do not work when the parts are not assembled correctly. Therefore, you should always be careful when assembling these parts. Always read the user manual that comes with the package before using the blender.
The lid is not locked tightly (the ninja blender top won’t close)
A loose lid is one of the main reasons why ninja blenders are not working.
If you are making smoothies or blending anything, don’t forget to lock the lid of the ninja blender tightly. The arrow (🔽) on the lid must align with the arrow (🔼) on the jar handle to lock properly.
Ninja Blender Lid Handle Stuck
If the Lid handle is stuck on the pitcher and won’t come out with the release button. Try a gentle push on the lid handle with the other hand and then push the release button.
If nothing works out. Put your thumb in the spout of the lid and put some pressure to pop the lid open.
Loose Blade assembly
Check if your ninja blender’s blade assembly that holds the blades in place is not worn out or jumpy. It could make the Ninja blender leak.
It would be best if you had a strong screwdriver to loosen it off and tighten it again firmly. If you issues like your Ninja bullet not working, here is a video of how to troubleshoot and fix a NutriNinja.
For other Ninja blenders with stack blade assembly, make sure it is upright and seated properly on the drive coupling. If it is a little loosely seated, don’t worry.
The pitcher is not in the correct position
The pitcher of the blender should fit onto the base in any position.
If it takes more effort to rotate the pitcher into a locked position, remove it and put it back again. It should rotate on the base with minimal effort.
Blades won’t turn Properly
The blades of the Ninja blender are easy to remove if they are not working properly. You can replace them with new ones. But, sometimes they stick inside the socket. This issue is caused when there are some hard pieces of food chunks blocking the blade assembly.
The residue from previous blends dried out on the drive gear can also be the reason for jammed blades.
There may be some metal pieces causing the sound and disrupting the blade’s rotation.
The ninja blender Handle won’t go down
You can remove the handle of the Ninja blender jar for various purposes.
Unscrew two small screws at the bottom of the jar under the handle.
On the top of the handle there is a little button, push that button and pry the handle cover with a wedge.
There is an arrow on the handle that should match the arrow on the lid for a proper fix.
The handle should be in the right or left corner of the blender. It will not turn on if the handle is not positioned correctly.
Another reason could be that there are little chunks of stuff stuck inside, which can overburden the motor. Blending hot liquids for too long can also cause this problem.
Overfilling the blender jar with hard and thick ingredients can also cause overheating. The result can be smoking or even burning of the blender motor.
Thicker blends will make the motor work harder than needed, thereby causing an overheating situation.
Also, make sure to place the blender in a neat and dry space for proper airflow through the motor assembly in the base.
Internal thermal switch
During prolonged use or overburden, the blender’s internal thermal switch detects overheating.
It switches off the motor until the temperature drops back to the normal level.
Thus, you can use the blender without any issue when the temperature is again normal.
This could be either because of pulsing air in the small space between the blades and the pitcher or a stuck blade issue.
In personal blender models like Nutrininja, the bearings of the blade assembly may also break.
Broken bearings or worn washers make the blades wobble and result in weird and loud noise.
Internal power Switch
The electronic power switch under the on-off button can sometimes fail.
If this is the case, DO NOT try to fix it unless you are fully skilled in electronics, you should claim the warrant if you can still.
Loose connections and wiring can trip the circuit breaker.
So first, check connections/wiring by turning off both the main switch and circuit breaker and then looking for loose wiring.
If everything is okay, reset the breaker setting and try running the blender.
Ninja blender power light blinking
If the blender’s power light is blinking, it means that your blend pitcher is not in the correct position or there is a problem with the lid.
At the bottom of the pitcher, there is a pin that goes up and down with the lid handle. This pin pushes a switch on the base. If the switch is not pressed the power button light will keep blinking and the blender will not run.
Why is my ninja blender blinking white light?
This could be the case in Nutri Ninja blenders where you need to fix the container properly over the motor base.
Otherwise, it will keep flashing white or red light and wouldn’t run. Ninja blenders are too picky about putting the Lid and the Pitcher. So, make sure everything is placed correctly.
Ninja blender buttons not working
Most products like Ninja Professional blender, Ninja Duo and Ninja Mega Kitchen System have touch pads on the control panel with soft push buttons. Some advanced versions have pure capacitive touch panels.
The touchpad buttons may stop working with repeated usage. The issue could be with the membrane switch under the buttons.
The membrane switch has soft touch electrical switches with a certain conductive coating on them which can go defective.
Another reason which can affect both membrane switches and touch screens are failed circuits inside the base. This failure could occur due to liquid leakages from the blender jar or exposing the base to water.
Do not try to fix such an issue and contact repair services.
The ninja blender extract function not working
The extract function is an AutoIQ preset. If this function is not working, you might be using it for an invalid food item. Each AutoIQ preset is supposed to work for certain kinds of food items only.
Is there a reset button on a Ninja blender?
No, there is no reset button on Ninja. If it stops due to the thermal switch off, you will need to unplug the blender and power it again after a minute or two… This is how reset works on Ninja blender.

Could you please help me? The blade in my Ninja food processor/ blender is stuck! It works perfectly fine but I can’t take the blade out. What should I do?
Hi Linda. I am sorry for replying late. Has your problem been solved? If not, please tell me which model are you using? Is it blade assembly stuck to the drive socket? technically it should not happen, because as you would already know the blade assembly is set loose. But either the grooves on your blade assembly are damaged or there are some residue ingredients that jammed your blade assembly. You should try to hold the drive socket from the bottom of the food processor container or blender jar and give a turn to the blade assembly manually. It should unstick it. Please share your feedback thank you.
“Ninja Blender Power Light Blinking” This section put me right on the problem. I went straight to the area that the top clicks into and found that the protrusion was broken off. The cylindrical pin was still in tack. But what helped me the most was: “At the bottom of the pitcher, there is a pin that goes up and down with the lid handle. This pin pushes a switch on the base.” Voila!!! Problem found. Need to get a new blend pitcher. Thank you very much. This website was very useful. We have the NINJA KITCHEN SYSTEM AUTO-IQ; MODEL # BL681A Thanks again
Hey Ron, I am so glad it helped. The problem is unfortunately beyond repair. Good luck with the new pitcher. Happy Blending!
My rotater are stuck and won’t turn please help!
Hi Johanna. Can you please tell us which model you have? So that we could guide you further. Thank you.
my blender starts, then stops. pulses only
Hi Ricki, Thanks for the comment. Sorry to hear about your problem. What model do you have? And what settings are you using for blending?
I just took delivery on the Ninja BL 400c and it’s dead due to none of the buttons work!…..There is two little bars of light that light up when you press the on-off button……and that’s it!!…..Can the unit be repaired and where could I send it?……Thank you for your time Dennis
Hi Dennis, Thank you for your comment. Sorry about having the problem (and replying late).
Your blender is not dead. No need for repair or return. The white bars are blinking because the blender is not assembled properly.
Fill the Cup with whatever you want to blend. Fit the blade assembly.
Put the blender cup with blade assembly onto the base and turn it clockwise until it clicks.
The white bars — will change to 00 which means the blender is assembled properly.
Now, press the smoothie button or any other button and it will start blending. Stay blessed and Happy Blending!
Hi, can someone help me. my blender was working just fine, until I started using the Nutri Ninja Cup. Now that I want to use my regular blender is does work. I put it in the lock position and does not turn on. The light on the Nutrient & Vitamin Extraction is on, but does not blend. So I have to remove the blender and put it back but not all the way why it locks, it works. What should I do please?
Hi Daniela, Can you please tell us which model?
You have stated that your main pitcher does not work when you fully lock it into position.
It does work when you do not turn it all the way on the base? This might be the problem with the switch on the blender base. This switch activates from a pin at the bottom of the large pitcher when you lock it onto the base. There could be some misalignment in the positions of the pin (at the bottom of the pitcher), and the switch (at the blender base).
I have already mentioned all the details in the article with pictures. But, if you still have a problem, you call directly to Ninja customer support at 1-800-365-0135.
Products lead out the bottom of mixer.
That would be a seal issue on the pitcher or smaller attachment and shouldn’t be too hard to replace yourself, if by the bottom of the mixer you mean the attachments which would be the obvious place you’re describing
The pitcher attachment with lid placed and locked properly won’t activate the motor. The smaller attachment works fine. I tried depressing each switch by themselves, then both switches that are activated by the pitcher tab, but it doesn’t work in either scenario. The light never stops blinking. There are two switches on this model 1100. It seems that both switches are bad. Will Ninja cover this repair? It’s brand new.
If it is under warranty, Ninja will have to repair it. Please call their customer support at 1-800-365-0135.
I have the SS400 Ninja Ultimate. All questions I read are about the Blender pitcher. My problem is with the smaller smoothie maker. I have used the Ultimate without problem until now. For some reason the smoothie maker base will not sit down far enough into the blender base for the plastic tabs to slide into their slots so that I can use it. I am stumped. Any ideas?
I will send you guide how to fix please share you mail.
