Are your Ninja blender blades not spinning? This is an incredibly frustrating problem that is slightly more common than you might think. If your Ninja blender blades are not spinning, you are going to need to do some investigating. Out of all the problems that can occur with a blender, this might be the most irritating.
You will know your blades are not spinning when the motor is turned on but nothing is happening inside the container. Without the spinning blades, your food and other ingredients will not turn at all, or they may turn very weakly. They definitely won’t be blending.
You may have an easy time blending liquids but your blades won’t turn when you add solid ingredients. There are a few reasons this could be happening, and some of them are easier to fix than others. If you have a serious issue with your Ninja blender, the best thing to do is reach out to customer service and they will likely replace your broken part.
Too Much Food
One of the main reasons why your blades will stop spinning is because you have overfilled the container. This may not be obvious right away, but if you try to empty the container a little bit and then blend again you may find that the blades are now spinning.
If there is ice packed beneath the blades, or if there is too much inside the container stopping the blades from beginning to spin, simply try to put less stuff into your blender. Remove some of the food chunks and then try to blend again.
The reason your blades won’t spin when you have overfilled the container is that they don’t have the room to start spinning. It’s like trying to push a wheel with a spoke through it. It simply won’t work. Your blades need enough room to start spinning before they can blend any ingredients.
For example, if you have a big piece of ice at the very bottom pushed against the blades, they probably won’t be able to spin. Your blender will make a very loud and angry groaning noise, which is the drive gear trying to spin but being unable to. Try to give the blades enough space so that they can at least start blending.
Not Enough Liquid
Another issue is a lack of liquid. If you have added too many hard ingredients into your Ninja blender and have not included any liquid, you may notice that when you turn on the machine the blades won’t spin. They’re trying to but they simply won’t. Either that or they will spin slowly and not work to blend anything. You will also hear an angry groaning sound from your blender.
This is because your blades need liquid to help them spin and break apart your ingredients. This is a very easy issue to fix. All you need to do is fill a little of your container with liquid. This will give your blades the lubrication and assistance they need to start spinning and chopping.
If there is nothing wrong with the ingredients inside your blender, and if your blades won’t spin even when your blender is empty, you undoubtedly have a mechanical problem. This is going to be significantly harder to fix. Not everyone can repair a blender on their own, and many of the parts may not be widely available.
The main issue for blades not spinning is that the threads have been stripped where your blades attach to the drive shaft. You see, the motor powers the drive gear, which turns the shaft that spins the blades. If any component is stripped, loose, or not working, your blades won’t spin.
Basically, your motor is running but something between the motor and the blades is loose. The threads can wear out over time so that there is nothing connecting your blades to the drive shaft properly. You can try to take the blender apart on your own to inspect the gray rubber gear. If it has stripped threads, you will know immediately. This will be the problem you need to fix.

Ninja Blender Blade Not Spinning: How to Fix
If the time has come to fix the internal components of your blender, you are going to need a professional. Even if it is just one screw loose, just a few threads that have been smashed flat and won’t allow the blades to turn, you will need to send your Ninja blender in to get some replacement parts.
There are no hardware stores that are going to sell replacement blender blade assemblies. It’s just not going to happen. You will need to reach out to your Ninja blender supplier and request a fix. Luckily, many Ninja blenders come with a pretty robust warranty, and so you won’t need to fix it yourself and you likely won’t need to pay for anything.
Of course, if you are exceptionally skilled at fixing small pieces of machinery and small appliances, you can try to fix it yourself. By disassembling the motor and looking at the drive gear, shaft, and by inspecting the pins and tiny screws that keep the entire assembly functioning, you may find something small that can be repaired.
However, you want to keep in mind that if you tear apart your blender you may never get it back together. And if you rip apart your blender and try to collect a warranty, you are probably going to end up paying more than you would have otherwise. In fact, if you rip apart your blender and can’t get it back together, you may be better off just buying a new Ninja blender.
As a final note, all the Ninja blenders are built to a very high quality of standards. If there is a mechanical issue stopping your blender blades from spinning, Ninja won’t have a problem replacing and fixing the part. This is a trustworthy company that has been building kitchen appliances for many years. I always trust Ninja with all my appliance and blender issues.
