How to Turn On a Ninja Blender (5 Reasons it Might Not Be Coming On)

So you just got yourself a brand-new Ninja blender? Congrats! What you’ve got there is one quality product. Before you go on to making your favorite dishes with this blender though, there is just one little bit of a problem to address; how to turn on a Ninja Blender. 

If you have ever used a Ninja Blender before, you’d agree that these blenders can be a bit intimidating the first time you try to use them. With their many buttons and complicated-looking setup, it’s no surprise first-time users often have trouble turning these blenders on in the first place. Well, it’s nothing to be ashamed of. We’ve all been there, and thankfully, it gets better! 

This article will help get you on the way to using your Ninja Blender and make sure you never need to ask the question “how to turn on a Ninja Blender” again!

How to Assemble a Ninja Blender

Since most people who want to know how to turn on Ninja Blenders are fist time users who just got a Ninja Blender, it’s important to first address how to assemble a Ninja Blender. This only takes a few steps:

Step 1 – Place the Pitcher

Place the empty pitcher on the motor base so that the edges form a diamond above the motor base. When done correctly, the pitcher handle should face out to the right of the motor base.

Step 2 – Lock it in Place

Once the pitcher is on the motor base, twist it clockwise until you hear a click which indicates that it has been locked into place. 

Step 3 – Carefully Place in the Blades… CAREFULLY!!!

Once you have locked the pitcher onto the base, it’s time to place the blades in. Carefully place the stacked blades into the pitcher on top of the blade gear. Be careful when doing this. Those blades are quite sharp; Ninja sharp! Make sure you hold the blades at the top of the shaft, so you don’t cut yourself. Avoid the sharp, pointy sides at all costs.

Step 4 – Seal the Deal with the Lid

With the blade assembly in the pitcher, the final step is to place the lid over the pitcher. Ensure that the arrow on the lid is correctly aligned with the arrow on the pitcher handle. You assemble the blender correctly if the pour spout is directly across from the handle. Once your lid is firmly placed over the pitcher, lower the handle on the lid and push down firmly until you hear a click, indicating that it has been locked in place.

To know if you have arranged the pitcher correctly, click on the power button and check to see if the red light on the power button is solid. A flashing light on the motor base means that the pitcher isn’t properly aligned with the motor base. Check to ensure the lid is firmly attached to the pitcher and the pitcher is locked to the motor base. 

Now with that over with, let’s get to actually turning on the Ninja Blender.

How to Turn on a Ninja Blender

Despite the complicated-looking setup of Ninja Blenders, they are actually not that hard to set up and can be done in 3 simple steps.

Step 1 – Plug in the Blender

Of course, this is the first step. Without that much-needed juice, your blender is never turning on.

Step 2 – Click the Power Button

The power button on Ninja Blenders (which are sometimes labeled START/STOP) offers a number of different functionalities. This button not only prepares the blender for work but also tells you when the pitcher is properly attached to the base motor. 

On clicking this button, the display at the top of the motor should turn on. If the display shows solid colors, the pitcher is on right and the lid has been closed properly. If the display blinks, however, you’d need to reassemble the blender. 

If on clicking your blender, the display colors are solid, then your blender is turned on and ready for use!

Step 3 – Start Blending

Once the blender is turned on, all you have to do is start blending. Depending on the type of Ninja Blender you’ve got, your Ninja Blender might come with a series of preset programs pre-installed on your blender. Blenders with such preset programs would often have buttons like Smoothie, Ice Crush, Chop, and so on. All you need to do is choose any of the preset programs and your blender will automatically go to work and blend on. Each preset program is time-based and would turn off automatically. You can also manually blend with the Low, Medium, High, and Pulse buttons.

If your Ninja Blender doesn’t come with any preset programs, you can simply blend with any of the Number or Low, Medium, High, or Pulse buttons depending on your needs.

Reasons Why your Ninja Blender Wouldn’t Turn On

Sometimes, the problem isn’t that you do not know how to turn on your Ninja blender, but that the blender is just not turning on. Here are a few reasons this might happen.

  1. Your Blender isn’t Assembled Properly

This is the most common reason. If either your pitcher or lid isn’t locked into place properly, your Ninja Blender wouldn’t turn on. Reassemble the blender and that problem should be fixed.

  1. Over Stuffing

If you look closer at your pitcher, you will notice a mark indicating the maximum level of ingredients and liquid that should be placed into it. If this mark is exceeded, your blender will not turn on. If you ever need to blend more than what the blender’s maximum limit permits, simply blend in batches instead of over-stuffing the machine. 

  1. Overheating

Another reason why your Ninja blender may not be working could be due to heat. If your blender is hit to the touch, then it wouldn’t work. This is because there is a safety device built-in with the blender that shuts it down whenever it gets hot.

Fixing this is not difficult. All you need to do is let it rest for a while; about 15 minutes of rest would do the trick. Afterward, turn it on again. Your Ninja blender should be working fine this time.

  1. Particles in the Base

This is also a common issue with Ninja blenders. If the blender doesn’t turn on, it could be because tiny little particles have found their way into the base of the blender. The Ninja blender is designed not to work if particles get into it like this. 

Before turning it back on, disassemble the blender and clean the base properly. Once you’re done and it’s satisfyingly clean, you can try turning it on again. A note of caution, though; do not use water to clean the motor base. Try blowing out the particles that may have gathered, or use a tiny pick or other utensils to scoop or gather any particles that refuse to move. 

  1. Faulty Parts

Like all appliances, your ninja blender will not last forever and is bound to develop some fault or the other. If you have tried out everything on this list and your blender still isn’t turning on, chances are, the blender has developed some fault. Unfortunately, when this happens, fixing the blender is better left to professionals. Thankfully, Ninja Blenders are some of the most reliable blenders on the market, so you’d almost never need to worry about this!


The secret to how to turn on a Ninja blender isn’t as complicated as many first-time users think. It all takes simply assembling the blender properly, clicking the power button, and blending! If despite having done all that, your Ninja Blender is still not turning on, then it’s probably for one of the 5 reasons mentioned above. Fix those and you should no longer have any problems!
