Top 10 Reasons A Ninja Blender Won’t Turn On And How to Make It Work

Wrong Assembly

If the blender is assembled incorrectly, then it would not work. This means, you will have to be careful in assembling it with its parts. We highly encourage that you always read the user manual that comes with your blender.

The Lid Is Not Locked Tightly

One of the main reasons as to why your Ninja blender would not work is that the lid of your blender is loose. Hence, do not forget to lock the lid whenever you are making smoothies and blending something. Keep in mind that the arrow down on the lid must be aligned with the arrow up on the arrow on the jar handle. By doing so, you would be able to ensure that the jar handle is properly locked.

Ninja Blender Lid Handle Stuck

When your blender’s lid handle gets stuck on the pitcher even when you use the release button, try to gently push the lid handle with your other hand and push the release button. If it does not work try to put your thumb on 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 is in place. Ensure that the part that holds the blades in place is not worn out nor is it jumpy. Try to use a strong screwdriver to loosen it off and tighten it back again.

The Pitcher Is Not In the Correct Position

Another reason could be that your blender’s pitcher is not correctly positioned. Try to rotate the pitcher into a locked position by removing it and putting it back again.

Blades Won’t Turn Properly

If this is the case, remove them and if needed, replace them with new ones.

The Ninja Blender Handle Won’t Go Down

If this happens, we suggest that you remove the handle of your Ninja blender jar. To do this just unscrew two small screws at the bottom of the jar under the handle. On the top of the handle push the little button and try to pry it. Put it back in properly. Ensure that the arrow on the handle would match the arrow on the lid.


Another reason as to why your Ninja blender does not work is that your blender has overheat. There are several reasons as to why your blender would overheat and one of them is due to overfilling your blender. Hence, as mentioned earlier, do not overfill your blender.

Internal Thermal Switch

When your blender overheats, the internal thermal switch would then turn off the motor of your blender until the temperature would drop back to its normal level.

Screeching Noise

This could be due to the pulsing air in the small space between blades and pitcher. It could also be due to your blender’s blades being stuck. Another reason could be due to your blender’s bearings being broken.

Internal Power Switch

Whenever your electronic power switch fails, we highly discourage you to fix it. In fact, we would recommend for you NOT to fix it yourself.

Tripped Breaker

Why Is My Ninja Blender Blinking White Light?

The reason could be that the container is not properly placed over the motor base. If it is not placed correctly and properly, a white light would keep flashing and would not run.

Ninja Blender Buttons Not Working

There is a possibility that the touchpad buttons of your blender would stop working. This is due to repeated usage. It could be that the membrane switch under Ninja buttons could be defective.
