How To Fix Ninja Blender That Is Not Working or Won’t Turn On

Ninja blenders are popular because of how effective they are at blending. The sharpness of the blades and the speeds at which they move are what make Ninja blenders work so well. They also are what can make them dangerous if you don’t use the blender properly. That’s why Ninja has programmed many safety mechanisms into its blenders. If your Ninja blender won’t start, is blinking red, or is not working, it is likely that you have tripped a safety mechanism. Keep reading to learn more about the most common causes, including the lid that won’t close and a pitcher or lid that won’t lock, and how to fix them.

Ninja Blender Not Working Cause #1: Pitcher Is Not Installed Correctly

If the your Ninja blender is on but won’t start blending, it is possible that your pitcher is not securely on the base. This is a common mistake that is easy for new Ninja blender owners to make. Simply placing the pitcher onto the motor base is not enough. You need to lock it into place.

To lock your Ninja blender pitcher into place, align the pitcher so that the handle is slightly to the right of the word “LOCK” on the motor base. Place it down and then rotate the pitcher clockwise until it clicks into place. You should be able to hear this click. However, you can also confirm that you have locked it by pulling up on it gently. It should not move. The the available program buttons should light up if it is locked. Your blender is now ready for use.

Ninja Blender Not Working Cause #2: Lid Won’t Close

Your Ninja blender may also not be working if the container lid is not installed properly. When placing the lid on the pitcher, make sure that you line up the triangle symbol on the lid with the triangle symbol on the handle. If these symbols don’t line up, the lid won’t lock. To complete the lock, press down on the lid handle until it clicks into place. Don’t forget this last step! Lining up the triangles is not enough. Your Ninja blender won’t work if you have not lowered the handle to lock the lid into place. The lid handle will not fold down unless you attach it to the pitcher container correctly.

If you are not able to lock the lid on your Ninja Professional or Ninja Foodie, it is possible that the you did not install the blade assembly correctly. If you don’t fully seat the blade assembly with a loose fit onto the drive gear inside the pitcher, it will sit a bit too tall and prevent the lid from locking. You should not add any ingredients to the Ninja blender until you insert the blade assembly correctly. If you added ingredients first, you’ll need to remove them and then add the blade assembly. Make sure nothing remains in the container that may jam the blade assembly connection. If you see any stuck on ingredients that may be interfering with the blade assembly connection, clean the blade assembly and pitcher in the dishwasher.

If your Ninja blender won’t start or stay on after having just used your Ninja blender, it may have overheated. In this case, you should turn off the blender, unplug it from the electrical outlet and let it sit for 15 to 30 minutes to cool down. Remove the blade assembly and empty any contents from the pitcher. This will help to ensure nothing is jamming the blade.
