Ninja Blender Lid Won’t Lock – How To Fix?

Ninja blenders are all the rage. They’re convenient, they’re powerful, and they make quick work of crushing ice cubes, blending smoothies, or whipping up a batch of pesto sauce in seconds flat.

But like any blender, they can have their problems. One common issue is that the Ninja blender lid won’t lock on to the pitcher.

This can be a nuisance, but it can also present a safety hazard.

Luckily, there are several ways to solve the problem.

Ninja Blender Lid Won’t Lock – 5 Reasons And How To Fix Them

1. The Blade Assembly Is Installed Wrong

If you are facing the problem of your Ninja blender lid not fitting correctly, it is possible that you have unknowingly installed the blade assembly in the wrong orientation, which can happen even if you have been using the blender for some time without any trouble.

To install it properly, take hold of the rubber gasket with your thumb and forefinger and then press down on top of the blade assembly until you hear a clicking sound.

In some models, the blade assembly may have two prongs instead of a click; these should face the back of the pitcher when inserted properly.

Make sure to twist the blade assembly completely in a clockwise direction so that it locks firmly in place and points straight down from inside the pitcher.

2. The Blade Assembly Is Cracked Or Worn

In the event that your blender appears to be functioning correctly, but the blade assembly continues to refuse to lock in place, it may be due to the rubber gasket being worn down over time, causing it to lose its tight grip and prevent the lid from closing securely.

Fortunately, you can quickly fix this issue by purchasing a replacement kit and replacing the worn-out rubber gasket. Alternatively, you can opt to wrap a rubber band around the lip of the jar and under the spot where the cap attaches to it, which adds just enough give for the blade assembly to fit snugly on top of it without causing any damage to the blender.

3. There’s Still Something In The Jar

The problem of the blade assembly refusing to lock in place is more likely to occur if you have recently blended something and have not yet had the opportunity to clean out the jar.

To prevent this from happening again, it is advisable to wash the jar thoroughly after each use or at the very least rinse it with warm water until all remnants of whatever you blended have been removed from the interior walls.

4. Your Blades Are Bent Out Of Shape

Suppose your blades are performing well but fail to lock into place correctly; it’s plausible that they have become distorted or bent due to impact.

To rectify this, you have a few choices. Start by trying to remove the blade assembly and bend the blades back carefully by hand.

If that doesn’t work, another option is to clip off the bent segment using a pair of scissors or small pliers to make them straight again.

Alternatively, if the blades are significantly worn down, it may be time to replace the entire blade assembly.

5. You Dropped Your Blender and Bent Something Out of Place

Resolving the issue of a Ninja blender lid that won’t close is perhaps the most complex because it requires disassembling the blender down to its core components.

You can either carefully follow the instructions in your owner’s manual or search online for guidance if it is not available.

If you decide to proceed, begin by removing and emptying out the jar.

Then, unscrew all the visible screws on the base and pry off any plastic covers that may impede access.

Placing a towel underneath the blender during disassembly may be beneficial in preventing damage to anything on your countertop if something falls or gets knocked loose.

Once everything under the hood has been successfully removed, inspect for any bent or broken parts, such as the pins holding it together or a ridged ring around where the blades fit in place.

If all else fails, search online for directions on how to replace the specific parts for your particular machine.

As shown, common issues that prevent Ninja blender lids from locking can be resolved relatively easily by replacing or repairing the part yourself.

However, if none of these solutions work, it may be necessary to buy a new jar because the problem may be more severe than mere inconvenience.
