Why is My Blender Not Blending? 8 Common Reasons

Suppose you take out your blender, put it on your kitchen shelf, and run it to try some new delicious recipes. But the result does not have the shake you wanted to drink. Do you think I am talking about the taste of your new dish? Of course not! I am talking about the blending problem of your blender.

So, why is my blender not blending? Sometimes a blender stops working correctly due to motor malfunctioning, frozen food texture, blade sharpness, and speed issues.

This article will discuss the most common reasons and some simple ways to overcome this problem.

How Does a Blender Work?

The most important thing to know is the working of a blender. To fix any machine, we need to know the basic working. But before doing anything at all by yourself, check if you still have the warranty card of your blender so you can avail yourself of the chance to replace or repair it. Most of the blenders come with 1 to 5 years of warranty.

Learning the working of a blender can be very helpful because any part of the blender can be working improperly. A blender is a motorized gadget with an electrical cord and speed-fixing buttons, so there can be chances of malfunctioning. It would be best if you are sure about the proper fixing of your jar or cup to the base of your blender. Not just the fixing at the base motor but also the fixing of the lid of your jar.

Why is My Blender Not Blending?

Now let’s see some of the leading causes of when your blender stops blending, or you may experience that the blender is spinning but not blending.

Check Food Product and Jar Adjustment

Sometimes the food items you are using to blend are not just up for it. It can be frozen, too thick, or chunky for the blades to move. If it is frozen, you can wait for a while for it to melt. If the food product is complex, you can chop it into small pieces. If it is still not blending, check if the jar or cup is appropriately fixed to its base or not.

Tip: Sometimes, your jar is not fixed in a proper balance, or it can be fixed in the wrong spot. Readjusting might help to overcome your issue.

Check Food Product and Jar Adjustment

Check the Blades Attachment

This is the most common problem but often ignored one. We start to apply pressure on the blender to fix it, but that’s not how it will work. You need to remove your food item and fix the blades again. Ensure that your blades go down, and there should be no gap between your blades and your jug.

Check the Blades Attachment

Check for Damaged Parts

It is not a surprise if any of your blender’s part is damaged or broken. Usually, any button can break, or maybe a part of your blender’s base is damaged. You can repair or change that part, and you are ready to go.

Check the Motor

At times, continuous usage of the blender without taking a break can cause the burning of your blender’s motor. The indication is just the burning smell coming out of the motor. Taking small pauses while using the blender can also increase the shelf life of your blender. But if your motor is already not working correctly, you have the option to repair or change it.

Check the Leakage in the Jar

Again, it is a prevalent cause, but we ignore it mostly. But the leakage in your jug can be hazardous, especially when it is leaking at the base. The leakage can quickly go down from the base into the base and cause your motor to short circuit. This leakage needs to be dealt with immediately.

You can also buy a separate or a spare jar to overcome this problem. Or you can quickly get it fixed.

Check the Leakage in the Jar

Check the Speed

When we are trying out a new recipe, we often start to pile the food product up to the top of the jar. This can only cause damage, and your product will spill out. The spilling can also be caused by turning the speed of your blender to the highest just after starting it.

It would be best if you increased the speed with little pauses. Turning to the highest speed, in the beginning, can also cause the motor unit to short out without any signal. Your blender will immediately stop working. You can also blend your ingredients separately at low or medium speed to avoid over-speed.

Check the Speed

Check for Blades Sharpness

Sometimes the excessive use of blenders can cause their blades to be dull. The blades can also lose their sharpness, and you will not be able to get the desired result of your food product. You can change the blades easily, but try not to blend ice cubes or frozen food products in your blender to avoid this problem.

Blending frozen food products can also damage your blades, and they will stop working smoothly. In this case, your blender will spin, and it will stop blending the food items.

Multispeed Switch

A multispeed switch is one of the essential parts of a blender. This part can easily be damaged if someone applies pressure on the buttons. You can access the multispeed switch by removing the base of the blender.

Before touching the switch, examine it properly. Most of the time, it is just because of a loosened terminal. You can quickly tighten it back. Also, check the color of the terminals and wires. If the color is black, it is likely to short out, and you can only repair it.

Tip: Always clean your blender after using it. Sometimes food particles are stuck in any part, which causes damage, and when you use it next time, it does not work correctly.

 Read the Manual
