Why is blender lagging?

In this brief guide, we will answer the question, “why is blender lagging,” and discuss other questions related to the subject, such as how to know that my kitchen blender is defective, and how to check a lagging blender.

Why is blender lagging?

There are a few common causes for your blender’s lagging:

  1. A slow motor
  1. Too much food and not enough liquid
  1. A burning smell

Blender lag is a technical term for when your blender’s motor is running slower than usual. This can happen either because you have an older blender, or because your blender is defective.

If you have a newer, high-quality blender and it starts lagging, it’s probably because the blades are getting stuck: too much food and not enough liquid will cause this to happen. In that case, just add more water and turn the blender back on.

If your blender is older or defective and you smell burning rubber when it’s on, it’s probably time to invest in a new one.

If you’re experiencing a slow motor, you should check if your blender is an older model or if it’s defective. If so, consider replacing it with a newer model.

You can also see if the blades are getting stuck in the food or liquid you’re blending, which can cause the motor to lag. If that’s the case, add more liquid and blend again. If you smell burning rubber, replace your blender’s motor immediately.

How to replace the lagging blender’s motor?

Here are the steps to replace your motor:

  • Remove the pitcher from the blender base and set it aside.
  • Turn the base over so that it’s upside down on a flat surface. You will see three screws securing the metal plate to the bottom of the blender base.
  • Remove these screws using a small screwdriver. Set them in a safe place where they will not roll away or get lost.
  • Lift up on the metal plate, which is hinged at one end, to access the inside of the blender base where the motor housing is located.
  • You should see two black wires attached to a plug near one side of the motor housing; unplug these by grasping them and pulling them straight out, then set them aside. This will free up the motor so that you can remove it from its housing.
  • Grasp each side of the motor housing and pull straight up to remove it from its mounting bracket. Then remove the entire motor assembly from the inside of the blender base.

How to know that my kitchen blender is defective?

If your kitchen blender is defective, you will notice that it does not blend ingredients at the same speed it once did. It may also be making a loud noise while in use. If either of these is true, you should contact the manufacturer to see what they recommend. You may be able to get a replacement blade or a new blender.

If your blender appears to be defective, you may be wondering how to tell if it is. Here are a few common ways to identify a defective kitchen blender:

  1. Don’t blend your food, leaving you with clumps of ingredients that are not fully mixed;
  1. Makes a loud noise, indicating the motor is malfunctioning;
  1. Does not turn on at all;
  1. Produces sparks when you turn it on;
  1. Shakes violently while running, causing the contents to spill out of the blender jar or onto the countertop;
  1. Do not shut off when you press the power button, indicating a faulty switch or electrical problem.

How to check a lagging blender?

Your blender lagging might be caused by a number of different things. 

First, check to make sure that the power cord is securely connected to the wall outlet and that the cord is in good condition. If you have a removable power cord, unplug it and plug it back in again.

Next, check the outlet to make sure it’s working by plugging your blender into another outlet or plugging another device into the same outlet. If it still isn’t working, try using a surge protector instead of plugging directly into the wall.

If you’re still having trouble, check the blades for any debris like pieces of food or plastic. Check for any cracks or dents on the blade assembly and replace them if necessary.

How do I fix blender lagging?

  • Reset the motor
  • Turn off the blender and unplug it, then plug it back in after a few seconds and try to blend again
  • Check the power cord
  • Make sure the cord attached to your blender is not frayed, bent, or otherwise damaged
