How to Fix A Broken Blender

Imagine making tomato puree or your favorite smoothie with your hands! We cannot imagine cooking food without a blender; the kitchen comes to a standstill if the blender is broken.

The following article houses more such fixes for broken blender jars, damaged motors, leaking gaskets, and many more! Along with that, this article will discuss how to repair blenders at home to ensure their smooth functioning.


Instructions on how to fix some common errors when using a blender

Not every problem in the blender requires a technician. Specific common errors can be fixed at home by you! This section will discuss how to resolve common errors to ensure smooth functioning and safe utilization of these magical machines.


1. Blender does not run.

Specific issues and errors cannot be diagnosed without professional help. When utilizing outdated or worn-out blenders, the problem of a blender not starting is a regular complaint. The machine has probably been utilized too much; therefore, it might be time to swap it out for more modern and innovative equipment.

If you face this issue with a new blender, it may be due to the breakage of the cord. The cord needs replacing to prevent the shirt circuit in such a situation. It cannot be done without professional help; hence you may want to call for help unless you are well versed with the machine.

Other reasons the blender may not work are motor heating, faulty buttons, gear damage, etc. The only solution for all the above-mentioned issues is replacing the broken parts.


2.  The blender disconnects itself during operation.


Thermal relays are self-operating devices that are present in electrical equipment to prevent damage due to overheating. Most of the time, the blender disconnects while in operation due to engine overheating.

The engine may become hot if the blender is used for an extended period without giving it a break. In such situations, allowing the engine to cool is best to prevent damage.

If the machine is cool to touch, check if there is a disturbance in the power supply. The blender will stop working if the faulty button or the current is improper.


3. The engine is still running, but the blade is not rotating

Another primary reason why the blender might stop working is the density of the food item. If the item you wish to blend is bulky and not chopped finely, it may hinder the operation of the blender.

If the gear connecting the mixer motor and the blade is not rotating and functioning correctly, even though the motor is on, the blades will not be able to move.


4. There is a burning smell from the blender.

If the blender smells while in operation, turn off the mixing grinder. Since the rotating motor and rotor are connected and synchronized, it may cause friction. It can, in turn, produce a spark and release a burning smell.

The burning odor could result from the rubber component in the blender melting, as the gear connecting the motor and the blades are made of plastic.

In such situations, make sure you dont blend anything for a long time. Make sure the machine gets a break while it is working.


5. Blender Leaking

A leaking blender is always bad news, especially if you have to clean the mess afterward. To fix this issue, try to analyze and understand the origin of the problem.

Most of the time, the leakage is due to a cracked lid or damaged jar. Since these cracks are not visible unless you try to look for them, it may not be easy to spot them. In such a situation, replacing the lid or the jar in question is best.

If the leakage is due to a damaged gasket, try removing the rubber and refrigerating it for 10 hours. Keeping rubber at low temperatures can compress it.

Often, the leakage may be due to overfilling the jar. Hence, make sure you understand your mixer’s size and capacity.


6. Could not adjust the blender switch

Every blender comes with switches to provide multiple settings. If you notice that the buttons are getting stuck and not working efficiently, you can fix it. If the color is faded or oxidized, try to read the actual orientation of the button in the manual.

If gunk accumulated between the buttons hinders its operation, you can use a toothpick and cue tip to remove the assembled dirt. Simply dip either of them in detergent and clean the buttons.


7. The millstone cracked

A crack in the mill can be due to many reasons. If it is not stored correctly, sharp or hot substances are ground in it, and the mill can be affected. If you notice that the mill is tempered or damaged, avoid using the mixer because it can break the jar.

If such a situation arises, it is best not to use the equipment further because it can cause leakages and be dangerous for the user.

Furthermore, if you grind a liquid, leakage can damage the motor. To prevent this, buying a new jar that matches your blending machine model is the best solution.


How to Repair a Blender


Anything can go wrong with a blender, from motor damage to tempered jars. Since these motorized blenders are used daily for cooking meals and making smoothies, it is always a good idea to know a few tricks to help repair the blender.


Servicing the Multispeed Switch

A multispeed switch is the most used switch on the blender. Let’s have a look at specific steps that can be done to service the Multispeed Switch.

Step 1: Turn the machine upside down and remove the base. Since the entire machinery is at the bottom, try to be careful while doing this.

Step 2: You will notice a panel of switches attached with clips. Check if there is any physical damage on the switches.

Step 3: If the switch is loose, you can use a screwdriver and tighten them. If you notice a color change, the wire has burnt for some reason. In such a situation, call for professional help.


Replacing the Fuse


Fuse is present in every electrical device to ensure there is never a current overload. If the current is too much, the fuse melts. It breaks the circuit and hence stops the machine from operating.

Step 1: Open the base from the machine and find the fuse wire.

Step 2: Use a multitester to check the health of the wires. The circuit is open if you notice that the wire is torn or broken.

Step 3: In such a situation, replace the fuse before using the blender to prevent the motor from burning.


Servicing the Motor


A motor is the most rigid part of the mixer. If used properly, the motor will remain intact and serve the user for years. If the motor is burnt or damaged, it is best to invest in a new blender.

An ohmmeter can be used to test the health of the motor.

Step 1: Place a probe on both the cord prong.

Step 2: Select a specific speed and check the readings.

Step 3: Next, tighten the stud clockwise once. If the reading changes, the motor is damaged.


Tightening the Drive Stud

If the stud connecting the motor to the blade is not tight, it can hinder the movement of the blade. Hence from time to time, check the stud to ensure that the blades are spinning at a reasonable speed.

Step 1: Remove the base of the blender. Find the drive stud.

Step 2: Using a towel, hold the shaft with pliers. Attach a wrench to the stud.

Step 3: Holding the shaft steady, start rotating the wrench along with the drive stud in the clockwise direction to tighten it.

Step 4: If you want to replace the stud, rotate the wrench in the anti-clockwise direction to remove it from the assembly.


Service the Blade Assembly

Blade Assembly

The blade assembly is located at the jar’s base. The blades are positioned around an axis to promote the mixer grinder’s centrifugal action. While the equipment is in use, the driving stud ensures the blades are spinning.

Step 1: Detach the blender’s base and locate the drive stud and the knob connecting the blades.

Step 2: Using a wrench, tighten the assembly and the stud.

Step 3: If this does not solve the problem, inspect if there is any physical damage. If you notice any inconsistency in the rubber or plastic gasket, replacing it is advisable.


Which brand is the best blender?

The answer to this may vary depending on your requirements. But if I had to choose just one all-purpose blender, I’d go with the Vitamix Explorian E310.

The blender has 10 distinct speed settings, allowing you to select the rate at which to blend the ingredients precisely. The blades are made up of stainless steel that is sharp and durable.

The pulse feature is also helpful as it can give you a chunky textured final product. This blender’s 2-peak output HP motor is a strong one that can smoothly pulverize even the toughest ingredients.




FAQ 1: Can a blender overheat?

Answer: Any machine, when overworked, can become hot. Likewise, if a blender is overused without giving it a break, the motor can overheat, damaging the blender.


FAQ 2: How long should the blender last?

Answer: Even though blenders can last a decade, it is advisable to replace them every 5 years since new and advanced technologies are gracing the market every day.


FAQ 3: Why are blenders so expensive?

Answer: From mixing ingredients to blending purees, cooking has become more accessible due to blenders. Since these machines are designed to withstand constant use, they are expensive.



Knowing how to fix blenders is crucial since these appliances can reduce the time we spend cooking meals.

Identifying a problem is the first step in solving it. Once the problem is located, you can try to fix it using the methods mentioned above. If the issue is in the gasket or the jar, it is best to replace it. If the issue is overheating, try to use the mixer at intervals. If there is a burning smell, check for leakages and motor-related issues.

If you cannot resolve the issue, you can always get in touch with a professional to fix it.
