The blender has a fairly simple device. The device consists of a nozzle and an engine. Stationary models are also equipped with a bowl with knives. There is also a cord with a plug for connecting to the network, speed controller, protection against overheating.
To know how to fix a blender, you need to know about the most common malfunctions. The most typical failures are:
- No nozzle rotation. The problem is the speed switch malfunction.
- The device does not work as powerful as before, grinding and mixing of products does not occur. Sometimes the fault is all about engine wear, which is inevitable when the device is used. If the device is running on battery power, it may not function intensively due to a malfunction or insufficient charge.
Important! Sometimes the reason may be the wrong choice of products. It happens that the device’s power is simply not enough for one purpose or another.
- The blender is “silent” when turned on. Most often, the faulty engine or battery is “to blame” for this. Sometimes the device may not turn on due to a decrease in voltage. It is simply not enough for the normal operation of the device. If there are switching sounds, but the device does not work, then most likely something has got into the chopper.
- No switching speed modes. As a rule, the control system or device wiring is faulty.
- Knife breakage. This malfunction is one of the most common, and it arises from the prolonged and intensive operation of equipment. In this case, grinders cannot be repaired; they only need to be replaced.

Fix a blender at home
We will consider all the breakdowns in more detail so that you can understand what you will definitely manage with and what kind of work is better not to start.
How to repair a blender with your own hands if the speed controller is faulty?
This breakdown happens often, but not everyone can fix it. We need at least basic knowledge in the field of radio engineering. If you want to repair the device with your own hands, proceed in this order:
- Disassemble the blender. You will find a step-by-step algorithm on our website in the article "How to make out a blender?"
- Identify the speed controller and unsolder it.
- Using a universal tester, ring all possible options for the positions of the regulator.
Important! Sometimes the operation of the stationary blender is blocked due to the fact that the bowl is not installed or incorrectly installed. For this reason, if the equipment does not turn on or does not work correctly, check that the bowl is installed correctly.
DIY blender nozzle repair if knives are defective
A sign that the knives are dull is the lack of chopping or uneven chopping. Do not try to sharpen knives at home - this can only be done in a specialized center. If the knives are broken, they cannot be repaired, you can only replace them.
Three scenarios of further events are possible:
- Knives are parts attached to a container of a stationary structure by means of threads or nuts. If the knives are fixed on the thread, they must be unscrewed, being careful (it is advisable to wrap the cutting part with a cloth. For knives mounted on nuts, unscrew the latter. After that, the knives can be removed without difficulty.
Important! If the gland is adjacent to the knife, it is advisable to replace it.
- Knives are inside the bowl. Such models come across infrequently, but separate stationary blenders are designed that way. To replace the knives, it is necessary to completely dismantle the bowl, disconnect the cutting part and replace it with a new one.
Important! So that during assembly there are no difficulties, you need to photograph or record the whole process.
- There is no way to separate knives and cups. In this case, there is nothing left but to replace the bowl with a new one.
Important! Disassemble the bowl and remove the knives only when the power to the device is turned off. To avoid an accident, you need to check everything several times. If the blender is powered by a battery, it must be removed for the duration of the repair.
Blender is silent
A very unpleasant situation if the device does not turn on or stops suddenly. This happens if it has been used for a long time, or if the model is not high enough.
Important! To avoid unnecessary problems, you need to purchase household appliances only in a specialized store.
To test the device, do the following:
- Remove the nozzle or remove the bowl.
- Press the button that locks the knives.
As the instrument wears, it sometimes presses and the device locks. After pressing the button, the blender starts working again. If the manipulation did not bring any effect, then the motor is faulty.
Important! Burned out blender - can it be repaired? It is worth doing this - decide for yourself, since in most cases the cost of the engine is commensurate with the price of the entire device. Sometimes it’s easier to get new equipment. In a separate post, we collected all the information about which blender is better to choose.
Sometimes repairing a Polaris blender or another brand with your own hands is not particularly difficult. If the blender does not turn on, check the following points as well:
- Electricity grid. Sometimes the device does not work due to the fact that the outlet into which it is connected is faulty. No special device for testing the outlet is needed. Try to include in it any serviceable electrical appliance: a razor, hairdryer or desk lamp.
- Power wire. In order to test the cord, disconnect the device from the power supply and disassemble the case. Measure the voltage on the cord, and then compare with what is obtained when measuring in the outlet.
- Fuse. If it burns out, the device will not turn on. Remove the fuse and replace it with a new one.
Important! All specifications for the purchase of a new device are indicated on the old fuse.
- Instrument Board Take a close look at resistors and capacitors. Tracks must be undisturbed. There should be no blistering on the capacitors, and resistors should not have burn marks.
