A meat grinder is simply an indispensable device for grinding various types of meat. Previously, most housewives used hand-held machines, but now more and more users prefer electric devices. This is not surprising, because an electric meat grinder grinds meat of any quality in a matter of minutes, saving time and effort of the hostess.
Unfortunately, all electrical appliances tend to break, and repairing them is somewhat more difficult than manual ones. How to repair a meat grinder at home, and what you can do with your own hands will tell this article.
An electric meat grinder has broken - what to do: do-it-yourself electric meat grinder repair
Repair of manual meat grinders
Manual meat grinders are completely composed of mechanical parts. When parsing, it is always easy to see the breakdown and replace the damaged part with a new one. Moreover, all components are easy to find on sale.
There is nothing special to break in a manual meat grinder. Most often they have blunt knives that are easy to sharpen with a small grinding wheel. Such a circle is put on the axis of the meat grinder instead of the net for the output of products and perform rotational actions with the handle, as when grinding meat.

Sometimes a strong creak is possible during the operation of the device. Then you should disassemble the mechanism, lubricate the place of rotation of the handle so that the grease does not get into the meat container.
All parts of hand-held devices are made of metal and cannot break when hit by sinewy pieces or small bones, since a person will definitely feel the stress at hand, and will clean the mechanism. An exception is modern manual meat grinders made of fragile metal.
Electric meat grinders
Electric meat grinder
All electrical meat grinders, regardless of manufacturer, consist of:
- engine;
- gearbox - consists of several bearings and gears for transmitting motor power to the rotational movements of the cutting mechanisms;
- knife systems (auger);
- control unit;
- power cord.
Causes of breakdowns
The main reasons for the failure of electric meat grinders of all brands is their improper use. Only a small percentage depends on poor build. The quality of the parts themselves depends on the reliability of the manufacturer. You should not save on it, since repairs can be much more expensive, and it’s not so easy to find parts for sale.

The most common malfunction of a meat grinder:
- the device does not turn on at all;
- the meat grinder turns on, but the disk does not grind the products;
- the drive works, but does not gain the required number of revolutions;
- a burning or smoke is heard during operation;
- amplification of extraneous noise or knocking, which was not previously noticed.
Instructions for parsing and troubleshooting at home
Not always at the slightest breakdown you should bring the device to a service center, where it can successfully lie for many weeks, and even have to pay a decent price for repairs.
If the meat grinder does not turn on at all, there may be a cause of failure in the absence of contact or a malfunction of the control panel.
Disassemble the device by unscrewing all the necessary screws. Sometimes the plastic parts of the case snap together, then you should find all the grooves and VERY CAREFULLY snap them off.Otherwise, the case may be damaged, then it will not be possible to fold it back. An example of a case analysis can be seen in the drawings of the SCARLETT model analysis.

Check all the contacts, the connection of the power cord to the device, maybe something should be tightened or soldered.
If the meat grinder is turned on, but the auger does not grind the products, the cause may be a defective gearbox. Bearings could crumble or gears could wear out due to heavy load or ingress of bones.
In this case, disassemble the relay, check all parts for defects. Are gears easily scrolled, are all teeth present, is there any excess play when moving. Turn on the device in disassembled form without loading the auger.
Mincer Relays Gears
Do this carefully so that all parts do not scatter to the sides and something does not interfere with the engine!
Do not forget to take pictures or remember the location of the parts, so that you don’t have to puzzle over what to put.
Relay failure is the most common cause of failure. meat grinder works.
If the cause was a defect in the gears (which is very likely, since they are made of plastic), replace the damaged parts with new ones. It’s not so easy to find new gears on sale; for most models they are not sold separately. You may have to contact local services to buy the necessary used part from another device or try parts from other models.
In some rare cases, the cause of interruptions in the rotation of the auger may be wear on the socket for its attachment or skew of the shaft. This can occur from a constant increased load on the device or improper manufacture of the socket from too soft metal. Loosening the screw and licking the rotary mechanisms is a very big problem. To eliminate it will require the help of specialists.

If the meat grinder works, but does not gain the required speed, an overload has most likely occurred. This problem is most often found in Kenwood mg devices.
The device should be disconnected from the power supply, disassembled, cleaned and chopped meat before serving in a meat grinder in smaller portions.
The main reason for extraneous noise, knocking in the operation of the devices is getting inside excess objects: small bones or veins. They can get stuck and clog the junction of different parts of the device. Also, on insufficiently washed parts after the previous use, food particles may dry out and cause blockages.
In such cases, the device should be disassembled, cleaned, and all foreign objects removed.
Sometimes the cause of extraneous noise and sharp sounds in the operation of the meat grinder can be crumbling bearings. They are easy to find on sale and replace.
If you hear fumes or smoke from a working meat grinder, most likely the cause is a motor breakdown.
Self-repair of the motor will require some knowledge of electrical engineering, directions of alternating current, adjustment of the synchronous and asynchronous motors. If there is no such knowledge, it is better to immediately contact a service center. But, at the same time, the importance of repair should be assessed.
The price for repairing a motor is usually very high, so it’s sometimes easier to buy a new device under warranty than to repair an old one.
If certain knowledge is available, it should be borne in mind that both spirals of the motor winding are offset 90 degrees from one another. In the second winding, the currents vary in phase. As a result of this difference, the rotor starts. The current difference is created by the capacitor. It is used to provide initial acceleration of the rotor.
Electric meat grinder motor and rotor
Electric meat grinder motors for home use are asynchronous. In them, the rotor speed lags behind the magnetic field of the stator.A spoiled capacitor can be the main cause of a meat grinder breakdown.
If the capacitor fails, it should be replaced with a new one.
When buying, pay attention to the capacitance and voltage rating.
If one of the windings burns out, the motor must be rewound.
In any case, before repairing the meat grinder at home, you should evaluate your strengths and knowledge so as not to aggravate the breakdown.
