It should be noted that it is worth disassembling the airfryer only in extreme cases. Indeed, sometimes it happens that we forget to plug the device into the outlet, but we think that it is broken. The problem doesn't exist though. Therefore, you should first try all possible options before proceeding with the "surgical intervention".
And the device should be disassembled, strictly observing safety precautions.
If it turns out that the fan in the device does not work, you should disassemble the airfryer, get to this element and visually assess whether there is any damage, whether all wires are connected properly. If the wiring breaks, it must be soldered using a soldering iron and solder. Otherwise, the fan may need to be replaced. To do this, you need to purchase one of the same size and characteristics.
The problem is either with the circuit or with the heating element. Everything should be visually assessed after disassembly. If there is an open circuit, it must be reconnected. If the element has carbon deposits, its size has changed, it will have to be replaced. Sometimes it is possible to restore the device, but it is most often within the power of specialists.
How to carry out repairs, everyone decides for himself. After all, for this you must have at least elementary knowledge, experience in handling technology. If there is no such baggage, then you should still contact the workshop. This will be more reliable, and the likelihood of restoring the performance of the airfryer at the same time increases significantly.
I bought an airfryer, but it turned out that the fan did not work, I called the operator and said to bring it, I think that it can be brought back here to the workshop and how much the repair will cost, I live in Novogorsk
An airfryer is considered a hybrid of an iron, a quartz heater, and a wind blower. Working together, they will allow you to get mouth-watering delicacies that would be problematic to prepare using other methods. We believe that the inhabitants of America adopted the technology of smoking bison from the Indians, then the methods of frying were introduced into everyday life. The grill resembles a skewer hanging over a fire. In fairness, let's say infrared radiation makes a small contribution to cooking, the chicken turns out to be browned, tanned. Do-it-yourself airfryer repair is much easier than, say, an iron. The screws are not hidden by elaborate decorative elements, buttons, knobs. A repairable device looks more attractive on the Russian market than a beautiful, but disposable one.
Thanksgiving is celebrated in memory of those who survived the hungry winter of the coast of colonized America. The settlers were helped by the local Indian Tiskvontum, who was subsequently poisoned, according to historians, by his warlike brothers.
The grill of the airfryer plays the role of both an infrared emitter and a heating coil blown by a fan. The device has an infrared (halogen) lamp that acts as the primary heat source. The cover is removable (start with it when you need to repair the airfryer), the ring element is located at the bottom of the perimeter. Separated from the working compartment by a giant glass bowl by a steel grate with free-form holes. If you take the repair of the Hotter airfryer, you will also have to face the mechanism for lifting the lid on the hinges.
They said that the airfryer device resembles an iron for one simple reason. The regulator is made according to the scheme based on a bimetallic plate. Of course, there are many designs, it is powerless to list everything, simple devices are arranged like this:
Self-repair of airfryer requires knowledge of the internal structure. There is a switch at the input of the electrical circuit, pressed down by a handle. The fan motor is powered by a timer. A relay is connected in parallel to the branch (regulated by the corresponding knob), a quartz incandescent lamp. For convenience, a couple of indicators:
Timer operation. The lamp is on while the cocked mechanism ticks.
Quartz work. The lamp lights up synchronously with the heating element.
Newbies are wondering why indicators are needed. They will come in handy when repairing the airfryer with your own hands becomes inevitable!
The quartz indicator is on, there is no heating, cook five hundred replace the spirals.
While the timer indicator is on, the program is running. Even if the spring mechanism stops. In the rest position, on the contrary, neither the indicator should light up, nor the quartz lamp should warm up.
Note the self-cleaning mode on the temperature controller.Today, a popular word, the airfryer could not do without the option, of course.
In fact, nothing complicated. A bucket of detergent (dishwashing) water is poured into the bowl so that the foam does not reach the fan. The timer runs for 40 minutes. After the specified time has elapsed, the quartz lamp grill and fan blades will become much cleaner.
Why the airfryer is designed like this is a big question. Judge for yourself:
There is a quartz lamp inside, separated from the working compartment by a grating. The steel is specially equipped with thick slabs so that half of the radiation is left by the grating. Where does the rest go? Heats the table, floor, cooks, ceiling!
This is not rational. It is known that the efficiency of a halogen lamp is 98%, if the light heats the room, it is not good for cooking. The airfryer bowl is made of glass, stops ultraviolet radiation, not infrared. It is definitely useful for a cook. Infrared radiation is used for treatment, prevention, removal of post-syndromes in diseases of the nasopharynx. Feel the warmth of the airfryer lamp by raising your hand. Not convective heating! When the lamp turns off, the hand stops feeling warm. The only big drawback of the Airfryer.
The appliance does not work in automatic mode when cooking other dishes. Some will argue: the multicooker is not omnipotent. However, the main recipes are automated. You will have to try over the side ones. In an airfryer, we consider the dominant advantage to be the advantage of producing roast without oil. You cannot automatically prepare the main dish. The cook must track the actions of the airfryer, turn the meat on the wire rack at the right time. In the recipe book, the moment is missed, the chicken will not cook on one side. The roast is baked on top, but it receives little heat from the bottom.
From what has been said, it is clear what can break:
The quartz lamp burns out.
The engine fails.
The relay breaks.
The timer refuses.
The main types of malfunctions. The airfryer is cleaned regularly.
VIDEO You should start with a quartz lamp grate. Then the lower blades and the partition are removed. Having removed the upper "squirrel cage", we get access to the wall of the engine compartment. Behind it is the filling of the device. The quartz lamp is attached to the partition with brackets. The cable connectors are removable, it is better to dismantle, do not touch the metal fasteners. Unless, of course, you need to replace the quartz lamp.
The airfryer is not an iron, but the screws can be hidden under the decorative elements. Primarily handles. In many models, screws are hidden under the grill of the quartz lamp. The steel blades are held in place by a central nut. Do not grasp when disassembling. On the back of the blades there is a grip nut, or disassembly is not done on this side. In the course of the master, some of the readers will ignore the words, - in case of a successful experience, write off in the comments.
We hope that now the readers of the VashTechnik portal can repair the Hotter airfryer, repair the Ves airfryer, which are arranged in a similar way. Cook barbecue, chicken. It turns out great, it fits into the mouth even better: om-nom-nom.
The airfryer is intended for cooking food by heat treatment. The products are heated by a stream of hot air. Constructively, the airfryer can be divided into three components: a heater, a fan and a control unit. Do-it-yourself troubleshooting and repair of the airfryer at home can also be divided into several stages according to the number of nodes:
the device does not turn on or the operating modes are incorrectly set;
the air does not heat up or does not heat enough;
there is no airflow, the fan hums strongly.
If the device does not turn on, the indication on the control unit does not light up, then the search for the cause must be started with external inspection of the device ... The problem may be a defective power cord, electrical plug, or damaged case.
If the integrity of the insulation of the cord is broken, it must be replaced. The power cable may not be damaged externally, but it may still be defective. You will need a multimeter to check. The cord is disconnected from the device and checked for contact between the ends of the cable with a multimeter in resistance measurement mode. The serviceability of the fuse is also checked, the blown one changes.
Many models of airfryer are equipped with limit microswitch on the lid, which does not allow the heating to be turned on when the working bowl is not closed. If you press the switch with your finger, you can hear a distinct click. The lack of sound indicates a breakdown of the contacts. The limit switch can only be replaced after disassembling the cover body. The cover is at the same time a body that contains all the working elements.
A lighted indicator indicates that the device is receiving power, and the previous step can be skipped. If the device still does not work, it is most likely out of order. control circuit ... Unfortunately, its repair requires specific knowledge; it is impossible to consult an unprepared person in absentia. However, the problem may lie in the breakage of the connecting wires between the parts of the device. To inspect the wires, you will need to disassemble the case.
You need to start disassembling the unit by unscrewing the screws securing the mesh from the bottom of the case.
Shown are photographs of disassembly using the example of a Hotter brand airfryer.
The heating element and fan blades are visible under the mesh.
The screws and nut highlighted in the photo allow you to disconnect the part of the device on which the heater is fixed. The contacts of the heating element are highlighted below.
Checking the heating element if it doesn't get hot. We disconnect the terminals with wires from the heating element, now it is possible to check its serviceability. The check is carried out with a multimeter in the same way as the cable was checked. A faulty heater will indicate an open circuit, the heating element will have to be replaced. Along the way, with disassembly, they inspect the connecting wires for damage, the cause of the problem may lie in this.
In more expensive models, heating is done with a quartz lamp. Its malfunction can be determined by the glow: there is no radiation or the lamp periodically goes out - the lamp needs to be replaced.
Typical malfunctions of the airfryer blowing system:
there is no airflow;
the fan hums when turned on;
a rumble or grinding noise is heard during operation;
the air flow is too weak.
To check the fan, you need to continue to disassemble the device. We unscrew the screws securing the lower part of the fan and the electric motor.
We inspect the electric motor.
One of the possible reasons why the engine and, accordingly, the fan rotates slowly or does not rotate at all, may be the ingress of fat on its shaft. Once solidified, the fat interferes with the normal operation of the engine. This can be seen in the picture. Therefore, a hum is heard: the engine cannot cope with the load and its winding begins to hum.
The accumulation of fat is removed with a rag, and the residues are washed off with gasoline, alcohol or other liquid that dissolves the oil. It is not enough to simply remove the fat from the shaft. Need to produce shaft lubrication ... This requires Tsiatim-type machine oil.
In the absence of specialized oil, you can use petroleum jelly, but when heated, it becomes liquid, drains from the shaft, and soon the operation will have to be repeated.
Rumbling, grinding, and other unpleasant noises during operation can be caused by bearing failure on the motor shaft. The bearing is located on the back of the motor.
Most often it is also a matter of thickened grease ... By unscrewing the two mounting screws, one gains access to the bearing itself. As before, we put new grease inside it. We return the cover to its place and make several turns of the shaft with our hands to evenly distribute the oil.
All suggested operations make sense when the motor winding is intact. ... Therefore, during disassembly, we carefully examine the connecting wires for integrity. We call the conclusions of the motor winding with a multimeter. A break in the winding is usually not possible to eliminate; replacement of the electric motor will be required.
A limit switch on the cover was previously mentioned. To get to it, you will have to disassemble the entire case. But you can check its serviceability in another way. To do this, you need to determine which wires go to it from the printed circuit board. It is not difficult at all: two conductors go in his direction. We disconnect them from the circuit board and connect a multimeter to them. When you press the limit switch, the resistance on the tester display should change from infinity to zero. Otherwise, the limit switch is defective and needs to be replaced.
Possible malfunctions of a fairly cheap model from Hotter have been discussed above. Similar manipulations can revive similar Airfryer from Supra. Expensive air grills have a more complex device, they are controlled electronic circuits , therefore, it is better to repair them in service centers, although you can try to fix some of the above faults yourself.
VIDEO Behind the external simplicity of the airfryer design, there is a rather complex, multicomponent device with a wide range of functions. Nevertheless, repairing an airfryer with your own hands with replacing the heater is quite affordable even for users with a minimum of technical knowledge. Functionally, this is an improved version of the convection oven, designed for cooking using streams of heated air.
The main structural elements are:
heat and shock resistant glass container;
cover with built-in electric motor, heating element and a pair of fans;
the control unit on the cover bracket.
Despite the overall reliability and durability of the device, its main components are not insured against breakdowns. Their occurrence is often associated with trivial wear and tear during prolonged and intensive use, neglect of instructions, voltage drops and other unfavorable factors.
There may be several such malfunctions, but the failure of the heating element occurs most often and is relatively easy to fix on its own in comparison with other technical problems.
The lack of heating is not always caused by a breakdown of the airfryer itself or a malfunction of the heater. First of all, you need to check the device for inclusion. This is a common problem, the likely reasons for which could be:
lack of voltage in the network;
outlet malfunction;
loose contact of the power cable;
wrong choice of mode;
lid not tightly closed.
VIDEO
If the device turns on, adjusts, but does not reach the operating temperature, the most likely cause is a malfunction of the heating element. Depending on the design features, it can be made in the form of a halogen lamp or various versions of the heating element. Placement is the bottom surface of the cover. The lamp or heating element is fixed on special holders and connected with contacts to the control board. Externally, the element is covered with a protective grill.
The repair will have to start with disassembling the structure. The process is straightforward and intuitive. You will need a Phillips screwdriver to complete it. After unscrewing the mounting screws, you need to:
remove the protective grill;
remove the retaining brackets;
dismantle the heating element;
release contacts.

If a gologenka is initially installed in the airfryer, you can try to replace it with a heating element with a spiral. Its advantage is its greater working life. The lamp is designed for a couple of years of trouble-free operation under standard conditions. The service life of a high-quality heating element without replacement is five times longer. Another advantage of this option is maintainability.
If the problem is related to the breakage of the spiral, it can be restored.But this is acceptable in cases where there is no workable analogue. A reconditioned coil will not last long, plus its repair will take a long time.
Therefore, in both cases, it is recommended to immediately replace the defective part and check the repaired airfryer for heating.
In addition to the heating element, the inoperability of the airfryer may be associated with other breakdowns. Not all of them can be fixed on your own, but it will be useful to know about them. Frequently cited fan failures and control box failures.
This is the most important element of the device, which ensures uniform baking, frying the product by blowing with a directed hot stream. It turns on when the heating element reaches the specified temperature regime. In the event of a failure, the cooking quality is reduced. The problem may be associated with a break in the soldering, which can be easily restored on its own, without leaving home without visiting a service center. If the node is completely inoperative, it must be changed to a working one:
for this purpose, it will be necessary to completely disassemble the cover;
conduct a visual inspection of contacts;
if they are in order, replace the node with a workable one with an exact match of those. parameters.
VIDEO The most difficult malfunction for self-elimination, requires skills in working with electronics. The control module ensures the functioning of:
Externally, the control panel can be made in a push-button or a more modern touch-sensitive version, which is more prone to failure. With such a breakdown, the device does not turn on or refuses to accept the settings for the desired operating mode.
Self-repair in this case is hardly possible, the most that can be done is to make sure that the element is faulty, that is, check the condition of the contacts and the presence of voltage with a multimeter.
The board is located in the device case, fixed above the cover; to access it, you will have to completely dismantle the structure. After making sure of its malfunction, it is best to return everything to its place and contact the service center.
The best way to avoid malfunctions and prolong the life of your airfryer is to follow the manufacturer's instructions exactly. If, nevertheless, a breakdown has occurred, you should not rush and puzzle over the question of how to repair the airfryer with your own hands. First of all, you should correctly assess the complexity of the problem and possibly refer your device to a specialist. It will be more expensive, but will avoid wasted time and loss of the device associated with self-repair errors.
If your household appliances are out of order, then you shouldn't say goodbye to them. You don't even need to take it to a service center. Instead, check out the instructions and tips to help you do your DIY Airfryer repair.. Common malfunctions have long been described, and the design is clear and not particularly complex, so you can get down to business.
Convection oven is a kind of air-draft oven, a mixture of a heater and a fan. A special grill serves as a heating element, which in turn is blown by air currents. The primary heat source is an infrared lamp. All of these critical parts are separated from the glass bowl where the food is placed.
The design usually consists of several elements:
sealed glass bowl;
quartz lamp, covered with a grate and slightly lowered into the bowl;
a fan, consisting of lower and upper blades (the lower ones work to blow food, and the upper ones cool the motor);
partitions between the blades with openings for air outlet;
bimetallic plate for temperature control;
control unit and display system.
The lid is usually equipped with a functional handle that completely disconnects the power when opened. Cooking starts only when the appliance is sealed.Problems can be associated with the listed elements, therefore, do-it-yourself airfryer repair often begins with diagnostics.
Any repair of a do-it-yourself electric grill or a similar device requires familiarity with the internal structure. The wiring diagram consists of a switch on the cover and a handle. From it, the signal goes through a timer to the motor that starts the fan. Relays and quartz lamps are connected in parallel.
Often you have to deal with the following malfunctions:
the device does not turn on and does not respond to control;
the device heats up weakly;
the fan of the airfryer does not spin;
the main control unit has broken.
VIDEO Typically, a chicken weighing about 1.5 kg is cooked for about 1 hour. The degree of readiness can be observed through the transparent walls. If the terms noticeably increase, then this indicates possible malfunctions. There are other problems - the airfryer simply does not respond to button presses or other malfunctions occur. But your device can still be repaired.
The design of this device has already been considered above. It is not difficult, which allows you to quickly repair the airfryer with your own hands. Usually one of three main components breaks:
thermal fuse;
a heating element;
Control block.
The third option is the most serious problem, because in this case it is quite difficult and expensive to repair the device. In addition, only specialists should be involved in restoration, but even they cannot guarantee a 100% result.
Breakdowns of the thermal fuse and heating element can be easily eliminated, and you can do everything yourself with minimal knowledge and tools. For this, a multimeter is suitable, with which all the elements are called.
If the heating element is out of order, then you can simply buy a new heating element. An ordinary steel model is inexpensive and can last for ten years. However, the disadvantages include slow heating, high energy costs. You can spend a little more, but buy more efficient carbon or halogen heaters.
If the problem lies in the thermal fuse, then usually the airfryer does not turn on at all. A short-term power surge often leads to this problem. Before taking any serious action, though, it's best to check the outlet and wiring as well.
Do-it-yourself disassembly of the airfryer is performed in several stages:
the quartz lamp grate is unscrewed;
the lower fan blades are dismantled;
the partition between the blades is removed;
the upper "cage" is removed (the motor of the device opens behind it);
the quartz lamp is removed, which is fastened with brackets to the partition;
if you need to replace the quartz lamp, you need to dismantle the cable connectors.
Before starting work, you should carefully inspect the airfryer body and find all the screws that are hidden in deep grooves or behind decorative plugs.
The steel blades should be removed from the rear, where the grip nut is usually located. It will be much more convenient and safe this way.
Do not forget that before you start repairing your Airfryer, carry out a full diagnosis. There are several reasons that can be misleading:
the outlet is out of order;
the device is incorrectly configured or the wrong mode is selected;
the cover is not fully closed.
Sometimes it is cheaper to replace one or another part than to buy a new airfryer. You can repair it with your own hands quickly and efficiently.
The first malfunction that is most often encountered is that the airfryer does not turn on. You should not panic, because sometimes the following commonplace situations can be the cause of a breakdown:
The plug is not plugged into the outlet, or the contact is poor. No matter how strange it may seem, but still the lack of power is very often the so-called reason for the breakdown of the airfryer.Pay attention not only to the contact with the outlet, but also to the connection of the cord to the equipment itself (at the back, as shown in the photo). Very often it is the last connection point that causes problems. In addition, check the integrity of the cord that you may have interrupted. If necessary, replace or repair the damaged area yourself. We talked about how to replace the plug in the corresponding article!
The socket is out of order. Check the connection point itself for voltage. The airfryer may not turn on because the socket is not working. All you need for repair is to check the voltage in the socket with an indicator screwdriver as shown in the photo.
The correct mode is not set. If the display is on, but nothing happens when you press the "Start" button, most likely you have set the operating mode incorrectly. This will be evidenced by a timer on which the numbers 00:00 will be displayed.
The handle is not pushed all the way down. In many models, a button is installed under the handle that protects the equipment from accidental activation. If the handle is loose, you will not be able to start cooking.
If all of the above points do not fit your case, you will have to make a more complex repair of the airfryer on your own - disassemble the case and check each element of the chain in turn.
For "continuity" of parts, you need to use a special tester - a multimeter. Use this instrument to check the resistance of the fuse that blows during power surges. If the airfryer really does not work due to the failure of the thermal fuse, replace it with a new one with the same parameters (it costs a penny). Replacement instructions are provided in the video tutorial:
VIDEO To prevent this malfunction from bothering you anymore, we recommend installing a network surge protection device!
If the fuse is normal, ring all the other elements of the circuit - heating element, control unit, and also visually inspect all wire connections. Perhaps, somewhere there was a break in the contact, which will need to be soldered. You can see how this technique works in this video:
VIDEO In the event that the airfryer does not heat up or heats up weakly from below, we can say with confidence that the heating element does not work. The cause of the malfunction may be wear of the heating element at the end of its service life or an open circuit. In the latter case, you can try to repair the damaged area, but according to many reviews on the Internet, it is easier to buy a new part than to spend more than one hour on repairs.
By the way, it should be noted right away that a heating element in the form of a halogen lamp fails more often, the service life of which is already 2 years compared to 10 years of a metal heating element. If the lamp under the cover does not heat up, you should not replace it with the same one. It would be much more correct to replace the heating element yourself with a metal one. In this case, you will need to dismantle the protective grille, remove the brackets, unscrew the heater and disconnect the wires. After replacement, parts are assembled in the reverse order. As you can see, repairing the airfryer with your own hands, which does not pick up the temperature, can be done by yourself without certain knowledge of electrical engineering!
Also, you may encounter such a situation when the airfryer does not fry the bottom of the dish or does not heat up at all due to the fact that the fan is not spinning. In this case, the repair of equipment comes down to the fact that it is necessary to disassemble the case and visually view the contacts connected to the fan. If there is a wire break somewhere, solder it. In the event that the fan does not work completely, it is better to replace it with a new one with the same parameters and dimensions.
To help you understand the importance of good fan performance, we will now briefly describe its operating principle. When the heating element heats up to a certain temperature, the fan starts spinning and blows hot air towards the food.If the fan does not work properly, a situation may arise when the airfryer does not bake well or does not fully cook food from below.
Well, the last, most difficult malfunction is when the control unit does not work - a timer, a thermostat, a button for switching on or switching modes. In this case, a reverse moment may even occur when the airfryer does not turn off. Most often, this situation occurs with touch screens, although they are comfortable, they are more prone to breakdowns and expensive repairs.
The only thing you can do is check the integrity of the contacts and ring the touch panel with a tester. If it really does not work, repairs will not be within the power of a novice electrician, so you will have to take the equipment to a service center. Do not be alarmed, because the situation when the airfryer does not work due to a malfunction of the control unit is very rare and occurs only if you bought a cheap Chinese model of the device.
So we have listed all the most popular malfunctions of this type of household appliances. As you can see, it is quite possible to repair the airfryer with your own hands, so if the device does not work, now you know what to do to repair it yourself!

VIDEO The airfryer is a convenient multifunctional device that allows you to cook delicious meals by thermal processing of food. If this device stops working when it is still new and is under warranty, then it is recommended to take it to a specialized center. There professionals will be engaged in the repair of the airfryer. If the equipment has already served, and the warranty period has expired, then you can try to fix it yourself.
Convection oven is a device that main nodes which are:
a heating element;
fan;
Control block.
A more detailed structure of the device is shown in the following photo.
The numbers in the photo correspond to the following structural elements:
cover with fan and electric heater;
control Panel;
cover bracket;
cover lifting mechanism;
plastic case;
flask;
network socket;
electrical cord.
As a rule, on the cover of the device there are power on / off button ... When you open the lid, cooking stops automatically. If the device is not closed tightly, it will not start working.
Repair of the device at home you need to start with diagnostics , that is, with the search for problems. Common faults include the following:
the device does not turn on at all or it suddenly turns off itself;
operating modes are not set at all or are incorrectly set;
the light panel goes out periodically;
air heating is weak or absent at all;
the fan does not work (no blowing).
If the airfryer does not turn on, and, in addition, there is no light indication on the light panel, then the first thing to do is to inspect the device for external breakdowns. It is possible that the cause of the malfunction is damage to the case, power cable or plug.
In the event that the cable is damaged, it is enough just to change it with a new one or reconnect the wiring at the break and insulate it. The cord may appear intact on the outside, but it may not work. To determine the integrity of the cable cores, you will need a multimeter (pictured below).
Important! For diagnostics, you need to disconnect the power cord from the airfryer and in the resistance measurement mode set on the multimeter, check the integrity of the cores: touch the probes to the opposite ends of each of them. If the wires in the cable are intact, then the device will show that their resistance is practically zero. When there is a break in the core, the multimeter will give infinity.
Further, with a multimeter, in the same way, you must check fuse ... If it does not work, then it should be replaced.
Conveys on the lid contain limit micro switch ... It blocks the operation of the device if the lid is not closed hermetically. When you press the switch, a characteristic click should be heard, which indicates its good condition. If there is no sound, then this may indicate bad contacts or their breakage. The end switch is replaced by disassembling the cover shell.
To check the limit switch and not disassemble the entire cover, you need to determine which wires fit to it from the control board: as a rule, only two wires are connected ... Next, you need to detach them from the electrical circuit and connect to a multimeter. When you press the microswitch, the resistance value on the device should change from infinity to 0. If there are no changes on the multimeter, then the limit switch does not work and needs to be replaced.
If all the lights on the device are on, then this indicates a good power supply. But in the case when there is no heating or blowing of the prepared products, it is recommended to contact a specialized center. With such a malfunction, most likely there was a wire break connecting the parts of the device.
Lack of heating or blowing can also be due to failure of the control unit. In this case, the following elements do not work:
timer;
thermostat;
mode switch button.
The problem with the control unit most often arises with cheap, non-original, devices without certificates with touch displays. The problem is considered one of the most difficult breakdowns requiring special knowledge in the field of electrical engineering to eliminate. In case of malfunctions of this kind, it is better to immediately disconnect the device from the mains by removing the plug from the socket.
For self-repair, you need to check the integrity of the contacts and ring the board using a tester (multimeter). In the event that there are no signals, then home repairs will be very difficult for non-professionals. It is better take it to the repair shop unit.
If the control unit functions normally and the entire internal wiring is intact, and the device heats up very little or does not heat up at all, then the heating element does not work. In the airfryer, heating can be carried out by Heating element or halogen lamp (or its carbon equivalent). The latter fails more often, since it has a shorter service life (about 24 months) compared to the heating element (about 10 years).
Halogen lamp or heating element can be replaced by yourself for parts of the same power. To do this, you will need to disassemble the entire device. In this case, the first thing that needs to be done to replace the heating element is to unscrew the bolts that hold the mesh from the bottom of the device case (as an example, a model from the Hotter brand is taken).
Under the net there are heating elements and fan (in the photo below you can see its blades).
The next photo shows the contacts of the heating element.
Important! To check the health of the heating elements, it is necessary to disconnect all contacts. The operability is checked using a multimeter, just like the power cable: in case of a breakdown, the tester will show an open circuit. Then the heater needs to be replaced.
Definitely recommended view all wires for breakage or poor contacts at their connections. This is due to the fact that the reason may be precisely in them.
There are several signs by which you can determine that defective fan :
no airflow or very little airflow movement;
the airfryer hums when turned on;
during operation, an uncharacteristic rumble or grinding noise is emitted from the device.
To identify the reasons, it is necessary disassemble the device further ... It is necessary to separate the lower part of the fan and the electric motor (they are fastened with screws).
Next, you should carefully inspect the engine : you need to inspect the winding and all connecting wires for the presence of burnt areas and for their external integrity.
If fat gets on the shaft and solidifies, then it can cause malfunctions of both the electric motor and, accordingly, the fan. In this case, the fan blades will spin very slowly or will not budge at all. Recommended clean the shaft engine from contamination. Then it should be lubricated with a special machine or gun oil.
If the motor winding is outwardly intact, then you will need to use a multimeter to determine the presence of internal breaks in it. For this, the device must ring the winding pin ... In the event of an open circuit, you will need to buy a new electric motor.
