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.
Convection ovens on the lid contain limit micro switch ... It blocks the operation of the device if the lid is not closed tightly. 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 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, it is most likely that 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 an 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, all contacts must be disconnected. 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 to determine the presence of internal breaks in it, you will need to use a multimeter. 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. In this case, the necessary spare parts for repairs can be purchased on the official websites of the manufacturer or in stores that sell household appliances.
Loud sounds during operation of the appliance may be caused by bearing failure on the motor shaft. It is located on the back side.
Very often the problem consists in a thickened grease ... At the same time, by unscrewing 2 screws, you can gain access to the bearing and remove the old lubricant. After that, you need to check the integrity of the bearing. If it is in order, then it must be lubricated with oil.
Important! When the bearing is crumbled, badly worn out, or there is a crack in the cage, then it needs to be replaced.
Next, you need to assemble the airfryer in the reverse order, returning the lid to its place. To distribute the oil inside the bearing and check that the fan rotates easily, it is recommended turn the blades by hand .
An inexpensive model of an airfryer from Hotter was considered as an example for troubleshooting. All the above steps will help you fix similar devices at about the same price, for example, from the Supra company. More expensive devices are made differently. As a rule, inside such airfryer more complex electronic circuits are contained and in case of problems, it is recommended to immediately contact specialized service centers.

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 resting 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.

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.
