Ordinary toaster, which does not have additional functions, can be attributed to the category of household appliances that do not bring much trouble in the kitchen space. It's simple: the roasting program can be set with a timer, and the operation of the device will begin from the moment the pieces of bread are lowered into it.
Classic Toaster
Baking slices of bread occurs under the influence of infrared radiation until the timer is turned off. However, the elementary principle of operation does not mean that the toaster will work for many years without breakdowns. Nevertheless, many faults can be fixed independently. The material will consider options for eliminating simple house breakdowns, without resorting to specialists. By following the paragraphs describing the disassembly of the device, the repair of the toaster can be done with your own hands.
Frequent breakdowns when using the toaster
It will be useful to know that in addition to the timer and the starting lever in the structure of the toaster there are two compartments for bread, and inside it there are heating elements on both sides - nichrome spirals.
The frying stop button can be considered a circuit breaker - you can stop cooking even before the timer goes off. Some toasters have a temperature sensor, without it, repair will be easier. In total, the toaster has 3 heaters: central two-sided, right and left unilateral.
Simple breakdowns:
- Right under the holes there is a tray for crumble crumbs, but it also happens that they get to where the electronic components are located. If a breakdown has occurred due to this, just disassemble the toaster and clean it well. The screws are usually located under the rubber-coated feet, which can simply be loosened. At this stage, the user will see the bottom contacts. In general, one should always be careful with such a problem - too many small crumbs can cause a fire. A soft brush or rag is usually used for cleaning.
- If paper gets on the spirals of the heating elements, the heater wires may burn out. In this case, do not repair the device yourself. In most cases, toasters break due to magnets. Here it will be necessary to look for a malfunction on the surface of the printed circuit board and, accordingly, eliminate it. To be more precise, there is a microcircuit and resistors in the inside of the appliance, and the absence of capacitors will just allow anyone with knowledge of the basics of electronics to cope with the problem.
- Insufficient power supply by the electromagnet's electricity, which is why the basket may not be fully pressed and it is required to set the regulator to the middle position. The difficulty will not disappear, but toasting this time will be possible.
Failure to lock the toaster lever that does not turn on / not lock
Initially, each housewife must make sure of the thickness of the bread being laid - thin slices can stall the lifting process if they are deformed during the roasting.
The cause of the malfunction in the toaster may be a commit failure. By clicking on it, in response, you can get not browned pieces, but only the initial position of the lever. The solution can be a stronger press or constant holding in the working position. This happens due to lack of electricity.Here it is necessary to check not only the device, but also the fact of serviceability of the socket, plug and cord. Perhaps they have the root of bad luck, but the fuse can also burn out - it will not hurt to check it in any case. It is important to make sure that the plug is connected correctly and that the wire does not break.
Another thing is when crumbs of bread can simply lie in the groove of the lever, which means that the toaster just needs cleaning: you just need to turn the toaster over and shake it.
If the device does not work when you press the power lever, the reason is simple - there is no power. As in the case described above, you need to check the area of the plug, socket and electrical wire. The oxidized contacts in the control circuit will not allow electric power to pass through. Contact points could simply burn. It will be necessary to open the case and pay attention to the circuit and how they are soldered. In the latches on position, the plates should only be in the closed position, they should not be bent specially.
The use of soldered joints by the manufacturer immediately indicates that the malfunction itself cannot be eliminated.
The spiral does not heat up. Toast toaster control does not work
Among the breakdowns of toasters, it is not uncommon when, after turning on and a few minutes of waiting, not a single piece of bread is fried at the exit, nor the other. Everything is simple here: the matter is a malfunction of one heater or all at once. We will say right away: if the owner knows that instead of spirals there are glass tubes-heaters inside the appliance, it is useless to try to eliminate the cause of the malfunction yourself. But if you deal with the wire structure of the heating element, you can fix it yourself. The spiral could break off or burn out - a plate is removed with a nichrome wire and is inspected.
Nichrome wire break
But all the spare parts that at some point burned out are usually immediately visible in electronic devices.
It also happens that the gap is not noticed externally, but the matter is in the heater, the method of measuring resistance is used using special equipment - a multimeter. A wire break is indicated by zero. Next, the wire is leveled at the cliff, twisted and a bandage from a copper tube is applied to it.
The regulator is of 2 types: electronic and mechanical. The mechanical one is a bimetallic plate, the principle of which is enclosed in the command for opening the contacts at the end of the heating process. Such a plate may be unusable as a result of clogging. It turns out that everything can be repaired by a simple method - cleaned from dust and bread crumbs.
Mechanical regulator
The electronic regulator is a variable resistor that regulates the operation of the timer. Its handle is located in the outer part of the toaster, and if it does not turn, this is a sure sign of the presence of specks in the resistor. In addition, the operation of such a regulator may be terminated because there is no contact with the board. In this embodiment, the wires are checked for strength and serviceability and the contacts are soldered.

Poor toasting
Unfinished toast? Failure occurred in the timer. But also the reasons for which the toaster does not work can be called the excessively low temperature during the cooking process, the skew of the basket itself for slices of bread, and the improperly inserted roasting control. Accordingly, the solution to the problem lies precisely in the correction of the details: install a new regulator or simply correct its position, adjust the board and straighten the guide baskets if there are mechanical damages.
The cause of poor-quality cooking can serve as a bimetal switch. It is necessary to try turning the knob for adjusting the intensity of frying to the position of increasing time.
In the case when the bread is baked from only one side, check the springs that displace the support grids of the basket.The springs can not only be shifted, but also broken. You can replace them yourself: the casing or the outer panels of the case are removed to open access to the springs, which are located between the hooks on the inner metal island. Visually, you need to find those that are broken, out of order.
If there is an obvious smell of burning from the toaster, you need to keep in mind that this is most likely a clogged case due to the use of very soft bakery products. And if the toast began to burn not the first time, it is worth revising the version of the regime on which it is fried. In addition, this is a sure sign that the crumbs in the pallet have accumulated more than permissible.
When only one slice is baked. Manufacturers of some models of the device may initially indicate in the instructions which of the connectors should be used. An improperly selected location can cause the latch to trigger ahead of time.
When the mechanical latch itself is triggered very early, it is possible to detect certain signs of wear on the surface. Replacing can be too expensive, and it may be easier to buy a new appliance.
Can I take apart the toaster and fix it myself?
When disassembling any electrical device, you need to make sure that it is unplugged. This rule will not be an exception for fixing a toaster. It is completely turned off only when the lever is in the raised position, like the basket. As for the circuit breaker, it is operated precisely for the forced breaking of the power supply circuit of the electromagnet.
The electric appliance included for operation is characterized by a heated heating element, slices of bread to be baked are placed in a movable basket. The locking plate holds the basket when the toaster is working, and when it is lowered, the contacts are closed by means of a wedge-shaped plate. The created electromagnetic field acts on the locking strip, which will be attracted to the core - the basket will be locked and the timer will start.
So, to disassemble the toaster, proceed as follows:
- the toaster must be turned upside down and pull out the crumb tray;
- gently remove the lever handle, which usually lowers the basket with slices of bread;
- all screws below are unscrewed;
- you need to push the walls and you can completely remove the tray, after that the walls are removed;
- the next step is to squeeze the petals;
- at the final stage, remove the plate with a heating element.
After that, it is necessary to remove the remaining bread from the guides and the lifting mechanism.
A separate place and time when searching for the cause of a malfunction is always necessary to allocate for inspection of electronic filling. And, if one cannot be found and repaired, you have to take the toaster for repair.
