DIY toaster repair
Few people in the morning before leaving for work will refuse to eat sandwiches from fragrant bread toasts, baked in toasters. This breakfast will cheer up anyone! However, toasters are also short-lived. They need to take care, regularly maintained. And although the toaster, by virtue of its simple construction, is reliable and easy to use, if it is improperly operated, it can break. At home, it is quite possible to repair the toaster with your own hands, if you know its internal structure, the principle of operation and the main faults.

Device and principle of operation of toasters
Any toaster is simple and is a small electric oven. As for the classic toaster, inside a closed cabinet there are slices for bread slices. They are placed in a movable basket, which is lowered inward, where heating takes place through a spiral. The toaster does not throw out the bread until the timer goes off.
The toaster is shown below:
- Lever arm adjusts the lowering of the basket with slices, and also includes the device itself.
- Nichrome Spiral acts as a heating element that heats the bread slices.
- Stop button is a breaker. With it, you can stop the device at any time before the expiration of the set cooking time.
- Castle.
A switched off device is characterized by a raised lever, a closed breaker and a raised basket. The breaker is used to force an electromagnet in the power supply circuit in case of an unforeseen situation.The working position of the appliance:
- The heating element (nichrome spiral), which is directly involved in the roasting of bread, is heated.
- Slices are put into the moving basket, and it is in them that they are baked.
- With the aid of a striker plate, the basket is held while baking the slices.
- When the basket is lowered, the contacts are closed using a wedge-shaped plate.
After pressing the lever, the basket of bread is lowered. At the same time pushing a wedge plate occurs. spring contacts (9). They are closed, which leads to the launch of the control circuit, electromagnet and heating coils. Due to the created electromagnetic field, the striker plate is attracted to the core, the basket is locked, the timer starts.
The bread is baked by infrared rays until the timer turns off. After that, the control circuit will give a command to remove power from the electromagnet, the lock will release the basket, and with the help of a spring it will rise with slices of bread out. Next spring contacts open and turn off the heating coil.
Frequent breakdowns when using the toaster
Below we consider typical malfunctions of toasters and the reasons for their appearance.
Failure in fixing the lever
It happens that when you press the lever, it is not fixed and returns to its initial position. To fix, you need to press the lever more than once or constantly hold it. Such a problem arises due to the lack of power to the toaster. It is necessary to check the health of the outlet, plug, cable. Perhaps somewhere there is a break or a cable is pinched. If there is a damaged wire, it should be replaced. You also need to check the fuse and replace it if necessary.
One more reason - power shortage for electromagnet. Because of this, the basket is not pressed fully. In this case, you need to set the average position on the controller. Also, the lever can simply become clogged and because of this does not reach the desired position. Way out: clean the cavity from the remnants of the bread, turn the device and gently shake it.
Toaster does not turn on
When you press the lever toaster does not turn on? This may be due to a lack of power supply. Again, you need to check the plug, outlet, wire for serviceability. Also, these problems occur due to oxidized contacts on the control circuit. Therefore, you need to remove the instrument case and carefully examine the circuit. You may have to rewire the contacts.
The spiral does not heat up
If after turning on the toaster and fixing the basket, the spiral does not heat up, most likelythe heater itself is faulty.
It should be noted that in the presence of glass tube heaters in the device, only specialists can help.
In the presence of wire heating element you can act independently. Perhaps he broke off or burned out. In this case, you need to remove the plate with nichrome wire and carefully examine it.
If visually you can not find the place of the cliff, you can measure the resistance with a tester. If there is a break, the tester rate will be zero. How to repair such a breakdown? It is necessary to straighten the wire in places of breakage, twist it, and also impose a bandage, which can serve as a copper tube.
Toast roaster does not work
These regulators are electronic and mechanical. As for the mechanical regulator, it is bimetallic plate. The principle of its operation is to open the contacts after heating. Breakage of the plate may occur as a result of clogging. Therefore, in order to fix the device, you need to disassemble the mechanism and clean it from the bread crumbs.
As for the electronic type controller, it is variable resistor and regulates timer operation. The knob of the regulator is outside.If you cannot turn it, it means that garbage has fallen into the resistor. Also, it may not work due to the lack of contact with the board. In this case, you need to check the wires for serviceability and solder the contacts.
Cooking toast is substandard
The problem arises due to an incorrectly running timer, too low cooking temperature, skew bread basket, incorrectly set cooking regulator. A number of problems can be solved by correctly setting the regulator, adjusting the board, straightening the basket guides in the event of mechanical damage.
If there is a smell of burning, then the problem is most likely caused by clogging or using too soft bread.. You need to clean the toaster and basket.
How to disassemble a toaster with his own hands
First of all, you need to make sure that the device is disconnected from the mains. Then follow the steps.
- The toaster rolls over, pulling out the tray where the crumbs accumulate.
- Removed the handle, lowering the basket for bread.
- The device turns over, unscrew all the screws.
- Walls are moved apart, the tray is completely removed, then the walls are removed.
- Petals are pressed.
- The plate with a heating element is removed.
In conclusion, it should be noted that the analysis of the toaster with his own hands is a fairly simple job. In addition, on the Internet you can find several videos on a given topic. And in order to have fewer problems with this device, it is better to buy toasters from proven companies, such as Tefal or Bosch.
