The design of the unit is simple and reliable, however, and there are problems with it, when it is required to disassemble a toaster and find fault. As a typical example of a device of standard and breakdowns take the simplest model of the "Bosch".
Toaster mounted in a metal or plastic housing, where the fixed heating spiral and the mobile cart with a spring for ejecting the finished toasting. I handed out:
Besides the above structural elements are provided within the following parts:
- the locking device in the form of metal strips, fixing the basket in the lowered position;
- electric magnet, holds the bar in the cooking period;
- Plastic wedge for contact closure after lowering the basket.
Electric apparatus, so mandatory elements are the power supply with the power cord and control the timer settings.
Principle of operation
Before starting the cycle you must set the cooking time. Then proceed as follows:
- Hand push the drive lever that lowers the basket of bread in the bottom position.
- Plastic wedge is lowered and closes the contacts.
- Simultaneously turns the heating element and starts to operate the electromagnet.
- Last locks the cart below.
- A timer is started.
Fried bread, until the timer opens the circuit. Thereafter cart is released and pushes against spring ready toasted.
Required tools
To repair the toaster yourself, with your own hands, fingertips should be:
- Screwdriver crossbar and under it a splined analogue for disassembly and subsequent assembly housing, internal details of construction;
- pliers, which are needed for the same purpose;
- tweezers to remove the spring and hold fasteners;
- multimeter, which is required for the diagnosis of the state of electricians.
Can not do without a clean cloth and brush with bristles of medium hardness. They will be required to clean the inside of the cavity of the crumbs, dust and other debris.
How to disassemble the device
Repair is desirable to start with reading the instructions. Before disassembling the device, Be sure to unplug it from the mains.
dismantling sequence is as follows:
- Open the crumb collection tray and remove the accumulated debris.
- Dismantle the decorative handle of a lever.
- Loosen the screws on the bottom plane of the device.
- Release pallet locks, and remove it.
- Remove plastic wall housing.
- Squeeze tab fasteners metal casing, which is closed heating element.
- Remove the plate from the wound coil.
After dismantling proceed to search for specific faults that need to be repaired.
common faults
Options breakdowns can be set, all to provide and difficult to describe. But there are a number of typical faults, the knowledge of which will help to quickly repair the device.
Toaster not fixed
If the toaster lever is not fixed before the fix, you need to consistently check the possible causes of damage from simple to complex:
- Obstruction due to delayed cleaning tray. Just open the tray and release the inner cavity of the waste.
- Improper temperature control setting, as a result of the solenoid is not getting the nutrition they need and does not hold the lock. It is necessary to put a handle on an average heating mode and press the lever again.
- No network connection. If the device is plugged in, the possible cause of the problem related to the lack of contact in the plug or damage the wires. Another reason may be defective fuse.
In the latter case the device can be repaired by replacing the failed element.
The device is not activated
Heating does not start although the lever is fixed in the lower position. The simplest reason for the lack of power due to a faulty plug or wire. More efforts will require oxidation or burning of contacts. In this case, you need:
- dismantling of the housing,
- cleaning contacts,
- them on the circuit verification.
If the device still does not start, the problem may be hidden in the chain. You need to check all connections and soldering in place of breakage.
Not lit heater coil
When used in the construction of the wire element reason likely to breakage. It requires complete disassembly to access the helix and its visual inspection. In place of failure is applied bandage, the build and check the efficiency. If a visually open could not be found, we use a multimeter.
Not included roasting regulator
A method of repair depends on the type of regulator. Mechanical version often fails due to clogging crumbs. Enough to remove them and check appliance operation. When deformation or breakage of the bimetallic plate, which opens the contacts require expert help.
Electronic control is more difficult to fix - at least need to be able to read the schema. If this skill is not present, it is better not to spend your time and consult a workshop.
Toasts are not fried and undercooked
The simplest cause undercooked or overcooked toasting may be incorrectly exposed temperature. To eliminate it is sufficient to verify the correct settings. It requires more attention:
- basket deformation or rails that have to be straightened after disassembly device;
- failure of the timer should be checked the board and its repair;
- clogging mechanism needs cleaning device from debris and garbage.
A variant of the defect can be a spiral circuit, required his removal or replacement of the heating element.
Frequent breakdowns is sticking and smoke due to the crumbs and pieces of bread. They stick to the heating element and start to burn. Do not let this situation will use a slightly dried bread and timely cleaning of the device.
